Improved immunity
I’ve noticed a significant improvement in my immunity. Previously, I caught a common cold every year, but since taking glutamine, I’ve remained healthy for six months. It’s quite remarkable for a supplement.

Cures common cold
I initially used it to combat weakened immunity during weight loss, but I've found it most effective in curing a common cold before it worsens. Since starting, I’ve felt stable and consider it essential.

Boosted immunity
Optimum Glutamine is my go-to drink each morning. I've been using it for over 15 years, and it’s a fantastic energy booster. I rarely catch a common cold or suffer from flu episodes, and it helps keep my 73-year-old body trim with lower body fat.

Cold prevention
This drink is the best for improving immunity! I take it every morning to prevent the common cold. It’s essential for anyone training, as glutamine is crucial for health.

Avoided common cold
I mix it with protein after training. If I forget to take it, I often catch a common cold, so it’s beneficial for recovery and overall health. It also remained effective after being stored for over a year.
