PER4M Advanced Magnesium is a high-absorption formula designed to support muscle function, recovery and nervous system balance. Each daily serving delivers 300mg of elemental magnesium from magnesium bisglycinate — a premium, bioavailable form that’s easy on digestion and built for results you can feel. 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. It’s also known for its calming effect, supporting relaxation and quality sleep — ideal for active people who need to switch off and recharge.

Per4m Nutrition

If you’re pushing your body daily or feeling the effects of fatigue, PER4M Advanced Magnesium delivers clean, effective support to help you perform, recover and reset.
