• R-Alpha-Lipoic Acid is the biologically active, more bioavailable isomer. Each capsule provides 100 mg to support strong antioxidant protection in both water- and fat-soluble parts of the cell.
• This versatile antioxidant regenerates other antioxidants (like vitamins C and E) and boosts glutathione, enhancing cellular defense.
• Supports healthy aging and metabolism. Clinical data suggest improved insulin sensitivity and nerve function, with potential relief from neuropathy symptoms.
• 60 vegetarian capsules provide a convenient daily dose of 100 mg R-Alpha-Lipoic Acid. For best absorption, take on an empty stomach (30 minutes before or 2 hours after meals).

Description
Lipoic acid (LA), also referred to as alpha-lipoic acid (ALA), is a naturally occurring and necessary biological factor. Although initially classified as a vitamin, LA is not a true vitamin because it can be synthesized in the body. It is a vitamin-like substance with functions similar to the B vitamins. There are two isomers for LA, designated R (R-LA) and S (S-LA), which are mirror images of each other chemically. R-LA is the preferred form, as it is naturally synthesized in the body and more efficiently absorbed, requiring lower doses and yielding higher concentrations than S-LA. R-LA is the biologically active form of lipoic acid and participates as an essential cofactor in biological processes.
LA is one of the most potent and diverse naturally occurring antioxidants. It has several unique abilities: the ability to work as an antioxidant in both water- and lipid-soluble parts of the cell and cell membrane; the ability to regenerate other antioxidants; and the ability to remain active once it neutralizes free radicals. LA has clearly earned its title of being the universal, super antioxidant. LA has long been known to be useful in promoting health and managing chronic diseases, including nervous system disorders and diabetes. It is also becoming known for its ability to boost metabolism, aid in weight loss, and protect against the effects of aging.

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.
