Fairfield Nutrition Thoughts
KE4 is a liquid ketone ester in a 60 mL bottle, sweetened with allulose and organic stevia. It requires refrigeration after opening and has a distinctive taste that many users dilute with water. The 5 mL capful format makes it straightforward to measure smaller serves without additional equipment.
Why This Formulation / How It Works
KE4 is a liquid beverage containing D-Beta Hydroxybutyrate / D 1,3 Butanediol Monoester as the main ingredient at 30 g per 60 mL bottle. It also contains water, allulose, taurine (0.5 g), organic stevia, natural flavours, and potassium sorbate as a preservative. The bottle cap measures 5 mL, allowing the contents to be divided into smaller serves without a separate measuring tool.
How to Use
Each 60 mL bottle contains one capful (5 mL) as the smallest measurable unit. A typical daily amount is 10 mL (two capfuls); the full 60 mL bottle is a single larger serve. Pour the measured amount into a small glass or measuring tube and dilute approximately 1:1 with water before consuming. Build up the amount gradually from a smaller starting serve.
