I have taken Life Extension Super K for years as well as 5000 - 10000 IUs of D3 a day, the higher amount in the winter when I am less exposed to sunlight. https://smile.amazon.com/Life-Extension-Super-Softgels-Vitamin/dp/B07TFBGDPH/ref=sr_1_43?crid=162S0EHL7YG6Q&keywords=k+vitamin+full+spectrum&qid=1577550663&sprefix=K+vitamin%2Caps%2C286&sr=8-43
Other natural sources of vitamin k2 are bone broth, grass fed beef, and dairy products made using milk from grass fed cows. I use Kerry Gold brand butter.
Both my parents suffered from heart disease, my father hardening of the arteries. I am a female, approaching age 70, and have no sign of arterial calcification or heart disease. My teeth are healthy and strong, my recent bone scan is good, and no sign of macular degeneration or cataracts in my eyes, which my parents had and my sister has now. I also take a trace mineral supplement. I attribute my good health to faithfully taking mineral and vitamin supplements, and cutting sugar and carbs out of my diet as much as possible. I also try to stick to organic foods as much as possible and stay away from seed oils.
