Common Name(s): Acetyl carnitine,acetyl carnitine,mitochondrial anti-aging active,acetyl group donor energy booster
CAS Number: N/a
DESCRIPTION
What It Does: Provides acetyl groups for mitochondrial energy metabolism, supports fatty acid transport for ceramide biosynthesis, and reverses mitochondrial dysfunction associated with skin ageing โ improving skin cell energy output for collagen synthesis and barrier function.
Why It's Used: Mitochondrial dysfunction is a primary driver of skin ageing โ alcar is the only carnitine form that penetrates the inner mitochondrial membrane providing both the acetyl group (for energy) and the carnitine moiety (for fatty acid shuttle) simultaneously.
How It Works: Alcar โ acetyl-coa (tca cycle entry) + l-carnitine (fatty acid beta-oxidation shuttle). acetyl-coa: tca cycle โ nadh/fadhโ โ oxidative phosphorylation atp. separately, l-carnitine forms acylcarnitine with long-chain fatty acyl-coa enabling inner mitochondrial membrane transport for beta-oxidation โ additional nadh for atp. the dual mechanism provides 30-50% greater energy yield than carnitine alone.

SCIENTIFIC NOTE
Alcar crosses the blood-brain barrier as a neuroprotective compound โ its skin application for mitochondrial anti-aging follows the same mechanism, providing skin keratinocytes and fibroblasts the same mitochondrial functional support documented in neurological anti-aging research.
