NAD Price Ledger

How we review

This site and Vivacelle, one of the NAD+ supplements we cover, share an owner. When we link to other products, we may earn a commission if you buy. We publish the price, serving and label figures each product states, so you can check our numbers against the source.

We read each product page and record what it states, product by product, pack by pack, on the date shown on every review.

We work out the price per serving from the price and the servings count the page states. Where the page states its own per-serving figure, we show that figure and say that the page stated it.

Anything a page does not state is marked as not stated. We do not estimate missing doses, servings or prices.
