Your fat-burning transporter: L-Carnitine is an amino acid derivative that acts as the shuttle system for fatty acids, transporting them across mitochondrial membranes where they're oxidized for energy. Without adequate L-carnitine, fat literally cannot enter your cellular furnaces to be burned—instead accumulating in tissue while you experience fatigue despite ample stored energy.
Why supplementation matters: Your body produces only 25% of needed L-carnitine, relying on diet for the rest. Modern diets, aging, and intense exercise deplete levels faster than they're replaced. The result? Stubborn fat that won't budge, muscles that fatigue quickly, and recovery that takes days instead of hours. Injectable L-carnitine achieves 100% bioavailability compared to 5-25% oral absorption, while completely avoiding the digestive upset and TMAO production that plague oral supplements. Within days, your mitochondria shift into overdrive, finally accessing and burning stored fat for sustained energy.
Clinical studies show an average of 2.9 lbs over 12 weeks. When combined with diet and exercise, results typically double or triple. Individual results vary based on starting point and adherence.
For exercise performance, inject 30-60 minutes before workouts. For general fat loss and energy, morning injections work best. Consistency matters more than exact timing.
No. L-carnitine works by improving how your body converts fat into energy at the cellular level. There's no jittery feeling or crash—just sustained natural energy.
Yes. Studies show safety with daily use up to 2g for several years without adverse effects. Many athletes and patients use it continuously for ongoing benefits.
While exercise significantly enhances results, studies show modest fat loss (1-2 lbs) even without exercise. L-carnitine works best as part of an active lifestyle.
L-carnitine primarily supports fat metabolism and energy, while acetyl-L-carnitine crosses the blood-brain barrier for cognitive benefits. We offer L-carnitine for metabolic support.
L-carnitine is generally safe with most medications. Caution is advised with blood thinners (may enhance effects) and thyroid medication (may reduce absorption).
Oral L-carnitine is partially converted by gut bacteria into TMAO, causing fishy odor and digestive upset. Injectable L-carnitine completely avoids the digestive system.
