Thorne puts out a K2 that is made in a lab. It is drops, and the drops last a long time. The caveat is that I actually went back to Carlson's 5mg pills, which are made from animal sources, because I didn't feel the Thorne product made me feel as well.
There are MK-7 K2 products, which actually come from bacteria. This has had a decent showing in some of the literature as actually helpful.
I have tried K1, and I once also had a supplement with a range of them, but I felt the K1, and K1 makes me feel weird. Theres a strange sort of electric sensation- my teeth feel weird, and it generally makes me feel out of sorts. I don't know what it is, but I have heard the body does a poor job converting K1. If you want to get your K from plants, eat plants. Hopefully there are cofactors in plants that could help with conversion.
