Glutamine is a conditionally necessary amino acid that is one of the 20 naturally occurring amino acids in dietary protein (being elevated to essential during periods of disease and muscle wasting typical of physical trauma). It’s available as an isolated amino acid and may also be found in high concentrations in dietary meats and eggs. Both whey and casein protein have significant amounts of it.
Because these cells prefer glutamine to glucose as a fuel source, glutamine is a particularly beneficial gut and immune system health component.
It is commonly advertised as a muscle builder, but it has not been proven to increase muscle growth in healthy people; only those who have suffered physical trauma, such as burns or muscular wounds (knife wounds), or who have disease states that cause muscle wasting, such as AIDS, have been shown to benefit from it. Glutamine, on the other hand, is helpful in these people in building muscle and reversing the ailment’s muscle loss.
How to Take
L-glutamine supplementation is usually dosed at 5 g or higher, with greater dosages being avoided owing to excessive ammonia in the blood. The lowest amount observed to raise ammonia levels in the blood was 0.75 g/kg, or around 51 g for a 150-pound person.
The ideal dosage of glutamine supplementation for growing muscle mass is unknown due to the relative inefficacy of glutamine supplementation for increasing muscle mass. The dosages listed above are adequate for intestinal health and preventing a possible relative glutamine deficit (Low protein consumption or vegetarianism are examples of this).
