The Claim

In endurance-trained individuals, magnesium-creatine supplementation is associated with increased intracellular water, which may reflect greater muscular creatine retention due to creatine's osmotic properties and could be linked to enhanced cellular hydration and potential stimulation of protein synthesis.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

If you're an endurance athlete, taking magnesium-creatine might help your muscles hold more water, which could mean better creatine absorption and possibly help your muscles grow or recover faster.

What the research says

1 study
  1. Study: Magnesium-creatine supplementation effects on body water.

    The study looked at people taking magnesium-creatine and found their muscle cells held more water, which matches the idea that this supplement helps muscles retain more creatine and stay hydrated, possibly helping build muscle.
