Key Differences

Carnitine

L-Carnitine is a conditionally essential amino acid derivative synthesized from lysine and methionine. It is critical for transporting long-chain fatty acids into mitochondria for beta-oxidation (energy production). It also removes toxic acyl-CoA metabolites and has neuroprotective properties. ALCAR (acetyl-L-carnitine) crosses the blood-brain barrier.

Muscle GainFat Loss

Common Forms:

  • • Carnipure® (80% bioavailability)
  • • L-Carnitine L-Tartrate (80% bioavailability)
  • • Acetyl-L-Carnitine (75% bioavailability)

Glutamine

L-Glutamine is the most abundant amino acid in the body and conditionally essential during stress, illness, or intense exercise. It is the primary fuel for enterocytes (gut lining cells) and lymphocytes. Depletion during catabolic states impairs immune function and gut barrier integrity. Critical for recovery.
