Glutamine FAQ & Buying Guide
What does glutamine actually do?
Glutamine fuels rapidly-dividing cells — muscle during recovery, the cells lining your gut, and immune cells. Athletes use it to support recovery and gut health, especially during calorie deficits or high training volume when natural levels dip.
When should I take glutamine?
Timing is flexible: post-workout and before bed are the most common. Typical serving is 5 g, mixed easily into water, a shake, or BCAAs — it's flavourless.
Is glutamine the same as BCAAs or EAAs?
No — glutamine is a single conditionally-essential amino acid, while BCAA/EAA products are blends of the essential aminos that drive muscle protein synthesis. They complement each other rather than overlap.
Is glutamine good for gut health?
Glutamine is the primary fuel for the cells lining the small intestine, which is why it appears in many gut-repair protocols alongside probiotics.
Does Fuel Supplements ship glutamine across Canada?
Yes — Canada-wide from our BC warehouses, with same-day pickup in Port Coquitlam.
