Harness the power of nature with our vegan, plant-based Whole Earth & Sea Vitamin D3 & K2 liquid. A single drop provides these two essential and complementary vitamins. Plant-based vitamin D is sustainably sourced from 100% non-GMO algae and carefully processed to ensure optimum purity and stability. It is in its natural form (cholecalciferol) which is better absorbed and utilized by the body. In addition, the bioactive and highly bioavailable MK-7 form of vitamin K is included for optimum absorption.
