Thorne Alpha-Lipoic Acid

Antioxidants typically work in only one environment — either in fat-soluble tissues (like cell membranes) or water-soluble fluids (like blood plasma). Alpha-lipoic acid is different. It's both fat- and water-soluble, which means it can function in virtually every tissue in the body — inside cells, in blood, in nerve tissue, in the brain.

For endurance athletes generating high levels of oxidative stress across multiple tissue types simultaneously, that reach matters. ALA doesn't just mop up free radicals in one place — it works everywhere.

And it doesn't stop there. ALA also recycles other antioxidants (glutathione, vitamin C, and vitamin E) extending their effective life and amplifying the body's entire antioxidant defense network.

Fat and Water Soluble – Because ALA operates in both fat-soluble and water-soluble environments, it provides antioxidant protection in cell membranes, blood plasma, brain tissue, and peripheral nerves simultaneously. A single compound covering the entire spectrum — from the mitochondrial membrane where energy is produced to the neural pathways that carry motor signals — makes it one of the most broadly useful antioxidants available for athletes under high oxidative load.

Glutathione Regeneration – ALA helps restore depleted glutathione — the body's master antioxidant and primary liver detox molecule — back to its active form. It also regenerates vitamins C and E, effectively extending the working life of the antioxidants you're already consuming. Research in well-trained athletes shows ALA supplementation during intensive training periods reduces markers of muscle damage and inflammation and supports faster recovery between sessions.

Metabolic and Nerve Health – ALA is a cofactor in mitochondrial energy metabolism, directly participating in the process that converts glucose into ATP. It has decades of clinical use supporting healthy glucose metabolism, insulin sensitivity, and peripheral nerve health — including well-documented reduction of nerve-related discomfort in neuropathy.

Thorne's formula delivers 300mg of ALA per capsule — a dose well within the effective range established in clinical research (300–600mg daily), with flexible dosing allowing athletes to run 600–900mg daily under practitioner guidance for enhanced support.

How to Use Thorne Alpha-Lipoic Acid

Dosage: Take 1 capsule two to three times daily with food, or as recommended by your healthcare practitioner. Spreading doses through the day maintains consistent ALA availability in tissues.
