Bulk Glutamine powder is one of the most popular products in the Pure Series range. Glutamine powder is 100% L Glutamine, which is a conditionally essential amino acid. This means at certain times, this amino acid is needed from the diet, as the body cannot synthesis enough. One of these occasions is after you work out – training causes muscle glutamine levels to deplete to a point where the amino acid becomes conditionally essential. Consuming L Glutamine Powder will provide your body with a rich source of Glutamine that will help to restore muscle glutamine levels. Best consumed post-workout or intra-workout.
