Magnesium L-threonate
The patented Magtein formula, created by a research team at the Massachusetts Institute of Technology (MIT).

Calcium + Magnesium
A balanced mineral duo (usually in a 2:1 ratio). Magnesium is essential for proper calcium absorption and calcitonin synthesis. Without it, calcium doesn't strengthen bone structure and may instead deposit on blood vessel walls and in the kidneys. Best suited for women over 40 and athletes.
Bone density
magnesium directs calcium straight into the bone trabeculae, helping protect against osteoporosis.
Age protection
a basic complex for supporting the female skeleton during hormonal changes.
Stronger tooth enamel
taking them together supports dentin mineralization and healthy teeth.
Safe for blood vessels
helps prevent calcification and hardening of the large arteries.

Magnesium oxide
An inorganic compound with a high share of pure magnesium but a very low ability to be absorbed into the bloodstream. It isn't suitable for correcting a systemic tissue deficiency. In medicine, it's valued for its strong antacid effect and for stimulating peristalsis when a gentle GI tract cleanse is needed.
One-time laxative effect
a reliable option for occasional constipation when quick bowel relief is needed.
Relieves heartburn
quickly neutralizes excess stomach acid.
Affordable price
the most budget-friendly raw material, often used in simple pharmacy products.
Not for regular use
due to minimal absorption, it doesn't resolve the cell-level magnesium deficiency.

External use: Epsom Salt (Magnesium Sulfate)
Magnesium sulfate is practically never prescribed for internal use. But as Epsom salt, it's indispensable for relaxing baths and foot spa treatments. Dissolved in warm water, the mineral has a local relaxing effect on skeletal muscles and helps ease nervous tension before bed.
Fast muscle relaxation
a warm salt bath instantly releases tension in the neck, lower back and hips after exercise.
Lighter legs
foot baths relieve swelling and the feeling of "aching legs" after a workday.
Skin care
makes skin smooth, speeds up cell-cleansing processes and reduces flaking.
Deep sleep
an evening bath an hour before rest slows the heart rate and prepares the nervous system for sleep.

External use: Magnesium Oil (Transdermal Magnesium Chloride)
A highly concentrated magnesium chloride solution in spray or lotion form. Its texture resembles a dry oil, although it contains no fats. The advantage of the transdermal method is absorption directly through the skin pores, bypassing the digestive tract. It's an ideal option for those who get GI discomfort from capsules.
Targeted spasm relief
applied directly to a tight muscle, it instantly relieves calf cramps and neck spasms.
Zero strain on the GI tract
bypasses the stomach, eliminating the risk of heartburn, nausea and a laxative effect.
Evening relaxation

Fast recovery

The Hidden Benefits of Magnesium: What Else This Mineral Can Do
Magnesium is often seen purely as a calming aid before bed, but its effect at the cellular level is far broader: it restores neuromuscular fibers, supports blood sugar balance and protects tissues from premature wear.
Neural Balance and Recovery
Physiology and muscle tone
- Control of night sweats. By helping regulate the sympathetic nervous system, the mineral stabilizes thermoregulation during the deep phases of sleep.
- A natural solution for constipation. Citrate formulas retain moisture in the intestines, helping restore regular bowel movements without dependence on synthetic laxatives.
- Eased PMS symptoms. Magnesium combined with pyridoxine relaxes the smooth muscle of the uterus, reducing lower abdominal cramping and mood swings.
Metabolism and disease prevention
- Fewer sugar and chocolate cravings. Natural cocoa is a record holder for magnesium content. A sharp urge to eat chocolate often points to a hidden mineral deficiency.
- Protection against oxalate kidney stones. Magnesium citrate competes with calcium for oxalates in the GI tract, binding them and removing them naturally without crystallization in the urinary tract.
- Improved insulin sensitivity. This trace mineral activates enzymes that process glucose, which is especially important for prediabetes and metabolic syndrome.
Additional therapeutic effects
- Tinnitus relief. Clinical studies confirm a reduction in the perceived intensity of ringing and noise in the ears once magnesium levels are restored.
- Support for bronchial hyperreactivity. Helps relax the smooth muscle fibers of the bronchial tree.
- Fibromyalgia therapy. Magnesium malate is one of the top recommendations for relieving pain and morning muscle stiffness.
Please note: chelated forms (bisglycinate, taurate, malate) and citrate offer the greatest benefit. Choose your dosage according to the manufacturer's instructions or a specialist's recommendations.
