Magnesium bisglycinate is often considered superior to other magnesium forms due to its enhanced bioavailability and gentler digestive profile.

Better absorption: The glycine amino acids protect the magnesium from binding with other compounds in the digestive tract that could interfere with absorption. This chelated form allows more magnesium to actually reach your bloodstream compared to forms like magnesium oxide.

Digestive tolerance: Unlike magnesium oxide or sulfate, which commonly cause loose stools or diarrhea, bisglycinate is much less likely to have laxative effects. The glycine chelation prevents the magnesium from drawing excess water into the intestines.

Additional benefits: Glycine itself has calming properties and may support sleep quality, making this form particularly useful for evening supplementation or stress management.

The key advantage of magnesium L-threonate is its potent ability to effectively cross the blood-brain barrier and raise magnesium levels in the brain, much more so than other forms. This makes Magnesium L-threonate particularly beneficial for cognitive function.

Brain-specific delivery: Magnesium L-threonate was shown to raise the magnesium levels in the brain and neurons effectively unlike most other magnesium forms only cross the blood-brain barrier at a normal low rate.

Cognitive support: Research suggests it may help with memory, focus, and overall brain function. Intraneuronal magnesium has been scientifically demonstrated to support neuroplasticity and mental focus, and improve memory in the aging brain.

Sleep quality: Recent studies show Magnesium L-threonate improved sleep quality, especially deep/REM sleep stages, improved mood, energy, alertness, and daily activity and productivity.

Zinc is an essential mineral for health, required for vital enzymatic activity, primary metabolic pathways and maintaining cell structure. It plays a pivotal role in normal growth, sexual development, wound healing, immune health, sense of taste, skin health and other vital functions.

OptiZinc® is a zinc mono-L-methionine sulfate, expertly designed as a 1:1 complex of zinc and methionine.

OptiZinc® zinc mono-L-methionine chelate ingredient has superior absorption, retention and antioxidant properties over other forms of zinc. This unique combination of pioneering properties could offer enhanced health benefits, as these depend on the amount of zinc absorbed and utilized by the body.
