Alpha Lipoic Acid

Q: What is the difference between R-ALA and racemic ALA?

Racemic alpha-lipoic acid is synthetically produced and is a mixture of the R- and S-forms. Pure R-alpha-lipoic acid (R-ALA) corresponds to the natural, body-identical form and is the biologically active variant. R-ALA is often obtained through biotechnological fermentation and subsequently purified.

Q: What should I look for when buying?

What matters most are the declared form and the content per serving. If you want the natural, active variant, choose pure R-ALA. Because alpha-lipoic acid can be sensitive, stabilised forms make sense. Also look for lab-tested purity. Our alpha-lipoic acid is vegan, lab-tested and also available as the R-form.

Q: What forms is alpha-lipoic acid available in?

Alpha-lipoic acid is mainly available as a capsule, with a clearly declared content per serving. Pure R-ALA is often labelled separately, so you can identify the natural, body-identical form. Because the substance can be sensitive, stabilised variants are sometimes used. At Scheunengut, it is vegan and lab-tested.

Buy Alpha-Lipoic Acid – R-ALA and Stabilised Forms

Alpha-lipoic acid (ALA, also known as thioctic acid) is a sulphur-containing organic compound that occurs in the human body and is present in both water- and fat-soluble environments. Chemically, it is one of the dithiol compounds and carries a characteristic five-membered ring with two sulphur atoms. In this category, you'll find alpha-lipoic acid from Scheunengut – including the biologically active R-form (R-ALA), vegan and lab-tested.

Origin & Extraction

Two variants are distinguished: synthetically produced racemic alpha-lipoic acid, a mixture of the R- and S-form, and pure R-alpha-lipoic acid, which corresponds to the natural form found in the body. R-ALA is often obtained through biotechnological fermentation and then purified.

Standardisation & Format

The decisive factors are the declared form and the content per serving. Pure R-ALA is often stated in milligrams per capsule, whereas racemic material contains an S-proportion. Alpha-lipoic acid is usually offered as a capsule or powder. As a sulphur-containing compound, it is thematically placed alongside other substances such as NAC.

What to Look for When Buying

Form & content: pure R-ALA or racemic ALA, transparently declared
Origin: fermentation-derived R-form versus synthetic racemate
Vegan and free from unnecessary additives
Independently lab-tested purity

Häufige Fragen zu Alpha Lipoic Acid

What is alpha-lipoic acid?

Alpha-lipoic acid (ALA, also known as thioctic acid) is a sulphur-containing organic compound that also occurs in the human body. What makes it distinctive is that it is present in both water- and fat-soluble environments. Chemically, it belongs to the dithiol compounds and carries a characteristic five-membered ring with two sulphur atoms.

What is the difference between R-ALA and racemic ALA?

Racemic alpha-lipoic acid is synthetically produced and is a mixture of the R- and S-forms. Pure R-alpha-lipoic acid (R-ALA) corresponds to the natural, body-identical form and is the biologically active variant. R-ALA is often obtained through biotechnological fermentation and subsequently purified.
