Labdoor Tests 30 Best-Selling Vitamin C Supplements

Vitamin C Supplements

SOUTH SAN FRANCISCO, CA – November 17, 2015 – Labdoor, the supplement testing and rating service, announces that their new Vitamin C Rankings are now published online and ready to help consumers find the highest quality products on the market.

Vitamin C is the most popular single vitamin supplement worldwide. Still, an estimated 15% of the US population is vitamin C-deficient. This can negatively impact early brain development in infants of vitamin C-deficient mothers and impair efforts to prevent chronic diseases like obesity, hypertension, arthritis, and age-related macular degeneration. Scurvy, with symptoms of easy bruising and bleeding and joint and muscle pains, is also a concern at sufficiently low levels of vitamin C.

Labdoor tested 30 best-selling vitamin C products in the US using 150 chemical assays to determine what and how much of each ingredient was present, including levels of any heavy metal contamination.

Tested products contained anywhere from only 40% of their label claims to more than 2 times their label claims. 22 of the products had more vitamin C than they claimed. The lowest recorded value was less than the recommended dietary allowances (RDAs) for vitamin C needed to prevent vitamin C deficiency – 90 and 75 mg/day for adult men and women, respectively. The highest recorded value exceeded 2000 mg/serving, the maximum average daily vitamin C intake still considered to be safe for most people. Labdoor also determined that 4 products may have potentially harmful levels of inorganic arsenic, a reproductive toxin.

This new report from Labdoor is designed to help consumers find the best vitamin C supplements. Labdoor publishes the actual quantities of each product’s key active ingredients and potential contaminants on its website. “Quality” and “Value” rankings are also available to help consumers sort through and select products that interest them.

“It’s so hard to be certain that you’re buying a safe, effective dietary supplement. Labdoor is working to make it easier for people to find the best products for their health.” – Neil Thanedar, CEO of Labdoor.
