Frequently Asked Questions

OptiBio uses 100% KSM-66® root extract—the most clinically studied ashwagandha in the world (22+ peer-reviewed studies). We provide the clinical dose (600mg), standardized to 5% withanolides, and every batch is third-party tested for purity and potency.

Most brands use cheaper leaf/root blends with minimal withanolide content (1-2%) and no clinical backing.

Yes. KSM-66® has been used safely in clinical trials for up to 12 months with no adverse effects. Ashwagandha has been used in Ayurvedic medicine for over 3,000 years.

However, as with any supplement, we recommend consulting your healthcare provider if you're pregnant, nursing, or taking medications.

Every bottle has a QR code that links to the full third-party lab report for that specific batch. You can verify:

• Withanolide content (5%+)
• Heavy metal testing (lead, mercury, arsenic)
• Microbial contamination
• Pesticide residues
• GMO testing

We also manufacture in a GMP-certified facility in the USA.

Most people notice initial benefits (better sleep, reduced stress) within 1-2 weeks. However, clinical studies show that the full spectrum of benefits (cognitive enhancement, physical performance) develops over 8-12 weeks of consistent daily use.

This is why we offer a 90-day money-back guarantee—we want you to experience the complete transformation.

For sleep: Take in the evening with dinner.

For stress/focus: Take in the morning with breakfast.

For physical performance: Split the dose (1 morning, 1 evening).

The most important thing is consistency—taking it at the same time daily.

Yes, ashwagandha is generally safe to combine with other supplements. It's commonly taken alongside vitamins, minerals, omega-3s, and other adaptogens.

Avoid combining with sedative medications or thyroid medications without consulting your doctor, as ashwagandha may enhance their effects.

We offer a 90-day money-back guarantee. If you don't feel calmer, sleep better, and think more clearly after 90 days of daily use, simply email us for a full refund. You can even keep the bottle.
