Vitamin D Deficiency Linked to Hair Loss and Ageing: Scientist Rates popular Supplements
Suffering from unexplained hair loss or noticing premature signs of ageing? A growing body of research suggests low vitamin D levels could be a key culprit. Now, a leading scientist has assessed a range of popular vitamin D supplements, revealing which ones offer a genuine boost and which are simply a waste of money.
Vitamin D is crucial for overall health, playing a vital role in immune function, bone health, and potentially, maintaining youthful vitality. With many experiencing deficiencies, notably during winter months or with limited sun exposure, supplementation is often considered. But navigating the market can be confusing.This assessment cuts through the noise, providing a fact-based guide to effective vitamin D supplementation.
POWDERED VITAMIN D
M&S Vitamin D3 Powder, £5.73 for one month’s supply
PRICE PER DAY: 19p.
EXPERT VERDICT: At 50mcg (2,000 IU) per dose, this is still under the 100mcg safe limit and contains easy-to-absorb vitamin D3. Powder could be an easier option if you don’t like taking pills, as it can be added to cereal or smoothies. But at £5.73 for just one month’s supply, it is pricey. It also contains erythritol, a sweetener that may cause stomach cramps, diarrhoea and bloating in some people. 5/10
ENRICHED MUSHROOMS
M&S Baby Chestnut Mushrooms, £1.45 for 200g
PRICE PER DAY: £1.45.
EXPERT VERDICT: These are said to be ‘naturally enriched with vitamin D’ by light exposure. When mushrooms are exposed to UV light, they produce vitamin D2, the version that’s less well absorbed. And mushrooms alone are not enough to maintain optimum vitamin D levels.You’d need to consume at least 200g – a whole pack – every day to get the 10mcg minimum. 6/10
FIZZY TABLETS
Holland & Barrett Vitamin D 1,000 IU/25mcg, £4.49 for 20 effervescent tablets
PRICE PER DAY: 22p.
EXPERT VERDICT: These contain the better absorbed vitamin D3. But as with all effervescent tablets the bubbles are created by adding sodium carbonate – basically salt, so not great for people on low-sodium diets, such as those with high blood pressure. They also contain the artificial sweetener sorbitol, which can cause stomach cramps and diarrhoea; and sucralose, which triggers bloating in some. And they’re quite pricey.4/10
