Our mission is to help you enhance your fast by achieving better health through ketosis. This is why we offer the following benefits as part of our customer guarantee:

BACKED BY SCIENCE

Clinically Curated Formulas

There are endless supplements in the world. We prefer to offer fewer products that meet a higher standard. Kētos products are:

Intentionally curated
We don’t release a product unless we believe it fills a real need for fasters and people pursuing ketosis.

Mechanism-driven
Each product starts its life from “How does this fit into a fasted, ketogenic physiology?”

Built on evolving research
Our thinking is informed by current science on the metabolic process, fasting ketones, and insulin resistance. We update our perspective as the evidence evolves.

If we wouldn’t feel good using a product in our own fasts, we wouldn’t feel right putting the Kētos name on it.

PREMIUM SUPPORT FOR FASTERS

Personalized Guidance for Real-World Routines.

Fasting isn’t one-size-fits-all. Neither is Kētos. Our vision of support includes:

Education that respects your intelligence
Clear explanations of how fasting and ketosis work.

Protocol-aware guidance
Whether you follow 16:8, alternate-day fasting, keto cycles, or longer fasts, our content and tools are built to help you integrate Kētos intelligently.

Human-first communication
Straightforward, science-informed information so you can make better decisions and feel safe and secure while fasting.

We’re here to help you confidently gain control of your fast.

CLEAN-LABEL FORMULATIONS

Purity and Transparency Guaranteed.

Fasting is a high-trust practice. You’re intentionally changing when and how you eat. All Kētos products are designed to be fasting-compatible, so you can achieve your fasting goals with ease.

Built on a clean-label philosophy
Short, intelligible ingredient lists, each included for a clear purpose.

Free from unnecessary sugars and gimmicks
We avoid ingredients that undermine fasting or ketosis, like hidden sugars and hype-driven fillers.

Designed for real protocols
Our products are created with common fasting and ketosis strategies in mind.

Because of our long standing partnerships with the top scientists in the metabolic sciences, our supplements are best in class.

Our U.S. Based Team of Fasting Experts Has Your Back.
