Lets get on topic with one of the most famous supplements to claim to be essential for Muscle growth. It’s a funny thing how all these body building principles seem to be a mandatory practice at one time, and than are busted or prophesised as not necessary later on. Eating small meals, post work out carbs, BCAA’s, Training more than an hour in the gym. They’ve all received their spotlight and appraisal at one point, and Glutamine supplementation was one of them. Glutamine is a non-essential Amino Acid, meaning we are capable of synthesising it ourselves in the body. However its lately becoming recognised as a “conditionally essential amino acid”; as its depletion rate is increased by stress, and certain individuals are required to increase their Glutamine pool through diet/supplements. Prolonged stress on the body, like through resistance training, is a potential way to deplete ones Glutamine levels in the body. Why would that matter? Well Glutamine reportedly is used to stimulate muscle growth, induce bodily repair, boost growth hormone, and increase ones immune system. Glutamine is stored in large measures in muscle tissue; proposing one doesn’t provide themselves with enough rest, the Glutamine stores will more rapidly deplete. If you’re looking to build muscle, than your obviously training hard…and when one is imposing such a physical strain on the body, they are also temporarily lowering their Immune System. Our Immune Cells feed off Glutamine, and with inadequate availability of Glutamine within the body, your periods of recovery will be directed towards immune restore and potentially reluctant on muscle recovery. Glutamine is also found to increase Glycogen Synthesis, which will assist cells to store glucose/energy, and utilise it for the next training session. Along with it’s capability to stimulate protein synthesis and Growth Hormone (putting our bodies in an Anabolic state); this can account for its “repairing” properties. Glutamine’s claim to promoting muscle growth, could be linked to its repair concept, and that one is more suitable to hit the gym sooner than someone who isn’t recovering as quick. Also glutamine’s “volumisation” attribute can contribute to muscle growth, as it’ll be taken into muscle cells, causing them to swell (Like Creatine).
It seems appropriate to acknowledge Glutamine as a valuable supplement for Athletes and Body Builders. However looking at a couple studies myself, I viewed contradicting outcomes of Glutamine supplementation; where some studies certify its acclaimed benefits, and other’s report no significant findings. Consider their are discrepancies between studies; like a lack of provided measurements, unrealistic time trials, varying forms of exercise (Endurance vs Strength training) and test subjects. It can be hard to respond with a direct answer on whether Glutamine is a necessity or not. Where do I stand on the matter? I don’t make a considerable effort to take Glutamine supplements. Meaning I don’t go out and buy a designated tub of it from Popeye’s or GNC. I’m aware that most protein powders will contain a large quantity of Glutamine, and I feel that if Glutamine was to ever be a concern to me, that I would be getting enough through that.
