I used Kenetik. From a formulation standpoint, they use bioidentical D-beta-hydroxybutyrate, which results in higher ketone levels than a ketone salt or something like 1,3-butanediol, and is a heck of a lot tastier and cheaper than a ketone monoester.

Nick's 24-hour ketone experiment.
4.4 mmol/L in a day: the ketone level a water fast takes about a week to reach.
Nick Norwitz, MD, PhD, combined a ketogenic diet, a 24-hour fast and two servings of Kenetik. Individual results vary.
How Nick ran it.
Pair a ketogenic base with timed Kenetik servings. This is Nick's own protocol, shared for education.
-
Set your base
A ketogenic day, around 60 to 80% fat, weighted toward unsaturated fats like olive oil.
-
Time your servings
One to two Kenetik Shots, 10 grams of D-BHB each, late in a 24-hour fasting window. Nick took his near the 19- and 23-hour marks.
-
Hold the habit
Between protocol days, a daily Kenetik Can keeps ketones in a light range.
Not medical advice. Talk to your doctor before starting a fast.
Not all exogenous ketones are created equal
Where Kenetik lands on the things that matter: ketone form, ketone level and cost.
| Kenetik | Ketone monoester | Ketone salts | 1,3-butanediol | |
|---|---|---|---|---|
| Ketone form | Bioidentical D-BHB + R-1,3-butanediol | Ester | Salt | Diol |
| Ketone level | High | High | Low | Moderate |
| Cost per serving | $$ | $$$$ | $$ | $$$ |
