What is Glutamine?

Glutamine is the most abundant amino acid in your body. Synthesised internally, not from the food we eat, its not considered an essential amino acid. However, in special circumstances, such as illness or injury, our body's utilization will outpace the demands. For example, in times of sickness the substantial amount of physiological stress causes a negative imbalance between the building and breakdown of muscle. As such Glutamine supplementation should be considered. Before you question your need to use this conditionally essential amino acid you should know glutamine has more tricks up its sleeve.

What does Glutamine Do?

Glutamine performs a number of roles including the support of muscle growth and fulling the cells of the immune and digestive system. Without it, muscle wouldn't regrow, our health would deteriorate and our digestive system would not be able to absorb the food we eat. Now you understand why it's the most abundant amino acid!

When we exercise we place a significant amount of strain on the mentioned processes. Depleting our limited stores of glutamine increases our risk of under recovery. Poor recovery increases our risk of infection, meaning less training and a longer time to achieve our goal.

When is the best time to take Glutamine?

There are a number of way to supplement glutamine, it all depends on circumstance and purpose.

In the instance of supporting muscular recovery, research has found 0.1-0.3g per kg of body weight capable of reducing delayed onset muscle soreness. In other words, if you weigh 80kg, taking 10g of glutamine post workout will negate the muscular ache we feel after pushing ourselves in the gym.

In endurance athletes, taking 5g post workout will significantly reduce the occurrence of illness. For gut health benefits, supplementing 0.25-0.90g per kg of body weight 1 hour before running can reduce the occurrence of gut discomfort associated with endurance exercise. This supplement is no one-trick-pony, you just have to use it intelligently.

Who should take Glutamine?

If you’re looking to ensure you’ve got plenty of this amino acid in your system then supplementing via Glutamine Powder is a great option. Available in a variety of flavours specifically engineered in house by THE PROTEIN WORKS™, you will be spoilt for choice.

Love this
I started taking glutamin when I started training several years back- I stopped and then one time I had an ulcerated flare up which stops me training really annoying but I took glutamin and I'm sold that glutamin can suppress my uc symptoms along with the repairing process after a heavy training session. I love glutamin.

Great in Berry
I have recently got some of this in the Berry Blitz flavour as well as the other Apple and Orange flavours which i have not opened yet, i find the flavouring to have been improved with this product as well as the BCAAs over the years which makes this much nicer to consume on a regular daily basis, this is also one of the easiest mixing forms of glutamine that i have tried. For Free Protein Use My Referral Code: JM15339 I notice that L-Glutamine works awesome when i consume it at a dose of around 5-10 grams per day to improve my muscle recovery by reducing post workout muscle soreness, this is also a great supplement to promote an increase in natural human growth hormone levels which is another reason i tend to include it in my nutritional intake year round.
