Tri-Magnesium 100 mg by Nutra BioGenesis

Tri-Magnesium is a modest, flexible magnesium for adults whose intake runs short or whose Magnesium or RBC Magnesium has come back low or low-normal. People who often run low include those on diuretics or long-term acid-suppressing medicines, heavy sweaters, regular drinkers, and anyone eating few greens, nuts, beans and whole grains. If your bowels loosen easily, a glycinate-only product is the gentler choice.

Each capsule supplies 100 mg of magnesium from three forms: magnesium oxide, magnesium malate and magnesium citrate. Oxide packs the most magnesium into a small space but is the least absorbed and the most likely to loosen stools; citrate and malate dissolve and absorb more readily. The label does not say how much each form contributes. Once absorbed, magnesium serves as a cofactor for hundreds of enzymes, including those that make ATP, and it steadies nerve and muscle cells by balancing calcium.

The label directs 1 capsule up to four times daily, or as directed by your healthcare practitioner. That is 100 mg per capsule and up to 400 mg a day. Start with one capsule and add another every few days. Spreading capsules across meals improves absorption and is easier on the bowel than taking them together; people using magnesium for muscle relaxation or sleep often take the last one in the evening.

Take magnesium at least 2 hours apart from levothyroxine, tetracycline or quinolone antibiotics, and bisphosphonates, because it binds them in the gut and lowers their absorption. The kidneys clear magnesium, so anyone with reduced kidney function should use it only under a clinician's supervision. The label asks you to keep your practitioner informed, especially if you are pregnant or nursing.

Loose stools are the usual limit and the signal to drop back a capsule. Cramps and restless sleep, when low magnesium is part of the cause, tend to ease within 1–2 weeks; blood levels take 4–8 weeks, so retest Magnesium or RBC Magnesium after about two months. A mixed-form capsule like this one is a middle path between low-cost oxide and gentler, bulkier glycinate.
