What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Nicotinamide riboside is researched for its role in boosting NAD+ levels to support cellular energy, though human evidence remains limited. Schizandra fruit extract is traditionally used for liver support and stress adaptation with moderate evidence for antioxidant properties. Overall, clinical evidence for this specific combination is minimal.

Formulation Notes

NR (Nicotinamide Riboside) is made in the human body, but production declines dramatically as we age. NR is a precursor to NAD+, a vital molecule that supports metabolic functions as well as klotho and sirtuin production and expression, which in turn harmonize external and internal environment. QuintessenceNR is made with organically grown Schizandra berries from Changbai Mountain, Manchuria. Called "the quintessence of tonic herbs," it is traditionally believed to benefit all organs in the human body. This is the ultimate (quintessential) adaptogenic formulation.
