Alpha Lipoic Acid
ALA — Universal Antioxidant & Glucose Sensitizer
What is Alpha Lipoic Acid?
Alpha Lipoic Acid (ALA) is a naturally occurring cofactor for mitochondrial enzyme complexes that functions as a universal antioxidant — being both water and fat-soluble, it protects cellular membranes and aqueous compartments simultaneously. It regenerates vitamins C and E and glutathione, improves insulin sensitivity, chelates heavy metals, and has demonstrated neuroprotective properties. It is used clinically for diabetic neuropathy in Germany (as a prescription drug) and globally as a supplement.
ALA is reduced to DHLA (dihydrolipoic acid) inside cells, creating a potent antioxidant pair that scavenges ROS in both lipid and aqueous environments. DHLA regenerates oxidized glutathione, vitamin C, and vitamin E back to their active forms — amplifying the entire antioxidant network. ALA also activates AMPK (improving insulin sensitivity and metabolic rate), inhibits NF-kB (anti-inflammatory), and chelates heavy metals like mercury and lead.
Research Evidence
Multiple Phase 3 RCTs demonstrate IV and oral ALA significantly reduces symptoms of diabetic peripheral neuropathy. Approved as a drug for this indication in Germany.
Controlled trials show ALA improves insulin-mediated glucose uptake and reduces HbA1c in type 2 diabetics through AMPK activation.
Human and animal studies show ALA protects neurons from oxidative damage. Studied for Alzheimer's, Parkinson's, and cognitive decline prevention.

Reconstitution / Preparation
This compound does not require reconstitution — it is available as an oral or pre-mixed formulation.
Frequently Asked Questions
Should I take ALA with or without food?
Without food — ALA absorption is significantly reduced when taken with meals. Take ALA 30-60 minutes before eating for maximum absorption. The R-form (R-ALA) absorbs better than racemic ALA regardless of food timing.
Does Alpha Lipoic Acid chelate mercury?
Yes. ALA chelates mercury and other heavy metals, which is both a potential benefit (detoxification) and a concern. If mercury amalgam fillings are present or recent amalgam removal has occurred, ALA supplementation should be avoided until the amalgams are removed and the body has had time to clear initial mercury load — ALA can redistribute mercury to the brain in these circumstances.
