Optimum Nutrition L-Glutamine Muscle Recovery Powder

on glutamine 1

Optimum Nutrition L-Glutamine Powder comes in several sizes: 150g, 3006, 600g and 1000g of unflavored powder containing nothing but the purest form of L-glutamine.

Serving size is 1 rounded teaspoon (5g of powder) to be taken with 8 oz of water or some beverage or to be used as directed by licensed nutritionist or physician.

Note: ON L-Glutamin doesn't come with a scoop - personally, I use very accurate scale (up to 0.1g of accuracy, for less than 200g total weight) to measure my supplements. Such small scale is cheap and can last for a long time.

Since this is unflavored powder, some users are almost thrilled when they consume it mixed with the plain water.

Personally, I use it in my Post Workout Meal (PWM) shakes, stacked with fast carbs, whey protein, BCAAs and creatine monohydrate.

When I am on a strict diet, I use it before workouts too, stacked with some BCAAs and EAAs, regardless if I go to the gym, on a track or for power-walk on a home treadmill.

on glutamine caps

Optimum Nutrition L-Glutamine Capsules come is several sizes, too: 60, 120 and 240 capsules. Each capsule contain 1000mg (1 gram) of pure L-glutamine.

Note: capsules come in the bottles with '1000 CAPS' text written - this means that each capsule contain 1000mg of l-glutamin and exact amount (number) of capsules is written with slightly smaller text.

These capsules are designed for rapid disintegration and maximum absorption of L-glutamine after use.

Price of the L-glutamine per gram is higher when compared with the L-glutamine in powdered form, but some people find it more easy to consume L-glutamine in this form.

It is recommended to consume 1-2 capsules between meals, 30-45 minutes before workouts and/or immediately after workouts or to be used as directed by licensed nutritionist or physician.

Personally, I don't like pills, tablets and capsules and I don't like empty wallet, so I don't use ON Glutamine in capsules.

However, some athletes stack the glutamine capsules with BCAAs capsules and consume throughout the day, helping the body stay in anabolic state, even when on low calorie diet.


on glutamine mLong Story Short: Optimum Nutrition L-Glutamine can help athlete to improve recovery and regeneration after workouts and can help boost immune system.

Scientific studies confirming these statements are not fully conclusive, but ...

IMHO, I add it mostly to my PWM shakes and I feel better when I take it, especially when I am on a strict diet. When I am not on a low-calorie diet (maintenance diet or bulking diet), the effects of taking glutamine, at least for me, are not as evident.

Note: going on a diet, taking supplements, working out hard etc - only after consulting with your physician, or licensed nutritionist and trainer.
