Top 5 Alpha Lipoic Acid Supplements in 2025
Last Updated: January 20, 2025
In the last few months, we've received dozens of emails asking us to review the supplement alpha-lipoic acid, which has recently taken the internet by storm due to the number of people with neuropathy and diabetes who have been sharing online. So, over the past few weeks, we have researched and put together this article for you, in which we list our top 5 Alpha Lipoic Acid supplements available in the U.S.


Before we look at our top 5 list, let's answer a few of your most common questions around the populare alpha lipoic acid supplement.
What is alpha-lipoic acid? Alpha-lipoic acid (or lipoic acid) assists in converting glucose into energy (see What It Is). A healthy body naturally produces enough alpha-lipoic acid but supplementation may help in certain situations.
What does alpha-lipoic acid do? Alpha-lipoic acid supplements may modestly improve insulin sensitivity and blood sugar control, as well as reduce symptoms of peripheral neuropathy in people with type 2 diabetes. It may also modestly increase weight and fat loss when combined with a low-calorie diet (see What It Does).
What's the right dose of alpha-lipoic acid? The typical dose used in treating diabetes, peripheral neuropathy associated with diabetes, and cardiac autonomic neuropathy is 200 to 400 mg, taken 3 times daily (for a total daily dose ranging from 600 mg to 1,200 mg). For weight loss, 100 mg alpha-lipoic acid (taken three times per day with meals), along with a reduced-calorie diet, has shown some benefit. For use as a general antioxidant, a lower dose (20 to 50 mg daily) is commonly recommended (although there is no evidence this offers any health benefit). You may be able to halve the dose when using the R-isomer-only form (see What to Consider When Using).
What are the side-effects of alpha-lipoic acid? Side effects of alpha lipoic acid such as skin rash and nausea have been reported. Alpha lipoic acid may also contribute to acid reflux, as it is an acid. It may also cause a strong urine odor. Because alpha-lipoic acid may help control blood sugar in diabetics, adjustments may be needed to anti-diabetic medication when using alpha-lipoic acid. Alpha-lipoic acid may interfere with thyroid function, medication and diagnostic tests. Although rare, alpha lipoic acid may cause insulin autoimmunity (see Concerns and Cautions).

Overview
After reviewing the top 20 alpha lipoic acid supplements, our favorite by far was the Meo Nutrition alpha lipoic acid supplement.
It boasts a clean and potent formula containing 650 mg of alpha lipoic acid without any additional ingredients. However, many competitors offer the same formula, so what set Meo's supplement apart was their 60-day satisfaction guarantee, their quick shipping (we received it the next day), and their responsive customer service when tested.
In addition to its pure and potent ingredients, this berberine supplement is also incredibly well-priced, coming in at just $0.56 per capsule—or as low as $0.49 per capsule when purchased in bulk.
Finally, they offer a fair, 60-day, risk-free, money-back guarantee. Most companies won’t do this, which demonstrates how much they stand behind their products. Overall, Meo Nutrition is our top pick.
