A search for “NAD 100 mg” can lead to two very different labels: an oral serving containing 100 mg, or a prescription marked 100 mg per milliliter. The first states an amount. The second states a concentration.
Read the words and units beside the number before comparing products. This guide uses public product examples to explain the distinction; an individual injection amount and schedule must come from the prescribing team.
The denominator matters: 100 mg per serving and 100 mg/mL describe different things. Neither alone selects a suitable treatment plan.
The three questions hidden in one number
Ask what molecule the product contains, how it is intended to be used, and what quantity the number describes. Direct NAD+ is different from 100 mg NR, even though NR can contribute to NAD production. A front-label “NAD support” claim may name the biological goal rather than the ingredient inside.
Then look for the denominator: per capsule, per serving, per milliliter, or per vial. A missing denominator makes a price or dose comparison incomplete.
A 100 mg oral serving: the Rho example
Rho’s public liquid NAD+ label identifies 100 mg per 4 mL serving. That is an oral product description, not an injection instruction. The bottle’s total volume and serving count answer a different question from the amount in one labeled serving.
Our Rho review examines the liposomal positioning. A delivery-system label does not establish that 100 mg swallowed produces the same exposure or result as 100 mg administered by another route.
A 100 mg/mL prescription description: the CoreAge example
CoreAge’s offer page describes an injectable preparation at 100 mg/mL in a 10 mL vial. This is a concentration and container description. It does not tell every reader what to inject, how frequently to use it, or how long an opened vial remains usable.
Use the actual dispensing label and contact the pharmacy if it differs from the advertisement. Do not translate a website example into syringe markings or substitute another provider’s concentration.
Why a small number is not a safety category
“Only 100 mg” leaves out route, formulation, patient circumstances, and the rest of the product. A small-looking mass cannot establish whether a sterile preparation was made appropriately. FDA’s NAD-related compounding notice concerns ingredient suitability and reported reactions, which cannot be resolved by choosing the smallest advertised number.
What a useful comparison should contain
Keep a short record with the ingredient name, route, labeled amount, serving or container size, and total price. For a prescription, add the clinician, pharmacy, and the actual instructions supplied to you. Compare within the same product type first.
If the question is whether a clinical route fits your goal, start with nasal spray versus injections, rather than assuming that matching milligrams makes two products equivalent.
