Magnesium glycinate, also known as magnesium bisglycinate, is the most bioavailable and best-tolerated form of magnesium. Unlike conventional forms, it crosses the intestinal barrier without causing digestive discomfort and acts directly on fatigue, stress and sleep quality. That is why more and more people are turning to this specific form to regain their energy and peace of mind.
What exactly is magnesium glycinate?
Magnesium glycinate is a chelated form of magnesium, bound to an amino acid: glycine. This particular chemical bond makes all the difference.
Unlike marine magnesium or magnesium oxide, bisglycinate does not need stomach acid to be absorbed. It passes straight through the intestinal barrier thanks to its natural carrier, glycine.
The Magnesium Glycinate - Stress, Sleep, Anti-Fatigue from Byou Cosmétiques contains 1755 mg of bisglycinate per capsule, providing 350 mg of elemental magnesium. A concentrated format for maximum effectiveness.

- 2-3 capsulesa day is all you need
- 60 capsulesfor a 20 to 30-day course
Why is glycinate better than other forms of magnesium?
Not all forms of magnesium are equal. They differ in their absorption rate and in how well your digestive system tolerates them.
Glycinate stands out for its exceptional bioavailability: your body absorbs up to 80-90% of the magnesium supplied, compared with just 30-40% for magnesium oxide.
| Form of magnesium | Bioavailability | Digestive tolerance | Main action |
|---|---|---|---|
| Bisglycinate | Very high (80-90%) | Excellent | Fatigue, stress, sleep |
| Oxide | Low (30-40%) | Average | Laxative effect |
| Citrate | Medium (50-60%) | Good | Bowel regularity, energy |
| Marine | Variable (40-50%) | Average | Remineralisation |
Key point
Glycinate has no laxative effect, unlike magnesium oxide or magnesium chloride. Ideal if you have a sensitive gut.
How does magnesium glycinate work against fatigue?
Chronic fatigue is often a sign of an underlying magnesium deficiency. This mineral is involved in more than 300 enzymatic reactions, including the production of ATP, the energy molecule of our cells.
Without enough magnesium, your mitochondria struggle to produce energy. The result: physical tiredness, reduced concentration, irritability.
Glycinate offers two benefits at once. On the one hand, magnesium restores cellular energy production. On the other, glycine has a calming effect on the nervous system, reducing the stress that drains your reserves.
Magnesium is the natural anti-stress mineral par excellence: it regulates cortisol secretion and soothes the nervous system.
How is it different from other energy supplements?
Unlike stimulants such as caffeine, magnesium does not create an energy spike followed by a crash. It works at a deeper level on energy metabolism.
For a well-rounded effect, you can combine magnesium glycinate with Maca, an adaptogenic plant that supports vitality and physical endurance.
Other food supplements such as shilajit or Moringa can also boost your overall energy.
What are the signs of magnesium deficiency?
Nearly 70% of the population has an insufficient magnesium intake. Here are the most common warning signs.
- Persistent fatigue from the moment you wake up
- Muscle cramps, twitching eyelid
- Irritability, anxiety, difficulty concentrating
- Sleep problems, waking up during the night
- Frequent headaches
- Increased sensitivity to stress
These symptoms generally disappear after 2 to 4 weeks of regular magnesium glycinate supplementation.
Good to know
Stress, intense physical activity and drinking alcohol or coffee all increase your magnesium needs. Supplementation then becomes essential.
How should you take magnesium glycinate for optimal results?
The recommended dosage is 2 to 3 capsules a day, spread between morning and evening, with a glass of water.
To combat fatigue, take them preferably in the morning and early afternoon. To improve your sleep, take an extra dose 30 minutes before bedtime.
How long before you feel the effects?
The first benefits usually appear within 7 to 10 days: better sleep, fewer cramps, renewed energy.
For lasting results on chronic fatigue and stress, a 2 to 3-month course is recommended. The bottle of 60 capsules provides 20 to 30 days of supplementation.
Can you combine glycinate with other supplements?
Absolutely. Magnesium pairs perfectly with other nutrients for optimal synergy.
Combine it with Pure Marine Collagen to support muscle and joint recovery, especially if you do sport.
To strengthen hair and nails while fighting fatigue, combining it with Biophane is ideal.
Men will appreciate pairing it with Tongkat Ali, a plant that supports male vitality and stress management.
Are there any precautions to take?
Magnesium glycinate is very well tolerated. A few simple rules are all you need.
- Stick to the dosage of 2 to 3 capsules a day
- Store the bottle in a dry place, out of the reach of children
- Food supplements are not a substitute for a varied and balanced diet
- If you are undergoing medical treatment, ask your healthcare professional for advice
Practical tip
Take your capsules with meals to optimise absorption and avoid any digestive discomfort, even though glycinate is very gentle.
Is magnesium glycinate suitable for everyone?
This form is particularly recommended for people with a sensitive gut who cannot tolerate other forms of magnesium.
It is suitable for athletes, people under stress, students during exam periods, pregnant or breastfeeding women (on medical advice) and anyone suffering from chronic fatigue.
Bisglycinate is also favoured by people following a vegetarian or vegan diet, as it contains no ingredients of animal origin.
FAQ
What is the difference between magnesium glycinate and bisglycinate?
They are the same molecule. The term “bisglycinate” simply indicates that two glycine molecules are bound to one magnesium atom. Both names refer to the most bioavailable form of magnesium.
Can you take magnesium glycinate every day?
Yes, daily supplementation is actually recommended to maintain optimal levels. A 2 to 3-month course, which can be repeated several times a year, helps to make up for deficiencies and prevent fatigue.
Does magnesium glycinate make you sleepy?
It does not cause drowsiness directly, but it improves sleep quality by calming the nervous system and regulating melatonin production. You fall asleep more easily and enjoy more restorative sleep.
How long does a bottle of 60 capsules last?
Depending on the dosage you choose, a bottle lasts between 20 days (at 3 capsules a day) and 30 days (at 2 capsules a day). For a full 3-month course, allow 3 to 4 bottles.
Can you open the capsules and mix them into a drink?
Yes, if you have difficulty swallowing capsules, you can open them and mix the contents into a yoghurt, a fruit compote or a glass of water. The effectiveness remains the same.
