Vitamin D Report

Labdoor analyzed 17 best-selling vitamin D supplements in the United States for vitamin D3 content and heavy metal contamination.

Fifteen of the sixteen products texted exceeded their claimed vitamin D3 content, averaging 26% over their stated label claims. 6 of the 19 products exceeded their label claims by greater than 40%.

Additionally, all products recorded at least 1000 IU vitamin D per serving, significantly above vitamin D’s 400 IU Daily Value (DV) and its 600 IU Recommended Dietary Allowance (RDA).

All supplements passed their heavy metals assays.
