I find it infuriating that doctors aren’t telling patients that they need k2 to help their bones. My endocrinologist didn’t bother to mention it to me even after a blood test that showed my k levels were are the bottom end of the range. I learned about k2 approximately 2.5 yrs after I was diagnosed w/ osteoporosis. When I then ask my endocrinologist about k2, he was like oh yeah maybe you should supplement.

I’m currently taking Super Smart Complete K. One serving (1 capsule) contains 1500 mcg K1, 1000 mcg K2 MK 4, 150 mcg K2 MK7. I take 1 per day. I also take 1 Jarrow’s BoneUp capsule per day. 1 capsule is 1/2 a serving and contains 7.5 mcg K2 MK7.

According to the Calton’s https://caltonnutrition.com/meet-the-caltons/ Vitamin D3 and K compete for uptake and shouldn’t be taken together.

There is some vitamin D3 in the BoneUp supplement but I believe they balanced the vitamins and minerals to prevent “competition” in uptake/absorption.
