Types of magnesium in this article
Magnesium glycinate (bisglycinate)
Absorption ~80%Compound of magnesium with the amino acid glycine. One of the most absorbable forms of magnesium, and at the same time the gentlest on digestion — suitable for sensitive intestines. Glycine also supports the nervous system: reduces anxiety, helps fall asleep, stabilizes mood. Suitable for insomnia, PMS, and increased anxiety. Well tolerated by pregnant women.
- Helps with insomnia: the glycine in the formula acts as a mild sedative, helping you fall asleep faster and improving sleep quality.
- Reduces anxiety: suitable for people who often feel nervous, restless, and cannot relax in the evening.
- Reduces stress levels: decreases irritability, mood swings, and negative reactions.
- Does not irritate digestion: does not cause side effects from the stomach or intestines even with long-term use.
- Suitable for pregnant women: one of the few forms of magnesium recommended during pregnancy due to its gentle action.
Magnesium taurate
Absorption ~80%Compound of magnesium with the amino acid taurine — a specialized form for the heart and blood vessels. Taurine helps regulate heart rhythm, reduces strain on blood vessels, and decreases sensitivity to stress. Used for high blood pressure, rapid heartbeat, and anxiety related to cardiovascular complaints.
- Supports heart function: taurine helps the heart muscle work more stably, especially with age-related changes.
- Helps with high blood pressure: used as part of a program to normalize blood pressure.
- Reduces rapid heartbeat: decreases the sensation of a “pounding heart” during excitement and stress.
- Reduces anxiety related to heart complaints: helps people whose rapid pulse or heartbeat causes worry.
- Suitable for long-term use: well tolerated in courses of 2 months or longer.
Magnesium L-threonate
Absorption ~75-80%Patented Magtein form developed by scientists at the Massachusetts Institute of Technology. The only form of magnesium that raises magnesium levels directly in brain tissue, not just in the blood. This affects memory, concentration, and thinking speed.
- Improves memory: increases magnesium levels in brain tissues, positively affecting information retention.
- Supports concentration: helps maintain focus longer during mental work.
- Slows brain “aging”: used to reduce cognitive changes.
- Relieves mental fatigue: reduces the “fuzzy head” feeling after prolonged cognitive load.
- Improves sleep quality: overnight brain recovery occurs more effectively.
Magnesium malate
Absorption ~75%Compound of magnesium with malic acid. Malate participates in cellular energy production. Helps with chronic fatigue, morning grogginess, and low stress resilience. Gentle on digestion.
- Restores strength in chronic fatigue: helps people who wake up exhausted and do not feel rested after sleep.
- Reduces muscle pain: eases aching muscle pains, especially in people with a sedentary lifestyle.
- Helps with low energy: suitable for overall decline in tone and performance.
- Supports post-workout recovery: speeds up return to normal after intense physical activity.
- Suitable for morning intake: can be taken in the morning without causing drowsiness.
Magnesium chelate
Absorption ~60-90%General name for forms where magnesium is bound to amino acids. Chelated forms include glycinate, lysinate, aspartate, taurate, and L-threonate. The body perceives such a complex as ordinary protein and absorbs it easily. A universal choice for any goal.
- Replenishes magnesium deficiency universally: suitable for any task — from sleep support to relieving cramps.
- Does not cause side effects: chelated forms do not irritate the stomach or cause intestinal discomfort.
- Combines with other supplements: can be taken together with most vitamin complexes.
- Suitable for long courses: can be taken for months without side effects.
- Maintains formula stability: properties do not degrade throughout the shelf life.
