Quick answer: Both forms are well absorbed, but they suit different goals. Glycinate is gentle on the stomach and is the form most people choose for sleep and relaxation. Citrate is also well absorbed but can have a laxative effect, so it's often used for occasional constipation rather than bedtime.

Magnesium glycinate

Magnesium bound to the amino acid glycine — well absorbed, stomach-friendly, and commonly used to support relaxation and restful sleep. This is the form in Health Maker's Magnesium Glycinate.

Magnesium citrate

Magnesium bound to citric acid — highly soluble and absorbable, but it draws water into the intestines, which is why it can loosen stools and is sometimes used for constipation. Less ideal right before bed for most people.

So which for sleep?

For an evening, sleep-focused routine, glycinate is usually the better fit — you get the magnesium without the digestive effect. Magnesium contributes to normal muscle and nervous system function (NIH ODS).

Frequently asked questions
