Magnesium Citrate Supplements

What people use magnesium citrate for

Magnesium contributes to normal muscle function, the nervous system, and bone health, and citrate is one of the most popular ways to take it. It has an honest dual personality: at everyday doses it's a general magnesium top-up, and at higher doses it draws water into the bowel — which is why magnesium citrate is the form known for helping relieve occasional constipation and supporting regularity.

Citrate vs. other forms

Citrate absorbs well and dissolves well, which is what made it the classic powder form — stirred into water, it goes into solution where some other forms just sink. If you want magnesium's benefits without any bathroom effect, magnesium glycinate is the usual pick. For the full form-by-form comparison, see our main magnesium supplements page.

Powder, capsules, liquid, or gummies

Powder stirs into water or an evening drink and lets you adjust the dose to suit you. Capsules give a measured, consistent dose with no mixing. Liquid calcium-magnesium blends suit people who don't do pills, and gummies are there for anyone who'd rather chew. All four are in the collection above.
