Magnesium Bisglycinate

Our Magnesium Bisglycinate is a dietary supplement providing 300 mg of elemental magnesium per day, primarily in a chelated form—magnesium bisglycinate—combined with 120 mg of taurine and 1.4 mg of vitamin B6 in its active form (pyridoxal-5-phosphate), delivered in 3 plant-based capsules made in France 🇫🇷.

Magnesium is an essential mineral that the body cannot produce on its own. It is involved in over 300 enzymatic reactions, from energy metabolism to nerve transmission ⁽³⁾, and contributes to reducing fatigue, the normal functioning of the nervous system, and normal muscle function ⁽¹⁾.

Yet our diets do not always keep up. In the French SU.VI.MAX cohort, 77% of women and 72% of men had magnesium intakes below recommended levels ⁽²⁾. Whole grains, nuts, seeds, and legumes: foods rich in magnesium remain the primary source. When food alone falls short, a well-formulated supplement can bridge the gap.

To help secure your daily intake, we selected bisglycinate—magnesium bound to glycine, an amino acid—a form that is better absorbed than inorganic forms such as magnesium oxide ⁽³⁾. We paired it with taurine and vitamin B6 in its active form, and we share the complete breakdown of every batch, certificate of analysis included.

An easy step to add to your daily routine: 3 capsules per day with a meal, for a 40-day supply (120 capsules).

Our Magnesium Bisglycinate is designed for adults looking to support their daily magnesium intake. It may be particularly suitable for you if you relate to any of the following situations:

• You are going through a busy or demanding period
  Long workdays, meals on the go, little time to cook: nutrition often takes a back seat. Magnesium and vitamin B6 contribute to the reduction of tiredness and fatigue and to normal psychological function ⁽¹⁾. Discover also our supplements for fatigue.
• You exercise regularly
  Physical exertion demands magnesium, which contributes to normal muscle function and electrolyte balance ⁽¹⁾. Part of it is also lost through perspiration. Discover also our sports supplements.
• You follow a vegetarian or vegan diet
  Our capsules are 100% plant-based and the formula contains no ingredients of animal origin.
• You are over 50 years old
  Dietary magnesium intake is frequently below recommended levels in adults ⁽²⁾; a supplement can help secure your daily needs. If you are currently undergoing medical treatment, consult your doctor.
• You are pregnant, breastfeeding, or on long-term medication
  Your doctor or midwife is in the best position to assess your specific requirements: seek their advice before starting any supplementation.

Directions for use: 3 capsules per day with a large glass of water, preferably with a meal. They provide 300 mg of elemental magnesium.

When to take: Take all at once or spread throughout the day, whichever suits you best. Consistency matters more than the exact time: if you're unsure, read our guide on when to take magnesium.

Duration of use: 1 to 3 months, repeatable as needed.

Formats: 120 capsules for a 40-day supply, or 60 capsules for 20 days.

Our tip: Pair your intake with a set meal each day so you never miss a dose. Subscribe for automatic deliveries at 10% off, cancel anytime.
