Are you using niacin or nicotinamide riboside? If so, watch this video! These supplements can help you age more gracefully and give you more energy, but they can also hurt your liver, mess with your neurotransmitters and your mood, and even sap your energy.

In this video I discuss using a powder for better control over the dose, and how to match your niacin dose to a corresponding dose of trimethylglycine (TMG).

The nicotinamide riboside powder can be found at hpnsupplements.com.

The TMG can be found at https://chrismasterjohnphd.com/tmg.
