FAQs
What does glutamine do?
Glutamine is an amino acid found naturally in your body. It plays a role in protein synthesis and may support immune and gut function. Supplementing can help maintain levels during intense training or periods of dietary restriction.
How should I take a glutamine supplement?
Most powders recommend around 5 g per serving mixed into water or shakes. Capsules offer smaller doses that can be taken with meals. Follow the directions on the label and adjust according to your needs.
Can I mix glutamine with protein shakes or BCAAs?
Yes. Glutamine is often added to protein or amino acid drinks. It dissolves easily and has little taste when unflavoured, so it blends well with other supplements.
Is glutamine a replacement for protein intake?
No. Glutamine supplements provide a single amino acid and are intended to complement a balanced diet. They shouldn’t replace complete protein sources or meals.
