Tri-Magnesium 300 mg by Integrative Therapeutics

If your Magnesium or RBC Magnesium (the inside-the-cell measure) has come back low or low-normal, this is a straightforward, higher-strength way to bring intake up. People who commonly run short include long-term users of acid-suppressing medicines or diuretics, heavy sweaters, regular drinkers, and anyone whose diet is light on greens, nuts, beans and whole grains. Two of its three forms loosen the bowels at higher doses, so it also suits people who tend toward constipation.

Each capsule combines three magnesium salts: citrate, oxide and malate. The label gives the total, 300 mg of magnesium, not how much comes from each. Citrate and malate are organic salts that dissolve and absorb well. Oxide packs a lot of magnesium into a small space but is absorbed less completely, and what stays in the gut draws water into the bowel. Magnesium itself is a cofactor for hundreds of enzymes, including those that make ATP (cellular energy), and it helps nerves and muscles settle after they fire.

The label directs adults to take 1 capsule once or twice daily, or as a healthcare professional recommends. One capsule provides 300 mg of magnesium; two provide 600 mg. Start with one, with a meal, and stay there unless your clinician wants more: the adult upper limit for magnesium from supplements is 350 mg a day, set on its laxative effect, so two capsules is a dose to take with guidance. If you do take two, split them between a morning and an evening meal.

Magnesium binds some medicines in the gut. Take it at least 2 hours apart from levothyroxine, tetracycline and quinolone antibiotics, and bisphosphonates (bone medicines). If you have kidney disease, do not take it without your clinician's oversight: the kidneys clear magnesium, and levels can build up when they work poorly. Loop and thiazide diuretics and long-term proton pump inhibitors lower magnesium, which is a reason to test, not to guess at a dose. If you are pregnant, nursing or taking any medications, check with a healthcare professional first.

Loose stools are the common side effect and the sign to drop back to one capsule or take it with more food. Blood levels move slowly, so retest Magnesium or RBC Magnesium after 4–8 weeks of steady use. Compared with a single-form product, this blend trades some gentleness for strength per capsule. Choose glycinate if you want the least bowel effect; stay with this one if a single capsule a day is what you are after.
