Vitamin D regulates calcium and phosphate levels, essential nutrients for healthy bones, teeth, and muscles.
Now, scientists suggest taking the supplement daily for four years could slow ageing by helping preserve protective DNA caps, known as telomeres, which shrink as we get older.
Shorter telomeres have been linked to ageing, as well as inflammation, which is associated with autoimmune diseases as well as cancer.
But don't rush out to buy supplements just yet.

The findings need to be confirmed with additional research, the US scientists from Brigham and Women's Hospital and Harvard Medical School, said.
'Dietary supplements will never be a substitute for healthy diet and healthy lifestyle, and we've made it very clear time and again that the focus should be on the diet and lifestyle rather than on supplementation,' Dr JoAnn Manson, a co-author of the study, said.
'However, targeted supplementation for people who have higher levels of inflammation or a higher risk of chronic diseases clearly related to inflammation, those high-risk groups may benefit from targeted vitamin D supplementation," she told The Washington Post.
The study, published in The American Journal of Clinical Nutrition, analysed data from 900 US adults over 50, who took part in the ongoing VITAL trial.

Some were given 2,000 IUs of vitamin D3, others 1g of omega-3 fish oil a day, or a placebo, for four years.
Scientists then measured the length of telomeres in the blood at the start, and again after two and four years.

Previous studies observed a link between vitamin D and longer telomeres, but couldn't prove the vitamin caused the effect.
This latest trial was randomised, double-blind and placebo-controlled - the gold standard of clinical research - making the findings more robust.

Those taking vitamin D3 saw significantly less telomere shrinkage than those who didn't, equivalent to a three-year slowdown in ageing.
Meanwhile, government-funded research has found that more than one in 10 adults in the UK are lacking in the sunshine vitamin.
How can I boost my vitamin D levels?
You can derive a certain amount of vitamin D from your diet, through foods like:
Oily fish – such as salmon, sardines, herring and mackerel
Red meat
Liver (avoid liver if you are pregnant)
Egg yolks
Fortified foods – such as some fat spreads and breakfast cereals
It's recommended that children aged one and above and adults take a supplement with 10 micrograms of vitamin D a day during autumn and winter.

UK's food labelling needs a complete overhaul to combat obesity crisis, health coach claims
A similar scheme in Chile has had a positive impact Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) PCI-QUALIFIED health coach Steve Bennett is calling on British policymakers to adopt bold, front-of-pack food warning labels as part of a national strategy to tackle obesity, affecting approximately 15 million adults in the UK. He praised the black warning labels on ultra-processed foods in Chilean supermarkets, which has led to a measurable decline in sales of these marked products.

'Although well-intentioned, the current traffic light system fails to clearly inform consumers of the health risks associated with ultra-processed foods. 'The system is based on manufacturer-designed portion sizes which are so unrealistic they border on fantasy. When did you last eat just half a biscuit or a single square of chocolate? 'Chile's approach is simple and effective. The introduction of stark black warning labels on foods high in sugar, salt, calories and saturated fat has reduced sales of harmful foods, improved public awareness, and contributed towards a drop in childhood obesity. 'I would expect a similar model in Britain to reflect these results.' Since Chile's policy was introduced, purchases of sugary foods were reportedly cut by as much as 25 per cent. Sales of ultra-processed foods with the labels in school kiosks dropped from 90 per cent to 15 per cent within six months of the law's introduction. Britain currently leads Europe in ultra-processed food consumption, with these products making up over 50 per cent of all food purchases. Steve added: 'Obesity not only increases the risk of heart disease, Type 2 Diabetes and several other diseases, but it also places huge pressure on the NHS and the UK economy. 'Changing our food labelling system and limiting sales of UPFs is a vital step towards tackling this spiralling obesity crisis. 'Addressing the root of the issue is far more effective in the long-term. We shouldn't simply be relying on weight loss jabs to solve the obesity epidemic. 'Transparent labelling would empower consumers to make informed choices and reduce dependence on pharmaceutical solutions. 'The food industry has resisted change, but the evidence is clear, bold labels work. 'I urge the UK government to implement clear warning labels, restrictions on marketing to children and removal of junk food from schools.' Steve, who has created £100 million companies during his award-winning commercial career before becoming a respected health coach, is launching the FREE Clubwell app later in the year to encourage users to keep track of their metabolic health to prevent future health issues related to insulin resistance. 4 Steve is launching a free app to help keep customers informed Credit: Getty

Is your child getting enough sleep? Exact number of hours they need for each age & ideal bedtime so they wake up happy
Plus other tips to help your child go to sleep SLUMBER NUMBER I Is your child getting enough sleep? Exact number of hours they need for each age & ideal bedtime so they wake up happy Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) PARENTS may overlook whether their kids are getting enough sleep when other tasks seem to take over. With summer holidays winding down, parents across the UK are busy preparing their children for the return to school, and it's important to spend the next few weeks resetting routines. Sign up for Scottish Sun newsletter Sign up 2 Mom and son affectionate in the bed Credit: Getty Why you should use a sleep calculator This shift from relaxed summer schedules to early school morning wakeups can be a challenge. And this has been reflected in online search terms, where searches related to children's sleep have seen an increasing. Studies have shown that a good night's sleep is vital for children at school. It optimises their concentration, mood and academic success. A Kids Sleep Calculator devised by Hillarys, determines the best bedtime for different children. It is an easy-to-use tool that presents parents with an ideal bed-time for their child. This is based on age and wake-up time, available just in time for the new school year. Product expert at home interiors brand Hillary's, Yvonne Keal, said: 'As a parent, I know how tough it can be to get kids to wind down at bedtime, especially when it's still light outside. 'We put blackout blinds in my children's rooms, and it really helped them settle more quickly in the evenings and not wake up so early. She revealed the value of using a sleep calculator: 'I also found it helpful to work out a proper bedtime as the new school term approached, and tools like a sleep calculator can be really useful for figuring out what time they should be heading to bed. 'It just makes the whole routine a bit easier for everyone.' How the calculator works The Sleep Calculator for Kids works out the best time for children to wake up by continue sleep cycles. Results of the calculator show wake-up times that are between cycles, described as 'when you're most likely to be greeted with a smile from your child.' The time it takes for children to nod off also needs to be accounted for - which for most is around 14 minutes. This is included in the result of the calculator. Here is how much sleep each age group should get for a good night's sleep. 4 and 5 years old - 10 to 13 hours - 10 to 13 hours 6 to 12 years old - 9 to 12 hours - 9 to 12 hours 13 to 18 years old - 8 to 10 hours Other sleep tips for parents In addition to the calculator, there are also tips parents can use to help their children get a better sleep. Establish a consistent bedtime routine Setting a regular bed and wake-up time is good for consistency, even on the weekend. With a predictable routine, children's body clocks can be regulated. As a result, it makes it easier for them to fall asleep. A calm sleeping environment It is important to create a calm and sleep-friendly environment for children in their bedrooms. Their rooms should be a relaxing space that prioritises sleep. Keeping it tidy, quiet and cool helps in this. Parents should consider using blackout blinds to better facilitate this. They can block out early morning or evening light, which provides a signal to children's bodies that it is time to sleep. Limit screen time Try to turn off screens at before bedtime - ideally at least an hour before. Blue light from electronics like TVs, tablets and phones can interfere with melatonin production, which is the hormone that aids in sleep. Do relaxing activities before bed Encouraging activities like reading a book, listening to calming music or having a warm bath is good for getting read to sleep. It helps children's bodies wind down for the day, rather than keeping them active. Avoid Caffeine and Sugar Parents should watch out for caffeinated drinks or sugary snacks that they give to their children in the afternoon or evening. These foods and drinks make it harder for the body to fall asleep. Keep the cool room and have fresh air It is important to have a well-ventilated, slightly cool room ideally around 16 - 20 degrees celsius. This can be done by opening a window if it is safe to do so.

The 3 natural alternatives to fat jabs weight loss doctor says can crush food cravings and keep you full for hours
WEIGHT loss jabs have soared in popularity in recent months, but while effective for some, aren't a one-size-fits-all solution. For those looking for a more natural route to weight loss, three easy, everyday meals that mimic some of the effects of GLP-1 agonists could be key to you shedding the pounds. More than a million Brits are thought to be on appetite-suppressing weight loss jabs. But according to weight loss doctor Professor Franklin Joseph, head of Dr Frank's Weight Loss Clinic, you don't always need a prescription to get a similar hunger-blunting effect. Certain everyday meals, when built with the right ingredients, can naturally slow digestion, steady blood sugar and send powerful 'fullness' signals to the brain, helping you stay full and beat the urge to snack. Prof Joseph recommends combining high protein, high fibre and healthy fats in the same dish. 'It's the magic trio for appetite control,' he said. 'You feel full sooner, stay full for longer and you avoid the sugar highs and crashes that drive cravings.' Why it works GLP-1 weight loss medications work by mimicking a natural gut hormone that slows stomach emptying and helps you feel satisfied after eating. But certain food combinations can create a similar effect without the needle. 'When you eat a meal rich in protein and fibre, you're naturally extending the time it takes to digest,' Prof Joseph explained. 'Add in healthy fats and you've got a triple lock on hunger. That's why these meals work for people on or off the medication.' Weight Loss Jabs - Pros vs Cons Three GLP-1 style meals to add to your week Protein-packed lentil and quinoa salad 4 A hearty mix of cooked lentils, quinoa, roasted vegetables and a lemon-tahini dressing. 'The plant protein from lentils and quinoa, plus fibre from the veg, keeps you going for hours,' Prof Joseph said. 'It's great as a main meal or batch-prepped for lunches.' Salmon and roasted veggie tray bake 4 Roast salmon alongside non-starchy vegetables like broccoli, peppers and courgette with a drizzle of olive oil. 'You get high-quality protein, omega-3 fats for satiety, and a big dose of fibre,' he said. 'This combination is incredibly filling but still low in calories per bite.' Greek yoghurt parfait with berries and nuts Layer unsweetened Greek yoghurt with mixed berries and a sprinkle of almonds or walnuts. 'It feels like a treat but ticks all the fullness boxes - protein from the yoghurt, fibre from the berries, healthy fats from the nuts,' Prof Joseph said. 'Perfect for breakfast or even dessert.' Prof Joseph added: 'The right plate can make all the difference. "You're not just eating less - you're eating smarter.'
