this vitamin is the best choice we did for our daughter. Her Vitamin D3 level were low and we have been recommended by NBN company to try this vitamin D3 , within a month the level increased up to 52 mg , we were so happy to learn about that. Will Keep giving our daughter and I recommend everyone looking for good quality of vitamin D3 to choose this supplement for its best quality. Thank you NBN

Research shows the people with multiple sclerosis should increase their daily Vit. D intake. This is what I take!!! I haven't had a relapse in over 2 years and I am not on MS Rx drugs. Thank you Lori and Dr. Shaw for creating a line of fantastic supplements.
