02 Apr 2020 --- Vitamin K2’s significant role in reducing inflammation and boosting cardiovascular health has been identified by new research, endorsed by NattoPharma. Published in Nephrology Dialysis Transplantation, the paper examined the link between early vascular aging in chronic kidney disease (CKD), with a focus on the role of NattoPharma’s MenaQ7 vitamin K in counteracting oxidative stress and the aging process. The researchers note that the findings are a crucial step toward solidifying a reference daily intake (RDI) for vitamin K2.
