What Alpha-Lipoic Acid does
Alpha-lipoic acid (ALA) is a caprylic acid-derived antioxidant synthesized in the mitochondria, used as a supplement for managing chronic diseases characterized by oxidative stress. It has been studied most for diabetic neuropathy, where it is described as enhancing nitric oxide-mediated endothelium-dependent vasodilation and improving microcirculation, and it has been explored for slowing the onset of metabolic syndrome. The article notes there is still a need for more studies on its benefits in other conditions such as HIV/AIDS, liver disease, and weight loss, and that ALA has no approved indication as a dietary supplement. — per StatPearls (NCBI Bookshelf); not medical advice.
Forms & absorption
ALA is available as an oral supplement and as an intravenous injection; studied doses include 300 mg over 3 months and 600 mg to 1800 mg daily for up to 6 months orally, and 600 mg daily intravenously for neuropathic symptoms. The article states that absorption, volume of distribution, metabolism, and excretion are not well-established for ALA.
Food sources of Alpha-Lipoic Acid
Alpha-lipoic acid is found naturally in red meat, beets, carrots, potatoes, spinach, and broccoli, and is also synthesized in the mitochondria.
Can you get too much Alpha-Lipoic Acid?
Adults can take up to 2400 mg without reported harmful adverse effects, and a daily dose of 200 mg/day to 2400 mg/day is deemed safe in adults, though there is no reported safe dose in children; the most common adverse effects reported are headache, heartburn, nausea, and vomiting. In animal studies, high intravenous doses caused necrosis including in the liver, and one human case involved status epilepticus. — per StatPearls (NCBI Bookshelf).
Alpha-Lipoic Acid — interactions & cautions
Patients should consult a physician before use if they have liver disease, high alcohol consumption, diabetes (ALA is known to lower blood sugar), a thyroid disorder, or thiamine deficiency, and should stop using ALA immediately if an allergic reaction such as skin rash, nausea, or vomiting occurs. Research shows ALA supplementation during pregnancy is safe but more data is needed to establish its role, while there is a lack of reliable data regarding safety during breastfeeding. — per StatPearls (NCBI Bookshelf).
