Doctor Life / 01

Magtein® Pro

Made for your daily routine.

Three capsules provide 1,500 mg of Magtein® and 700 mg of ATA Mg®. These are the weights of the complete compounds, not elemental magnesium. Magtein® contributes 116 mg of magnesium and ATA Mg® contributes 50 mg, totaling 166 mg—44% NRV. The formula combines two clearly identified magnesium forms.

Magnesium supports normal nervous system and psychological function, energy metabolism, and muscle function, and helps reduce tiredness. Vitamin C also supports nervous system and psychological function and energy metabolism, and helps protect cells from oxidative stress. Vitamin D supports muscle and immune function and healthy bones.

The label highlights ingredient purity, protective-atmosphere packaging that limits oxygen exposure, and selected branded ingredients. Magtein® is licensed by ThreoTech LLC; ATA Mg® is a trademark of Synapharm SA. Pullulan capsules provide a measured serving without mixing powder.

Magtein® Pro

Why choose Magtein®?

Elemental magnesium can come from different compounds, so both the amount and form matter. Magtein® Pro combines two identified branded forms studied in relation to the nervous system. The formula makes those sources and their contributions clear, without relying on elemental magnesium weight alone.

Magtein® Pro

What does research say about Magtein® Pro?

Randomized human trials of Magtein® have examined cognition, memory, and sleep. ATA Mg® research includes preclinical work on magnesium availability, tissue distribution, and neurophysiological measures. A 2026 preclinical publication compared magnesium acetyl taurate with L-threonate and examined their combination. Animal findings do not establish clinical benefits, and these studies do not test the finished Magtein® Pro formula.

Science & sources

Understand the formula.

Magtein® Pro combines two branded magnesium forms developed through research focused on the nervous system. The strongest clinical evidence concerns Magtein®, magnesium L-threonate studied in randomized trials of cognition and sleep. ATA Mg® adds a complementary research direction involving tissue distribution and neurophysiology.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01The effects of magnesium L-threonate (Magtein®) on cognitive performance and sleep quality in adults: a randomised, double-blind, placebo-controlled trial

Adrian L. Lopresti, Stephen J. Smith

Frontiers in Nutrition (2026), 12, 1729164. DOI: 10.3389/fnut.2025.1729164; PMID: 41601871.

In a six-week randomized, double-blind study, 100 adults took 2 g of Magtein® daily, or a placebo. The Magtein® group showed greater improvement in overall cognitive performance, particularly working and episodic memory, along with faster reaction times. The study examines the clinical potential of the branded magnesium L-threonate also used in Magtein® Pro.

02Magnesium-L-threonate improves sleep quality and daytime functioning in adults with self-reported sleep problems: A randomized controlled trial

Heather A. Hausenblas, Tarah Lynch, Stephanie Hooper, Aahana Shrestha, Doug Rosendale, Jennifer Gu

Sleep Medicine: X (2024), 8, 100121. DOI: 10.1016/j.sleepx.2024.100121; PMID: 39252819.

In a randomized, double-blind study, 80 adults ages 35–55 took 1 g of magnesium L-threonate daily for 21 days. Compared with placebo, researchers observed favorable differences in selected sleep measures recorded by an Oura ring, as well as morning function, energy, productivity, mood, and mental alertness. This adds direct human data on Magtein®.

03Enhanced Neurophysiological Benefits of Magnesium-Acetyl-Taurate Over Magnesium-L-Threonate: A Comparative pre-clinical Study on Bioavailability, Synaptic Plasticity and Cognitive Functions

Aakash Kumar, Sidharth Mehan, Sumedha Gupta, Ghanshyam Das Gupta, Rajaram Samant, Manoj Tongra

NeuroMolecular Medicine (2026), 28(1), 25. DOI: 10.1007/s12017-026-08929-6; PMID: 42084749.

This preclinical study compared magnesium L-threonate, magnesium acetyl taurate, and their combination. Researchers assessed magnesium levels in plasma, cerebrospinal fluid, and brain tissue, along with synaptic plasticity and animal behavior. Acetyl taurate and the combination showed favorable results across several measures. The study is relevant to the two magnesium compound types in Magtein® Pro, but it does not establish effects in humans.

FAQ / Magtein® Pro

Good questions. Clear answers.

Talk to us ↗

Why combine two magnesium forms?

Each has a distinct formulation and research background. Magtein® has been studied in human cognition and sleep trials. ATA Mg® magnesium acetyl taurate has been examined preclinically for availability and nervous tissue distribution. Magtein® Pro brings both into one serving; the combination is not established as superior to either alone.

Why do 1,500 mg of Magtein® and 700 mg of ATA Mg® provide 166 mg of magnesium?

The larger figures are the weights of the complete compounds. Magtein® provides 116 mg of elemental magnesium and ATA Mg® provides 50 mg, totaling 166 mg—44% NRV. Compare both elemental magnesium and its source when reviewing products.

Is 166 mg of magnesium too little compared with 300–400 mg products?

It provides 44% NRV. The formula combines 2,200 mg of two branded magnesium compounds rather than aiming for the highest elemental magnesium amount. Whether it suits your needs depends on your diet, other supplements, and individual circumstances.

Is there research behind the focus on the brain?

Magtein® has randomized human trials examining memory, cognition, reaction time, and sleep. Magnesium acetyl taurate research on brain tissue distribution and neurophysiological measures is preclinical. These are different levels of evidence, and neither establishes the clinical effects of the finished combination.

How is Magtein® Pro different from Doctor Life Magtein® powder?

The tropical-flavored powder provides 2,083 mg of Magtein® as a single magnesium form. Magtein® Pro combines 1,500 mg of Magtein® with 700 mg of ATA Mg®, plus vitamins C and D3, in capsules. Choose based on the formulation and format that fit your needs.

Why include vitamins C and D3?

Vitamin C supports normal nervous system and psychological function, energy metabolism, and the reduction of tiredness. Vitamin D supports muscle and immune function and healthy bones. They add established nutrient functions to the magnesium formula.

Should I take all three capsules together, and must I take them in the evening?

The label specifies 3 capsules daily with a meal or 200 mL of water. It does not require a particular time or divided schedule. Choose a consistent routine and do not increase the capsule count yourself.
