Start your fasting routine with Kētos Core. Trusted by biohackers and wellness gurus alike, Core is clinically calibrated to support clean, healthy ketosis.
Power-up your fast. Core is engineered to help you feel your best and leanest by optimizing your physiology during the fasted state. Seven active ingredients work together to target your metabolic architecture, supply the essential co-factors required to fuel ketolytic energy production, and modulate the biological stress response to hunger to support you to achieve your fasting goals.
- Drive healthy cellular energy production with Dimagnesium Malate and high-dose Thiamine (B1), essential substrates that fuel the Krebs cycle to prevent fasting fatigue.
- Modulate serotonergic signaling with Affron® (saffron) to help minimize sugar cravings and stabilize mood during caloric restriction.
- Elevate cognition via a 1:1 ratio of L-Theanine and Rhodiola Rosea, promoting Alpha brainwave production while mitigating cortisol spikes.
- Support healthy insulin sensitivity and glucose metabolism with clinical-grade Chromium Picolinate — a trace mineral essential for maintaining steady energy levels.
- Maintain cellular hydration and prevent neuromuscular fatigue with bioavailable Potassium and Magnesium electrolytes.
Core contains two targeted complexes that combine seven active ingredients to synergistically to optimize fasting physiology:
- Cognition Complex (400mg) A synergistic pairing of L-Theanine and Rhodiola Rosea (Standardized SHR-5) designed to induce "Flow State." This blend works to modulate the HPA axis, mitigating the cortisol spike often associated with fasting, while promoting Alpha brainwave production—the neurological signature of calm, razor-sharp focus.
- Metabolic Complex (30mg) & Energy Matrix Features affron®, an ultra-premium standardized Saffron extract that targets serotonergic pathways to help minimize sugar cravings at the neurological level. This is supported by Thiamine, Dimagnesium Malate, and Chromium, which drive the Krebs cycle for efficient ATP production and maintain healthy insulin sensitivity in the absence of food.
- Vegetarian, vegan, gluten-free, nut-free, and contains no artificial colors or flavors.
