The Health Sciences Authority (HSA) is advising companies to monitor consumer feedback on the risk of peripheral neuropathy associated with excessive vitamin B6 intake. The maximum allowable limit for vitamin B6 in health supplements is 100mg/day for adults, and concurrent intake of multiple health supplements can cause peripheral neuropathy. The underlying causes are unclear, but symptoms usually resolve upon discontinuing use. Companies should inform users of potential risks through labeling and monitor consumer feedback for potential adverse events. Companies should ensure their products comply with HSA guidelines, including the maximum limit for vitamins and minerals.
