Sustamine™ L-Alanyl-L-Glutamine

Product Benefit Statement

Sustamine™ health benefits include more rapid absorption of water and electrolytes in your intestines, the promotion of the synthesis of glycogen and muscle protein, as well as protection of protein once it’s formed. Sustamine can improve the uptake of nutrients in your GI tract.
In research trials, it was shown that the Sustamine L-Alanyl-L-Glutamine was more effective at improving water and electrolyte uptake than L-Glutamine by itself. L-Alanine’s main role in the body is to renew glycogen stores.
Rehydration with Sustamine also appears to maintain skill performance and visual reaction time to a greater extent than water only.


Product Description

Sustamine™ L-Alanyl-L-Glutamine, is a stable dipeptide derivative of L-Alanine and L-Glutamine. Awarded the best Ingredient for Beverages: Kyowa Hakko, Sustamine. The amino acids L-alanine and L-glutamine are easily absorbed to benefit muscles. The dipeptide Sustamine is water-soluble, GRAS, and also taste- and odor-free, making it perfect for rehydration and recovery drinks.

_ Sustamine enhances electrolyte and water absorption in the intestines. * 2, 4
_ Sustamine stimulates glycogen synthesis.* 5
_ Sustamine inhibits muscle protein breakdown.* 6, 7
_ Sustamine promotes the synthesis of muscle protein.* 1, 7
_ Sustamine helps protect the integrity of the gastrointestinal trace, contributing to better nutrient absorption.* 6, 8
_ Sustamine helps support the immune system.* 9, 10
_ Sustamine research suggests that supplementation conveys a significant ergogenic benefit by increasing time to exhaustion under conditions of mild dehydration.
