Always take your D3 vitamins with K2.
Is K2 named after the famous mountain?
Yes here’s what K2 does it takes the calcium in your system and pushes it directly into your bones. The reason you take K2 together with D3 is that the D3 helps the calcium absorb into your system then the K2 pushes it into your bones.
Older people should be taking K2 because it keeps calcium from getting into your arteries and clogging them up.
