process for preparing a crystalline form of menaquinol, crystalline form of menaquinol, process for preparing a solid form of menaquinol, pharmaceutical or nutraceutical composition and use of the crystalline form of menaquinol

摘要

The present invention relates to solid forms of menaquinol and processes for obtaining them by chemical or enzymatic reduction of menaquinone. Such solid forms have high oxidation stability, which allows effective use of menaquinol in the most common formulations using vitamin K2.
