Description

Natural Factors L-Lysine provides relief from the herpes simplex virus (HSV), helping reduce the recurrence, severity, and healing time of cold sores. As one of the nine essential amino acids that the body relies on to manufacture protein, L-lysine has important roles in the synthesis of collagen, tissue repair, and the production of hormones and enzymes. This makes L-lysine an important nutrient for maintaining a healthy immune system, especially when combined with an adequate intake of vitamin C.

 

L-lysine is considered “essential” because the body cannot manufacture it and it must be obtained through dietary sources. People with HSV can include L-lysine as part of their nutritional strategy to help keep the virus in check and prevent flare-ups of uncomfortable lesions around the mouth and genitals.

 

Natural Factors L-Lysine is a pharmaceutical-grade, free-form amino acid, meaning it is more effective than the form obtained directly from food. Each two-capsule serving provides 1000 mg of L-lysine to be taken three times per day for the most effective absorption. This is a great choice for anyone who is prone to HSV flare-ups, as well as vegetarians and other people who may not get sufficient L-lysine through their diet.

 

  • Provides relief from cold sores

  • L-lysine helps reduce the recurrence of herpes simplex virus (HSV) infection

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.
