How it works

One root, taken daily, given time.

Optibio is not a jolt or a sedative. It is 600mg of KSM-66® ashwagandha root, the most clinically studied ashwagandha extract, taken as a small daily habit that builds over weeks.

The science, plainly.

No mystery blend, no buzzwords. Three things make this work.

01

An adaptogen, not a stimulant

Ashwagandha is studied to support the body's response to everyday stress. It works with your baseline instead of spiking and crashing it. Results vary.

02

Root only, standardized

KSM-66® uses the root alone, standardized to 5% withanolides, so every capsule carries the same strength as the last one.

03

The full studied amount

600mg per day is the serving used in published human research on KSM-66. Two capsules give you all of it, no dusting behind a proprietary blend.

Your daily ritual.

The whole routine takes about ten seconds.

Two small capsules

Take them together with a meal, or split morning and evening. Whatever you will actually stick with.

Any time, every day

Consistency matters more than timing. Many people anchor it to breakfast or dinner so it becomes automatic.

One bottle, 45 days

90 vegan capsules per bottle. No powders to mix, no fridge, no mess. It travels in a bag pocket.

What to expect, honestly.

Adaptogens build gradually. Here is a realistic arc, not a promise.

Weeks 1 to 2

Usually subtle. Some people notice calmer evenings or an easier wind down first. Keep going; this stage is about consistency, not fireworks.

Weeks 4 to 6

This is where most people form their opinion. A steadier baseline through the day is the most common description we hear from customers.

Weeks 8 to 12

The habit is doing its quiet work alongside your sleep and routines. This is the window the 90 day guarantee is built around, so you can judge the full arc.

Individual results vary. If little changes for you after a fair trial, use the guarantee. Keep the bottle.
