NOW Foods Pure L-Glutamine Powder is currently one of the bestselling glutamine supplements on the market, with over 500 highly rated reviews on Amazon. But with so many companies now producing pure L-Glutamine, why should you buy this version from NOW Foods?

In this review we’ll be taking a closer look at what you’re getting from the 90 servings you can typically find in one of their 1 lb tubs. This includes the health benefits, background research into the company, and how the recommended dosage differs based on gender and bodyweight.

We’ll also consider whether it’s safe to combine NOW Foods L-Glutamine with their BCAA (Branch Chain Amino Acid) powder, and how it can be included in supplement stacks for endurance and strength.

Does the powdered form of L-Glutamine really represents the best value for money?

NOW Foods Pure L-Glutamine Ingredients

With just one ingredient, NOW Foods L-glutamine is about as simple as it gets. Powder form is a big advantage too, as the lack of gelatin capsules means it’s suitable for vegetarians and vegans.

Each tub is manufactured in a GMP facility to maintain high quality standards, packaged inside a recyclable tub that’s available in two sizes; 1.1 lbs and 2.2 lbs. The powder also contains no wheat, gluten, soy, milk, egg, fish, or tree nut ingredients.

So how does this compare to other L-glutamine supplements? Is NOW Foods an affordable option?

Most companies now follow the same 5 gram serving size recommendation. Studies have found higher doses of 20-30 g/day to be effective for normalizing plasma concentration in critically ill patients, but 5 g is standard for a post-workout recovery dose.

Bodybuilders will typically take 2-3 of these 5 gram servings throughout the day, with 1 dose in the morning, 1 dose post-workout, and 1 at night before sleep. Although glutamine is perfectly safe, it’s a good idea not to go much above 10 to 15 grams per day.

Cost comparison

NOW Foods also supply their L-glutamine in capsule form, but with 1 g per serving. If you’re looking to maintain the minimum dose of 5 g per day, the capsules will cost you more than twice as much as the powder.

In the long-term, your best option is to buy a tub of their glutamine powder. At time of writing, the 1 gram capsules cost around $0.11 each, while the 1 pound tub was $0.19 for 5 grams. The larger 2 pound tub was $0.20 per serving.

What results can I expect?

There’s a lot of reviews on Amazon and numerous fitness websites saying that glutamine supplementation helps with muscle recovery. Recovery is fairly subject, and for many people this may well be true. Unfortunately clinical studies proving this are hard to come by.

What has been scientifically proven is glutamine’s ability to boost your immune system and improve intestinal health for conditions such as ‘leaky gut syndrome’.

‘Leaky Gut Syndrome’ (LGS) is a condition associated with starvation, injury, infection, chemotherapy, and other types of stress. Many studies consider glutamine the most important nutrient for healing LGS, as it supports recovery of intestinal barrier function.
