Buying Guide

Choose the active form when needed

R-lipoic acid offers the biologically active isomer preferred in some studies; consider stabilized R-ALA formulations for targeted nerve or metabolic support

Check milligrams per serving

Common therapeutic doses are around 300–600 mg per serving; compare total mg per capsule and servings per bottle to estimate daily dosing

Evaluate capsule type and additives

Vegetarian/vegan capsules and products labeled non‑GMO or gluten‑free can reduce exposure to common allergens and align with dietary preferences

Consider combined antioxidant formulas

Some ALA supplements include complementary extracts or absorption enhancers like grape seed extract or black pepper extract (piperine) to support antioxidant synergy and bioavailability

Balance dose with value

Compare mg per serving and total capsule count across brands to estimate cost per dose and identify budget options under a preferred price range
