All Alpha-Lipoic Acid Supplements Compared
All 13 products sorted by cost per labelled serving (lowest first). Dose, certification, and pricing verified against NIH DSLD and manufacturer data.
Read the dose column before the price column. Servings in this category are not equivalent — they range from 100 to 600 mg per serving. A lower cost per day here can simply mean a smaller serving, so the cheapest row is not automatically the best value.

How We Rank Alpha-Lipoic Acid Supplements
Every product is evaluated on three criteria:
- Cost per day. Not cost per pill or cost per bottle — what it actually costs per day at the product's labelled serving. Where a category's servings differ in strength we flag it above the table, because cost per day is only comparable when the doses are.
- Third-party certification. USP Verified, NSF Certified for Sport, and ConsumerLab Approved indicate independent testing for purity, potency, and contaminants.
- Bioavailable form. We prioritize products using the specific chemical form shown to be most effective in published research.
Rankings are not influenced by affiliate commissions. We earn the same commission regardless of which product you choose. Read our full methodology.
