Clinical studies suggest that glutamine can support muscle recovery after strenuous exercise.
A new human study suggests that Sustamine is more efficient than free-form glutamine in delivering glutamine from the human gut to the blood.
Clinical studies suggest that glutamine can support muscle recovery after strenuous exercise. For this reason, glutamine supplements make up a large share of the bodybuilding supplements sector.
Eight men were assigned to consume one of four beverages containing free-form L-glutamine, hydrolyzed wheat protein, water, or Sustamine, a branded L-alanyl-L-glutamine ingredient from Kyowa Hakko USA (New York City).
While blood levels of glutamine increased with each supplementation form, Sustamine consumption provided a glutamine increase 224% that of free-form glutamine. Furthermore, Sustamine provided a glutamine absorption into the blood twice as long as when subjects consumed free-form glutamine or hydrolyzed wheat protein.
The study has been published in the journal Nutrition Research.
