Vitamin D and B6 boost magnesium absorption — here's what to take together

Magnesium is involved in over 300 enzymatic processes, but its absorption depends heavily on the supplement form, timing and accompanying nutrients. Vitamin D3 and B6 significantly improve uptake, while calcium, iron and excess fibre can hinder it. Experts recommend avoiding these combinations in the same dose and taking magnesium in the evening for best results.
