Transparent Labs Magnesium Bisglycinate

Transparent Labs Magnesium Bisglycinate addresses three critical gaps for endurance athletes: muscle cramping, sleep quality, and recovery between hard sessions.

Transparent Labs Magnesium Bisglycinate delivers 300mg of highly absorbable chelated magnesium that supports muscle function, deep sleep, and nervous system calm without digestive issues.

The Form You Absorb – Magnesium bisglycinate is chelated—bonded to glycine, an amino acid that enhances absorption and eliminates the laxative effect common with other magnesium forms like citrate or oxide. This means you get the magnesium you need without the digestive disruption that derails training. Research shows bisglycinate offers superior bioavailability compared to cheaper forms.

Three Benefits You'll Feel – First, muscle function and cramp prevention. Magnesium regulates muscle contraction and relaxation, helping prevent the cramps that plague endurance athletes during long efforts. Second, sleep quality. The glycine component promotes GABA activity, the neurotransmitter that tells your nervous system to calm down—critical for athletes struggling to wind down after hard training. Third, recovery support. Magnesium is essential for ATP production and protein synthesis, the processes your body uses to rebuild stronger after training stress.

Why Athletes Run Low 

Nearly half of Americans don't meet magnesium needs through diet, and athletes lose 20-30% more through increased urinary excretion during training—not through sweat as commonly believed. Research suggests athletes need 10-20% above the RDA (400-420mg for men, 310-320mg for women). Signs you're low: persistent muscle cramps, difficulty falling asleep despite fatigue, slow recovery between sessions, and general tension that won't release even with proper rest protocols.

How to Use Magnesium Bisglycinate

Take 3 capsules daily (300mg total). Most athletes benefit from evening dosing 30-60 minutes before bed to support both muscle relaxation and sleep quality. Can be taken with or without food, though some prefer with meals to maximize absorption.
