Rutaecarpine

What Does Rutaecarpine Do?

Rutaecarpine is a bioactive alkaloid extracted from the Evodia rutaecarpa fruit, traditionally used in Chinese medicine. In the context of a pre-workout, it serves a dual purpose: acting as a vasodilator to enhance blood flow and as a metabolic regulator for stimulants.

• Endothelial Nitric Oxide Release: It stimulates the release of nitric oxide in the blood vessels, which helps relax the smooth muscle tissue and increases diameter for a better pump.
• Caffeine Metabolism: It is a potent inducer of the CYP1A2 enzyme, which accelerates the breakdown of caffeine, helping you avoid the 'wired' feeling long after your workout ends.
• Vasodilation: By reducing vascular resistance, it ensures that oxygen and nutrients are delivered more efficiently to working muscle tissues.
• Anti-Thrombotic Effects: It may inhibit platelet aggregation, further improving the fluidity of blood flow during intense physical exertion.

Clinical vs. Gym Bro Dosing

Key Insight: If your goal is the 'pump,' 100mg is the sweet spot. However, if you are using it to help you sleep after a late-night session, ensure you take it toward the end of your workout to avoid neutralizing your pre-workout stimulants too early.

Side Effects & Warnings

• Diminished Stimulant Response: The most common 'side effect' is that it works too well at clearing caffeine, which can lead to a premature energy crash if taken too early.
• Gastrointestinal Distress: Some individuals may experience mild stomach cramping or nausea at higher dosages.
• Liver Enzyme Induction: Because it significantly ramps up CYP1A2 activity, it can interfere with the half-life of various prescription medications.

Contraindications: Do not use rutaecarpine if you are taking medications metabolized by the liver without consulting a physician. It is best used by those who train in the evening and need to wind down quickly.
