Promix L-Carnitine

Your body already makes L-Carnitine to transport fat into your cells for energy. But when you're crushing long rides, logging high mileage, or stacking hard training blocks, your natural supply can't keep pace with demand. That's where Promix L-Carnitine delivers.

This unflavored powder gives you 2,000mg of pure L-Carnitine per serving—the exact amount research shows can shift your metabolism to burn more fat and spare precious muscle glycogen during endurance efforts. Translation: you go longer before hitting the wall.

Power Your Endurance 

Clean Fuel – L-Carnitine shuttles long-chain fatty acids directly into your mitochondria where they're converted to ATP. More fat burned means your glycogen stores last deeper into your session.

Faster Lactate Clearance – Studies on endurance athletes show L-Carnitine reduces lactate accumulation at higher intensities, pushing back that burning sensation when you're riding at threshold or racing hard.

Accelerated Recovery – The same mechanism that helps fuel your training also speeds post-exercise recovery by reducing exercise-induced muscle damage and oxidative stress.

The science is straightforward: L-Carnitine acts as both a shuttle and a buffer. It moves fatty acids where they need to go while helping manage the metabolic byproducts that accumulate during intense training. Athletes who supplement consistently see improvements in fat oxidation, lactate threshold, and time to exhaustion.

How to Use L-Carnitine

Daily Loading: Mix 1 scoop (2,000mg) in 8-12oz water or your pre-workout drink. Take it 30-60 minutes before training.

With Carbs: Pair with carbohydrates to enhance absorption—add it to your morning oatmeal shake or pre-ride fuel.

Long-Term: Research shows the best results come from consistent use over 12+ weeks as your muscles gradually increase carnitine stores.

This isn't a quick fix. This is metabolic optimization for athletes who train with purpose and need their fuel systems firing at full capacity.
