Vitamin D3: Made from the same kind of Vitamin D (cholecalciferol) that your body naturally produces when exposed to sunlight! Very few foods in nature contain vitamin D, and most D3 supplements are sourced from lanolin, the fat of a lamb’s wool — but the vitamin D in these drops is sourced from lichen, a vegan source of D3. Multiple Benefits: Support your kids immunity, bone strength, muscle function and energy levels with our vegan D3 liquid drops in a delicious orange flavor! D3 aids the body in absorbing Phosphorus and Calcium, supporting immune functions and bone health. Vegan Formula: Per Serving (15 Drops or 0.5 mL): 640 IU Vitamin D3 (as Cholecalciferol) Other Ingredients: Organic Olive Oil and Organic Orange Oil.
