Magnesium glycinate 22% capsules are a highly bioavailable oral dietary supplement formulated to deliver elemental magnesium bound to the amino acid glycine. The "22%" designation specifically refers to the elemental loading matrix, meaning that approximately 22% of the total magnesium glycinate compound weight consists of pure, usable elemental magnesium. For example, a capsule containing 650 mg of this chelated compound provides roughly 143 mg of active elemental magnesium.
Key Therapeutic Benefits
-
High Bioavailability & Intestinal Bypass: By chemically bonding magnesium to glycine, the molecule forms a stable chelated ring. This structure protects it from breakdown by stomach acid, allowing it to be absorbed via alternative amino acid pathways (PepT1) rather than standard mineral paths.
-
Superior Gastrointestinal Tolerance: Unlike forms like magnesium oxide or citrate, magnesium glycinate is considered a non-laxative formula. It rarely causes abdominal cramps, bloating, or diarrhea because it does not draw excess water into the bowel.
-
Neuromuscular Decompression: It actively supports muscle fiber relaxation, helping to alleviate nighttime leg cramps and restless muscle twitches.
-
Nervous System & Sleep Support: Glycine acts as an inhibitory (calming) neurotransmitter. The combination supports deep sleep, anxiety management, and nervous system balance.

Clinical Considerations & Safety
-
Standard Dosing: The typical recommendation is 1 to 2 capsules daily taken with a glass of water after a meal. For targeted sleep and muscle relaxation support, it is best consumed roughly 40 minutes before bedtime.
-
Renal Contraindication: Individuals with advanced renal insufficiency or kidney disease should not take this or any magnesium supplement without strict medical supervision. Impaired kidneys cannot effectively filter mineral loads, increasing the risk of dangerous hypermagnesemia (which can cause severe low blood pressure or irregular heart rhythms).
-
Drug Interactions: Magnesium can bind to and decrease the absorption of certain medications, such as bisphosphonates and tetracycline/fluoroquinolone antibiotics. Doses should be separated by at least 2 to 4 hours.
