Whether you're training hard, managing stress or looking to improve sleep, this is a smarter way to hit your daily magnesium needs.
Magnesium plays a key role in muscle contraction, electrolyte balance and energy metabolism, making it essential for performance and recovery. The bisglycinate form is bound to the amino acid glycine, helping it absorb more efficiently and reducing the risk of stomach discomfort.
