Magnesium is an essential mineral: it is involved in over 300 metabolic pathways, from energy metabolism to nervous system regulation, including muscle relaxation.
However, not all forms of magnesium are equal. Magnesium oxide, though common in magnesium salts, suffers from limited magnesium absorption and can cause digestive issues.
Conversely, magnesium bisglycinate offers optimal absorption and exemplary digestive tolerance due to its binding to two glycine molecules, an amino acid.
Why bisglycinate surpasses other forms
-
Chelation with glycine: each magnesium ion is carried by two glycine molecules, facilitating its transport across the intestinal wall.
-
High bioavailability: up to 3 to 4 times more absorbed than oxide or marine magnesium, for maximum digestive comfort.
-
Digestive tolerance: avoids the laxative effects often associated with magnesium oxide.
The main benefits of magnesium bisglycinate
-
Reduction of fatigue
By optimizing ATP production, it supports your daily energy levels. -
Sleep quality
Glycine promotes relaxation and, combined with magnesium, improves falling asleep and deep sleep. -
Muscle and nerve function
It participates in muscle contraction-relaxation and neurotransmitter balance, helping to prevent cramps and nervous tension. -
Synergy with vitamin B6
Often paired, vitamin B6 facilitates the entry of magnesium into cells and enhances its action on the nervous system.
How to incorporate it into your routine?
-
Dosage: 200 – 300 mg of elemental magnesium per day (check label for actual quantity).
-
Timing: preferably take in the evening, after a meal, to maximize the relaxing effect.
-
Recommended course: 2 to 3 consecutive months, then a one-month break before resuming if necessary.
You can adjust your magnesium supplementation according to your needs: physical activity, stress, or sleep disturbances sometimes justify a higher dose.
