R-alpha lipoic acid with BioEnhanced® Na-RALA

R-Alpha Lipoic Acid Bio Enhanced® Na-RALA by Doctor's Best

Doctor's Best's R-Alpha Lipoic Acid contains a combination of dextrorotatory (R) alpha lipoic acid and biotin. R-alpha lipoic acid is a fatty acid that occurs naturally in every cell of the body, where it plays a vital role in energy metabolism. Biotin, or vitamin B8, belongs to the B vitamins and is the beneficiary of various health claims. The two ingredients together form a powerful synergy.

Water- and fat-soluble

R-alpha lipoic acid is a natural substance first isolated in 1951. At first it was thought to be a B vitamin; it later turned out to be a sulfur-containing fatty acid and antioxidant. As a nutrient, it has powerful and unique characteristics. The antioxidant is both water- and fat-soluble. This molecular capacity renders R-alpha lipoic acid available to almost all body systems. As we age, the endogenous ability to synthesize alpha lipoic acid diminishes.

The universal antioxidant: widely applicable

R-alpha lipoic acid is a molecular multitasker catering to a wide variety of functions. Because the human body itself can produce small amounts, it is seen as a condition-specific nutrient. This means that you must ensure adequate intake either through food or nutritional supplements. R-alpha lipoic acid is found in small amounts in the diet, notably in organ meats. It is well absorbed from the gastrointestinal tract and can easily disperse throughout the body.

Natural R-alpha lipoic acid versus synthetic S-alpha lipoic acid

Alpha lipoic acid comes in two forms, called R-alpha lipoic acid and S-alpha lipoic acid. R and S alpha lipoic acid are enantiomeric isomers: molecules that appear as mirror images of each other. R-alpha lipoic acid is naturally synthesized by humans, animals and plants. S-alpha lipoic acid is formed during the chemical synthesis of alpha lipoic acid, which produces a racemic mixture (two equal parts) of the two enantiomers. S-alpha lipoic acid is often used in research.

BioEnhanced® Na-RLA

It is well-documented that R-alpha lipoic acid is more bioavailable than the S form. Doctor's Best Stable R-alpha Lipoic Acid contains BioEnhanced® Na-RLA, a stable form of the sodium salt of R-alpha lipoic acid (RLA). Pure R-alpha lipoic acid is a highly unstable molecule that tends to polymerize when exposed to heat, light or moisture. BioEnhanced® Na-RLA is a stabilized form of R-alpha lipoic acid that does not break down at high temperatures. It therefore has a higher bioavailability and does not contain any residual solvents.
