KICK INTO KETOSIS: Ketones supplements can help you get into a ketogenic state quicker. The beta-hydroxybutyrate (BHB) formula helps support raised blood ketone levels. This helps with achieving ketosis quicker, as well as sustaining it. Sustained ketosis can in turn lead to healthy weight management.
FASTING SUPPORT: Our keto powder also supports intermittent fasting. Its formulated to provide you with the ketones and electrolytes you need to feel full for longer. This can help to reduce hunger levels, so you can extend your fast.
SWEET, NOT BITTER: We used monk fruit to give the perfect balance of sweetness and eliminated the usual bitterness of BHB salts. Our strawberry lemonade flavored exogenous ketones supplement mixes well and tastes delicious in water, shakes, and more.
BODY FUEL: Mornings, afternoon slumps, before workouts, for focus, maintaining high energy levels, and to reduce keto-adaptation symptoms. Exogenous ketones act as fat fuel for your keto lifestyle.
