OneSource is a brand of multivitamins with tailored formulas to meet the needs of different populations. It is available online and at Walmart stores.

They further indicated that multivitamins such as OneSource are ineffective in preventing diseases. The researchers concluded that multivitamins should not be used for chronic disease prevention because they have no clear benefit for well-nourished adults and may even be harmful.
Dr. Edgar Miller, a co-author of the study, told CBS News that people should focus instead on eating a balanced diet rich in fruits, vegetables, nuts and low-fat dairy instead of wasting their money on multivitamins.
