According to LabDoor, the best multivitamin is Super 2 Daily, produced by Carlson Labs. It is a softgel that includes vitamins A, C, D3, E, B6 and B12. It includes a number of minerals, as well.
LabDoor performed a study on 75 multivitamin supplements in the United States. The study measured levels of key vitamins, minerals, fatty acids and heavy metals in each multivitamin. It compared the claims on the labels to the actual tested content of each multivitamin. Carlson Labs Super 2 Daily ranked first in quality and sixteenth in value, rating overall best multivitamin. It passed the purity test for heavy metal content, ensuring that the product did not contain potentially harmful metals in concentrations greater than one part per million. As of 2014, a serving of two softgels costs 46 cents.
