To enjoy all of the benefits vitamin D can provide, you not only need to get enough of it, but it also needs to be properly absorbed. The mistake millions of vitamin D supplement buyers make, is ignoring the critical role the essential mineral magnesium plays in vitamin D absorption.
Simply put, the bioavailability of vitamin D depends on magnesium. The enzymes in the liver and kidneys that enable vitamin D metabolism can’t work without sufficient amounts of magnesium to draw upon.
And research shows that up to 50% of adults are magnesium deficient.†
So, in order for a vitamin D supplement to provide the full benefits, it must include a research-based dose of magnesium as well.
