Fasting basics
Do Kētos products break a fast?
Why do I need specific supplementation while fasting?
Converting stored fat into clean fuel relies on specific cofactors. We include high-potency thiamine and chromium to support cellular energy production and help keep your blood sugar steady without food.
Fasting can also draw down catecholamines that help your brain focus, leading to brain fog and fatigue. CORE replenishes those pathways with L-Tyrosine and L-Theanine to keep you calm, motivated, and focused while you fast.
Fasting is a form of stress. Unlike standard vitamins, CORE includes a Metabolic and Cognition Complex featuring clinical doses of Rhodiola and Saffron. These targeted adaptogens help regulate healthy stress response and manage cravings, keeping you supported where willpower alone can fail.

What's in Core?
Metabolic Complex: designed to fuel the cellular machinery of fasting, curb cravings and fortify physiological resilience:
Saffron Extract (Satiereal®): an ultra-premium, clinically studied extract that targets the psychological friction of fasting. Satiereal® works on serotonergic pathways to support mood and emotional balance, promoting steadiness-of-mind that keeps stress from steering you back toward food, reducing snacking cravings and making it easier to complete your fast.
Thiamine: an essential cofactor for metabolic flexibility, supporting the enzymes that allow your body to shift gears from burning sugar to burning fat, promoting an energized transition into ketosis and peak mental clarity.
Chromium: hunger pangs are often just blood sugar fluctuations in disguise. Chromium supports insulin sensitivity and healthy glucose metabolism, flattening the peaks and valleys of hunger for a smoother fasting experience.
Cognition Complex: designed to sustain focus and keep you calm under the demands of a fast:
L-Tyrosine: the direct precursor your brain uses to make its focus catecholamines (dopamine and norepinephrine). As a long fast draws those down, tyrosine helps replenish them, supporting sustained focus and cognitive flexibility when demand is high.
L-Theanine: promotes alpha-wave brain activity for elevated focus and clarity. Works synergistically with your morning coffee, smoothing out caffeine jitters to provide clean, sustained alertness throughout your fast.
SHR-5 Rhodiola: fasting is a hormetic stressor: positive stress that signals your body to adapt and grow. Rhodiola is the premier adaptogen that acts as a thermostat for this response, keeping cortisol balanced rather than spiking. We use the clinical SHR-5 extract to support deep resilience.

What is the rice hull for?
When and how should I take CORE?
Extended Fasts (24 Hours+ / OMAD): the priority is maintaining homeostasis and cognitive function. We recommend taking 2 capsules in the morning with at least 12oz of water. To sustain performance during longer windows, you may take two additional capsules in the early afternoon (before 3 PM).
The Daily Intermittent Faster (16:8 or 18:6): to extend your overnight fast until lunch, take 2 capsules in the morning with at least 12oz of water. This hydrates you early and introduces the Metabolic Complex to stabilize morning glucose signaling, while the saffron minimizes the 10am hunger wall.
