What is Fermanolide™?

Fermanolide™ is fermented ashwagandha, a much-appreciated medicinal herb in Ayurveda. The most valuable part of ashwagandha is the root. This wonderful herb has been made even more powerful than it already is through a patented and innovative Biotransforming Fermentation Technology!

The root of ashwagandha contains many active compounds of which the following are the most important:

  • steroidal lactones  (steroidal saponins) such as withanolides (A-D & Z), withaferin A, withanone, …
  • withanoside series  of steroidal lactones (usually withanoside IV and VI), sominone (active metabolite and aglycon of withanoside IV)
  • withanolide glycosides  (saponins), which are referred to as sitoindosides (or glycowithanolides)
  • alkaloids  as a.o. isopelletierine, anaferine, cuscohygrine, anahygrine, …
  • ashwagandhanolide & withanolide sulfoxide

At present, more than 12 alkaloids, 40 withanolides, and several sitoindosides (a withanolide containing a glucose molecule at carbon 27) have been isolated and reported from aerial parts and roots of Withania species.

Why fermenting ashwagandha?

Biotransformation of secondary plant substances

The most active components of ashwagandha are the withanolides, withanosides and glycowithanolides, all calledsaponins. The focus is mainly on the conversion of the original glycolised saponines to the more active form through our proprietary lactic acid fermentation. Due to their bulky molecular structures, the saponins are poorly membrane permeable and prone to degradation. The mass of the original withanolides, withanosides and glycowithanolides decreases after fermentation due to the removal of the sugar molecules. This process is called deglycosylation. The form is the so called aglycone form, which is permeable and hence directly bioactive. Smaller molecules that are very active and well-studied, penetrate the body more easily!

Withaferin A is degraded by fermentation to a negligible level and therefore there is no risk of cell toxicity.

A specific probiotic strain in the fermentation process is able to break down withaferin A. Its genotoxic potential should be carefully considered for functional foods and dietary supplements. The amount of withaferin A in Fermanolideis less than 0.01%, making it very safe for human consumption.

The flavonoids are broken down into smaller active antioxidant molecules by fermentation

Formation of SOD-like substances that are not destroyed in the digestive tract and perform the same function as superoxide dismutase (SOD)!

The content of withanolide A has been increased by about 70 % after fermentation at a stable level to ensure functional physiological activity.

A study shows that in addition to the strong antioxidant property, withanolide A provides increased neuroprotection by modulation of endogenous glutathione content in hippocampus during exposure to hypobaric hypoxia.

Withanolide A increases glutathione biosynthesis in neuronal cells by upregulating GCLC level through Nrf2 pathway in a corticosterone dependent manner.

The total withanolides content has been increased by 25 %

A targeted lactic acid fermentation process ensures a substantial increase in the total withanolides content.

Much lower daily dose needed

By the high bioavailability & rapid absorption in the small intestine and the fact that the biotransformed molecules are more stable & stay in the body for at least five days, a daily dose of 150 mg is under normal circumstances enough!


Many studies show the therapeutic properties of ashwagandha. It is therefore scientifically very well founded. However, it is important that the saponins are available in their easily absorbable form because this is a condition for the therapeutic power of this promising plant!
