Magnesium citrate capsules: what the label should show
A clear citrate capsule names the form, the serving, and the elemental magnesium. Here is how to read those lines.

Summary
Magnesium citrate capsules are the straightforward bottle on this shelf: the form is named, the serving is a capsule count, and the number to trust is elemental magnesium. A useful label puts those three facts where you can find them.
A citrate capsule should be boring in the best way. The front says magnesium citrate. The Supplement Facts panel says the serving is two capsules and that those capsules provide 200 mg of elemental magnesium. A 60-capsule bottle is then 30 servings.
That is the whole overview that matters. Citrate is the form. Capsule is the format. Elemental magnesium is the number you carry into a comparison with glycinate or oxide.
Other ingredients
Beside the citrate, expect a capsule shell and a short list of fillers. Cellulose and rice flour are common. This is where you look for colors, allergens, or a blend that never says how much of each ingredient you get. A short list is a better label.

Editorial notes
Pros
- The form, the serving, and the elemental amount can each sit on their own line.
- Two capsules is an easy serving to compare with glycinate or oxide.
- A 60-capsule bottle is a month of daily servings when the serving is two capsules.
Cons
- Not every citrate bottle is 200 mg. Read the panel on the one in your hand.
- Citrate also shows up in laxative products at very different doses. Check that you are looking at a daily supplement serving.
Who may find this format relevant. Readers who want a named capsule and a serving they can count.
The 200 mg figure is the elemental amount for a two-capsule serving in this review. Confirm it on the Supplement Facts panel before you compare prices.
Evidence and limits
Magnesium is an essential nutrient, and citrate is one of the forms used to put it in a capsule. That does not turn 200 mg into the right dose for every reader. The NIH consumer fact sheet is the reference we use for the nutrient. It is not a review of one brand.
We did not run a clinical trial, and this page does not claim a result for sleep, cramps, or stress. The conclusion is about the label: whether you can see the form, the serving, and the elemental amount without doing math the bottle should have done for you.
Editorial conclusion
Choose a citrate capsule when you want that form and you can see the elemental magnesium for the serving. Two capsules and 200 mg is a clear, comparable label. If the bottle only shouts a compound weight, or never says citrate in the facts panel, keep looking.
Put that number next to glycinate and oxide before you decide. The form you will take, at the serving printed on the panel, beats a higher number on a product you will leave in the cupboard.
