L-Carnitine fumarate | CAS: 90471-79-7 | Nutritional supplements

L-carnitine fumarate is a compound formed by the combination of L-carnitine and fumaric acid, commonly used in dietary supplements. Its main function is to promote fat metabolism, increase energy levels, and may assist in athletic performance. It works by helping fatty acids enter mitochondria for energy supply, but the effect varies from person to person and needs to be combined with diet and exercise.

Definition and core role

L-carnitine is a naturally occurring amino acid derivative in the human body, responsible for transporting long-chain fatty acids to mitochondria for oxidative degradation. The addition of fumaric acid can improve the stability and bioavailability of L-carnitine. Research has shown that L-carnitine fumarate may exert its effects through the following mechanisms:

1‌ . Accelerating fat metabolism: promoting the entry of fatty acids into mitochondria, reducing fat accumulation;

2. Enhance energy and endurance: increase energy production, delay exercise fatigue;

3. Antioxidant effect: Fumaric acid has the potential to scavenge free radicals and reduce oxidative damage.

Safety and side effects

The safety is relatively high at regular doses (usually recommended at 500-2000 milligrams per day), but excessive doses may cause nausea, diarrhea, or abnormal body odor;

1. Long term high-dose use may inhibit the synthesis of L-carnitine and form dependence;

2. Interaction with other supplements: For example, caffeine may enhance its excitatory effect, and attention should be paid to dose superposition.
