Core

CORE is designed to be fasting-compatible. It contains no sugar, no added calories, and no protein/fat/carbs, just active micronutrients and botanical extracts in a vegetarian capsule.

No. Everything in Core is non-caloric and non-insulinogenic — micronutrients and botanical extracts that don't spike insulin or pull you out of the fasted state. The trace rice hull in the capsule sits far below the threshold that would trigger mTOR. Core supports your fast without interrupting autophagy.

Fasting creates a unique metabolic environment that generic multivitamins aren't designed to support.

As your insulin drops, your body flushes out water and essential electrolytes rapidly. CORE replenishes potassium and magnesium to help prevent the headaches and muscle cramps associated with this flush.

Converting fat into fuel requires specific cofactors. We include high-potency thiamine to support mitochondrial energy production efficiently during this transition.

Fasting is a form of stress. Unlike standard vitamins, CORE includes a Metabolic and Cognition Complex featuring Rhodiola and Saffron. These targeted adaptogens help regulate healthy stress response and manage cravings, keeping you supported where willpower alone can fail.

CORE is built as two complementary stacks designed to optimize the ketogenic state and help you achieve clean, healthy fasting with ease:

Metabolic Complex

Designed to fuel the cellular machinery of fasting and fortify physiological resilience.

Magnesium
This one of the central biohacks for energy. Malate acts as a spark plug in the Krebs Cycle, which is responsible for ATP energy production. Magnesium enhances muscle function and cellular energy, so you can feel your best throughout your fast.

Potassium
Fasting is a natural diuretic state, meaning the body flushes water and electrolytes rapidly. Potassium citrate is highly bioavailable and simultaneously alkalizing. It optimizes intracellular hydration and buffers acidity, which helps prevent the muscle cramps and heaviness that can affect the early stages of a fast.

Thiamine
We include Thiamine at high potency because it acts as an essential cofactor for metabolic flexibility. Thiamine supports enzymes that allow your body to shift gears from burning sugar to burning fat. The aim here is for thiamine to promote an energized transition into ketosis so you can more easily obtain peak mental clarity.

Organic Saffron Extract (Affron®)
An ultra-premium, clinically studied extract that aims to target the psychological friction of fasting. Affron works on serotonergic pathways to support mood and emotional balance by promoting steadiness-of-mind that keeps stress from steering you back toward food, helping to reduce snacking cravings and making it easier for you to successfully complete to your fast.

Chromium
Hunger pangs are often just blood sugar fluctuations in disguise. Chromium supports insulin sensitivity and healthy glucose metabolism. By stabilizing these levels, it helps flatten the peaks and valleys of hunger, providing a smoother fasting experience.

Cognition Complex

Designed to calm the nervous system and sharpen focus.

L-Theanine
Promotes alpha-wave brain activity, and helps achieve a state of elevated focus and clarity. Works synergistically with your morning coffee, smoothing out the caffeine jitters to provide clean, sustained alertness throughout your fast.

SHR-5 Rhodiola
Fasting is a hormetic stressor—the positive stress we aim to achieve through fasting signals to your body to adapt and grow. Rhodiola is the premier adaptogen that acts as a thermostat for this response, keeping your cortisol levels balanced rather than spiking. We use the clinical SHR-5 extract to support deep resilience, so you can feel your best throughout your fast, while maintaining the desired healthy stress response.

No. Core is completely caffeine- and stimulant-free. The L-theanine is there to pair with your morning coffee if you drink it, smoothing out the jitters, but Core works just as well on its own and won't leave you wired.

Yes—in fact, it is a strategic advantage. L-Theanine pairs synergistically with caffeine to create a powerful smart stack. Together they produce clean, directed energy while the electrolytes actively replenish key minerals. We are big coffee drinkers too and love coffee while we fast :)

To produce our capsules, we use the outer hull of organic rice, which is composed of insoluble fiber and natural silica, not the starchy endosperm used for energy. This material is non-glycemic and non-insulinogenic, meaning it is not metabolized as glucose and will not trigger an insulin response or inhibit autophagy. The amount present is negligible—trace quantities (milligrams)—far below the threshold required to stimulate an mTOR response or trigger insulin secretion.

The baseline protocol is to take two capsules each morning of your fast without food. Because CORE is formulated with water-soluble cofactors and chelated minerals, it offers maximum bioavailability even in the absence of dietary fat. It is the perfect first-thing-in-the-morning ritual.

Here's how to optimize that dosage for your specific fasting style:

Extended Fasts (24 Hours+ / OMAD)

For those doing fasting for a full day or more, the priority is maintaining electrolyte 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) to replenish depleted minerals.

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, so you can confidently reach your eating window with effortless discipline and food freedom.

The electrolyte and energy support (magnesium, potassium, thiamine) can help you feel steadier immediately, with fewer cramps, headaches and energy dips. The mood and stress benefits of Rhodiola and saffron build with consistent daily over time, the way botanical extracts tend to. Use during every fast for optimal results

Yes, Core is built for daily use as part of your fasting routine, and the doses are designed for ongoing use. Take it on your fasting mornings; on non-fasting days it's fine to take as well.

Core is made for healthy adults, and most people tolerate it well. That said, saffron and Rhodiola are biologically active botanicals, so if you take prescription medication, particularly antidepressants (SSRIs/MAOIs), blood thinners, or blood-pressure or blood-sugar medication, or you're pregnant or nursing, please check with your doctor first.

Absolutely. The same cofactors that support a fast (magnesium, potassium, thiamine, chromium) support a low-carb or keto lifestyle too. Fasting is where Core shines, but it isn't a requirement.

Yes, Core is vegan and vegetarian, in a plant-based (HPMC) capsule. It's gluten-free, nut-free, and made without artificial colors or flavors.

Core covers the two electrolytes most people under-replace — potassium and magnesium. Sodium is the one your body loses fastest on longer or sweatier fasts, and it's the easiest to top up with a pinch of quality salt in your water. Core plus a little salt has your electrolytes covered.
