Magnesium bisglycinate pairs the mineral with two glycine molecules, an amino acid that eases intestinal absorption. Thanks to this chelated bond, magnesium uses amino acid transport pathways instead of competing with other minerals in the gut — resulting in up to four times higher bioavailability than oxide or marine magnesium, with excellent digestive tolerance even at higher doses.

Magnesium is involved in over 300 essential enzymatic reactions, contributing to normal nervous system function, normal muscle function, bone strength and cellular energy production. The glycine in bisglycinate reinforces magnesium’s calming effect, making it a relevant ally during stress or nervous fatigue.

TRAACS (The Real Amino Acid Chelate System) certifies that every magnesium molecule is fully bound to glycine, forming a genuine chelate structure, verified by spectrometry on every batch — unlike generic products that may label themselves “bisglycinate” while mixing several magnesium forms with only partial chelation.

Take 1–2 capsules a day with a meal and a large glass of water for maintenance. During stress, fatigue or muscle tension, the dose can be increased to 4 capsules a day (300mg elemental magnesium, 80% NRV). Take in the morning for energy and focus, or in the evening for relaxation and sleep.

For adults only. Do not exceed the recommended daily dose. Not recommended for pregnant or breastfeeding women without medical advice. If on medical treatment, particularly antibiotics or bisphosphonates, leave a 2-hour gap to avoid interactions. Store in a cool, dry place away from light, out of reach of children.

How long before I feel the effects?

Early effects on muscle relaxation and sleep quality are often noticeable within the first week; a 4–8 week course is recommended to durably restore body magnesium stores.

Can I take it every day?

Yes — chelated bisglycinate is well suited to long-term daily use, with excellent digestive tolerance and no accumulation effect; excess magnesium is naturally cleared by healthy kidneys.

What’s the best magnesium form for stress?

Bisglycinate is considered one of the best-suited forms, as the glycine itself has calming properties on the nervous system, reinforcing magnesium’s action.
