Ashwagandha has become one of the most sought-after plants in recent years. In a world where chronic stress has become the norm, this centuries-old adaptogenic plant stands out as a valuable ally for restoring balance and serenity. But not all ashwagandha extracts are created equal. Let’s take a closer look at KSM-66, the gold-standard form - and why it makes all the difference.
Understanding ashwagandha: a unique adaptogenic plant
Ashwagandha (Withania somnifera) is a plant used in Ayurvedic medicine for thousands of years. It is called an “adaptogenic” plant because it helps the body adapt to sources of stress - physical, mental, or emotional - to restore a state of balance.
Its mechanism of action is twofold. On the one hand, it helps modulate the secretion of cortisol, the stress hormone that is present in excess during prolonged periods of tension. On the other, it interacts with GABA receptors, which are involved in regulating nervous system activity, promoting relaxation and better sleep.
These are the withanolides - compounds naturally present in the root - that are responsible for these effects. Their concentration varies considerably from one extract to another. This is where choosing the right form becomes crucial.
KSM-66 vs. other extracts: what is the real difference?
There are two main categories on the market:
Standard root or leaf extracts, with low concentrations, often containing 1-2% withanolides. Their concentration is low and their effectiveness limited, even at high doses.
Ashwagandha KSM-66®: a patented extract made exclusively from the root, with a guaranteed withanolide content of at least 5%. It is produced using an extraction process faithful to Ayurvedic tradition, which preserves the whole plant and ensures the stability of its active compounds. It is currently the most clinically documented form of ashwagandha.
What the science says about KSM-66
A placebo-controlled clinical study conducted on 58 adults experiencing chronic stress over 8 weeks, at a dose of 250 mg/day, showed significant results:
A significant reduction in blood cortisol after 8 weeks (from 16.3 to 13.61 µg/dL). A reduction in perceived stress measured using the PSS scale: score decreasing from 22.7 to 15. An improvement in sleep quality (score decreasing from 5.85 to 3.79). Effects appeared after 4 weeks and were confirmed after 8 weeks.
How to choose the right ashwagandha
- Source: root only - leaf extracts contain fewer active compounds.
- Withanolide content: at least 5% for a clinically relevant effect.
- Patented KSM-66® form: the most scientifically documented.
- Dosage: 250 to 600 mg/day according to studies - beware of token doses.
- Overall formulation: ashwagandha works better in synergy with magnesium and B vitamins.
The Epycure Cortisol Balance Course
The Cortisol Balance Course is formulated around 250 mg of Ashwagandha KSM-66® per day - the exact dose used in the clinical study, with a guaranteed withanolide content of 5%.
Ashwagandha has adaptogenic properties and helps the body cope with stress, supporting physical and mental well-being in cases of fatigue or exhaustion (EFSA).
The formula is complemented by a synergy designed to address chronic stress from every angle:
- Magnesium bisglycinate (56.25 mg) - one of the best-absorbed forms. It contributes to the normal functioning of the nervous system and helps reduce fatigue (EFSA). Particularly important in cases of chronic stress, which depletes magnesium reserves.
- L-tryptophan (100 mg) - a precursor to serotonin, supporting emotional balance and sleep.
- Vitamins B5, B6, B9, B12 - B5 contributes to the normal synthesis of steroid hormones; B6 supports the regulation of hormonal activity; B9 and B12 contribute to normal psychological functions (EFSA).
Formula free from hormones, with no euphoric or stimulating effect. Made in France, B Corp certified, with full traceability. A 3-month course is recommended: initial effects from day 15, with lasting cortisol regulation from day 60.
In summary
KSM-66 ashwagandha is much more than a trend: it is the best-documented form of a centuries-old adaptogenic plant, at a clinically validated dose. Choosing the right extract, at the right dosage, in a formula designed for synergy - that is the key to helping your body restore its balance in the face of stress.
