Can I take Magnesium and Vitamin d together?

Why this happens

This is a 'synergistic' interaction. Magnesium is a necessary 'co-factor' for the enzymes that convert Vitamin D into its active form in the blood. Without enough magnesium, Vitamin D may remain stored and inactive. Conversely, Vitamin D can slightly increase how much magnesium your intestines absorb.

What you should do

It is usually fine and often recommended to take these together. However, if you have kidney disease or are taking high-dose supplements, you should speak to your doctor or pharmacist first to ensure your dosages are appropriate for your needs.
