NAD+ & Vitamin B12

What is in the pen?

NAD+ is not a peptide but a dinucleotide coenzyme present in every living cell, cycling between oxidised (NAD+) and reduced (NADH) forms to carry electrons in metabolism. Its levels decline with age in many tissues, which has made it and its precursors a major research topic. Cyanocobalamin is the stable synthetic form of vitamin B12, a cofactor for methionine synthase and therefore for methylation chemistry. The pen supplies both in one lot-tracked research format.

What is NAD+ studied for in research?

• Ageing and metabolism. A 2025 *Nature Aging* review surveys strategies, applications and challenges of targeting NAD+ [1].
• NAD+ precursors. The biology and studied potential of NMN and NR as NAD+ intermediates is reviewed in *Cell Metabolism* [2].
• Adipose and insulin-resistance models. NAD+ biology in adipose tissue has been reviewed from mechanism to therapeutic hypotheses [3].
• Reproductive and ocular models. Examples of the breadth of current NAD+ research include ovarian-function [4] and ocular-disease [5] studies.

Laboratory and review findings only — not claims of human effect.

Specifications and documentation

The COA reports identity and quantity for NAD+ and cyanocobalamin separately. Both components are light-sensitive: keep the pen refrigerated, in its carton, capped between uses. How to read the COA →
