Description:
Alpha-lipoic acid is an organic compound found in all human cells.
It’s made inside the mitochondrion — also known as the powerhouse of cells — where it helps enzymes turn nutrients into energy (1Trusted Source).
What’s more, it has powerful antioxidant properties.
Alpha-lipoic acid is both water- and fat-soluble, which allows it to work in every cell or tissue in the body. Meanwhile, most other antioxidants are either water- or fat-soluble (2Trusted Source).
The antioxidant properties of alpha-lipoic acid have been linked to several benefits, including lower blood sugar levels, reduced inflammation, slowed skin aging, and improved nerve function.
Alpha lipoic acid is also known as thioctic acid; it’s extremely vulnerable to degradation by sunlight. Higher concentrations (5% or greater) are capable of causing a burning or stinging sensation on skin.
