Experts Warn of Dangerous Vitamin Supplements Sold Online

Experts have raised alarms over vitamin and mineral supplements sold online that contain dangerously high levels of nutrients, sometimes exceeding recommended limits by up to 12.5 times. A recent investigation conducted by Which? identified these products on major platforms including Amazon, eBay, Superdrug Marketplace, and TikTok Shop.

The findings highlight serious health risks associated with excessive intake of certain vitamins and minerals. According to Sue Davies, head of food policy at Which?, the availability of supplements containing potentially harmful doses is “shocking.” She emphasized that consuming more than the advised amounts can lead to severe side effects, including liver damage and weakened bones.

Investigation Findings on Unsafe Supplements

Which? based its assessment on guidelines from the NHS and a report from the UK’s Expert Group on Vitamins and Minerals. The focus was on four specific supplements known for their risk: vitamins A, B6, D3, and zinc. The research revealed alarming doses, such as a product from AliExpress containing 1,250μg of vitamin D3, which is 12.5 times the recommended daily limit of 100μg. High levels of vitamin D can lead to elevated calcium in the blood, causing symptoms like vomiting, confusion, weak bones, and even kidney failure.

While high doses of vitamin D can be used to treat deficiencies, they should only be administered under medical supervision for short periods. Other supplements identified included “Growth” and “Height Growth Maximiser” products from the brand Pslalae, available on Temu, which contained 62.5μg of vitamin D3. Additionally, B6 supplements were found in doses ten times higher than recommended limits, while some vitamin A products exceeded safe levels by five times. Certain zinc supplements were also reported to contain twice the advised amount.

Calls for Stricter Regulations and Responses from Companies

In light of these findings, Which? is advocating for improved regulation and oversight of online marketplaces and supplement manufacturers. Ms. Davies stated, “Better regulation and oversight of the supplements industry is desperately needed so that consumers are not put at risk by regularly consuming products which contain more than the advised safe upper levels.”

In response to the investigation, AliExpress asserted that it prioritizes product safety and noted that non-compliant products are promptly removed. A representative stated, “The platform has effective prevention and control strategies in place.” Amazon responded by emphasizing that it requires all products in its store to adhere to applicable regulations, while acknowledging ongoing discussions regarding what the appropriate guidance should be.

eBay expressed its commitment to ensuring compliance with its policies and relevant laws, adding that the limits set by the NHS and the Food Standards Agency are advisory. Superdrug confirmed that it prioritizes customer health and has removed flagged products. Temu stated it complies with UK laws regarding food supplements, asserting that listings found to violate these regulations will be reviewed and removed swiftly. TikTok Shop reiterated that unauthorized or banned substances are prohibited from being sold on its platform and confirmed the removal of flagged listings.

As consumers increasingly turn to online platforms for health supplements, the need for stringent regulations becomes more critical to safeguard public health.
