Australia will remove high-dose vitamin B6 supplements from general retail sale under new rules introduced by the Therapeutic Goods Administration (TGA). The regulator has moved to strengthen safety controls after identifying risks of peripheral neuropathy, a form of nerve damage associated with long-term consumption of large doses of the vitamin.
Under the updated framework, supplements that contain up to 50 mg of vitamin B6 per recommended daily dose will remain available in supermarkets, pharmacies and other general retail outlets. Products delivering more than 50 mg but not exceeding 200 mg per day will be reclassified as pharmacist-only, requiring professional oversight at the point of sale. Formulations providing over 200 mg per day will be limited to prescription access.
The TGA cites evidence showing that prolonged intake of high levels of vitamin B6 can lead to sensory nerve problems, including tingling, numbness or burning sensations, which may become persistent if not addressed. Because vitamin B6 appears in many different supplements — including multivitamins and combination products. Consumers may unintentionally exceed safe levels when using multiple items simultaneously.
The new restrictions will come into effect on 1 June 2027, giving manufacturers and retailers time to update product labels and adjust distribution. The regulator notes that most people meet their B6 requirements through everyday diets, and that additional supplementation is generally unnecessary for the majority of the population.
Consumers are encouraged to check product labels and avoid high-dose vitamin B6 formulations unless recommended by a qualified health professional.
