“I take NMN — typically 500 to 1000 milligrams in the morning. I want to be transparent that I take it based on the mechanistic logic and the animal data, knowing the human trials are still early. I'm treating this as a calculated bet, not a proven intervention.”
Huberman personally takes NMN at 500 to 1000 milligrams in the morning, based on mechanistic logic and animal data, acknowledging human trials are still early.
