SUNNA SUPPLEMENTS Vitamin D3 & K2 60's (150ml White)

What the brand says

The type of Vitamin K2 in the supplement you choose also matters. The best form of Vitamin K2 is MK-7 because it’s highly bioavailable, however, many brands opt to use MK-4 because it’s a cheaper alternative, but studies have shown that this type of Vitamin K2 is poorly absorbed and has a shorter lifespan in the body. This means that in order to see results with MK-4, you would need to take several doses 2-3 times per day. On the other hand, one serving of our D3 & K2 MK-7 can be taken once daily and is very well absorbed into the bloodstream.
