KE4 is not a salt, is naturally derived, 100% bioavailable, and is the only Ketone Ester that’s published FDA GRAS and Made in the USA. Contains no caffeine and no sugar. Ketogenic diet not required Taste Warning: Our "Very Scary Cherry" flavor improves upon the earlier "rocket fuel" taste, but it’s still rough and similar to cough syrup. If it's not to your liking, we suggest trying our Ketone Shot or our Ke4 that is sweetened with sucralose. Sucralose helps to block the bitter taste much better compared to the stevia versions. This is the lowest cost ketogenic drink to reach 1mm blood ketone levels. Recommended by Dr. Mary Newport in her latest book Complete Guide to Ketones, and mentioned in the book Ketones. The Fourth Fuel.
