Our verdict
Tru Niagen has randomized human trials showing its ingredient raises NAD⁺, and costs about $39/month. Embody has no controlled outcome trials, costs $99/month, and claims to be scientifically proven. If you want evidence per dollar, this is not a close call — but Embody is the only one of the two that bypasses digestion, which is the argument you are actually paying for.
Scores and verdicts are computed from our published rubric, which does not read commercial status. Where one provider is a paid partner and the other is not, that changes the label on the card and nothing else.
Before you choose either
Ask both for the dose their monthly price buys — most providers in this category do not publish it, and without milligrams the prices are not comparable. Our cost-per-milligram calculator does the arithmetic once you have the numbers. And read what is known about safety — for injectable NAD⁺, less than you would hope.
