Sodium R-lipoate results from combining natural R-alpha-lipoic acid with a sodium atom. This combination considerably improves the molecule’s stability and solubility. Where raw R-alpha-lipoic acid degrades rapidly under heat, light and humidity, the sodium R-lipoate form retains its integrity even at room temperature. The Bio-Enhanced Na-RALA name, a registered trademark of GeroNova, refers to this specific form, produced via a patented process that guarantees an enantiomeric purity above 99.4% in the R form — the only form naturally produced and used by the human body.

Most alpha-lipoic acid supplements offer a 50/50 racemic mix of R and S forms, of which only the R form is biologically active. Sodium R-lipoate contains almost exclusively the R enantiomer, maximising the actual intake of active compound. Additionally, its sodium-stabilised structure prevents polymerisation, a phenomenon by which molecules clump together and become unusable by the body. The measured result is a bioavailability up to 21 times higher than non-stabilised alpha-lipoic acid, meaning the body fully benefits from each dose ingested.

R-alpha-lipoic acid is one of the few antioxidants able to act in both watery and fatty environments, allowing it to protect all cellular compartments. It directly participates in mitochondrial energy metabolism as an enzymatic cofactor, supporting cellular ATP production. Its ability to recycle other antioxidants such as glutathione, vitamin C and vitamin E makes it a central player in the body’s antioxidant defence network.

The recommended dose is 1 to 2 capsules per day, ideally before meals to stimulate intestinal absorption. Athletes may prefer taking it after exercise. Sodium R-lipoate pairs favourably with coenzyme Q10 for mitochondrial energy support, polyphenols to widen the antioxidant spectrum, and silymarin (milk thistle) for liver protection. Dynveo also offers a 100 mg dosage for those wanting a more gradual approach.

Not recommended for pregnant or breastfeeding women without medical advice. If on medication, consult a healthcare professional before supplementing.

What is the difference between sodium R-lipoate and standard alpha-lipoic acid?

Standard alpha-lipoic acid is a mix of the R (active) and S (mostly inactive) forms, unstable and prone to polymerisation. Sodium R-lipoate contains only the natural R form, stabilised by sodium, offering bioavailability up to 21 times higher and stable storage at room temperature.

What benefits can I expect from this antioxidant?

Sodium R-lipoate helps protect cells against free radicals, supports mitochondrial energy metabolism, participates in recycling glutathione and vitamins C and E, and is of interest for blood sugar balance. Athletes value it for recovery and seniors for cellular ageing prevention.
