user review for best overthe counter acetyl-l-carnitine Bronson Acetyl L-Carnitine 500 MG High Potency Amino Acid Non-GMO, 60 Capsules : Health & Household We Like Vitamins Acetyl L-Carnitine
Description
Carnitine is a non-essential amino acid that helps to maintain overall good health by facilitating the transfer of fatty acid groups in the mitochondrial membrane for cellular energy production

It should not be used in patients with trimethylaminuria (fish odor syndrome) or carnitine palmitoyltransferase II deficiency

Although both testosterone and carnitine improved symptoms of male aging, there was overall superior benefit to carnitine with no real side effects
