Analysis-Kennedy's ouster of US vaccine advisers puts pharma ties under scrutiny
By Chad Terhune
(Reuters) -U.S. Health Secretary Robert F. Kennedy Jr.'s surprise ouster of a national vaccine advisory board, claiming it was "plagued with persistent conflicts of interest," puts new scrutiny on the group that recommends which shots should be administered to the American public.
Kennedy said most vaccine experts on the 17-member Advisory Committee on Immunization Practices (ACIP) have received "substantial funding" from drugmakers. He did not provide examples of conflicts of interest for any individual adviser or say how that may have influenced specific recommendations.
Committee members say their work with the U.S. Centers for Disease Control and Prevention follows rigorous vetting of their financial ties. They must abstain from votes on any vaccine for which they have a conflict, as well as any rival to that vaccine or any product from the same manufacturer, according to CDC rules.
The agency's website lists one of the departing panel members as recusing herself over such conflicts.
"To determine that the whole (advisory board), all 17 members, have conflicts of interest, that has not been shown by the evidence," fired board member Dr. Oliver Brooks told Reuters. "However, the decisions that have been made (by Kennedy) undermine confidence in the process and in vaccines."
Six of the vaccine advisers fired by Kennedy received a total of $80 or less from drugmakers from 2017 to 2023, according to a Reuters review of the Open Payments federal database of industry payments to healthcare providers.
Seven other panel members received between $4,000 and $55,000 from drugmakers for consulting, speaking fees, travel or meals over the period 2017 to 2023. Two of those experts had also worked with other scientists in industry-funded research projects worth several millions of dollars.
Brooks, retired chief medical officer at Watts Healthcare in Los Angeles and former president of the National Medical Association, received nearly $44,000 in general payments from Sanofi, according to the government records.
Most of the payments occurred in 2017 and 2018, with nothing after 2020. Brooks became a vaccine adviser in 2021, and did not disclose any conflicts that would preclude him from voting. He said the panel's sole aim is "to prevent vaccine-preventable illness." Sanofi declined to comment.
At least three vaccine advisers were not health professionals tracked by mandatory Open Payments reporting.
KENNEDY'S CONFLICT
Kennedy, who has spent years sowing doubts about vaccine safety and efficacy contrary to scientific evidence, faced questions from Congress about his own potential conflicts of interest during a confirmation hearing.
Kennedy said he would divest his financial interest in litigation against Merck over its Gardasil vaccine, which prevents cancers caused by the human papillomavirus, to his non-dependent, adult son.
In posts on X this week, Kennedy said he would share "examples of the historical corruption at ACIP" and announced eight new panel members. Four of them had received nominal reimbursement for meals, according to Open Payments, while the remainder recorded no payments or weren't covered by the database.
A 2009 federal inspector general's report criticized the CDC for lax enforcement of disclosures among its advisory panels. New research shared with Reuters suggests conflicts have since declined among vaccine board members.
"People are more aware of these issues on advisory committees, so they're facing greater scrutiny there," said Dr. Genevieve Kanter, an associate professor of public policy at the University of Southern California who has studied conflicts among government health advisers.
Kanter's analysis of vaccine panel disclosures found that, on average, 43% of panel members facing decisions on specific vaccines declared conflicts in 2000 compared to 5%, on average, at meetings over the last 10 years.
Kanter said it will also be important to understand how the vaccine advisers assembled by Kennedy are vetted for conflicts. They are due to meet at the end of June.
"We don't want to replace one conflict with another set of conflicts," she said. "If someone has a financial interest in treatments that are believed to be alternatives to vaccines for certain conditions, we want to know that."
DISCLOSURE RULES
ACIP members are required to divest all stock in vaccine makers and stop any active consulting work for those companies before joining the panel. They can't accept travel or food from vaccine companies or collect product royalties. Similar restrictions apply to family members.
Committee members can keep working on vaccine clinical trials funded by industry and those research grants can help cover their salaries. They are required to file annual disclosures and recuse themselves from votes when specific conflicts arise.
"ACIP members ... are carefully screened for major conflicts of interest and selected through a lengthy process," said the California Department of Public Health, whose immunization chief, Dr. Robert Schechter, was fired from the panel by Kennedy.
One of the fired panel members, Dr. Bonnie Maldonado, is a pediatric infectious diseases specialist at Stanford University who has led vaccine studies worldwide.
She participated in research that received $4.65 million in funding from Pfizer, most of it spanning 2021 to 2023. The studies involved vaccines for COVID-19, RSV and other diseases. Maldonado also received general payments from drugmakers, including $26,465 from Pfizer and nearly $7,000 from Merck.
Maldonado abstained from a vote on COVID vaccine recommendations in June 2024, declaring a conflict of interest. In October, she did participate in a COVID-related vote. Maldonado didn't respond to a request for comment.
Noel Brewer, a professor of public health at the University of North Carolina, is not a clinician and therefore not included in Open Payments.
In a 2017 research paper, he disclosed receiving research grants from Merck, Pfizer and GSK and serving on a paid advisory board for Merck. The disclosures did not give details on the payment amounts. Spokespeople for the three vaccine makers were not immediately available for comment.

EPA funds $281,000 to Arkansas to reduce lead in children's drinking water
LITTLE ROCK, Ark. – The Environmental Protection Agency is investing in Arkansas drinking water to benefit children. The $281,000 in funding is to reduce lead in drinking water at schools and childcare facilities. Officials said the funding is in addition to the $200 million it has put into reducing lead in drinking water since 2018. EPA announces rollback for some Biden-era limits on 'forever chemicals' in drinking water In addition to this grant program, EPA's Training, Testing, and Taking Action (3T) program provides information and recommendations to help states and local authorities build voluntary programs to reduce lead in drinking water. Since 2019, this 3T program has helped over 20,000 child care facilities and nearly 13,000 schools have their water tested for lead with over 1,300 child care facilities and 2,500 schools completing remediation work. 'Lead is a neurotoxin that can negatively impact American children,' said EPA Administrator Lee Zeldin. 'With $26 million in funding this year, more schools will be able to identify sources of lead in their water and take action so that our nation's children can focus on learning, playing, and developing skills that will maximize their potential and make our nation stronger.' Trump EPA moves to repeal climate rules that limit greenhouse gas emissions from US power plants The Water Infrastructure Improvements for the Nation Act established the Lead Testing in School and Child Care Program Drinking Water grant in 2016 to award funding to states, territories, and tribes to assist local and tribal educational agencies in voluntary testing for lead contamination in drinking water at schools and child care facilities.

RFK Jr.'s new vaccine advisers include ER doctor who posted Islamophobic commentary online, expert witnesses against vaccines
Among the eight people who Robert F. Kennedy Jr. announced would make up his new group of outside vaccine advisers to the US Centers for Disease Control and Prevention are an emergency physician who posted Islamophobic commentary on social media and two doctors who were paid to provide expert testimony in trials against a vaccine maker. Kennedy, who was himself an influential anti-vaccine advocate before taking the helm at the US Department of Health and Human Services this year, dismissed the previous 17-member Advisory Committee on Immunization Practices, or ACIP, saying the group was 'plagued with conflicts of interest.' He pledged that their replacements wouldn't be 'ideological anti-vaxxers.' Some, though, have been accused of spreading false or misleading information about the safety of vaccines. Among the new members is Dr. Vicky Pebsworth, who holds a Ph.D. in nursing and public health, and who serves as volunteer director of research and patient safety for the National Vaccine Information Center, which advocates for vaccine exemptions and has argued that mRNA Covid-19 vaccines should not be recommended for anyone. Dr. Retsef Levi, a professor of operations research at MIT, has a 2023 post pinned to the top of his account on X that says, 'The evidence is mounting and indisputable that MRNA vaccines cause serious harm including death, especially among young people. We have to stop giving them immediately!' despite studies showing that they are safe and effective and research showing that they have saved millions of lives. Dr. Robert Malone, an early researcher of mRNA technology, has suggested that Covid-19 vaccines may cause cancer, something regulatory agencies say is not the case. Malone also served as a paid expert witness in an antitrust lawsuit over Merck's measles, mumps and rubella vaccine, testifying that plaintiffs compensated him at a rate of $350 per hour. Malone noted at the time that his compensation did 'not depend on the outcome of this litigation or my conclusions.' Fellow new ACIP member Dr. Martin Kulldorff, who has called vaccines 'vital,' served as a paid witness in a vaccine trial against Merck over the safety of its HPV vaccine, Gardasil. The committee's conflict-of-interest policy says members of its work groups 'should agree that they will not serve as a paid litigation consultant or expert witness in litigation involving a vaccine or manufacturer under the purview of the [work group].' Dorit Reiss, a professor of law at UC Law San Francisco, noted that 'past expert witness work may not be a bar, but that's true of the [conflicts of interest] Kennedy used to justify dismissing' the previous members. Kulldorff did not respond to requests for comment about his testimony and whether he would recuse himself from discussions related to Gardasil. Malone also didn't respond to CNN's request for comment. An HHS spokesperson told CNN that the agency 'takes conflicts of interest very seriously' and will 'make sure anyone participating in the meetings do not have any conflicts of interest in the agenda they'll be meeting on.' Several of the new appointees have been in Kennedy's orbit for years. He dedicated his 2021 book, 'The Real Anthony Fauci,' to the 'battle-hardened cadre of heroic scientists and physicians' who fought Fauci's pandemic strategies, including Kulldorff and Malone. He also listed Pebsworth on a 'heroic healers honor roll.' Others are less well-known. Emergency physician Dr. James Pagano doesn't appear to have shared his vaccine views publicly. An X account bearing his name most recently includes supportive replies to posts about President Donald Trump, Elon Musk and Kennedy. About 10 years ago, Pagano posted on the account, 'What's wrong with being an islamophobe? There's so much there not to like.' Pagano didn't respond to CNN's request for comment. A spokesperson for HHS told CNN, 'This was a tongue-in-cheek post made ten years ago that was a reference to the news cycle at the time. It has nothing to do with his qualifications' to serve on ACIP. Pagano is a 'highly qualified medical doctor that will take these issues very seriously.' Caleb Kieffer, a senior research analyst for the Intelligence Project at the Southern Poverty Law Center, called the post 'concerning and problematic, whether it's kind of a one-off or not. … Islamophobia is a recognized form of bigotry. It was a recognized form of bigotry when this was posted in 2015, and it remains a recognized form of bigotry and problem today.' The committee is scheduled to meet June 25 to discuss vaccines for Covid-19, cytomegalovirus, HPV, flu and other diseases. According to the Federal Register, recommendation votes are scheduled for multiple vaccines, including for the Vaccines for Children program, which provides vaccines at no cost to those whose parents or guardians may not be able to afford them. An HHS spokesperson said the new members' ethics agreements will be made public before they start. 'Every ACIP member will be vetted in accordance with their ethics agreement before they are permitted to participate in each meeting agenda item,' HHS Director of Communications Andrew Nixon said in a statement. 'Secretary Kennedy has replaced vaccine groupthink with a diversity of viewpoints on ACIP.' Here's a look at all the new committee members. Hibbeln is a former NIH researcher focused on nutrition and psychiatry, with a particular interest in seafood: He is an unpaid adviser to Positively Groundfish, a nonprofit trade association supporting the fishing industry. Though his vaccine views haven't been made clear, a paper he co-authored in 2018 notes that a connection between a form of mercury in vaccines, thimerosal, and autism 'has been largely repudiated.' Kennedy noted in his X post that, while at the NIH, Hibbeln 'led research on immune regulation, neurodevelopment, and mental health' and that his work has 'informed US public health guidelines, particularly in maternal and child health.' Hibbeln declined to comment when reached by email. Kulldorff was a prominent early critic of the US government's coronavirus response, namely broad shutdowns and school closures, and later the Covid-19 vaccines and what he has argued was federal collusion with social media companies to censor his and others' views. The Swedish epidemiologist and biostatistician teamed up with Oxford professor Dr. Sunetra Gupta and Stanford professor Dr. Jay Bhattacharya, now director of the National Institutes of Health, to write the October 2020 'Great Barrington Declaration,' which argued for fewer social distancing requirements for young, healthy people rather than broad lockdowns. That alliance carried on as Bhattacharya assumed his federal role. Kulldorff's name swirled in the early days of the second Trump administration as HHS officials discussed potential hires around the agencies and appointments to advisory panels, according to a personal familiar with the discussions who asked to remain anonymous because they were not authorized to speak with CNN. Kennedy also seemed to suggest in April that Kulldorff was part of the agency's effort to research the causes of autism. 'This is all being run by Jay Bhattacharya and by, I think, Martin Kulldorff, maybe also working on this, on designing the grant proposals,' Kennedy said April 16. Asked by reporters a few days later about Kulldorff's level of involvement in the autism initiative, Bhattacharya declined to discuss 'any personnel decisions specifically' but added that 'this is public knowledge. I'm very close friends with Martin, and we talk all the time.' Kulldorff wrote in a commentary in the urban policy magazine City Journal that 'vaccines are a vital medical invention' but that clinical trials for Covid-19 shots were not properly designed. He also said he has 'spent decades studying drug and vaccine adverse reactions without taking any money from pharmaceutical companies.' Levi is a professor of operations management at MIT and trained as a mathematician. His bio on the MIT website says he studies food supply chains. He also spent nearly 12 years as an intelligence officer in the Israeli Defense Forces. In an email to CNN, Levi said that he has nearly '19 years of extensive work with healthcare systems and health data,' including 'work on quality and safety of manufacturing of biologic drugs, post marketing safety signal detection, epidemiological models and more generally data driven and statistical/AI enabled frameworks and decision support tools to manage and optimize risk-benefit tradeoffs.' 'I also have been conducting research specifically on the COVID-19 vaccines,' he wrote. In 2022, Levi co-authored a study that looked at the relationship between Covid-19 vaccination rates in Israel and emergency calls for heart problems in teens and young adults. Levi and his co-authors reported a 25% increase in these heart-related emergencies in the early months of 2021 compared with 2019 through 2020. They concluded that this increase was not due to a wave of Covid-19 illnesses — which can cause heart problems — but instead was associated with the timing of the first and second doses of mRNA vaccines in this age group. Observational studies like this one can be misleading because while they may show that two things happen at the same time, they can't prove that one caused the other. In order to prove that vaccines caused an increase in heart-related emergencies in Israel, the researchers would have needed to know the vaccination status of patients in the study and to show that heart-related emergencies increased in vaccinated compared with unvaccinated individuals. The study authors didn't have that information, according to an independent fact check of the study's claims. More recently, Levi has co-authored a study with Florida's surgeon general, Dr. Joseph Ladapo, who in 2024 called for a halt in the use of the Covid-19 vaccine in the state, even for adults over age 65. This new study, which was posted as a preprint — meaning it hadn't been scrutinized by outside experts or published in medical journal — compared death risks in 1.4 million Florida adults who received either the Pfizer or Moderna Covid vaccines in the year after vaccination. The study authors say that they found a higher risk of dying from any cause, and from heart-related causes, in Floridians who received Pfizer's Covid-19 vaccines than in those who received shots from Moderna and that this indicates the vaccines have different 'non-specific' effects. In an email, Levi said that nonspecific effects relate to 'health outcomes broader than and beyond the target virus,' such as deaths from any cause or heart-related deaths. But the study didn't compare death rates in the vaccinated groups with those in people who were unvaccinated. Other studies have found that Covid-19 contributed to excess deaths during the years of the pandemic and to heart-related deaths specifically. The study also didn't account for different dosages in the Pfizer and Moderna vaccines, noted Dr. Peter Hotez, a pediatrician and infectious disease expert who is co-director of the Center for Vaccine Development at Texas Children's Hospital. Moderna's shots had a higher dose of mRNA than Pfizer's: 100 micrograms vs. about 30 micrograms. If the excess deaths were caused by Covid, greater protection from the Moderna vaccines might explain the higher death risk in the Pfizer-vaccinated group, Hotez said. When asked whether the different dosing of mRNA in the vaccines might account for the findings, Levi wrote, 'I think that the hypothesis that Moderna has protective effects against non-COVID deaths and even against cardiovascular deaths, while cannot be fully dismissed, is highly implausible, and not supported by evidence.' In fact, Hotez said, it is supported by evidence. Hotez said in an email that this kind of messaging 'cherry picks a weakly supported factoid, and blows it up until it defies reality but supports their false narrative, while simultaneously ignoring a mountain of counter evidence.' The study authors used the findings to try to sow doubt about the vaccines. In a social media post, Ladapo wrote, 'Did your doctor tell you that you might be more likely to die if you took Pfizer instead of Moderna? That's what we found in Florida, and other studies have shown similar results. The system is rotten and we need more honest scientists.' Although Malone made some key early innovations in mRNA and its potential use in drug therapies, the biochemist has argued in recent years that mRNA-based Covid-19 vaccines are risky and that drug regulators too rapidly authorized their use. In 2023, Malone told House representatives during an event on Covid-19 vaccine injury led by Georgia Republican Marjorie Taylor Greene that he believes mRNA shots can cause cancer, a claim that is not backed by peer-reviewed scientific literature and the FDAand the National Cancer Institute say there is no evidence of a link. Malone's criticisms extend beyond mRNA immunizations. In April, he suggested that a number of measles cases in the current outbreak were caused by the vaccines themselves – although the CDC says they are rare breakthrough cases due to community spread, not cases from shots. In December, he wrote that early polio shots caused cancer because of contamination with the simian 40 virus. The CDC has said that although that virus has caused cancer in some animals, there is no evidence that it caused human cancers. More recently, Malone served as a senior medical adviser to Independent Medical Alliance, formerly known as the Frontline COVID-19 Critical Care Alliance, a nonprofit that pushed back on vaccine requirements and touted unproven coronavirus treatments such as ivermectin. The group celebrated Malone's appointment to the panel Wednesday. Asked whether it had any input with HHS on the new ACIP members, IMA President and Chief Medical Officer Dr. Joseph Varon said in an email that the group 'regularly communicates with HHS on public health issues, including vaccine policy. While specifics aren't disclosed, it's part of their mission to guide such processes.' Of all the new appointees, Dr. Cody Meissner has the most vaccine expertise. He is a pediatric infectious disease expert at Dartmouth University who also has a long history of government service. He previously served on ACIP from 2008 to 2012 and served on the group of independent experts who advised the FDA on its vaccine decisions during the pandemic. He's also been a member of vaccine advisory boards, including for the American Academy of Pediatrics, and was the chair of the National Vaccine Injury Compensation Program. He has co-authored dozens of studies and position statements on vaccines. During the pandemic, he co-authored an editorial in The Wall Street Journal with Dr. Marty Makary, who is now commissioner of the FDA, arguing against the use of masks for kids. He recently told Reuters that he supports Kennedy's decision not to recommend Covid-19 vaccines for pregnant women and healthy children. In a social media post, infectious disease expert Dr. Michael Mina called Meissner a 'rigorous scientist and has defended vaccines' and a 'terrific choice.' Meissner did not respond to CNN's request for comment for this story. Kennedy's post about Pagano notes that he's a board-certified emergency medicine physician with more than 40 years of experience, including service on hospital committees, and is a strong advocate for evidence-based medicine. He appears to be licensed in both California and Florida. In posts on a blog linked to the X account with his name, Pagano wrote in 2017 that it was a 'disappointment' that Republicans failed to repeal and replace Obamacare, and he advocated for 'transparent, cost-based pricing' in health care. Pebsworth is a registered nurse and has a doctorate in health services organization and policy. She has worked in health care for more than 45 years, according to a brief bio that Kennedy posted to X. She's a regional director for the National Association of Catholic Nurses. She has served as a consumer representative to the FDA's Vaccines and Related Biological Products Advisory Committee, or VRBPAC, and on subcommittees for HHS's National Vaccine Advisory Committee, along with other federal and congressional appointments. She has been a board member of the National Vaccine Information Center, a group that says it 'is dedicated to preventing vaccine injuries and deaths through public education and advocating for informed consent protections in medical policies and public health laws.' Articles and videos on its website say that vaccine injuries are common while the benefits of immunizations are questionable, call for more study of vaccines on the childhood schedule and promote the false idea that vaccines cause autism. As part of that group, Pebsworth made 'Ask Nurse Vicky' videos talking about vaccine injuries and informed consent. In one of the videos, she shared that she believes her son was injured by vaccines he received during a routine doctor's visit when he was 15 months old. In 2009, disgraced British physician Andrew Wakefield introduced Pebsworth's son before he sang and played keyboards at an autism dinner. Wakefield helped cause a worldwide panic in 1998 after he published a study suggesting that vaccines cause autism, but many subsequent studies have disproven the link. He was stripped of his medical license in 2010. Wakefield called Pebsworth 'my great friend.' Pebsworth did not respond to CNN's request for comment. Kennedy listed Dr. Michael Ross as a clinical professor at George Washington University and Virginia Commonwealth University, although Ross is not currently employed at either institution. A VCU spokesperson told CNN that Ross was an affiliate faculty member with the School of Medicine's Inova Campus from 2006 to 2021, when the VCU and Inova partnership ended. A spokesperson for GWU said Ross began working at the university in 1979, but he has not had a faculty appointment there since 2017. His LinkedIn lists his work there ending in May 2025. The Virginia-based obstetrics and gynecology physician announced a month ago that he had joined Manta Pharma, a Maryland biotech firm focused on AI-based delivery of therapies for autoimmune diseases, diabetes, drug addiction and HIV/AIDS. Ross' other current employer, private equity group Havencrest Capital Management, describes him as a 'serial CEO' who has served on the boards of multiple private health care companies. On his LinkedIn page, Ross says that while CEO of a generic pharmaceutical company, he engineered the acquisition of a stem cell company 'and an investment in a vaccine company.' Ross previously served as president of CPL Inc., the North American division of Indian generic drugmaker Cadila Pharmaceutical, and was a board member of the Generic Pharmaceutical Association. Ross did not respond to a request for comment on the vaccine company investment and potential recusals while serving on ACIP. CNN's Andrew Kaczynski and Em Steck contributed to this report.

Scientists Find That Taking This Vitamin May Help You Live Longer
Most of us grew up with a vague understanding that 'getting our vitamins' was important, but the reasoning wasn't always clear. A new study dives into the specific health benefits of one vitamin in particular—vitamin D—and its findings show that getting enough of it could be the key to living longer and aging healthfully. Meet the Experts: Joseph Mercola, D.O., board-certified family physician and author of Your Guide to Cellular Health; and Amy Davis, R.D., L.D.N., Live Conscious nutrition consultant. The trial followed more than 1,000 healthy American women over 55 years old and men over 50 for a period of four years and found that, compared to placebo, taking 2,000 international units (IU) of vitamin D3 daily helped slow down the shortening of telomeres. Telomeres are 'protective caps on your chromosomes that naturally wear down with age,' explains Joseph Mercola, D.O., board-certified family physician and author of Your Guide to Cellular Health, and they protect DNA during cell division, a process that the body uses to repair and grow. Every time that happens, they get a bit shorter, which makes them a marker of biological age. 'When telomeres get too short, your cells can't divide properly and start to malfunction or die,' Dr. Mercola adds. 'When they shrink too fast, your risk for things like heart disease, cancer, and premature aging symptoms goes up.' At the start of the study, participants had varied vitamin D levels, and those who took vitamin D3 had more telomere protection than those who didn't after four years. 'That's a measurable slowdown in cellular aging,' says Dr. Mercola. Another group in the study took omega-3 supplements and did not experience the same results. Wondering if you're getting enough vitamin D? The National Institute of Health recommends adults not get more than 2000 IU of vitamin D a day. While the study is promising, and there are others like it, there were a few limitations, including the participant pool lacking broad demographic and health diversity, potentially limiting the strength of the findings, explains Amy Davis, R.D., L.D.N., Live Conscious nutrition consultant. Still, both of our experts do think that, in the way of studies, this one was a pretty solid randomized clinical trial. 'While more studies would help clarify the full picture, this adds real credibility to vitamin D3's role in slowing age-related decline,' Dr. Mercola concludes. Vitamin D is known as the 'sunshine vitamin' that may boost mental and bone health. More research is needed to determine exactly how it slows telomere shortening, but it likely has to do with its anti-inflammatory effects, immunity protection, and its role in cell function, particularly within the mitochondria, explains Dr. Mercola. 'Your mitochondria are the energy factories of your cells, and keeping them healthy helps preserve your metabolic power, your resilience, and even your brain function,' he says. 'Vitamin D also supports the production of glutathione, your body's master antioxidant. That means less oxidative stress, fewer damaged proteins and membranes, and slower wear and tear on your cells.' Research shows that oxidative stress may play a role in everything from cancer to rheumatoid arthritis. Of course, as is the case with any supplementation, you should talk to your doctor before going all-in on vitamin D supplements and make sure you're practicing other healthy habits such as eating a Mediterranean-style diet, exercising regularly, getting good sleep, and maintaining an active social life. Your body gets vitamin D through sun exposure, which you naturally absorb safely in small increments, says Dr. Mercola. (Still, don't skip the sunscreen!) 'Your body is built to regulate how much vitamin D it makes from sunlight,' he adds. 'If you supplement, test your levels first.' Your doctor can draw blood and determine if you have a deficiency and if supplements are needed. You Might Also Like Can Apple Cider Vinegar Lead to Weight Loss?
