Lots of us need it, but is there a safe way to take it?
Vitamin D has many health benefits including common skin, heart and chest conditions, as well as being protective against dementia. The Vitamin D Council Health Conditions have collated lots of the most recent research in over 45 different health conditions on the benfits of vitamin D.
Supercharging Vitamin D3 with Vitamin K.
Vitamin D3 has many beneficial anti-ageing effects. Many of these effects are boosted by the presence of vitamin K. This key vitamin works alongside vitamin D to make bones stronger. It stops bone reabsorption and increases bone density. It will also stop calcium depositing in artery walls. Many mechanisms have been suggested, but it seems that they work to reduce inflammation, so-called “inflammaging”, to promote health. Here is a link to a recent article on vitamin K: Vitamin K as a Powerful Micro-nutrient in Aging and Age-Related Diseases: Pros and Cons from Clinical Studies Sept 2019
High levels of vitamin D will increase calcium in the body and blood by increasing absorption from the gut. As long as there is enough calcium in the diet this is fine. The presence of vitamin K, however, is important to keep this calcium “in the right place” to avoid calcification of arteries. In summary, vitamin D increases the calcium and vitamin K helps to put it to work.
There are subtleties to maximising these health benefits and most importantly doing no harm. At high doses of vitamin D, if the diet is deficient in calcium and vitamin K, it will sometimes decrease calcium in the bones, therefore weakening them. When taking vitamin D, make sure you take a supplement that also contains about 100mcg of vitamin K2. High quality supplements tend to combine vitamin K2 with vitamin D. Otherwise this can be taken separately.
