Vitamin K2 (MK4 or MK7?)
For those supplementing with K2. Do you use MK4 or MK7 and where do you source from?
Most of the bulk suppliers do not seem to currently stock K. BP has a joint formula with calcium, K2 and D3, but I find the D3 a bit under-dosed. Or, would you require less D3 if combining with K2?
