A 2020 study found no additional benefit of 45mg vs. 5mg.

This study found that evidence for MK7 benefits is extremely limited.

As for the book you mentioned, I've never seen so many one-star reviews on Amazon- including several from physicians.

I doubt if any physicians would give any stars to books on osteoporosis treatment with K2. They would be prescribing bisphosphonates, etc... as my Dr. does. I don't follow that advice as I don't want disintegrating jawbone, femur snapping, etc... awful side effects that result in poor quality bone.
