Vitamin D3-5000: Vitamin D3-5000 is cholecalciferol made from lanolin derived cholesterol from the wool of sheep. Vitamin D3 is the kind your body produces which makes it more efficient in absorption. Vitamin D2 is not the kind the body produces. Therefore, it's less efficient and you use more. It's also usually cheaper. Vitamin D3-5000 is Kosher certified. One capsule provides Non-GMO Vitamin D3 5000 IU (125 mcg).
