Vitamin D and K.

We spend far too much time indoors and not exercising.

You are correct, my FRiend.

Without sufficient vitamin D, your bod's chemical messengers put calcium in arteries rather than bones.

(Info very googlable.)

Even bigger than D and K, I think it’s magnesium.

People don’t drink groundwater anymore... something like 80% of Americans are deficient in magnesium.

And no magnesium means bad or absent calcium utilization.

Yes, D3 and K2

I have a friend who has osteoporosis. She started taking K2 with her calcium and had a huge increase in her bone density. Over 10% in one year. She had never had an increase before.

Sorry… I forgot the K2!
