Although a common mistaken belief is that glutathione is not well absorbed when its taken orally, significant data confirms that glutathione is efficiently absorbed across the intestinal epithelium by a specific uptake system
Targeted metabolism combined with immune checkpoint PD-1/PD-L1 inhibitors can block inhibitory signal transmission between tumor cells and T cells to relieve the functional inhibition imposed by tumors on T cells, restore the recognition and killing functions of T cells to tumor cells, and reactivate the immune response of T cells
