Big-name companies, retailers, and social media platforms have pulled various supplements from their listings following a safety investigation. A study by Which? revealed that some supplements on online marketplaces contain up to 12.5 times the recommended safe upper limit of popular vitamins and minerals.
Consumer safety experts examined Vitamin D, Vitamin A, Vitamin B6, and Zinc supplements available for sale on platforms like AliExpress, Amazon, eBay, Superdrug, Temu, and TikTok Shop. For instance, while the NHS suggests a daily intake of 10 micrograms (µg) of Vitamin D, some platforms listed products like Nuke Nutrition 10,000 IU (250µg) vitamin D3 supplements for sale, exceeding safe limits.
Upon discovering concerns, Nuke Nutrition promptly removed the product from sale for further evaluation. Another alarming find was vitamin D3 supplements on AliExpress in 50,000 IU doses, equivalent to 1,250µg – significantly surpassing the recommended daily intake.
The excessive intake of certain vitamins and minerals can lead to serious health issues, as highlighted by the NHS. These supplements, if taken in high doses without medical supervision, can result in conditions like hypercalcaemia, which may lead to severe complications such as vomiting, confusion, bone weakening, and kidney failure.
Notably, Which? also identified Vitamin D supplements for children that contained much higher levels than the advised dose of 2,000 IU or 50µg for kids aged one to ten. For example, Temu featured Pslalae’s “Growth” and “Height Growth Maximiser” supplements marketed as suitable for various age groups, containing 2,500 IU (62.5µg) of vitamin D3.
While Vitamin A is essential for vision, immune system support, and skin health, exceeding the recommended daily intake of 1500µg can have adverse effects. Similarly, the excessive consumption of Vitamin B6 and Zinc beyond the advised limits can lead to health issues like copper deficiency, fatigue, and anaemia.
Concerned about public health, Which? emphasized the need for improved regulation in the supplements industry to prevent consumers from unwittingly consuming products with potentially harmful levels of vitamins and minerals.
Various companies responded to the findings, with actions ranging from product withdrawal to reassurance of compliance with regulations. The importance of adhering to safe dosage levels and seeking medical advice before high-dose supplementation was emphasized by the supplement brands in question.
In conclusion, the issue underscores the necessity for stringent oversight and regulation to safeguard consumers from the risks associated with excessive vitamin and mineral intake in supplement products.
