Key Health Benefits

  1. Supports Muscle Health and Recovery: As a key amino acid involved in protein synthesis, L-Glutamine supports muscle growth and recovery, especially after intense physical exercise. It may help to decrease muscle soreness and improve recovery time.

  2. Promotes Gastrointestinal Health: Glutamine is an important energy source for intestinal cells. By supporting these cells, this supplement can contribute to the overall health of the gastrointestinal tract and maintain the barrier that prevents bacteria or toxins from leaking into the rest of the body.

  3. Supports Intestinal Mucosa Health: Glutamine promotes the health of the intestinal mucosa, which is the lining of the gastrointestinal tract. This is critical in nutrient absorption and preventing harmful substances from entering the bloodstream. Supports healing of leaky gut.

  4. Supports the Production of Glutathione: Glutamine is necessary for the production of glutathione, a powerful antioxidant produced in the liver that helps neutralize harmful free radicals, peroxides, and heavy metals in the body.

  5. Assists in Glycogen Replenishment: After exercise or stress, the body depletes its glycogen stores. L-Glutamine can assist in the process of reloading these stores, providing the body with the energy it needs for recovery and function.

Premier Muscle and Gastrointestinal Tract Support*
  • A key amino acid supporting protein synthesis* 
  • Supports the gastrointestinal tract while promoting intestinal mucosa health*
  • Supports muscle recovery and glycogen reloading*
  • Important for the production of glutathione, a key liver nutrient*


Premier Glutamine delivers L-glutamine (free form) that is derived from beneficial bacteria (not synthetically made). Glutamine is a key amino acid that supports muscle and gastrointestinal tract health while also promoting intestinal mucosa health.

The intestines are supported by healthy glutamine levels. Glutamine serves as a critical source of energy for intestinal cells, which help to maintain the barrier between the intestines and the rest of the body.* This barrier prevents bacteria or toxins from leaking from the intestines into the rest of the body.* Additionally, glutamine is necessary in the production of glutathione, a key liver nutrient which prevents damage to important cellular components such as free radicals, peroxides, and heavy metals.*

Glutamine, the most abundant amino acid in the body and one of the few which can cross the blood-brain barrier, plays an important role in biological functions including protein synthesis.* Research has shown that glutamine supports the preservation of muscle mass so it may be helpful in post-exercise recovery.* During catabolic states or stress, as in post-exercise, it supports muscle recovery and glycogen reloading.*
