Alpha-lipoic acid exists in two chiral forms: R, naturally present in the body and biologically active, and S, from chemical synthesis with limited physiological relevance. Most supplements offer a racemic 50/50 mix. Dynveo’s Bio-Enhanced Na-RALA stands apart, with over 99.4% R-form purity, guaranteeing nearly all ingested material is the biologically relevant form. Sodium binding gives remarkable thermal stability, with no polymerisation up to 150°C for 6 hours — eliminating the storage-degradation issues of unstabilised forms.

Sodium R-lipoate stands out through dual solubility — active in both aqueous and lipid environments, letting it work across all cell compartments, from lipid membranes to aqueous cytoplasm. R-alpha lipoic acid also acts as a cofactor for several mitochondrial enzymes involved in energy metabolism, and supports the regeneration of other endogenous antioxidants like glutathione and vitamin C.

Take 1 to 2 capsules a day, preferably on an empty stomach or between meals. If taking 2 capsules, split between morning and afternoon to prolong the antioxidant effect. Each capsule provides 300mg sodium R-lipoate. The 300-capsule format covers 5–10 months depending on dose.

Do not exceed the recommended daily dose. Not recommended for pregnant or breastfeeding women without prior medical advice. Those on medication, particularly blood-sugar-lowering drugs, should consult a healthcare professional — alpha-lipoic acid can influence blood sugar; diabetics should inform their doctor. Store in a cool, dry place away from light and heat, out of reach of young children.

What’s the difference from standard alpha-lipoic acid?

Standard alpha-lipoic acid is usually a racemic mix (50% active R form, 50% weakly active S form). Sodium R-lipoate is over 99.4% biologically active R form, stabilised by sodium binding, with markedly higher bioavailability and storage stability.

What can I combine sodium R-lipoate with?

It pairs effectively with milk thistle (silymarin) for liver support, coenzyme Q10 for mitochondrial energy metabolism, and omega-3 (DHA/EPA) for cardiovascular and brain protection.

Is the 300-capsule format better value than the 60-capsule one?

Yes — a more economical option for users wanting regular supplementation over several months; at 1–2 capsules a day, it covers 5–10 months, and the stabilised form keeps perfectly at room temperature.
