About Longevity Label Check

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.

Longevity Label Check exists because supplement labels are hard to compare: one brand counts a serving as one capsule, another as three, and doses hide behind proprietary blends. We lay the labels out side by side, line by line.

Then we do the arithmetic the labels skip. Our price-per-serving tool divides each product's price by the servings its own label states, so you can see what a daily habit actually costs before you buy.
