Full Spectrum Vitamin KTM is a comprehensive vitamin K formula containing three forms of vitamin K, as well as representative forms of the other fat soluble vitamins, vitamins A and D, and vitamin E as gamma and delta tocotrienols. Vitamin D and K are particularly typical deficiencies, due to inadequate sun exposure (vitamin D) and low amounts in the diet (both). The delta and gamma tocotrienols are many times stronger than delta and gamma tocopherols, as antioxidants and in relationship to their varied functions.
