I'm not sure there is what you can call a typical dosage but I can share I take 500 mg of Acetyl-L-Carnitine along with 100 mcg Vitamin K2 twice daily (morning and evening) along with 600 mg of na-R-ALA morning and evening and the other supplements included in the Protocol 525 - https://theprotocol525.com/wp-content/uploads/2020/09/Instructions_Introduction.pdf.
