L-Carnitine Injectable — Supplements
Intramuscular L-carnitine for enhanced bioavailability and direct tissue delivery.
Overview
Injectable L-carnitine provides direct intramuscular delivery bypassing the low oral bioavailability (~15%) inherent to oral L-carnitine supplements. IM administration achieves significantly higher plasma and tissue carnitine levels, making it suitable for addressing carnitine insufficiency, supporting fat metabolism, and enhancing exercise recovery. It is particularly used in clinical settings for carnitine deficiency syndromes, dialysis patients, and in integrative medicine protocols for energy and body composition optimization.
Indications
- Carnitine insufficiency or deficiency
- Enhanced fat metabolism support
- Exercise recovery and performance
- Body composition optimization protocols
Mechanism of Action
IM injection bypasses first-pass metabolism and intestinal absorption limitations
