Natural fuel,
supernatural results

Ketones are nature’s superfuel. When the body is pushed to its limits, we convert stored body fat into ketones for energy. HVMN Ketone Ester is the world’s only drinkable form of the exact D-BHB ketone produced naturally in the body2. This is the one you’ve heard about — the ketone ester.

For sport

  • HVMN Ketone Ester is most effective for endurance exercise lasting an hour or more
  • Drink one serving 30 minutes before exercise with usual pre-workout fuel (carbs, caffeine, etc.)
  • For extended endurance exercise (2+ hours), consume an additional serving every 1.5 - 2 hours with usual carbs

For cognition

  • Use in conjunction or in replacement of your coffee or tea, and expect a mental clarity distinct from a stimulant effect
  • Ketones cross the blood-brain barrier and serve as an efficient fuel source for neurons in the brain

For recovery

  • Drink one serving 30 minutes after exercise with normal post-workout nutrition (protein, carbs, etc.)

For fasting and diet

  • Elevate your ketone levels to equivalent to 5-10 days of fasting
  • Non-insulinogenic calorie source compatible with fasting and ketogenic diets
  • High fat diets convert fat into ketones; HVMN Ketone Ester provides ketones directly

Frequently asked questions

What’s the history behind the ketone ester?+

Oxford, NIH, and DARPA scientists led by Professor Kieran Clarke and Dr. Richard Veech invented the ketone ester in HVMN Ketone Ester under the 2003 DARPA “Metabolic Dominance” program to develop foods to enhance US soldier physical and cognitive performance.

HVMN exclusively licensed the patents in 2016 and worked (and continues to work) in close partnership with the original researchers to bring ketone ester to the world in 2018. All other “ketone esters” on the market are falsely advertising, selling adulterated product, and/or stealing intellectual property from the inventors.

HVMN Inc. and TΔS® are exclusive partners on creating HVMN Ketone Ester, a ΔG® ketone ester-based sports performance drink.

How does HVMN Ketone Ester work?+

HVMN Ketone Ester is the world’s first ketone ester drink. HVMN Ketone Ester contains no caffeine, no sugar—only pure, natural energy from ketones to help you reach peak performance.

Exogenous ketone esters allow the body to use both ketones and carbohydrates for fueling at the same time, not possible with any other nutritional strategy.

Why does HVMN Ketone Ester cost so much?+

HVMN Ketone Ester is a novel technology and is still very expensive to manufacture. We hope to bring down the cost per unit as more people buy and adopt HVMN Ketone Ester into their life. More production of HVMN Ketone allows us to get economy of scale.

Is HVMN Ketone Ester approved / certified for sporting use?+

Yes. HVMN Ketone Ester is a NSF Certified for Sport, compliant with World Anti-Doping Agency regulation and is regulated by the FDA as a food ingredient (GRAS).
