The reviewed labels show that liquid Comprehensive Core and Core capsules are different formulations. The capsule panel lists its B3 entry as bioactive NADH at 5 mg; the dispensing-quart liquid panel lists niacinamide at 62 mg NE. These are different label declarations, not quantities that establish which format works better.
What exactly do the labels say?
| Reviewed Core format | Full serving | B3 entry as shown |
|---|---|---|
| Capsules | 4 capsules | B3 niacin as bioactive NADH — 5 mg |
| Dispensing-quart liquid | 1 fl oz | B3 niacin as niacinamide — 62 mg NE |
Keeping the wording intact matters. The capsule panel expresses its entry differently from the liquid’s niacin-equivalent declaration. Those numbers cannot be used as a potency ratio or a direct niacin-equivalent comparison. [P1][P2]
“NE” means niacin equivalents, a unit used to express niacin intake. It does not describe a measured rise in blood NAD levels. [N]
What are niacinamide and NADH?
Niacinamide, also called nicotinamide, is a form of niacin, or vitamin B3. NAD is a coenzyme involved in cellular reactions; NADH is its reduced form. These names describe related biochemistry, but they do not make two supplement preparations interchangeable. [N][H]
NIH explains that the body uses niacin to make NAD and that this coenzyme participates in energy metabolism and other processes. That biological role helps explain the terminology. It does not establish the comparative effects of these two finished Core formulas. [N]
Why did the manufacturer choose different forms?
The panels document the difference, but they do not explain the manufacturer’s formulation rationale. A specific explanation about stability, manufacturing or delivery would need manufacturer confirmation. We can describe the observed difference without supplying an unverified reason.
If that detail affects your choice, ask MEL which current formula and label revision apply to your bottle, how the capsule B3 declaration should be interpreted nutritionally, and whether it has a direct comparison of the finished formats.
How should this affect your buying decision?
Choose between formats using the whole formula and the serving routine you can follow consistently. If your question concerns a specific niacin intake, ask the manufacturer to clarify the capsule declaration before treating it as equivalent to the liquid’s niacin-equivalent amount.
Questions about the B3 comparison
Does 62 divided by 5 show that the liquid is stronger? No. That would compare differently expressed declarations as though they measured identical preparations and effects.
Does NADH on the label establish an anti-aging outcome? The ingredient name alone does not establish a finished-product outcome.
Where can I compare other format differences? Review the Core formula guide with the current manufacturer panels beside it.
