When R-spondin 2 was added to explant cultures from wildtype mice, the number of outer hair cells decreased modestly, further indicating that R-spondin 2 has the opposite effect of -catenin activation in the developing cochlea and do not appear to potentiate canonical Wnt signaling to increase the number of hair cells (Jacques et al., 2012

Because B12 is water soluble, your body does not store it, so it needs to be replenished on a consistent basis

Once in the bloodstream, glutathione travels throughout the body, including the brain, heart, lungs, and muscle tissue, where it can assist your cells through its cleansing and protecting the skin texture by improving the overall quality of the skin
