I've begun to carry some D3 without K2 because some people are on blood thinners and can not tolerate the K2!

D3 5000 contains vitamin D3 (cholecalciferol) in convenient softgels. Vitamin D3 is the bioidentical form of vitamin D synthesized in the body from cholesterol, following activation by the UV rays in sunlight. This form is excellent for maintaining healthy levels of vitamin D in the body. Mounting evidence suggests roles for vitamin D not only in bone health, but also in supporting immune, neurological, musculoskeletal, cellular, and cardiovascular health
