Description

Natural Factors L-Tyrosine is a free-form amino acid that helps decrease cognitive fatigue resulting from physically stressful situations, such as extended wakefulness, exposure to cold, and excessive noise.

 

L-tyrosine is a non-essential amino acid and a fundamental component of proteins with numerous critical roles throughout the body. L-tyrosine is also required for the synthesis of several important compounds, including the hormone thyroxine, the pigment melanin, and the neurotransmitters dopamine, norepinephrine, and epinephrine, which play important roles in the body’s stress response.

 

Although the body can synthesize L-tyrosine from the amino acid phenylalanine, consuming it directly contributes to the maintenance of healthy levels. L-tyrosine is found in various protein-rich foods such as meat, fish, dairy, and certain plant-based foods. However, L-tyrosine is most effective when taken in its free form. Supplementing with L-tyrosine can be beneficial for people at risk of fatigue or overstimulation from stress, including individuals with irregular work and sleep schedules, athletes involved in strenuous training, and professionals working in chaotic or fast-paced environments.

 

This supplement is available in convenient vegetarian capsules that are non-GMO, suitable for vegans, and third-party certified for purity and potency. Each capsule contains 500 mg of L-tyrosine, providing a total daily dose of 3000 mg.

Frequently Asked Questions

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.
