Frequently Asked Questions

What is KSM-66® ashwagandha good for?

KSM-66® is a root only ashwagandha extract, standardized to 5% withanolides and produced without alcohol or synthetic solvents. People most often reach for it to support a healthy stress response, restful sleep, and calm focus.† It is an adaptogen, so it works gradually with consistent daily use rather than like a stimulant. Most people give it 2 to 4 weeks to judge how it fits their routine.

Individual experiences vary.

What’s the difference between KSM-66® and regular ashwagandha?

Are there any side effects?

If you are pregnant, nursing, taking medication, have a medical condition, or have questions about whether ashwagandha is right for you, consult your healthcare provider before starting any new supplement.

Can I take this with other supplements?

If you take prescription medications or other supplements, consult your healthcare provider before adding any new supplement to your routine.

What if it doesn’t work for me?

We offer a 90 day money back guarantee. If Optibio is not the right fit for your routine, contact us for support under the guarantee.

Can you take ashwagandha every day?

Yes. Ashwagandha is typically taken daily as part of a consistent routine. KSM-66® is an adaptogen, which means its effects build gradually with regular use. It is typically taken daily for 8 to 12 weeks to get the full effect. As with any supplement, consult your healthcare provider if you have questions about long term use.

Should I take ashwagandha in the morning or at night?

Either works. It depends on your goals. Some people prefer morning dosing for stress resilience throughout the day, while others take it in the evening to support relaxation and sleep quality. You can also split your two capsules: one in the morning and one in the evening. There is no wrong time.

Should I take ashwagandha with or without food?

We recommend taking Optibio with food. While ashwagandha can be taken on an empty stomach, pairing it with a meal supports absorption and is gentler on digestion. A light breakfast or snack is sufficient.

Can I take ashwagandha and coffee together?

Yes. There is no known adverse interaction between ashwagandha and caffeine. Many people take their morning Optibio capsule alongside coffee. Ashwagandha works through a different pathway (the HPA axis and stress response system) than caffeine, so they complement rather than conflict.

How much KSM-66® ashwagandha should I take per day?

Optibio delivers 600mg of KSM-66® ashwagandha root extract per daily serving (2 capsules). This is standardized to 5% withanolides, the key bioactive compounds. Do not exceed the recommended dose unless directed by your healthcare provider.

How do I take it?

Take 2 capsules daily, preferably with food. You can take both capsules together or split them (one in the morning, one in the evening). For sleep support, some customers prefer taking their dose in the evening.

How does FDA oversight work for supplements?

Dietary supplements are regulated differently from prescription drugs. Optibio keeps quality language limited to approved claims: Manufactured in the USA with globally sourced ingredients, Manufactured in a GMP certified facility, and Third party tested for purity and potency.

How does Subscribe & Save work?

Subscribe & Save gives you 26% off every order plus free shipping on every delivery. Your supply ships automatically every 45 days, so you never run out. You can skip a shipment or cancel anytime from your account. No contracts, no commitments, no penalties.

Can I skip, pause, or cancel my subscription?

Absolutely. You have full control over your subscription. Log into your account to skip your next delivery, pause your subscription for as long as you need, or cancel entirely, all with just a few clicks. There are no cancellation fees and no minimum number of orders required.

When will I be charged for my subscription?

You're charged when your order is placed, and then again before each scheduled delivery, every 45 days. You'll always receive an email reminder before your next order ships, giving you time to make changes or skip if needed.

Should I take ashwagandha capsules, powder, or gummies?

Ashwagandha is sold in capsules, powder, and gummies, but the format affects both dose accuracy and the active compounds you actually receive. KSM-66® ashwagandha capsules like Optibio deliver the exact full 600mg dose, with no added sugar, fillers, or flavor masking. KSM-66® ashwagandha powder can be effective but requires careful measuring and has a strong, bitter taste that's difficult to mask in food. KSM-66® ashwagandha gummies typically contain 1 to 3g of added sugar per serving and are often underdosed at 100 to 250mg per gummy, well below a full dose. For consistent, accurate dosing without added sugars, capsules are the cleanest delivery format for KSM-66®.
