What is Metagenics Magactive™ Muscle Magnesium Powder?

MagActive™ Muscle is a rasberry-flavoured magnesium powder designed for easy daily supplementation and versatile blending. It contains magnesium bisglycinate, a highly absorbable form of magnesium known for its enhanced bioavailability and gentle action on the digestive system.

This formulation helps support muscle relaxation and assists in reducing muscle cramps and spasms when dietary magnesium intake is inadequate. MagActive™ Muscle also includes activated vitamin B6 and vitamin B12, which support energy production, help maintain a healthy stress response, and contribute to normal muscle and nerve function.

Easy to mix and suitable for daily use, MagActive™ Muscle provides effective magnesium support for muscle health, energy, and overall wellbeing.

Each 7 g dose contains:

Magnesium (as Magnesium Bisglycinate) – A highly bioavailable and gentle form of magnesium that supports muscle relaxation, helps reduce muscle cramps and spasms, and contributes to normal muscle and nerve function.

Taurine – An amino acid that works synergistically with magnesium to support muscle function, nerve signalling, and cellular hydration, helping promote muscle relaxation and recovery.

Glutamine – Supports muscle recovery and overall metabolic health, particularly during periods of physical stress or exertion.

Acetyl-L-Carnitine – Supports cellular energy production by assisting the transport of fatty acids into mitochondria, helping maintain energy levels and support muscle performance.

Activated B Vitamins (B2, B3, B6, B12) – Essential for energy metabolism, nervous system support, and neurotransmitter function, helping maintain energy levels and a healthy stress response.

Vitamin C – Provides antioxidant support and contributes to normal energy metabolism and recovery.

Selenium and Chromium – Trace minerals that support antioxidant defences, metabolic health, and energy regulation.

ogether, these nutrients form a synergistic muscle-support complex that helps reduce muscle tension, support recovery, and maintain energy and nerve function.

“Magnesium bisglycinate is a highly absorbable form of magnesium because it is chelated to an amino acid, which allows the body to absorb and utilise it more efficiently. This helps deliver magnesium directly to muscles and nerves while remaining gentle on the digestive system and less likely to cause gastrointestinal discomfort. For this reason, magnesium bisglycinate is an excellent choice for supporting muscle relaxation, recovery, and maintaining healthy magnesium levels.”
