How it works
How Kenetik fuels your brain
Kenetik gives your brain ketones, a fuel it already knows how to burn. Here's how it works.

Most of that energy comes from glucose. During a long fast, your liver turns fat into ketones and your brain switches over to burn them as its main fuel (Owen 1967; Cahill 2006).
Kenetik delivers that fuel in a drink. Ketone drinks raise blood ketones without a fast (Stubbs 2017).
Caffeine masks tiredness. Ketones add fuel.
Caffeine covers up the signal that you're tired. Ketones give your brain more fuel to work with.

| Stimulant | Yes. Caffeine is a central nervous system stimulant. Source: Fredholm 1999 | No. Kenetik is caffeine-free and not a stimulant. |

| How long it lingers | A half-life of around 5 hours that varies widely between people. In one study, caffeine taken 6 hours before bed still disrupted sleep. Sources: Nehlig 2018; Drake 2013 | No caffeine in any serving, so it adds none to your evening. |

The ketone your body already makes
Kenetik is made with bioidentical D-BHB, the same ketone your body produces during fasting, sleep, and sustained exercise.
No ketone salts, so no L-BHB, the form your body doesn't make.

- 12 gof ketones in every can
- Caffeine-freeNot a stimulant
- Informed SportCertified
Questions, answered.
Is Kenetik a stimulant?
No. Kenetik is caffeine-free. Instead of blocking the signals of tiredness the way caffeine does (Fredholm 1999), it gives your brain ketones to burn as fuel.
Do I need to be on a keto diet?
No. Kenetik gives you ketones directly, so you don't need to fast or change your diet. Ketone drinks raise blood ketones even after a meal, though a meal lowers the peak (Stubbs 2017).
Can I have Kenetik with coffee?
Yes. Kenetik has no caffeine, so it doesn't add to your caffeine intake.
What are ketones, exactly?
Ketones are molecules your liver makes from fat when glucose is scarce, such as during a fast or a long workout (Cahill 2006). The main one is D-beta-hydroxybutyrate, or D-BHB, which is what Kenetik delivers.
Feel it for yourself.
Clarity and focus on demand. 12 grams of ketones, caffeine-free, nothing artificial.
