Description
L-Glutamine is an amino acid that can be found throughout the body, especially in the brain, gastrointestinal tract, muscles, and liver cells. After periods of physical stress, L-glutamine helps support a healthy immune system and digestive system, and helps restore depleted glutamine levels in the blood and muscle. This assists in repairing muscle tissue after intense exercise and can accelerate post-exercise recovery time. Additionally, L-glutamine improves energy levels and brain function, and helps maintain the integrity of the intestinal barrier.
Although L-glutamine can be made by the body and is found in many high-protein foods, it is most effective when taken as a free-form amino acid. Natural Factors L-Glutamine Free Form Amino Acid is natural muscle food contained within vegetarian capsules. This is especially beneficial to vegetarians, vegans, or people following restricted diets who may not get enough L-glutamine through food sources alone. Each capsule delivers 1000 mg of L-glutamine to be taken multiple times per day for the most effective absorption and use by the muscles. It is well-tolerated and safe when used as directed.

Frequently Asked Questions
What is Natural Factors, and is it a trustworthy supplement brand?
Natural Factors is a Canadian-owned supplement manufacturer founded in 1948 and headquartered in Coquitlam, British Columbia. One of North America's largest supplement makers, it operates over 1,000 acres of certified organic farmland in BC's Okanagan Valley and manufactures in-house at Health Canada-licensed, FDA-inspected facilities. Every product is third-party tested through ISURA for over 800 contaminants including pesticides and heavy metals. Natural Factors is also B Corp certified, meeting rigorous environmental and social standards.
What is Natural Factors and is it a reliable Canadian supplement brand?
Natural Factors is one of Canada's largest supplement manufacturers, founded in 1955 by Jack and Rona Katz in British Columbia and still 100% Canadian family-owned. The company controls every production stage from raw material sourcing to finished product. Its facility holds TGA certification from Australia's Therapeutic Goods Administration, one of the world's strictest supplement manufacturing standards. All products are ISURA certified — independently tested for 800+ contaminants including pesticides and heavy metals — and Natural Factors conducts four rounds of product testing, double the industry average of two.
What sets Natural Factors apart from other supplement brands?
Natural Factors' most distinctive quality is vertical integration: the company grows its own raw herbs on 1,000+ acres of certified organic farmland in BC's Okanagan Valley, then processes and manufactures in-house. Most supplement brands source raw materials from external suppliers with no direct agricultural control. Natural Factors also uses ISURA third-party testing, a Canadian standard that screens for over 800 contaminants, well beyond typical heavy-metal panels. B Corp certification further reflects a documented commitment to environmental and social accountability, not just a marketing claim.
What makes Natural Factors different from other Canadian supplement manufacturers?
Natural Factors holds TGA certification from Australia's Therapeutic Goods Administration — one of the world's most rigorous pharmaceutical manufacturing standards, rarely earned by Canadian brands and far exceeding most North American certification requirements. Its ISURA testing program screens every product for 800+ contaminants, and it conducts four rounds of quality testing per product versus the industry standard of two. The company also operates its own farm in the Okanagan Valley for select botanical ingredients — a level of vertical integration uncommon among supplement manufacturers — and has been family-owned for over 70 years.
