White blood cells (WBCs) comprise many different cell types, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Neutrophils, lymphocytes, and monocytes account for ~99% of WBCs, and accordingly, in the video I propose optimal ranges for these cell types in terms of health and longevity.

Circulating levels of white blood cells (WBCs) are one of the 10 variables used to quantify biological age with PhenoAge (https://michaellustgarten.com/2019/09/09/quantifying-biological-age). The reference range for WBCs is 4.5 – 11 *10^9 cells/L, but within that range, what’s optimal? Several studies have reported that WBCs greater than 5 are associated with […]
