Frequently Asked Questions
KSM-66 Ashwagandha

What is KSM-66 Ashwagandha and why is it better?

KSM-66® is the highest concentration, full-spectrum root extract of Ashwagandha available today. Unlike generic extracts that use leaves, KSM-66 focuses on the root, ensuring a consistent and potent dose of withanolides (active compounds) clinically proven to reduce stress and anxiety.

How long does Ashwagandha take to work for stress?

As an adaptogen, Ashwagandha works cumulatively. While some people feel a calming effect within days, significant reductions in cortisol (stress hormone) levels and improvements in anxiety typically peak after 4 to 8 weeks of consistent daily supplementation.

Can I take Ashwagandha to help me sleep?

Yes, Ashwagandha is excellent for sleep support. By lowering cortisol levels that can keep you "wired" at night, it promotes relaxation and improves overall sleep quality. Many users find it helps them fall asleep faster and wake up feeling more refreshed.

Is this product just Ashwagandha or a blend?

Our Ashwagandha Botanical Complex is a synergistic blend. It combines the potent KSM-66 extract with supporting nutrients like Zinc, Vitamin B6, and Magnesium. This combination further supports the nervous system, cognitive function, and hormonal regulation for comprehensive wellbeing.

Does Ashwagandha affect testosterone levels in men?

Research suggests that Ashwagandha can support healthy testosterone levels in men, primarily by reducing stress (cortisol). High cortisol acts as a brake on testosterone production, so by managing stress, Ashwagandha naturally supports vitality, strength, and reproductive health.
