D3 Liquid is cholecalciferol derived from lanolin and provided in a liquid base of sunflower oil and purified water. In this liquid formula, vitamin D and sunflower oil are combined using a special micro-emulsification process designed to create a natural micellized matrix which, when coated by the stomach bile, will encourage absorption.*
Great product and it worked!
This product is actually prescribed to my dog to maintain his liver health. He's been on it for a year with great results
