Overview

What is Glutamine?

Glutamine from GN™ is only sourced from the most select manufacturers and is considered the best Glutamine available today. Glutamine is a semi-essential amino acid, meaning that whilst the body can produce its own glutamine this is not enough to fulfil the body's needs during times of stress, such as intense physical activity. Glutamine is naturally found in foods such as meat and fish, and can be found in particularly high levels in whey and casein protein. Stores can become particularly depleted in anyone undertaking intense exercise and therefore supplementation is recommended. Glutamine is currently receiving a huge amount of attention from the scientific community for it’s potential to aid muscular recovery and immune function.

How does Glutamine benefit performance?

Glutamine has been traditionally used by strength athletes and bodybuilders due to its reported role in protein synthesis and its ability to reduce recovery times (Legault 2015). Supplementation with Glutamine has been demonstrated to reduce muscle soreness and may also positively affect the action of branched chain amino acids. Glutamine has also been shown to play a role in muscle glycogen replenishment (Varnier 1995) which has caught the attention of both strength and endurance athletes alike.

How can Glutamine benefit immune function?

Intense or prolonged exercise can result in a drop in immune function, resulting in lower concentrations of white blood cells (lymphocytes and neutrophils) and decreased antioxidant action. Studies have shown that white blood cells will effectively utilise Glutamine as a fuel for energy (Newsholme 2001). Glutamine also plays a vital role in the production of glutathione (Cruzat 2014), a powerful antioxidant naturally synthesised by our bodies. Therefore, supplementation with Glutamine has been put forward as a way of enhancing this. Several studies have shown increases in both total white blood cell count and/or increases in antioxidant activity following supplementation with glutamine; from juvenile athletes (Koo 2014) and active adults (Song, 2015). Glutamine has also been shown to enhance immune function in older populations when combined with other amino acids and vitamins (Ohtani 2012). This has seen an increase in the use of glutamine as a dietary supplement, in particular amongst the endurance community.
