Brand: Nutrex Research

What is L-glutamine and do I need glutamine supplementation?

Glutamine is an amino acid that actually delivers results and helps your body in many ways. According to Wikipedia (The Free Encyclopedia on the Internet) it claims that L-glutamine has a variety of biochemical functions and many uses. Glutamine has been studied extensively over the past 10-15 years and has been shown to be useful in the treatment of serious illnesses, injuries, trauma, burns, cancer, and its treatment-related side effects as well as in wound healing for postoperative patients.

However, L-glutamine is mostly marketed as a supplement used for muscle growth, and muscle recovery and to aid in protein synthesis in weight training, weight lifting, bodybuilding, and other sports which require endurance. Upon extreme physical activity (like bodybuilding and weightlifting), your body draws large amounts of L-glutamine from the most abundant source you have – muscles. Therefore, a lack of this important amino acid can lead to muscle breakdown (aka catabolism). However, Nutrex Research Glutamine Drive is here to help!

By consuming a balanced diet of fresh veggies, lean meats, fish, and dairy, you’ll ensure you’re getting a good dose of natural L-glutamine from those foods to help with muscle recovery. If you’re looking for an added boost, protein shakes (since they contain at least 3 g of glutamine), and separate L-glutamine powders (like Nutrex Research Glutamine Drive ) are widely available. Supplementing with L-glutamine can help maintain muscle integrity, support immune function, and aid in muscle recovery—all the things needed to build a better body.

Brief product description & key product features

Description

Nutrex Research Glutamine Drive delivers 5g of pure L-glutamine per serving to rapidly replenish glutamine levels in the body after strenuous workouts in order to support faster post-workout recovery. Therefore, the main purpose of this product is to reduce muscle breakdown caused by training, poor diet, or stress as quickly as possible.

Glutamine Drive is designed as a post-workout recovery drink. However, it also makes sense to consume it before training to ensure that your body doesn’t run short during your workout. Even if it is taken before the training you have to be fully aware that glutamine will not have the effect of improving your athletic performance during the training like most pre-workout supplements do. You can’t expect L-glutamine will boost your energy, and promote enhanced endurance and mental focus so you can go longer and harder with your workouts.

Downsides of Nutrex Research Glutamine Drive

Given that it is such a simple product – with only one ingredient, it is difficult to find any flaws or illogicalities. We have only two recommendations:

This product comes flavorless. It would be good if there was a variant with at least one flavor – for those who consume glutamine exclusively with water and don’t mix it with other beverages or other flavored supplements.
Nutrex Research Glutamine Drive is not fermented (or, better to say produced by fermentation). Without going into too much detail we’ll just say that fermented L-Glutamine provides an easier form of glutamine for the body to absorb.
The container is entirely too tall, making it difficult to get your hand in enough to scoop. This is especially true if you have bigger hands and when it’s halfway done.
The scoop handle is too short.

Suggested use (method of application)

Mix 1 scoop with 6-10 oz of water or your favorite sports beverage and consume 1 to 2 times daily. For best results, take 2 scoops per day. On workout days, take 1 serving 45 to 60 minutes before your workout and 1 serving after.

Do I need Nutrex Research Glutamine Drive if my whey or casein protein already contains a sufficient dose of L-glutamine?

No, in this case, you don’t need a separate (standalone) L-glutamine supplement. Many brands of meal-replacement products and protein supplements contain glutamine, making separate supplementation totally unnecessary. Every better whey protein already contains glutamine (and all other necessary amino acids) in a sufficient dose. For example, 100% Whey Gold Standard from Optimum Nutrition (the best whey protein on the market) contains 4 g of glutamine per serving. This satisfies all your daily needs for L-glutamine. Or even better, Kaged Muscle Kasein Protein Powder contains even 5.0 grams of glutamine & glutamic acid per serving (1 scoop or 35.6 g). However, if you consume 1 protein shake a day you can still take an additional 5 g of L-glutamine from a separate glutamine supplement.

Best supplements to pair with

This flavorless and odorless formula stacks and mixes easily with other supplements including BCAA, EAA, protein, creatine, pre-workout, and post-workout drink. Keep in mind that whey protein and casein already contain some amount of L-glutamine. The same can be true also for some pre-workout, and post-workout formulas.

If you decide to buy this product the safest option is to make a purchase directly from the company’s official website to ensure original products are delivered to you.

Testimonials

Go for it!
Maximizing glutamine’s effects on your body requires you to use your head first. If you’re not training hard, your body probably can supply you with all you need. But if you’re the type who punishes your body regularly, taking Nutrex Research Glutamine Drive the right way could help you keep performing at an elite level.
Marko Mitrović,

Yes, but only if you really need it!
There’s nothing wrong with taking Glutamine Drive, or any other glutamine supplement for that matte. It’s cheap, and it’s probably good for your gut health. There’s some evidence that folks on low protein diets can experience illness because their gut gets low on glutamine, affecting its immune system. But if you’re adding spoonfuls of the stuff to your shakes, there’s no need. If you’re consuming between one and two grams of protein per kilogram of body weight (especially if a share of that protein comes from whey and animal sources), then your body and muscles probably have all the glutamine it needs. My advice? Just eat protein, bro.
