People with optimum vitamin D levels can expect better health across the board – longer life, reduction in death rates from all causes (including cancer), fewer diseases, stronger bones and muscles, fewer and less severe infections, less depression, pain and inflammation. In short, more life and more enjoyment of it.
It’s also a skin vitamin. Findings show vitamin D may be vital in keeping your hormones balanced, and therefore to maintaining clear, beautiful skin. Vitamin D is also useful in controlling blood sugar levels and when your blood sugar is level, your skin looks better.
It’s also an anti-ageing vitamin because vitamin D helps to control hormone and insulin levels and this may affect how your skin ages, how far into older age you get with great skin, and how your skin looks today.
If your body cannot produce enough vitamin D because of insufficient sunlight exposure or any other factors, you need to obtain it from foods and/or supplements. Experts say that people with a high risk of vitamin D deficiency should consume 25 μg (1000 IU) of vitamin D each day so that there is a good level of 25-hydroxyvitamin D in the bloodstream. (Elderly people, as well as people with dark skin should consume extra vitamin D for good health.)
A 25-hydroxy vitamin D test is one that any health practitioner who can order blood tests will be able to get for you and it will indicate where your levels are. Just remember that Vitamin D supplements can be toxic if taken at high doses (just like many other single nutrient supplements.)
So I would say ensure your levels are optimum to anti-age your body in so, so many ways.
