Vitamin D levels may be linked to the risk of dementia (Image: Getty)
The late Dr Michael Mosley, creator of The Fast 5:2 diet, championed one vitamin in particular for its potential in fending off a prevalent chronic condition. During an episode on his podcast show, Dr Mosley discussed the benefits of vitamin D supplements in preventing dementia with Professor David Llewellyn of Exeter University.
According to them, vitamin D aids in clearing abnormal proteins like amyloid plaques and tau from the brain, which may offer protection against dementia. Dr Mosley, who sadly passed away last year, advocated for vitamin D supplements, believing they could potentially prevent or delay the onset of dementia and Alzheimer’s disease, reports .
In a previous column for the , Dr Mosley shared his personal vitamin D regimen: “I take 25 mcg (1,000 IU), which is within the limits of what’s considered safe (anything under 100 mcg a day for adults or 50 mcg for children, according to the NHS).”
He added: “But closer to the sort of doses studies show you need to take to ward off infections, cancers, and maybe even dementia.”
The NHS deems anything under 100 mcg daily for adults as safe. Dr Mosley also mentioned: “I eat a lot of oily fish and eggs, both rich in vitamin D, and I also go outside for lots of walks, so my vitamin D levels should be well topped up.”
Many vitamin D supplements are reasonably priced. Boots sells 180 capsules for £4, approximately 2p per pill.
In research dating back to scientists found that people with low vitamin D levels faced a worrying 53% heightened risk of dementia, with those severely deficient at an alarming 125% increased risk. Another set of findings in a indicated a 19% to 25% rise in risk for all three types of dementia among those lacking in this essential nutrient.
Adding to the evidence, a third correlated high levels of vitamin D with a fall in the rates of dementia. Cutting-edge research from also suggests that vitamin D supplementation could be instrumental in preventing or delaying dementia, although more rigorous clinical trials are needed to cement these preliminary conclusions.
The warning signs of a vitamin D shortfall are evident and should not be ignored. Common signs of vitamin D deficiency include:
- Muscle pain
- Bone pain
- Increased sensitivity to pain
- A tingling, “pins-and-needles” sensation in the hands or feet
- Muscle weakness in body parts near the trunk of the body, such as the upper arms or thighs
- Waddling while walking, due to muscle weakness in the hips or legs
Dr Mosley underscored in earlier discussions that, aside from its protective role against dementia, vitamin D is pivotal for bone health, aiding the body’s ability to absorb calcium.
He particularly highlighted the UK’s dreary winter months, where daylight scarcity makes it near-impossible for people to produce adequate vitamin D naturally. In these dark times, taking supplements can significantly benefit one’s well-being.
As the cold bites and sunlight wanes during the UK’s winter season, the prominence of vitamin D soars as a guardian of bone and muscle health, potentially diminishing the risk of respiratory infections.
issued advice in a joint statement, stating: “Everyone is advised to take a supplement of vitamin D during winter months.”
It’s crucial to consult your GP before introducing any new over-the-counter medication into your routine. While there are promising studies suggesting vitamin D could combat dementia, it’s important to remember that more clinical trials are needed.
There isn’t a cure for dementia, but various treatments and support options are available to assist those affected. These can range from medication to non-medical therapies, as well as support groups and online communities. While having a family history of dementia can raise your chances of developing the condition, it doesn’t mean you will definitely experience it.
