K2 helps regulate where calcium gets deposited, like in the arteries, which helps prevent that to some degree. When you take AAS, HDL levels (good cholesterol transporters) tend to decrease and LDL (bad) levels elevate. This chronic skewing of elevated cholesterol promotes atherosclerosis, longterm hardening of the arteries. This causes a rise in blood pressure over years due to tighter pathways that destroys kidney function and promotes cardiovascular decline. And hardened plaque can break off and then clog the pipes, leading to strokes.
Reading some studies on Angiotensin Receptor Blockers (ARBs) the other week, especially Telmisartan, I noticed it has been found that of deaths associated with cardiovascular disease, FOUR out of five deaths (4/5) were found to have significant atherosclerosis. So it’s kind of the smoking gun for dying from any cardiovascular disease, which is probably the number one cause of disease deaths besides cancer.
TLDR: a cheap easy attempt at damage control/risk mitigation. It’s something that needs to start now, preventatively.
