Comparing NAD plus and NMN? Before looking at the price, check whether you are comparing a capsule, an infusion appointment or another formulation. NAD plus is a coenzyme involved in cellular metabolism. NMN is a precursor used in pathways that make NAD plus. NR is another precursor. The names describe related chemistry, not interchangeable servings. An oral product comes with a serving label. An infusion involves an appointment and a provider. An injectable formulation has its own requirements. Compare the method as well as the ingredient. For two oral products, divide the pack price by the labelled servings. For appointments, compare the assessment, administration and follow-up included. Those are different kinds of cost. Then check the outcome. A higher blood measurement does not automatically mean better everyday energy. Look for information about the actual goal and formulation you are considering. Save the ingredient, route, amount and complete price together. A milligram of one molecule or route cannot be treated as an equivalent amount of another. The full guide explains the formats, NR, and a worked price example. Use the comparison explorer to organise the options around your own question.
