Super R-Lipoic Acid
240 mg, 60 vegetarian capsules
Item Catalog Number: 01208EU
Published studies have shown the critical importance of lipoic acid in preserving youthful cellular energy by supporting healthy mitochondrial function. Unlike other forms of lipoic acid, Super R-Lipoic Acid is more bioavailable, stable, and potent, achieving 10–30 times higher peak blood levels than pure R-lipoic acid. This unique sodium-R-lipoate can help you reach peak plasma concentrations within just 10–20 minutes of supplementation. Super R-Lipoic Acid provides more of the active "R" form than conventional alpha-lipoic acid products. Try this next-generation lipoic acid today!Benefits at a Glance
Unlike other forms of lipoic acid, Super R-Lipoic Acid is more stable in the body. The increased stability of this enhanced formulation is the reason for its greater absorption and bioavailability compared with R-lipoic acid.
The superior antioxidant effects of R-lipoic acid are already well-known for supporting healthy mitochondrial function. Now, Super R-Lipoic Acid provides even more potent benefits for preserving youthful cellular energy levels.

R-Lipoic Acid is the naturally occurring, biologically active form of alpha-lipoic acid found in the body and food sources. Standard alpha-lipoic acid supplements contain a 50/50 mixture of R and S forms, but only the R form is produced naturally by human cells and utilized by mitochondria. R-Lipoic Acid is significantly more bioavailable and potent than the synthetic S form, with studies showing it achieves 10-30 times higher blood levels. This superior absorption means R-Lipoic Acid delivers more powerful antioxidant protection and metabolic support at lower doses than standard lipoic acid supplements.
R-Lipoic Acid is a critical cofactor for mitochondrial enzymes involved in energy production from glucose and fats. It works within mitochondria to support efficient conversion of nutrients into ATP, the cellular energy currency. As we age, mitochondrial function declines and R-lipoic acid levels decrease, contributing to reduced energy and increased oxidative stress. Supplementation helps restore optimal mitochondrial function, supporting healthy energy metabolism throughout the body. R-Lipoic Acid also chelates metals and recycles other antioxidants like vitamins C and E, glutathione, and CoQ10, creating a comprehensive antioxidant network that protects mitochondria from damage.
R-Lipoic Acid provides comprehensive metabolic and antioxidant support. It helps maintain healthy blood sugar metabolism by enhancing insulin sensitivity and glucose uptake into cells. As a universal antioxidant working in both water and fat-soluble environments, it protects cells throughout the body from oxidative damage. R-Lipoic Acid supports cardiovascular health, cognitive function, and healthy aging by protecting against glycation and oxidative stress. It supports nerve health and comfortable nerve function, particularly beneficial for peripheral nerves. The compound also supports liver detoxification, healthy inflammatory responses, and helps maintain healthy weight management through improved metabolic efficiency.
R-Lipoic Acid enhances insulin function and glucose metabolism through multiple mechanisms. It activates AMPK, an enzyme that signals cells to increase glucose uptake and utilization. Studies show it improves insulin sensitivity, helping the body use insulin more efficiently to maintain healthy blood sugar levels already within normal range. R-Lipoic Acid also protects against oxidative stress caused by elevated blood sugar, preventing glycation damage to proteins and tissues. Clinical research demonstrates significant improvements in glucose metabolism markers with R-lipoic acid supplementation, making it valuable for metabolic health support and maintaining healthy hemoglobin A1c levels.
For optimal absorption, take R-Lipoic Acid on an empty stomach at least 30 minutes before meals, as food can significantly reduce absorption. However, if you experience stomach upset, taking with a small amount of food is acceptable. The short half-life of R-lipoic acid means splitting doses throughout the day maintains more stable blood levels, though once-daily dosing still provides benefits. Start with recommended doses and increase gradually if needed. Take consistently at the same times daily for best metabolic support. R-Lipoic Acid works synergistically with other mitochondrial nutrients like CoQ10, acetyl-L-carnitine, and B vitamins for comprehensive cellular energy support.
Results: Clinical studies demonstrate R-Lipoic Acid is significantly more bioavailable than racemic alpha-lipoic acid, achieving plasma concentrations 10-30 times higher than S-lipoic acid, providing superior antioxidant protection and metabolic benefits at equivalent or lower doses.
