We were asked by a medical clinic that we work with to create a Vitamin D3 product in response to a growing need with their patients for Vitamin D. They have been seeing significant deficiencies in the tests they perform on patients and needed a high quality supplement from a reliable source... Healthy For Life! This product is not part of our regular "Essentials" program and we do not recommend it for everyone. If you have been tested and are known to be deficient in Vitamin D or are someone who is inside most of the day (Vitamin D is produced when the sun shines on your skin), this is a great supplement for you. As with all our products, we use organic ingredients when available. The ingredients in this product are Vitamin D3 disolved in organic sesame oil. 1 Drop = 1000IU, 300 Drops per bottle, 10 ml, take one or two drops per day or as directed by your health care provider.
