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.
