Our take on the Natural Factors R-Alpha Lipoic Acid 100 mg

Natural Factors R-Alpha Lipoic Acid is a vegetarian capsule supplement supplying 100 mg of the R-form of alpha-lipoic acid per capsule. The R-form is the natural isomer, and the brand states it stays in the body longer than the common S-form found in many cheaper alpha-lipoic acid products. Alpha-lipoic acid is a fat- and water-soluble antioxidant that works alongside vitamins C and E and glutathione, and it plays a role in energy production. It suits adults looking for a clean-label antioxidant supplement, including vegetarians and vegans, and those avoiding gluten, soy, dairy and common allergens.

About the Natural Factors R-Alpha Lipoic Acid 100 mg

Natural Factors R-Alpha Lipoic Acid provides 100 mg of R-alpha-lipoic acid in each vegetarian capsule. The R form stays in the body significantly longer than the regular S form of alpha-lipoic acid. It is also involved in energy production.

Alpha-lipoic acid is a very small molecule that is absorbed efficiently and crosses cell membranes easily. It is both fat- and water-soluble, so it can quench free radicals inside and outside the cell. It works together with vitamin E and vitamin C to protect the entire cell from oxidative stress. It also directly recycles vitamin C and glutathione and indirectly recycles vitamin E.

The recommended adult dose is 1 capsule 2 times daily, or as directed by a health care practitioner. Consult a health care practitioner before use if you are pregnant or breastfeeding, or if you have diabetes. Keep out of the reach of children.
