What is Glutamine?

THE PROTEIN WORKS™ Glutamine is an Amino Acid produced within the liver and skeletal muscle. Making up 61% of our muscle, it is the most abundant Amino Acid in the body, helping us to process protein, giving more opportunity to make those all-important gains. Considered a conditionally essential amino acid, it becomes essential during times of muscle wastage or illness..

How does Glutamine work?

Although our bodies produce Glutamine naturally, we often don't maintain optimal levels while exercising, that's where the bad boys from TPW™ come in! Adding Glutamine Powder to your diet helps contribute towards a reduction in muscle depletion during high-intensity exercises and gives our bodies a helping hand in protein metabolism, ready for the next round of body busting workouts.

What does Glutamine Do?

Glutamine plays a key role in protein metabolism, which is essentially the breakdown of proteins in our muscles, allowing all TPW™ protein packed shakes and bakes to be absorbed quicker and easier into our muscles. During exercise, protein is key for not only helping to repair muscle fibres, but also energy production. Time is precious, so the quicker protein can reach your muscles, the better.

Glutamine also has protective roles against the damage caused by prolonged exercise. Intense exercise lasting longer than 60 mins depletes intestinal stores of glutamine, this leads to increased permeability and stomach discomfort. Supplementing glutamine could restore the gut which contributes towards the protection of your immune and digestive system, giving them extra personal security from infections and disease.

Why buy Glutamine?

Nobody likes to wake up the following day from a hard workout with aches and pains! Glutamine can help support recovery by repairing the damaging effect of an unaccustomed bout of exercise by ensuring your muscles process and receive protein quickly. Meaning that your muscles can repair and grow, without feeling stiff in the morning. Win, Win!

When is the best time to take Glutamine?

The best time to take Glutamine is around 30 minutes prior to physical activity, this ensures that your body and blood can process the Amino Acid and send it directly to your muscles. If you have a TPW™ Pre-Workout Shake you could also add Glutamine for added oomph. The added glutamine will allow your body to use its food stores for energy production, rather than using muscle, meaning that you can burn calories without worrying you’re going to lose that hard earned muscle mass.

Who should take Glutamine?

You should buy Glutamine if you love to workout or take part in physical activity on a regular basis. Perfect for any diet, but more prominently those who want to burn that dreaded belly fat, and keep their gains. Not only can Glutamine help you in the gym but it can also help improve your overall health and well being. Available in a variety of flavours specifically engineered in-house by THE PROTEIN WORKS™, you will be spoilt for choice.

Orange Burst Glutamine 1kg
After reading a few reviews I decided on purchasing the Orange Burst in a 1kg bag. Orange tastes really good, glad I purchased 1kg! Cut my recovery time within 1 week. I mix it with 300ml of ice cold water for a refreshing drink. Glutamine is great for aiding recovery, healing your GI tract and overall health. Great Product thanks TPW!

We recommend you read the ingredients and nutritionals on the label to better understand exactly what you are buying. We can assure you that our products are 100% pure. At TPW™, we are committed to transparency and openness in all our products and that is why we provide a Product Profile on Glutamine which gives a complete overview of the product's background including our approval, location of manufacture and money back guarantee applicability.
