Make sure the vitamin D supplement you take passed our test and is right for you!
Isn't your health worth it?

Vitamin D plays a critical role in bone health, and adequate vitamin D levels in the blood are associated with reduced risk of heart attack, high blood pressure, depression, rheumatoid arthritis, asthma, and even colds. But you must choose vitamin D supplements carefully if you want the best for you and your family.

Our tests found many quality supplements providing 400 IU to 5,000 IU of vitamin D, but we also found products which did not contain their claimed amounts of vitamin D: One contained too much vitamin D, and a children's product contained less than what was listed on the label.

We also tested combination vitamin D supplements for amounts of other key ingredients, such as calcium, vitamin K and magnesium. Tablets were tested to ensure they disintegrated properly to release their ingredients for absorption, and all supplements were tested for contamination with lead, arsenic and cadmium. 

You must be a ConsumerLab.com member to get the full test results and vitamin D quality ratings for vitamin D supplements including combination products with calcium, magnesium, and/or vitamin K. You'll also get vitamin D cost comparisons to help you find the right product at the best price -- some costing only 1 cent per day. You will get results for 42 vitamin D supplements: 21 selected for testing by ConsumerLab.com and 21 additional products that passed the same tests through CL's voluntary Quality Certification Program, as well as information about two supplements similar to ones that passed testing.
