In an effort to protect public health, Australia’s Therapeutic Goods Administration (TGA) has announced that vitamin B6 supplements with high doses will no longer be available for general sale starting in 2027. The move comes after increasing reports of nerve damage linked to long-term use of these high-dose supplements. So, what does this mean for consumers?
Why the Vitamin B6 Change Is Happening
Vitamin B6 is essential for various bodily functions, from brain health to protein metabolism. But, like anything, too much of a good thing can become harmful. The TGA’s decision follows an extensive review of vitamin B6 products, spurred by hundreds of reports of side effects like peripheral neuropathy—nerve damage that causes symptoms such as tingling, numbness, and pain, typically in the hands or feet. Many of these reports have come to light in recent years, leading to growing concern about the safety of high-dose B6 products.
It’s worth noting that the recommended daily intake of vitamin B6 for a healthy adult is between 1.3mg and 1.7mg, a far cry from the high doses in some supplements, which can contain over 200mg per dose. While the body can get rid of excess B6 to an extent, it doesn’t handle larger amounts well, leading to toxicity. Over time, this toxicity can accumulate, causing nerve damage and other health issues.
What Will Change for Consumers?
Starting in June 2027, any product with more than 50mg of B6 per recommended daily dose will be moved behind pharmacy counters, where it will be available only with the guidance of a pharmacist. Products containing more than 200mg of B6 per dose will continue to require a prescription. The shift allows the TGA to better regulate the sale of high-dose vitamin B6, aiming to limit unnecessary risks to consumers.
For those wondering about lower-dose products, don’t worry—vitamin B6 supplements with doses under 50mg will still be available for general sale. But the focus here is on ensuring that people who need higher doses for specific health reasons, such as those with deficiencies, are doing so under professional supervision.
Is Your Vitamin B6 Intake Safe?
If you’re currently using high-dose B6 supplements, it might be a good idea to pause and re-evaluate your use. Health experts suggest that the average Australian’s diet is typically sufficient in B6, thanks to a varied intake of fruits, vegetables, meats, and dairy. If you don’t have a specific deficiency diagnosed by a healthcare provider, chances are you don’t need a supplement at all.
Dietitian Dr. Evangeline Mantzioris explains that the growing availability and marketing of high-dose B6 products have led many consumers to believe they need supplements “just in case.” But in reality, unless there’s a proven deficiency, people should be cautious. She suggests checking the labels of any vitamin or supplement products you’re taking for B6 content and consulting with a doctor if you’re concerned.
What About the Risk of Harm?
The main concern with high-dose vitamin B6 is the risk of toxicity, which can lead to long-term nerve damage. While some individuals might experience side effects from low doses, the risks increase with prolonged or cumulative exposure. For instance, many energy drinks and protein powders contain added B6, which can contribute to higher-than-expected intake. This cumulative effect is often overlooked, but it’s one of the reasons the TGA is taking action.
If you’re experiencing symptoms like tingling, burning, or numbness, stop using B6 supplements immediately and speak with a healthcare professional. The sooner you stop taking the supplements, the more likely it is that symptoms will improve. However, if exposure continues, the damage could become permanent.
