The Science Behind My Dailys Supplements

We build products on research, not trends. Below is a clear, growing list of peer-reviewed studies that informed our formulas and quality standards. Every product is third-party tested for purity and potency.

Vitamin D3 + K2

D3 supports vitamin D status and immune function. K2 helps direct calcium to bones and away from arteries. Together they’re studied for bone strength and cardiovascular health markers.

NMN — Nicotinamide Mononucleotide

NMN is a direct precursor to NAD+, a coenzyme central to cellular energy and repair. Human trials show increases in NAD+ and metabolic changes after oral NMN.

Lion’s Mane — Hericium erinaceus

Lion’s Mane contains hericenones and erinacines — compounds studied for NGF support and cognition. Human trials suggest benefits for mild cognitive changes and mood.
