Trans Alanyl Glutamine (T.A.G.) 100% L-Glutamine Peptide - Rapid

In this review of Metabolic Nutrition's T.A.G. Trans Alanyl Glutamine, the bottom line is straightforward: this 400 g unflavored powder is best for athletes and busy professionals who want a high-dose, fast-absorbing glutamine supplement to speed muscle recovery. The reviewer found the decisive benefit to be the dipeptide form that bypasses typical digestion and raises serum amino acid levels quickly, providing noticeably faster post-workout recovery and supportive immune benefits compared with standard glutamine powders.

Key Features

• 10 g per scoop: Delivers a full 10 g dipeptide L-Alanyl L-Glutamine dose per serving to support muscle repair and protein synthesis after training.
• Dipeptide delivery: The Trans Alanyl Glutamine form is designed to absorb rapidly into the bloodstream rather than relying on slower digestion.
• Physician formulated: Created for men and women on the go, the formula is intended to be an easy-mixing powder suitable for pre, intra and post workout use.
• Immune support: Supplementing with glutamine may reduce infection rate and help maintain gut and immune health during heavy training.
• Clean ingredient profile: No calories, gluten, GMOs, lactose, soy, added sugars, fillers or artificial preservatives are included in the product.
• Unflavored option: The unflavored version mixes into drinks without added flavor, which helps when layering with other supplements.

Who It's For

The product suits athletes, competitors, and active adults who want a clinically relevant glutamine dose in a rapidly absorbed dipeptide format for faster recovery and reduced muscle soreness. It also fits professionals and students who train regularly and need a simple, mixable powder to support training recovery and immune resilience.

Those who prefer flavored supplements or who are prioritizing minimal serving sizes should look elsewhere, since this is a 10 g-per-scoop product in a 400 g tub (about 40 servings) and comes in unflavored or separate flavor options rather than single-serve sachets.
