Comparisons / Betaine vs L-Citrulline
Compare mechanism, clinical dose, safety profile, and products containing each ingredient.
Overview
Betaine is usually chosen for Strength and power athletes, while L-Citrulline is often selected for Lifters seeking pump and endurance.
May enhance power output and muscle endurance. Supports methylation.
Clinical dose: 1500-2500 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Boosts nitric oxide, improves blood flow and muscle pumps, reduces fatigue
Clinical dose: 6-8 g
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Betaine
Pre-workout marketing focuses on power/strength gains. Evidence shows modest benefits for power at 2.5g/day after 2+ weeks. Not as effective as creatine for strength. Often under-dosed in pre-workouts. Legitimate metabolic benefits but overhyped for muscle building.
L-Citrulline
Marketing claims: "Insane pumps," "Nitric oxide explosion." Reality: Citrulline genuinely works for pumps and performance, but requires 6-8g. Most pre-workouts contain 1-3g — far below effective doses. "Citrulline malate" is only ~57% citrulline, so 8g provides ~4.5g actual citrulline. Check doses, not just presence on label.
