High-absorption magnesium bisglycinate for muscle, sleep and energy
DY Nutrition Magnesium Bisglycinate 90 Capsules is a high-bioavailability magnesium supplement from the Dorian Yates Nutrition brand, built for trainees who want clean chelated magnesium without the GI side effects associated with cheaper oxide forms. Each serving delivers 1250mg of magnesium bisglycinate compound providing 250mg of elemental magnesium. The bottle provides 45 days of daily use.
Magnesium bisglycinate is magnesium bound to two glycine molecules - a chelated form that increases absorption versus magnesium oxide and reduces the laxative effect oxide is known for. The 250mg elemental dose (67% NRV) contributes to normal muscle function, normal protein synthesis, normal energy-yielding metabolism, normal psychological function and a reduction of tiredness and fatigue (EFSA-authorised under Regulation 432/2012). Glycine itself contributes mildly to the calming pre-bed effect that magnesium routines often target.
What separates DY Bisglycinate from a standard oxide capsule is the form. Cheap oxide products run higher mg counts on the label but with poor absorption and well-known gut-irritation effects. The bisglycinate form trades higher per-serving cost for genuinely better absorption and tolerability. The 250mg elemental dose is also higher than most peer bisglycinate products, which typically sit at 100-150mg elemental per serving.
Magnesium Bisglycinate suits trainees running pre-bed magnesium for recovery and sleep support, athletes with GI sensitivity who don't tolerate oxide well, lifters managing magnesium loss from high-volume training, and anyone running structured training programmes following the Dorian Yates methodology. Not for trainees who specifically want multi-form magnesium blends.
Multi-form alternative: Efectiv Nutrition Magnesium Bisglycinate Blend 90 Caps delivers 100mg elemental from three forms (bisglycinate, malate, citrate) for trainees who want a multi-pathway approach over a single-form higher dose.
