Watch this video interview between Dr. Sunil Wimalawansa and Dr. Mobeen Syed as they discuss key aspects of vitamin D and how vitamin D deficiency negatively impacts our health

Key Points

  • Dr. Sunil Wimalawansa’s research with vitamin D began in the early 1980s, when he showed that adding a certain amount of vitamin D can prevent cancer cell growth and revert cells back towards stability
  • In this video interview, Dr. Wimalawansa discusses the safety of vitamin D and the levels needed to help prevent various diseases, as well as who may be at higher risk of deficiency and therefore who may need higher doses of vitamin D
  • Optimal vitamin D levels are essential for optimal functioning of all immune cells; without enough vitamin D, immune cell function is inhibited and disease risk becomes much higher

Measure Your Vitamin D Level


In today’s featured video, Dr. Mobeen Syed of Drbeen Medical Lectures interviews Dr. Sunil Wimalawansa about the key fundamental concepts of vitamin D.

Dr. Wimalawansa has been researching vitamin D for over four decades and is considered one of the world’s leading experts on vitamin D. His extensive background includes working with vitamin D in the laboratory setting from 1983, applying his vitamin D knowledge working with patients as a medical doctor, and facilitating clinical trials involving vitamin D.  He recently collaborated with GrassrootsHealth on a 5-part interview series called “Everything You Need to Know About Vitamin D… and More.”  The video interview below touches on some of these same concepts.

Key Points from the Interview

Dr. Sunil Wimalawansa has been in research for almost 45 years, beginning his work with vitamin D back in 1982

His initial research was on the effects of vitamin D (as calcitriol) on cancer cell lines – he showed that adding a certain amount of vitamin D can prevent cancer cell growth and revert cells back towards stability

Vitamin D is both a vitamin and a hormone, depending on the molecule and its function of use; the hormonal activity of vitamin D is only one aspect of its functionality

Vitamin D can be made in the skin upon exposure to UVB from sunlight, but only under certain circumstances; darker skin needs much more time in the sun than lighter skin to make the same amount of vitamin D

Dr. Wimalawansa discusses the differences between vitamins D2 and D3

The idea that skin exposure to the sun is the cause of melanoma is absolutely incorrect; there is a protective effect of sun and vitamin D on melanoma

Vitamin D has tremendous benefits on the immune system, including helping it generate large amounts of antimicrobial peptides; vitamin D deficiency can contribute to the development of many diseases and acute infections

Dr. Wimalawansa discusses the safety of vitamin D and the levels needed to help prevent various diseases, as well as who may be at higher risk of deficiency and therefore who may need higher doses of vitamin D

Vitamin D is NOT stored in fat for later use…

Important cofactors of vitamin D include magnesium, vitamin K2, omega-3s, and resveratrol – it is important to make sure you are getting enough of each along with vitamin D

Dr. Wimalawansa describes the difference between the endocrine or hormonal effects and the para autocrine effects of vitamin D (calcitriol)
