What is the recommended dosage for Alpha-Lipoic Acid?

General: 300-600 mg/day; Skin Health: 300-600 mg/day (R-lipoic acid is more bioactive)

What are the side effects of Alpha-Lipoic Acid?

Potential side effects include: Nausea, Skin rash (rare), Hypoglycemia (may lower blood sugar).

What is alpha-lipoic acid and how may it support skin health?

Alpha-lipoic acid (ALA) is a sulfur-containing antioxidant that functions in both water and fat-soluble environments, making it effective throughout skin tissue. It regenerates other antioxidants including vitamins C and E. ALA has been studied for anti-aging skin effects including reduction of fine lines and improved skin texture.

What dosage of alpha-lipoic acid has been studied for skin benefits?

Skin-related studies have used 300–600 mg of alpha-lipoic acid per day orally, typically for 8–12 weeks. The R-enantiomer is considered the more biologically active form. Topical ALA studies have used 1–5% concentrations. Oral bioavailability is approximately 30% and is reduced by food.

What are the potential side effects of alpha-lipoic acid?

Common side effects include nausea, skin rash, and digestive discomfort. ALA may lower blood sugar and should be used cautiously with diabetes medications. A rare but serious side effect is insulin autoimmune syndrome, particularly reported in Japanese populations. Very high doses may have pro-oxidant effects.

About

Alpha-lipoic acid is a universal antioxidant soluble in both water and fat, capable of regenerating vitamins C and E and glutathione. A clinical study found oral ALA (300 mg/day for 12 weeks) reduced facial wrinkles, roughness, and improved skin texture in women.

How It Works

Universal antioxidant soluble in both water and fat; chelates metal ions and regenerates vitamins C and E and glutathione; may inhibit NF-kB activation and MMP expression in UV-exposed skin; supports mitochondrial energy production in aging fibroblasts.
