Alpha-Lipoic Acid 600mg

180 Veggie Caps DRB-00249

Cellular superhero.

Alpha-lipoic acid (ALA) has been called a “universal antioxidant” because it is both water and fat soluble—this allows it to work in every cell or tissue in the body. As we age, our ability to synthesize ALA decreases and levels of oxidized proteins (these little buggers interfere with mitochondrial efficiency) increase. Supplementing with ALA, also known as a “mitochondrial nutrient,” addresses this head on.* Help protect your cells with a daily dose of Doctor’s Best ALA.*

This Stuff Really Works!! I take this in conjunction with R-lipoic acid because Alpha lipoic acid is actually a combination of R and S. S is the byproduct when making this and offers no benefit to the body. Overall, Doctors Best is my go to source for all vitamin healthcare.

Excellent product. It helped a severe diabetic maintain a much healthier blood sugar balance and improved neuropathy pain and function. Alpha-lipoic acid has so many uses, it is like magic in a bottle. Good quality supplement. Thank you!

ALA, so much more than an acronym.

Alpha-lipoic acid (ALA) is an organic compound made inside our mitochondrion, also known as the powerhouse of cells. Here it helps convert enzymes to energy and acts as an antioxidant, defending your system against free radicals. It also helps us metabolize glucose thereby promoting healthy blood sugar levels as part of a healthy diet.* Three small letters that can deliver big results. Give it a try!

Suggested Use

Each veggie capsule delivers 600 mg of ALA. Take one capsule daily, with or without food.


It is synthetic.

When ALA (Alpha Lipoic Acid) is manufactured synthetically, it occurs as a racemic mixture of the 2 forms, R and S. The R form is found naturally in the body and is considered the "active" form. Most basic ALA products are a 50:50 mixture of both R & S forms.

It contains 50% R-form and 50% S-form.
