Is magnesium glycinate good for sport?
Answer
Magnesium carries authorised claims for normal muscle function, protein synthesis, electrolyte balance and reduced tiredness at adequate intake. There is no sport specific claim and no form changes that.
Key takeaways
- What can it claim?
- Normal muscle function, normal protein synthesis, electrolyte balance and the reduction of tiredness and fatigue, at 15 percent NRV or above.
- Is there a sport claim?
- No. The claims apply to everyone at adequate intake and there is no athlete adjustment.
- Does glycinate change anything?
- Not the claims. It is the gentlest common form at a full daily serving, which matters for adherence.
What is actually claimable
Magnesium has one of the fuller claim sets of any mineral, all available at a serving providing at least 15 percent of the 375mg reference value. Normal muscle function. Normal protein synthesis. Reduction of tiredness and fatigue. Electrolyte balance. Normal energy yielding metabolism. Normal nervous system and psychological function.
None is a performance claim and none is adjusted for training. Futuro Labs Magnesium Glycinate provides 300mg elemental at 80 percent NRV, so all of them apply comfortably.
Why the form is still the right one
Not because it changes the claims, which attach to the mineral. Because bisglycinate is chelated to glycine and is generally the most comfortable of the common forms at a full serving.
For a player taking a serving daily from July to April, tolerability decides whether the product is still being taken in November, and that matters more than any absorption argument between the well absorbed forms.
