Moreover, L-Carnitine supplementation has been shown to increase protein synthesis in muscle fiber and increased plasma levels of L-leucine, an essential amino acid for protein synthesis [16]
Serum B12 levels peak 12 hours post-injection and remain elevated for 710 days depending on dose and individual clearance rates
