Want to reverse age? THIS powerful supplement might do the trick
Humans are obsessed with freezing time, especially when it comes to aging. Though aging is a natural process, the quest to slow it down, or even reverse it, never ends. For centuries, scientists have been working on slowing down the aging process.
Now, new research has found that a certain vitamin could offer protection against biological aging. The nutrient in the spotlight is vitamin D
In a groundbreaking study published in
The American Journal of Clinical Nutrition
, the researchers found that vitamin D supplementation helps maintain telomeres, protective caps at the ends of chromosomes that shorten during aging and are linked to the development of certain diseases. The study is based on the data from a VITAL sub-study co-led by researchers at Mass General Brigham and the Medical College of Georgia.
'VITAL is the first large-scale and long-term randomized trial to show that vitamin D supplements protect telomeres and preserve telomere length. This is of particular interest because VITAL had also shown benefits of vitamin D in reducing inflammation and lowering risks of selected chronic diseases of aging, such as advanced cancer and autoimmune disease,' co-author JoAnn Manson, MD, principal investigator of VITAL and chief of the Division of Preventive Medicine at Brigham and Women's Hospital, a founding member of the Mass General Brigham healthcare system said in a statement

These protect the ends of chromosomes from degrading or fusing with other chromosomes. Telomere shortening is a natural part of aging and is associated with an increased risk of various age-related diseases.
Previous short-term studies have suggested that
vitamin D
or omega-3 fatty acid supplementation may help support telomeres, however, the results have been inconsistent. The VITAL was a large, five-year trial that tested vitamin D3 (2,000 IU/day) and omega-3 fatty acid (1 g/day) supplementation in US females aged 55 years and older and males aged 50 years.
The sub-study had 1,054 participants, whose telomere length in white blood cells was assessed at baseline in the second and fourth years.

They found that people who took vitamin D3 supplements significantly reduced telomere shortening over four years, preventing the equivalent of nearly three years of aging compared with those who didn't. Omega-3 fatty acid supplementation, however, had no significant effect on telomere length throughout follow-up.
'Our findings suggest that targeted vitamin D supplementation may be a promising strategy to counter a biological aging process, although further research is warranted,' Haidong Zhu, PhD, first author of the report and a molecular geneticist at the Medical College of Georgia, Augusta University, added.
Sunlight is the most effective way for the body to produce vitamin D naturally. When the skin is exposed to ultraviolet B (UVB) rays from the sun, it produces vitamin D. Some foods are also rich in vitamin D. These include fatty fish such as salmon, mackerel, sardines, tuna, herring, and trout. Red meat, egg yolks, liver, and cod liver oil are also good sources of the vitamin.

Scared of needles? AstraZeneca launches FluMist Home nasal spray delivery
Are you one of those people whose whole world starts buzzing and spinning as soon as they see a needle? Well, your trypanophobia (phobia of needles) won't stand in the way of your getting a flu shot to protect your health this fall. How? AstraZeneca now allows Americans to skip the doctor's office and pharmacy lines for their flu vaccine, with no needle required. No phlebotomy, no lines, and way less 'omg-this-is-gonna-hurt.' It's FDA-approved, easy as sniff-and-spray, and ready to deliver – straight to your door. With the launch of FluMist Home, a program that delivers the flu nasal spray directly to your door, you can now get your flu shot sitting on the couch in your PJs. FluMist Home: The game-changer for couch-cruisers What's new this flu season? It's AstraZeneca's game-changer, called FluMist Home: the first-ever at-home nasal spray flu vaccine you can order online. FluMist is a nasal spray influenza vaccine that's been FDA-approved since 2003 and works just as well as the traditional flu shot in preventing infection and serious illness. Previously, you had to get it from a healthcare provider. But with FluMist Home, that has changed. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Beyond Text Generation: An AI Tool That Helps You Write Better Grammarly Install Now Undo Dr. Ravi Jhaveri, pediatric infectious disease specialist, told the NY Post, 'This will be the first time someone will be able to give themselves a flu vaccine right in their own home,' adding, 'While that may seem intimidating, this is an incredible milestone to make vaccines more accessible.' How safe is it to use at home To gain FDA permission, AstraZeneca conducted a study requiring users to self-administer, or give, to a child using provided instructions. The result: a 100% success rate. Each kit contains: Clear written instructions Instructional videos Access to a toll-free pharmacist call center A pharmacist chat feature for live support How FluMist works Visit and complete a medical screening questionnaire. If approved, you'll choose a delivery date. The vaccine arrives in an insulated package with cooling packs to keep it safe. A licensed provider reviews your info and verifies insurance.

It comes with how-to videos, written directions, and pharmacist support just a click or call away. Dispose of the used sprayer using the prepaid envelope. Easy peasy! AstraZeneca even reports a 100% success rate in self-administration studies. The service is available in 34 states, with plans to expand further. If your state isn't included yet, flu spray is still available at clinics and pharmacies. Who can use FluMist Home? Adults aged 18 to 49 can self-administer. Parents or caregivers can give the spray to children aged 2 to 17. 'Giving the vaccine at home, to yourself or your children, makes protection more accessible, convenient, and better aligned with people's busy lives,' said Jhaveri to the NY Post. He added, 'If your little one fears needles, your doctor's appointments are hard to get, or you juggle work and school schedules, this might be the perfect choice this season.' However, it is not suitable for those over 50, pregnant, immunocompromised, or with certain conditions like asthma, egg allergy, aspirin use, or GBS history. You're advised to check with your doctor in case of worries. Why flu shots still matter The 2024-2025 flu season was one of the worst in 15 years, with over 47 million cases, 610,000 hospitalizations, and 27,000 deaths, including 216 children. Vaccination rates are slipping: among children under 18, fewer than half were vaccinated, down from 62.4% pre-pandemic. Jhaveri emphasized, 'I strongly encourage flu vaccination, whether you've done it before or not, it remains one of the most effective ways to prevent flu,' adding, 'Children face serious risks, like pneumonia or hospitalization, and 150-200 children die each season, many of whom were otherwise healthy.' He concluded, 'I recommend getting vaccinated by the end of October, before flu season ramps up. It's vital to protect yourself, your family, and your community. '

Widespread malnutrition in Gaza: Palestinian woman Marah Abu Zuhri dies in Italy; was evacuated on humanitarian flight
AP file photo A Palestinian woman, who was evacuated from Gaza to Italy for treatment after suffering from extreme malnutrition, has died at a hospital in Pisa, officials said. Marah Abu Zuhri, 20, traveled with her mother to Pisa on an overnight flight on Wednesday as part of an Italian government evacuation programme. The University Hospital of Pisa said she went into cardiac arrest and died on Friday, less than two days after her arrival. She had a 'very complex clinical picture' and was 'in a profound state of organic wasting,' stated doctors of the hospital, as per the Guardian. The hospital did not provide further details about her condition, but Italian news agencies, citing medical sources, reported that she had been suffering from severe malnutrition. Thirty-one patients and their companions arrived this week in Rome, Milan, and Pisa, many suffering from severe congenital conditions, injuries, or amputations, as per the Italian foreign ministry. Since the start of the war between Israel and Hamas, Italy has evacuated and received more than 180 children and young people from the besieged Gaza Strip. The UN has raised alarms over widespread malnutrition in Gaza, with experts supported by the organisation warning in a report last month that a 'worst-case scenario' of famine is already unfolding. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The 5 Books Warren Buffett Recommends You To Read in 2025 Blinkist: Warren Buffett's Reading List Undo The UN World Food Programme reported in July that one-third of Gaza's population endures days without food, while around half a million people are facing imminent starvation. 'The worst-case scenario of famine is currently playing out in the Gaza Strip,' said the Integrated Food Security Phase Classification (IPC) last month urging an immediate ceasefire to ease 'widespread starvation.' Israel's defence ministry said that it will start supplying Gaza City residents with tents and other equipment on Sunday ahead of relocating them to designated 'safe zones'. The announcement came shortly after the government confirmed plans to occupy Gaza City, followed by days of intense bombardment in Zeitoun, the city's largest district. The situation in Zeitoun was 'catastrophic', a municipal spokesperson was quoted as saying by the BBC, citing mass displacement after six consecutive days of heavy Israeli airstrikes, shelling, and demolitions. There have been more than 250 instances of hunger-related deaths in the war-ravaged territory since the start of the conflict in October 2023. Eleven people died from malnutrition last week, as per the health ministry. 'There is no policy of starvation in Gaza, and there is no starvation in Gaza,' Israeli prime minister Benjamin Netanyahu said last month.

Shukla's backup astronaut, Prashanth Balakrishnan Nair, also returned to the homeland. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Crossout 2.0: Supercharged Crossout Play Now Undo Shukla is expected to meet Prime Minister Narendra Modi and travel to his hometown, Lucknow, shortly. He is also expected to return to the capital to participate in the National Space Day celebrations on August 22-23. India's space glory touches Indian soil... as the iconic son of Mother India, #Gaganyatri Shubhanshu Shukla, lands in Delhi in the early hours of this morning. Accompanying him, another equally accomplished Group Captain Prashanth Balakrishnan Nair, one of the astronauts selected for India's first human mission Gaganyaan , who was India's designated backup for the mission to the International Space Station #ISS," Singh said in a post on X. Live Events Earlier on Saturday, Shukla had posted a smiling photograph of himself sitting in an aeroplane on Instagram, saying he was filled with mixed emotions as he left the US and looked forward to returning to India to share his experiences with everyone back home. "As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past year during this mission. I am also excited about meeting all my friends, family, and everyone in the country for the first time post-mission. I guess this is what life is - everything all at once," Shukla said in the post. "Having received incredible love and support from everyone during and after the mission, I can't wait to come back to India to share my experiences with all of you. Goodbyes are hard, but we need to keep moving in life. As my commander Peggy Whitson fondly says, 'The only constant in spaceflight is change.' I believe that applies to life as well," he added. Shukla also wrote, "I guess at the end of the day - 'Yun hi chala chal rahi - jeevan gaadi hai samay pahiya'," recalling the song from the Bollywood movie Swades, which was on his playlist just before he embarked on the Axiom-4 mission to the ISS on June 25 from the US. Shukla and his backup astronaut Prashanth Nair participated in the Independence Day celebrations at the Indian Consulate in Houston on Friday. Addressing the 79th Independence Day celebrations at the Red Fort, Prime Minister Narendra Modi on Friday said India was developing its own space station and noted that Group Captain Shubhanshu Shukla had returned from a space mission. "Our Group Captain Shubhanshu Shukla has returned from the space station. In the coming days, he is returning to India," Modi had said. Shukla was part of the Axiom-4 private space mission that lifted off from Florida on June 25 and docked at the International Space Station on June 26. He returned to Earth on 15 July. Along with three other astronauts - Peggy Whitson (US), Slawosz Uznanski-Wisniewski (Poland), and Tibor Kapu (Hungary) - Shukla conducted over 60 experiments and 20 outreach sessions during the 18-day mission.
