Fuel for the gut lining

Why your gut loves glutamine

L-glutamine is the most abundant amino acid in your body — and the preferred fuel for the fast-renewing cells that line your intestines. That makes it central to maintaining a healthy gut barrier ('intestinal integrity'). Under stress, illness or hard training your body can burn through its glutamine, so topping it up supports gut health, immunity and recovery.

How it works

Pure amino

One amino, mixes into anything

No flavour, no fillers but a touch of anti-caking — just pure L-glutamine that dissolves into water, juice or a smoothie without changing the taste.

— 1 tub = 98 g (30 servings)
