Natural Factors Whole Earth & Sea Vitamin D3 is the bioactive form of vitamin D and is necessary for the efficient utilization of calcium, in turn helping to form and maintain strong bones and a healthy immune system. This Vitamin D is sourced from wild harvested lichen, the plant-based vitamin D in this formula is in the natural form (cholecalciferol) and is better absorbed and utilized by the body. The lichen vitamin D3 is harvested and extracted in a sustainable manner and carefully processed to ensure optimum purity and stability. Lichens are small, unique composite organisms formed by a symbiotic and closely interacting relationship between fungi and algae. This gives them unique attributes such as surviving in extreme climates and having the ability to grow and accumulate meaningful levels of useful nutrients, including vitamin D3. Lichens are like moss or small plants and can be found all over the world including extreme environments such as the Arctic and deserts.
