USA CALI L-Glutamine Powder – Pure Pharmaceutical-Grade Micronized L-Glutamine for Post-Workout Muscle Recovery, Gut & Immune Support*, Unflavored, 300g (10.6 oz), Made in USA

Description

Premium performance begins at the cellular level. USA CALI L-GLUTAMINE POWDER delivers pure, pharmaceutical-grade L-glutamine in a clean, unflavored format designed for discerning consumers who expect measurable quality, scientific credibility, and everyday versatility. Formulated for highly active lifestyles, this micronized powder dissolves easily and integrates seamlessly into water, smoothies, or pre/post-workout beverages—providing dependable amino acid support without fillers or artificial additives.

Ideal For:

• Athletes and strength trainers seeking support for post-workout recovery and muscle maintenance*

• Endurance and high-volume exercisers with elevated amino acid demands*

• Health-conscious professionals who prioritize clean, functional supplementation

• Individuals looking to support gut and immune system activity through nutrition*

L-Glutamine is the most abundant amino acid in blood plasma and skeletal muscle, and is considered “conditionally essential” during periods of physical stress, intense training, or caloric restriction. Skeletal muscle serves as the body’s primary glutamine reservoir, releasing it into circulation to support protein synthesis, cellular repair processes, and the metabolic needs of rapidly dividing cells—particularly in the gut lining and immune system. Research indicates that supplemental L-glutamine can help replenish circulating levels that may be depleted after strenuous exercise, thereby supporting lean muscle maintenance and recovery pathways.* Micronization enhances surface area for easier dissolution and reliable absorption in aqueous solutions.

Key Features:

• Pure, pharmaceutical-grade L-Glutamine with no fillers, binders, or artificial ingredients

• Micronized powder for fast mixing and flexible daily use

• Neutral taste suitable for stacking with other supplements

• Single-ingredient transparency for precise dosing control

Quality & Manufacturing:

Manufactured in a GMP-certified facility and third-party tested for purity, potency, and heavy metals. Packaged in the USA with rigorous quality controls that reflect USA CALI’s commitment to premium American standards. Made in USA.
