One of the most common questions consumers have about NAD+ boosting vitamin supplement Nicotinamide Riboside “NR” (FAQs) (Reviews) is whether to take it with or without food. Here’s what NAD+ expert Dr. Charles Brenner (FAQs) has said:

In response to a question on Twitter (X):

QUESTION:

Hello!

Do you recommend taking it first thing in the morning before food or later in a day?

Also, are there any benefits of taking more that 300mg pill a day?

DR. CHARLES BRENNER:

“Most ppl (people) take NR first thing, with or without food.

There are dose-dependent increases in NAD.

Quite a lot of therapeutic trials are at 1-2 grams per day.

At higher doses, it makes some sense to split into 2 doses per day”
