Everything to know

Revive 75 is a 75-day mineral supplementation and lifestyle protocol built around five products that cover five different mineral delivery mechanisms. It's not a diet, a cleanse, or a calorie protocol. It's a system designed to rebuild your mineral foundation — the thing your energy, sleep, and mental clarity all depend on — from the moment you wake up to the last thing you do before bed.

You can start with one or two and still feel a difference. If you're choosing a first pair, mRelease before bed and mSalt in your morning water are the most immediately noticeable for most people. The full stack works better because each product covers a delivery mechanism the others don't — but the protocol meets you wherever you are.

Most supplements deliver one mineral, one form, one route. Revive 75 delivers magnesium in five different chemical forms — electrolyte, ionic, natural matrix, performance blend, and transdermal — continuously throughout your day. The same multi-form logic applies to zinc, calcium, potassium, and selenium. That's the difference between topping up and actually rebuilding.

Most people notice something in sleep first — usually within the first week of using mRelease before bed. Energy and afternoon crashes typically improve by week two to three. Mood and mental clarity tend to follow in weeks three to six. Day 75 is the full picture. Results vary depending on your starting point and how depleted you are going in.

In most cases, yes. These are food-based minerals rather than isolated high-dose supplements, which reduces the risk of interactions. If you're on prescription medications — particularly thyroid medications, blood pressure medications, or diuretics — check with your healthcare provider first. Iodine in mTrace is the most relevant consideration if you have a thyroid condition.

Because the food supply has changed. A University of Texas study found measurable mineral declines across 43 crops from 1950 to 1999 — including organic produce, which governs how food is grown, not the mineral density of the soil it's grown in. Add stress, caffeine, and screen time — all of which burn through mineral reserves — and you can eat perfectly and still be running low.

CORE (corebycrucialfour.com) is the digital side of the protocol — video modules, food guide, daily blueprint, journal prompts, and monthly live AMAs with Charles. It's included with every subscription and accessed separately after purchase. It's not required to use the products, but it's where the full context for the protocol lives. Members can also ask Charles directly about anything in the protocol.

Yes — membership is flexible. Pause or cancel anytime through your account with no fees. The Full Protocol subscription bills every 75 days. The Monthly membership bills every 25 days.

Magnesium chloride can cause a mild tingling on some people initially — this is normal and usually fades within a few applications as your levels begin to replenish. If you have sensitive skin, start with 4–5 sprays on your calves rather than the soles of your feet and build up gradually. If you experience persistent irritation, discontinue and contact us.

Please consult your healthcare provider before starting any new supplement protocol during pregnancy or breastfeeding. Iodine and selenium in mTrace have specific upper intake recommendations during pregnancy that depend on your existing diet and prenatal supplement use.
