Efectiv L-Glutamine + Vitamin C 300g, 4800mg Glutamine Per Scoop, 60 Servings

Efectiv Nutrition L-Glutamine + Vitamin C is a recovery and immune support powder combining glutamine with added Vitamin C. Each 5g serving delivers 4800mg L-Glutamine and 200mg Vitamin C at zero calories. The 300g tub provides 60 servings.

L-Glutamine is the most abundant amino acid in muscle and blood plasma, and the primary fuel source for intestinal epithelial cells and lymphocytes. During prolonged or high-intensity training, intramuscular glutamine depletion impairs both protein synthesis rates and gut barrier integrity. Supplemental glutamine replenishes these stores, supporting intestinal tight junction maintenance and immune cell activity in the post-exercise recovery window. Vitamin C at 200mg contributes to normal functioning of the immune system and normal collagen formation for the normal function of cartilage and bones, both EU-authorised health claims under Regulation 432/2012. The combination is logical: both glutamine and Vitamin C are depleted with high training volume, both support immune resilience in the recovery phase.

What separates this product from plain glutamine powder is the Vitamin C co-delivery. For athletes who take daily Vitamin C separately for immune support, this product removes one supplement from the stack while adding the combined immune-recovery benefit to a single serving. The dose of both glutamine and Vitamin C is meaningful rather than token.

Efectiv L-Glutamine + Vitamin C suits high-volume trainers concerned with immune suppression during intense blocks, endurance athletes managing gut integrity across multi-session training weeks, and anyone wanting a simple post-workout recovery supplement that addresses both gut and immune function. It is not a substitute for adequate total protein intake or whole-food vitamin C sources. Contains no major allergens.

300g tub delivers 60 full servings at just 24p per serve, making it one of the best-value glutamine supplements available.

Frequently Asked Questions

What does Efectiv L-Glutamine do and why is vitamin C added?

L-glutamine is the most abundant amino acid in muscle tissue and is used heavily during hard training and dieting. Topping up dietary glutamine helps maintain everyday intake. Vitamin C is added because it contributes to normal function of the immune system and helps protect cells from oxidative stress. Pairing the two means you cover recovery and immune support in one daily scoop.

When is the best time to take Efectiv L-Glutamine for recovery?

For recovery, take one scoop immediately after training. On rest days, take it first thing in the morning on an empty stomach. During heavier training blocks, you can split two servings across the day, one post-workout and one before bed, for a total of 9600mg. The zero-calorie profile means it fits any timing.

Is Efectiv L-Glutamine suitable for vegans and can I stack it with other supplements?

Yes to both. Efectiv L-Glutamine + Vitamin C is fully vegan-friendly and mixes easily into water, juice, protein shakes or any other liquid. It pairs well with whey protein, creatine, EAAs and pre-workouts, and there are no interaction concerns with other common sports supplements. The zero-calorie profile makes it suitable across any dietary approach.
