Nutravita Magnesium Bisglycinate

Check the exact bottle rather than relying on the catalog name, because Nutravita sells multiple magnesium formulas. Its Magnesium Complex, for example, combines bisglycinate with citrate, malate, ascorbate, and magnesium oxide.

Use the serving stated on the specific package because capsule strengths differ between Nutravita products. Do not treat the compound weight, such as milligrams of magnesium bisglycinate, as the same thing as elemental magnesium.

Bisglycinate is magnesium bound to the amino acid glycine and is often selected because it tends to be gentler on digestion. Magnesium oxide contains more magnesium by weight but is more likely to have a laxative effect.

Magnesium can reduce the absorption of medicines including levothyroxine and some antibiotics if taken too close together. A pharmacist can advise on spacing, particularly for tetracycline or quinolone antibiotics.
