FAQ
The doubts in your head? We’ve already answered them here.
We moved from 500 mg to a clinically studied 600 mg dose because that’s where KSM-66® consistently shows better results for stress, sleep, and recovery in 48+ clinical studies.
We also looked at higher doses, but they don’t offer meaningful added benefits and may increase chances of side effects like drowsiness or discomfort. So 600 mg is the sweet spot – maximum effectiveness, without compromising safety.
Rasayanam uses authentic KSM-66®, a patented root-only extract standardized to 5% withanolides, ensuring consistent potency and effectiveness. Many other supplements use mixed plant parts or unstandardized powders.
It is suitable for individuals experiencing high stress, mental fatigue, low energy, poor sleep quality, or reduced stamina. It can benefit professionals dealing with daily pressure, active individuals seeking better recovery and performance, and men looking to support strength and hormonal balance. If you are pregnant, breastfeeding, managing a medical condition, or taking medication, consult a healthcare professional before use.
Yes. Ashwagandha is an adaptogen, meaning it helps the body adapt to stress. Clinical studies show KSM-66® supports balanced cortisol levels, which may help reduce stress and improve overall emotional well-being.
Studies have shown that KSM-66® may help support healthy testo-levels, strength, stamina, and recovery – particularly in men experiencing stress or engaging in resistance training.
Many users report noticeable improvements in stress and sleep within 3-4 weeks. Benefits related to strength, stamina, and hormonal support may take 4-8 weeks of consistent use.
No. Ashwagandha is an adaptogen, not a sedative. It helps the body adapt to stress. Some users report better sleep quality at night, but it does not cause daytime drowsiness.
KSM-66® has been evaluated in multiple human studies and is considered safe when taken at recommended dosages. Consistency is key for optimal benefits.
KSM-66® Ashwagandha is made using a patented milk-based extraction process to extract the beneficial compounds from the root. This may give the extract a mildly neutral or slightly milky taste. No milk powder or dairy ingredients are added to the capsule.
However, since milk is used during extraction, people with severe milk allergies or dairy sensitivities should consult a doctor before use.
Ashwagandha is a natural plant extract, so the powder may slightly change colour over time when exposed to air, moisture, or heat after opening. This is a natural variation and does not affect the product’s quality or effectiveness. For best results, keep the bottle tightly closed and store it in a cool, dry place.
Rasayanam Ashwagandha KSM-66® does not contain milk or milk powder as an added ingredient. However, the patented KSM-66® Ashwagandha extract is manufactured using a traditional process involving milk. As a result, trace amounts of milk-derived components may be present in the final extract.
If you have a milk allergy, lactose intolerance, or severe sensitivity to milk-derived ingredients, we recommend consulting your healthcare professional before use.
Additionally, as the patented KSM-66® extract is manufactured using a traditional process involving milk, this product does not meet vegan standards.
