NOW Magnesium Glycinate Veg Capsules, 180 Count — Chelated Magnesium with BioPerine for Gentle Absorption

NOW Magnesium Glycinate with BioPerine is a highly absorbable magnesium supplement formulated with the amino acid glycine and a black pepper extract to support efficient uptake.

This 180-count bottle delivers magnesium chelated to glycine, a form chosen to help improve intestinal tolerance and absorption. Enhanced with BioPerine®, a standardized black pepper extract, the formula is designed for daily mineral support in an easy-to-swallow vegetarian capsule. NOW manufactures to GMP standards and performs in-house testing to maintain consistent potency and quality.

How does this magnesium form differ from other magnesium supplements?

Magnesium glycinate pairs magnesium with glycine, an amino acid that helps stabilize the mineral for gentler digestion and often better bioavailability than oxide or carbonate forms. Because it's chelated, it tends to have fewer gastrointestinal side effects and is a common choice when steady magnesium levels are desired.

• Magnesium is bound to glycine for increased stability and absorption
• Less likely to cause digestive upset than some inorganic magnesium salts
• Delivered in vegetarian capsules for broader dietary compatibility

What does the BioPerine® addition do for this supplement?

BioPerine® is a black pepper extract standardized for piperine, included to support the body’s ability to absorb certain nutrients. In this formula, it is added at a level intended to complement magnesium uptake without adding stimulants or fillers.

• Standardized piperine extract to support nutrient uptake
• Formulated at low levels to enhance absorption without added stimulants
• Non-GMO source and commonly used in dietary supplement formulations

How should I use NOW Magnesium Glycinate for best results?

The suggested use is two capsules once or twice daily with food, allowing you to tailor intake to your needs and tolerance. Taking magnesium with meals can reduce the chance of gastric discomfort and helps integrate the supplement into routine daily nutrition.

• Suggested serving: 2 capsules 1–2 times daily with food
• Split doses across the day if higher intake is desired
• Store in a cool, dry place away from direct sunlight
