FREQUENTLY ASKED QUESTIONS:

Should calcium and magnesium be taken at different times?

While calcium and magnesium can be taken together, some research suggests taking them separately may optimize absorption. If you take high doses of both, consider taking calcium in the morning and magnesium in the evening. For typical supplement doses, the interaction is minimal and taking them together is convenient and safe.

What is the ideal ratio of calcium to magnesium?

A commonly recommended ratio is 2:1 (calcium to magnesium), though some experts suggest a 1:1 ratio may be more appropriate. The ideal ratio depends on your dietary intake and individual needs. Most people get more calcium than magnesium from food, so a magnesium-focused supplement may be beneficial.

Can taking calcium reduce magnesium absorption?

High doses of calcium can compete with magnesium for absorption in the intestines. However, at normal supplement doses (under 500mg each), this competition is minimal. If you take high doses of both minerals, separating them by 2-4 hours may improve absorption of each.
