Product description GymSupps Magtein® Magnesium L-Threonate

GymSupps Magtein® Magnesium L-Threonate is a special, patented, and scientifically proven form of magnesium that is the only one proven to reach the brain. As a result, it works exactly where magnesium is most important for mental performance and peace of mind. It will help you improve your memory, concentration, sleep quality, and overall mental well-being. Ideal for anyone who wants more energy, a better mood, and to keep their brain in top condition.

3 main benefits:

  • Memory & Concentration
  • Sleep & Mood
  • Long-Term Brain Vitality

GymSupps Magtein® Magnesium L-Threonate at a Glance:

  • Patented Magtein® (Magnesium L-Threonate), exclusively licensed from Threotech, LLC
  • 1 capsule (666 mg) contains 48 mg of magnesium (12.8% RDA)
  • Measurable results within 2 weeks for sleep metrics.
  • Best taken in the evening (for sleep/peace of mind)

Vegetarian capsule:

Our capsules are made from plant-based hydroxypropyl methylcellulose, making them an ideal choice for vegans and vegetarians. Compared to animal-based capsules, they are also easier to digest and gentler on your digestive system, without any unnecessary animal-derived ingredients.

5 benefits:

  • Better deep and REM sleep
  • Faster mental “wake-up” in the morning
  • Support for memory and concentration
  • More daily energy and productivity
  • Patented, scientifically proven formula

When to Consider Using It and Who It’s Suitable For

GymSupps Magtein® is ideal for those who:

When:

  • Poor sleep quality, morning “brain fog,” difficulty studying or concentrating.
  • High mental stress, fatigue, heavy workload.
  • Need for long-term brain support (memory, focus, mood).
  • Evening workouts/competitions—better deep and REM sleep = better recovery.
  • Travel, disrupted routine, mild jet lag.

For whom:

  • Students, professionals, creative types, and “laptop” workers.
  • Parents who don’t get much sleep.
  • 50+ (long-term “brain” support).
  • Athletes: team and endurance sports, strength training.

Why Magtein® is better than other forms of magnesium

  • Exclusive license from Threotech, LLC —the only authentic Magtein® available worldwide, patented and distributed
  • It is unique in its ability to cross the blood-brain barrier (cerebral cortex) and increase magnesium levels directly in the brain. This sets it apart from conventional magnesium supplements, which replenish magnesium in the blood but have no evidence of a comparable increase in the brain.

vs. the competition

  1. Exclusively licensed Magtein® from Threotech, LLC
  1. Unverified or generic forms of magnesium
  1. Clinically proven effects on the brain and sleep
  1. Lack of scientific evidence
  1. Transparent ingredients, vegan capsules, Magtein® only
  1. Unclear ingredients, fillers, gelatin capsules

Recommended dosage of Magtein® Magnesium L-Threonate:

  • 3 capsules. Do not exceed the recommended daily dose.

Tento produkt tedy u mě opravdu pomáhá se spánkem,už po užívání 3 den . Já beru hodinu před spaním 2 tablety + 1 tabletu Melatoninu od firmy extension. Když se vzbudím,zase rychle usnu. Je třeba dodržovat při probuzení : nedívejte se do světla,třeba na telefon,to vám způsobí,že mozek si myslí,že je ráno a zbytek melatoninu se vám odplaví. Doporučuji jen slabší červené světlo,pokud je to nutné.
