The best vitamin C serums in the UK for every skin type and budget, tested | Skincare

Published by Sam Flores

Vitamin C is having a moment in skincare because of its ability to gently brighten, reduce pigmentation and support collagen production. It also helps to neutralise free radicals – those unstable molecules generated by UV light and pollution that can lead to premature ageing – making it an essential part of your morning skincare routine (alongside an SPF).

And if so, how do you know which one is right for you? “Individuals with sensitive, reactive or rosacea-prone skin should approach L-ascorbic acid – the most commonly used active form of vitamin C in skincare – carefully, as it can trigger inflammation in compromised skin barriers,” says pharmacist and skincare expert Dr Sonal Chavda-Sitaram. “For these individuals, lipid-soluble derivatives, such as tetrahexyldecyl ascorbate (THD ascorbate), can be transformative. They’re formulated at neutral pH while penetrating deeply and converting to active vitamin C at a cellular level without irritation.” …

Low Vitamin D May Raise Dementia Risk, New Study Finds

Published by Sam Flores

Many people’s vitamin D levels do not fall within a healthy range, which can cause muscle weakness, fatigue, depression, bone pain and lower immune function. In fact, an estimated 60% of the world is vitamin D deficient and needs a supplement, Dr. Michael Holick, a professor of medicine, pharmacology, physiology & biophysics and molecular medicine at Boston University Chobanian & Avedisian School of Medicine, previously told HuffPost. But if that alone isn’t enough to convince you to prioritise getting vitamin D, which you can do through foods like salmon, tuna, and milk, new research published in the journal Neurology this month may do the trick. The study suggests that people with high vitamin D levels in their 30s and 40s have lower dementia risk factors later in life. The study investigates the potential impact of vitamin D levels in early midlife by examining the prevalence of tau protein and amyloid protein in the brain, “which are key hallmarks of Alzheimer’s disease,” Dr. Thomas M. Holland, physician-scientist and assistant professor at the Rush Institute for Healthy …

This Is Exactly How Much Vitamin D3 You Should Be Taking Every Day

Published by Jenni Sidey

Nancy Rodriguez, PhD, RDN, FACSM, a professor of nutritional sciences at the University of Connecticut, says that back in her day, no one was talking about vitamin D supplements. “In the ‘60s and ‘70s, people weren’t slathering on sunscreen. We were basking in the sun with baby oil,” she says. Though such intense sun worship had its own issues (like increasing the risk of skin cancer), it also meant that vitamin D deficiencies among the general population were rare. But these days, most of us work desk jobs and when we do go outside, we slather on sunscreen. While this is great for lowering the risk of skin cancer, it also means that we’ve become a nation of vitamin D-deficient people. According to a 2022 study published in Frontiers in Nutrition, 41% of people in the U.S. don’t get enough vitamin D. Our bodies need vitamin D. The nutrient is responsible for more than 200 functions in the body, including bone strength, dopamine production (key for feeling happy), brain health, and immune support. While getting …

Get the Well Enough newsletter with Harry Bullmore for tips on living a healthier, happier and longer life Get the Well Enough email with Harry Bullmore Get the Well Enough email with Harry Bullmore When the days shorten, and the sun sinks low in the sky, that familiar winter slump sets in. There’s a fundamental reason for this seasonal fatigue: low levels of vitamin D – the “sunshine vitamin”. People in the UK simply can’t make enough of this vital nutrient from sunlight during winter, which is why many are advised to take a supplement. So, what is vitamin D, why does it matter, and how much do you really need? Why is vitamin D important? Vitamin D is a fat-soluble vitamin. This means it’s absorbed with other fats in our diet, and stored in the body’s liver and fatty tissue. Vitamin D helps the body absorb calcium from the gut and regulates calcium and phosphate levels. These minerals are crucial for healthy bones, teeth and muscles. Vitamin D plays a key role in bone …

Does Vitamin D Help You Sleep? I Tried It

Published by Sam Flores

This year, I’ll be trying sleeping tricks to see whether they actually improve my insomnia. Check back in on this series, Rest Assured, to see how I get on. Because I have absolutely no trouble falling asleep, I didn’t realise for years that my 3am wakeups actually constituted a form of insomnia (sleep maintenance insomnia, to be precise). On average, I wake up in the middle of the night just under five times a week. I only return to sleep about a quarter of those times. So, I’ve been trying everything from kiwis to passionflower tea to see whether they have any benefits. Both have stuck, but what about my now months-long habit of taking a daily vitamin D supplement daily? Wait, does vitamin D help with sleep? Some research suggests it might, yes. We know that vitamin D deficiency, which the NHS warns is common in the UK’s gloomy climes from October to about March, appears to be a “forgotten aspect in sleep disorders”. It may cause issues with both sleep maintenance (staying asleep, …

The blue, brown, and sometimes purple discoloration happens when tiny blood vessels just below the skin’s surface burst, leading to blood leakage to the surrounding tissues. While bruising is a completely normal phenomenon, the ease with which you bruise could signal a serious vitamin C deficiency, Paris-based naturopath Lydie Palmieri told Vogue. Vitamin C — found primarily in vegetables such as broccoli, kale and Brussels sprouts, as well as fruits inclduing strawberries, guava and citrus — is an essential antioxidant important for healthy skin, bones and connective tissue, according to Medline Plus. It promotes healing and helps the body absorb iron. “The human body can neither produce nor store vitamin C sustainably,” …

Published by Jenni Sidey

As far as nutrients go, vitamin D is one of the most widely useful—but oft-overlooked—things we put in our bodies. For instance, “there are more than 200 known functions of vitamin D in the body,” says osteopathic physician Ryan Greene, DO. Sure, it’s great for building your bone strength, but it’s also necessary for so many other reasons. This is precisely why you don’t want to have a vitamin D deficiency. Neil Paulvin, DO, a New York-based longevity and regenerative medicine doctor, echoes this sentiment, saying that “vitamin D is extremely integrated into our bodies and helps it in a lot of different ways,” says Dr. Paulvin. Below, we get into what vitamin D is, the symptoms of vitamin D deficiency, and how to provide your body with enough vitamin D for optimal function. What is vitamin D?
