6 Best Magnesium Citrate Supplement Brands: Our Expert Picks

 Magnesium is an important mineral necessary for several enzymatic processes in the body, but dietary surveys show many Americans aren’t getting enough magnesium from food. To get the recommended dosage (310 to 420 mg for adults, according to NIH), your diet should include plenty of green vegetables, spinach, legumes, nuts, seeds, and whole grains. People who rush to work in the morning and get home tired in the evening resort to quick meal options often containing ultra-processed foods. As a result, the amount of magnesium they consume through diet is lower than what’s needed. In such cases, supplements containing magnesium step in to fill the nutritional gap.

Magnesium citrate supplement brands provide elemental magnesium as magnesium citrate. Experts say that this form supports gentle relaxation and bowel regularity. From ultra-pure hypoallergenic supplements to daily-value formulations, here is a list of our top picks for the best brands for magnesium citrate supplements.

What Does It Mean to Take Magnesium as Magnesium Citrate?

When you look at a magnesium supplement bottle, you will see that magnesium is present in several forms. Magnesium in its raw and isolated elemental form is highly reactive. It must be bound chemically to another molecule to be formulated.

In magnesium citrate supplements, pure elemental magnesium is bound to citric acid. Citric acid is a natural compound found in citrus fruits. This specific bonding shapes how magnesium supplement behaves.

Chelation is the process that combines magnesium with citric acid. This chelation should be complete, and the magnesium must be fully reacted. This results in a magnesium form that can be absorbed by the body.

The citric acid molecular has an osmotic effect and naturally draws water into the bowel. This softens stools and stimulates the digestive tract. This working makes magnesium citrate highly effective for promoting natural and predictable daily regularity. Users who want a gentle and natural support for digestion may choose magnesium citrate instead of over-the-counter laxatives, which are known to cause stomach cramps.

Why Experts Prefer Magnesium Citrate Over Oxide?

The cost of a magnesium supplement depends on the form of magnesium it contains. Magnesium citrate supplements are more expensive than those containing oxide. Our experts at Nutriessential say that citrate form is preferred over oxide because it’s more water-soluble and has good bioavailability compared to oxide form.

According to NIH, oxide is poorly absorbed. When there is unabsorbed magnesium oxide that sits in the colon, it can draw water rapidly and that can lead to digestive issues like diarrhea. Magnesium citrate, on the other hand, works as a fast-acting solution without causing digestive distress, supporting bowel regularity and providing magnesium in an easily absorbable form.

At a standard dosage, magnesium citrate can work as an everyday supplement. But, at high doses, it has an osmotic effect pulling water into the bowel. This results in loose stools. Some users experience this when taking magnesium citrate and for them, a much gentler form such as glycinate may be needed. Magnesium citrate is not suitable for all users. Those with compromised kidney function should be highly careful about using magnesium, particularly in citrate form. Magnesium supplements may also interact with other supplements and medications.

Always consult with a healthcare professional to discuss whether magnesium citrate is right for you for your specific health needs.
