The quality of these vitamins have been verified for me. Both of my children brought home bad colds from school and my husband and I avoided catching them even though we were the designated nose wipers. My mother came to visit while they still had runny noses and unfortunately she left with a cold. I now swear by these vitamins and the other Doctor’s Best vitamins I take daily.

For me, this has been easily absorbable and utilized by my body, despite having metabolic issues. I believe it does assist with prevention of some health issues, and helps in the use and processing of other vitamins and nutrients, as well as aiding in healing.
