WONDERFUL LICHEN. Lichens are small unique plant species consisting of a symbiotic association of a fungus with an alga. 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 Cholecalciferol. ACTIVE FORM & HIGH ABSORPTION. Cholecalciferol is the active form of Vitamin D3, so it provides superior absorption compared to regular Vitamin D3. When taken directly in this format it works more quickly and can be delivered in lower concentrations. Vitamin D3 in liquid filled hard shell vegetarian capsule form is easy to swallow and convenient to take. Some research indicates that vitamin D3 in liquid filled capsule form is more highly bioavailable than powdered or tablet forms. VEGAN & VEGETARIAN SOURCE. Vitamin D3 derived from Lichen is the only vegan source of Vitamin D3. INLIFE Vegan Vitamin D3 supplement is an excellent combination of Lichen Extract Oil and Extra Virgin Cold Pressed Organic Coconut Oil. ACTIVATES THE IMMUNE SYSTEM. In general, vitamin D3 functions to activate the immune systems, improve immunity and increase circulation. Vitamin D3 helps enhance calcium absorption by regulating concentrations of calcium and phosphorus in the body to provide essential support for bones and teeth. Vitamin D3 (termed the 'sunshine vitamin') is the same biologically active form of Vitamin D you get from the sun's UVB rays. With this complex, you will get the benefits without the burn. QUALITY.
