Vitamin D and our bodies

When sunlight falls on the body’s surface – the skin in our case – it synthesises to form vitamin D3. It is then circulated in the bloodstream and converts to its active form as a hormone in the kidneys. As the body ages, the skin’s ability to convert vitamin D3 into the active form is reduced.Taking daily Vitamin D3 supplements of between 400IU and 2,000IU will maintain healthy vitamin D3 levels and ensure that your body has enough vitamin D3 to enable you to improve your wellbeing. It will also raise blood serums within a few months and allow individuals to benefit from this essential vitamin.

I always got a strange feeling in my head using normal vitamin D tablets of the usual brands. I noticed that when I took SunVit D3, I didn't get any side effects at all. SunVit D3 is a good quality tablet with no nasty ingredients from which I got side effects from other brands. Highly recommend this company.
