Bisglycinate-form magnesium for high absorption and gentle GI tolerance
Supplement Needs Magnesium Bisglycinate 120 Caps is a high-bioavailability magnesium capsule built for trainees who want a clean chelated magnesium without the GI side effects associated with cheaper magnesium oxide forms. Each serving delivers 151.2mg of elemental magnesium from 1375mg of magnesium bisglycinate chelate. The bottle provides multiple weeks of daily use.
Magnesium bisglycinate is magnesium bound to two glycine molecules, a chelated form that increases absorption and reduces the laxative effect that magnesium oxide is known for. The 151.2mg elemental dose (40% 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 is the smallest amino acid and contributes mildly to the calming effect that pre-bed magnesium routines often target.
What separates Supplement Needs Bisglycinate from a standard magnesium oxide capsule is the form. Cheap magnesium oxide products run at high mg counts on the label but with poor absorption rates and well-known gut-irritation effects. The bisglycinate form trades higher per-serving cost for genuinely better absorption and tolerability - the Supplement Needs brand has built its reputation on this kind of evidence-based form selection.
Magnesium Bisglycinate suits trainees running pre-bed magnesium for recovery and sleep support, athletes with GI sensitivity who don't tolerate magnesium oxide well, and lifters managing the magnesium loss that comes with sweating in high-volume training. Not the right pick for trainees who prefer powder formats or who need higher elemental doses across multiple-form blends.
Alternative: Efectiv Nutrition Magnesium Bisglycinate Blend 90 Caps delivers 100mg elemental magnesium from three forms (bisglycinate, malate, citrate) for trainees who want a multi-form approach.
