There’s no one-size-fits-all for our vitamin D dose

We all know we need to top up on our vitamin D levels, especially if we’re living in the West—but how much do we need?

Researchers at Trinity College Dublin say one size doesn’t fit all: the dose depends on our body-mass index (BMI) and age.  For instance, as we get older, our body doesn’t process UVB sunlight as efficiently, and so we need higher doses, either from sunlight or supplements.

The optimum dose needs to be tailored to our personal profile, they say.
