About Protocol for Life Balance - Magtein® (formerly ProtoSorb™ Magnesium)
Protocol for Life Balance Magtein® delivers magnesium L-threonate, a form of magnesium specifically studied for its ability to cross the blood-brain barrier and support magnesium levels in the brain. Unlike common magnesium salts, this patented compound may help maintain cognitive function, memory, and neurological health. It's particularly well-suited for adults focused on brain health and mental clarity.
Why It's Worth Considering: Magtein® is a clinically researched, patented form of magnesium L-threonate — the same compound used in foundational neuroscience studies — offered here at a straightforward dose without unnecessary fillers.

Frequently Taken Together
Frequently Asked Questions
-
Magnesium glycinate (bisglycinate chelate) is widely considered the best form for sleep, anxiety, and muscle cramps due to high bioavailability and zero laxative effect. Citrate is better for constipation. Threonate may be superior for cognitive function as it crosses the blood-brain barrier. Oxide has only 4-5% absorption and is primarily a laxative.
-
No. Unlike magnesium citrate and oxide which draw water into the intestines (osmotic laxative effect), glycinate is chelated and absorbed through a different pathway that does not affect GI motility. It is the most GI-friendly magnesium form available.
-
Take 1-2 hours before bed for sleep benefits. The glycine component promotes relaxation via GABA receptor activity. For general supplementation, any time works — glycinate does not require food for absorption.
-
Standard blood tests (serum magnesium) are unreliable — only 1% of body magnesium is in the blood. Signs include muscle cramps, poor sleep, anxiety, eye twitches, chocolate cravings, and headaches. Since 80%+ of adults are suboptimal, supplementation is generally recommended.
-
Yes, but separate from zinc, calcium, and iron by 2+ hours (they compete for absorption). Magnesium pairs well with Vitamin D3, K2, and B6 taken together.
-
The RDA is 310-420mg/day for adults. Most functional medicine practitioners recommend 400-600mg for therapeutic benefit. Start with the product's recommended dose and adjust based on response.
