Dr. Michael Holick has been researching vitamin D since 1969.
He was the first to identify the major circulating form of vitamin D in human blood as 25-hydroxy vitamin D3, also known as 25(OH)D3
He isolated and identified the active form of vitamin D as 1,25-dihydroxyvitamin D3, determined the mechanism for how vitamin D is synthesized in the skin, and demonstrated the effects of aging, obesity, latitude, seasonal change, sunscreen use, skin pigmentation, and clothing on vitamin D synthesis
“A Key Question to Answer: Why would Mother Nature have us depend on sunlight to produce vitamin D?” - Dr. Holick.
He was elected as a Fellow for the American Society of Nutrition (ASN), was inducted into the Orthomolecular Medicine Hall of Fame, and has received many awards including The Linus Pauling Prize in Human Nutrition, The General Clinical Research Center’s Program Award for Excellence in Clinical Research from the National Institutes of Health, and more.
In this recent podcast interview with Grassrootshealth, Dr. Holick discusses sensible sun exposure and the benefits to human health. The interview is formatted around 12 key questions relating to vitamin D and sun exposure.
