Dr Michael Holick is a pioneer in vitamin D science and has spent a lifetime researching and exploring what he believes are its potentially life-changing benefits.

He argues that across the world guidelines for the amount of vitamin D we need are simply too low. And that many of us, even those  living in a hot climate, will not be able to get enough vitamin D from sunlight alone.

Dr Horlick contends that not only do we need vitamin D for bone health, we also need it for many other critical functions too. Without a sufficient amount, he says our immune system can’t operate effectively, and that a deficiency of the vitamin is linked to a wide range of other health conditions from heart disease and depression, to auto-immune illnesses and cancer.

In this interview, Michael discusses why he believes vitamin D is so essential and reveals the levels he thinks we all need take for optimal health.
