Amino Acid

L carnitine

L-carnitine participates in the carnitine shuttle, which transports long-chain fatty acids across the inner mitochondrial membrane. The body also produces it from lysine and methionine.

This transport process contributes to the normal use of fatty acids within cellular energy metabolism.

In everyday life, L-Carnitine helps move fatty acids into your cells' energy-producing machinery to support normal energy metabolism and active recovery.

Its contribution depends on ingredient form, quantity and the complete formulation.

Ingredient overview

What it is

L-carnitine participates in the carnitine shuttle, which transports long-chain fatty acids across the inner mitochondrial membrane. The body also produces it from lysine and methionine.

  • Scientific identity: L-Carnitine; chemistry: 3-hydroxy-4-N-trimethylaminobutyrate.
  • How it works: Made or absorbed: The body synthesises it from lysine and methionine; meat and dairy supply more, and oral absorption is relatively modest. Concentrated in muscle: Around ninety-five % of the body's carnitine is held in skeletal muscle.
  • Primary function: This transport process contributes to the normal use of fatty acids within cellular energy metabolism.
  • What it supports: L-Carnitine helps move fatty acids into your cells' energy-producing machinery to support normal energy metabolism and active recovery.
  • Important consideration: Its contribution depends on ingredient form, quantity and the complete formulation.

Formulation rationale

Why we use it

CARPEDIEM selected L-Carnitine for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: This transport process contributes to the normal use of fatty acids within cellular energy metabolism.
  • Used in: CARPEDIEM MultiMen and CARPEDIEM Men’s Daily Performance Stack.
  • Works alongside: L-Carnitine complements CoQ10, Taurine and Algal DHA (Omega-3) to support a more coordinated functional-nutrition approach.
  • Meaningful contribution: L-Carnitine helps move fatty acids into your cells' energy-producing machinery to support normal energy metabolism and active recovery. Contributes to metabolic processes that are particularly relevant within skeletal muscle.
  • Quality and scientific context: Its contribution depends on ingredient form, quantity and the complete formulation. 2 ingredient-specific studies are included because the research reports a relevant benefit.
