Bulk Supplements Pure L-Glutamine is currently one of the bestselling glutamine supplements on Amazon, with thousands of highly rated customer reviews. But how does the quality compare to competing products that often cost twice as much per serving, such as those from Optimum Nutrition and MuscleTech?
As one of the most abundant amino acids in the body, glutamine is critical to muscle repair after endurance or resistance training, as a key component in protein synthesis. But how many mg of glutamine should you take each day, and is it the same for all body types?
In this review we’ll provide a guide to the health benefits of Bulk Supplements L-Glutamine, the best time of day to take it, recommended dosage, and whether you need to ‘cycle’ or go through a ‘loading phase’ as you do with some creatines.
We’ll also make important comparisons between two other top rated glutamine supplements; Optimum Nutrition Glutamine and MuscleTech Platinum Glutamine. This is to help you create the perfect supplement for your fitness goals and budget.
Bulk Supplements L-Glutamine Ingredients
Bulk Supplements specialize in providing single-ingredient supplements in bulk, at affordable prices. That’s exactly what they’ve done with L-glutamine, where you can buy sacks of up to 25 kg on Amazon.
Even following their maximum recommended dose of 3 g per day, this should last around 8,000 days, which is the equivalent to nearly 22 years. While this offers excellent value for money ($0.01 per serving at time of review), it’s probably not the most practical option.
For a more realistic 1 kg tub, which should still last just under a year at 3g/day, you’re looking at closer to $0.03 per serving. That’s considerably cheaper than every other glutamine supplement we’ve reviewed, including MusclePharm Glutamine and MuscleTech Platinum Glutamine.
Bulk Supplements L-Glutamine powder is free from soy, sugar, dairy, yeast, gluten, and additives. Because it’s in powder form rather than gelatin capsules, it’s also suitable for vegetarians and vegans.
What results can you expect?
As a non-essential amino acid, L-glutamine is taken to reduce muscle catabolism post-workout, boost your immune system, and promote a healthy digestive system. Improvements in muscle recovery have also been experienced when taken post-workout.
‘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.

What sizes are available?
With a serving size of 1 g and a product weight of 1000 g, each bag provides you with approximately 1000 servings. Bulk Supplements also sell their glutamine in various forms, ranging from powder to vegetarian capsules, in sizes from 100 grams up to 25 kg.
If you were to supplement with 1 gram per day, their glutamine powder sizes are enough to last you:
- 100 grams: 14 weeks
- 500 grams:70 weeks (17 ½ months)
- 1 kg: 140 weeks (35 months)
- 25 kg: 67 years+
However, most glutamine supplements have a much larger serving size of 5-10 grams per serving. If you were to take the Bulk Supplements product in this kind of quantity, twice per day, then you would need at least the 500 gram bag to get you through the first 6 weeks.
Save money with Amazon
If you’re looking to save money on your monthly supplement order, you might want to consider the Amazon Subscribe & Save program.
Subscribe & Save allows you to unlock savings of up to 15% on a wide range of sports nutrition products, including Bulk Supplements Pure L-Glutamine (selected sizes only).
You can save 5% with a subscription to 1 product, or save the full 15% by subscribing to 5 products, provided they’re all delivered to the same address. The delivery schedule can be set from monthly, up to once every 6 months.
Although 5 products might sound a lot, if you already supplement with a protein powder, multivitamin, creatine, BCAA, and glutamine, the savings can soon add up. But it’s best to order before you run out of your current supplements, because Amazon set the day of the month each order is sent (usually around the 14th).
Who are Bulk Supplements?
Bulk Supplements products are perfect if you need complete control over the level of ingredients going into your pre-workout, post-workout, and intra-workout nutrition. That’s because they supply over 200 nutritional supplement ingredients to hundreds of thousands of customers and manufacturers.
Whereas companies like MuscleTech create complex combinations of ingredients designed to offer an all-in-one ‘off the shelf’ solution, Bulk Supplements allows you to create your own custom nutrition.
It’s an idea that’s proven incredibly popular, with many of their supplements achieving thousands of positive reviews on Amazon alone. Some of the best include their micronized creatine monohydrate, whey protein powder isolate, and BCAAs.
To find out more about their current product line, we recommend taking a look at our Bulk Supplements buying guide. This includes a summary of the health benefits, which sizes and flavors are available, and dosages for the main ingredients.
