120 Caps

4000mg GLUTAMINE per 4 Capsules

Applied Nutrition's Glutamine Veggie Caps are formulated for rapid disintegration and maximum absorption. Glutamine is the most abundant amino acid in the body, comprising more than 60% of the free amino acid pool in skeletal muscle and greater than 20% of total circulating amino acids. Applied Nutrition's Glutamine Veggie Caps are made from the highest quality pharmaceutical grade glutamine available on the market. Each Serving provides 4000mg (4g) of pure L-Glutamine.

Each serving provides 4000mg glutamine, 4 Capsules serving. This gives a clear nutritional profile for anyone managing their daily intake carefully.

Each pack contains 30 servings. Use after training to support recovery. Daily consistency matters more than exact timing.

The main reasons people choose Glutamine 4K are intra-workout support (useful around hard sessions), light to sip (easy during training), easy to keep around (simple to use often). These practical benefits set it apart from other options in the same category.

Glutamine 4K is manufactured by Applied Nutrition. No common allergens. Produced in a facility that handles milk, soy, eggs, fish, celery, cereals containing gluten and products thereof. Full ingredient and allergen details are listed on this page and on the product packaging.

Frequently Asked Questions

How much GLUTAMINE is in each serving of Glutamine 4K?

Each 4 Capsules of Glutamine 4K declares 4000mg of glutamine on the label. That works out to 120 Caps per pack. The full label is published on this product page so you can cross-check before stacking it with anything else.

When should I take Glutamine 4K?

Glutamine 4K is best taken post-training or before bed. Consistent use over time tends to do more than precise timing, so build it into a daily routine and let the habit do the work. Pair it with a balanced diet and a structured training plan, since supplements deliver against an existing stack, not on their own.

Is Glutamine 4K third-party tested?

Glutamine 4K is manufactured by Applied Nutrition in their UK facility. Many Applied Nutrition ranges carry Informed Sport batch testing for banned substances, so check the on-pack badge if Informed Sport status matters for your federation. The full ingredient breakdown and allergen disclosure is published on this product page, so you can review what is on the label before adding it to your stack.
