Glutamine is one of the most important amino acids found in protein as it has a wide range of benefits. The most important benefits of glutamine supplementation are improved immune system function and better gut health. This means your body will better absorb the nutrients in the food that you eat - quite an important benefit we're sure you will agree.
Glutamine is also muscle-sparing so is a very useful amino acid to supplement when following a calorie deficit on a diet. Dosage guidelines for glutamine vary but around 10-30g per day is generally considered sufficient for those training hard and on a strict diet.
