The clinical trials and laboratory papers behind the assortment, with their original publication details below.

Oral precursor studies

For the opening result, start with Yoshino and colleagues on NMN and muscle insulin sensitivity: the participants were postmenopausal women with prediabetes. Yi and colleagues measured blood NAD+, walking and quality-of-life scores in healthy middle-aged adults. The NR trial by Conze and colleagues concerns blood NAD+ and tolerability in healthy overweight adults.

The review of human precursor evidence is especially useful on the gaps between individual findings and broader clinical claims.

Epitalon experiments and Epithalamin

The earlier Epithalon paper used human fetal fibroblasts in culture. The 2025 cell-line study distinguishes telomerase-related lengthening in normal cells from the largely ALT-related response in breast-cancer cell lines. The melatonin experiment used cultured rat pineal cells.

For the human survival association, the preparation was Epithalamin, alone or with thymalin. That observational follow-up and the cell experiments answer different questions. The Epitalon overview adds context about the compound and its incomplete characterization.
