Metabolic Nutrition L-Glutamine is a single-ingredient amino acid powder: 5,000mg of L-glutamine per scoop, unflavored, in 100g, 300g, 500g and 1000g tubs. Glutamine is the most abundant free amino acid in muscle, and athletes use it to support recovery from hard training.† The brand says there are no fillers, binders, preservatives or artificial ingredients, so it mixes into water, a shake or your intra-workout drink without changing the taste much. It is made without gluten, dairy, egg, peanut, soy, shellfish, wheat or yeast, in a facility that processes those allergens.

About Metabolic Nutrition
Metabolic Nutrition is a sports nutrition brand known for its clean single-ingredient amino acids and its ultra cold-pressed line. The brand says it makes its supplements in its own manufacturing facility rather than through outside contract manufacturers. Its amino acid powders keep things simple: one ingredient, one scoop, no flavoring. That makes them easy to stack with whatever pre-workout, protein or EAA you already use.
L-Glutamine 5,000mg
Glutamine is a conditionally essential amino acid. Your body makes it, but stores can drop during periods of intense or high-volume training. It plays a role in muscle protein balance, gut lining health and immune cell function, which is why it has been studied in athletes for decades.† A 5g serving sits in the range most commonly used in sports nutrition. Results on muscle growth alone are mixed, so think of glutamine as recovery and gut support rather than a muscle builder.†
Frequently Asked Questions
-
When should I take L-Glutamine?
Metabolic Nutrition suggests taking it right after workouts or during periods when you need extra recovery support. Some people split it, with one scoop post-workout and one before bed on heavy training days. Timing matters less than taking it consistently. Stay within the label's daily directions.† -
Does it have a taste?
It's unflavored, and glutamine powder is close to neutral with a faint sweetness. Most people mix it into a protein shake, an EAA or BCAA drink, or plain water. It dissolves best in room-temperature liquid with a quick stir or shake. It won't change the flavor of most drinks. -
Can I stack it with creatine or protein?
Yes. Glutamine is commonly stacked with creatine, whey and EAAs, and there are no known conflicts among them. Because this is a single ingredient, you can control the dose separately from the rest of your stack. Check that your other products don't already contain a large glutamine dose so you know your total intake.† -
Which size should I get?
The 100g tub is a low-commitment way to try it, while the 500g and 1000g tubs suit daily users. At 5g per scoop, the 1000g size covers roughly 200 servings. Glutamine powder keeps well when the lid stays tight and it's stored somewhere cool and dry. Ask our staff if you want help sizing it to your training schedule.
