High doses of vitamin B6 can cause nerve damage and numbness.\n<\/p>\n<p id=\"mntl-sc-block_4-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> This vitamin is present in foods such as nuts, chickpeas, fish, and fortified cereals, but it&#8217;s also an increasingly popular ingredient in supplements and energy drinks. In Australia, drug regulators have removed supplements with high levels of vitamin B6 from the market due to reports of toxicity.\n<\/p>\n<p>  High Doses of B6 in Supplements and Energy Drinks  <\/p>\n<p id=\"mntl-sc-block_7-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Most adults need 1.3 to 1.7 mg of vitamin B6 per day to <a class=\"recommendation-inline-link-ai\" href=\"https:\/\/www.verywellhealth.com\/b-vitamins-11782574\" link-destination-recommendation-ai=\"true\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">support metabolism and nerve function<\/a>. Slightly higher doses are unlikely to cause harm, and it&#8217;s hard to reach toxic levels from food alone.\n<\/p>\n<p id=\"mntl-sc-block_9-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Vitamin B6 toxicity is rare unless someone consumes about 20 times the recommended daily amount consistently, said <a href=\"https:\/\/www.medstarhealth.org\/doctors\/kelly-krisna-johnson-arbor-md\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Kelly Krisna Johnson-Arbor, MD<\/a>, a medical toxicologist at MedStar Georgetown University Hospital.\n<\/p>\n<p id=\"mntl-sc-block_11-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Many supplements and energy drinks market vitamin B6 as a way to boost energy and support the nervous system. Some B6 supplements may contain up to 100 mg of B6, while energy drinks often have as much as 40 mg per serving.\n<\/p>\n<p>  Too Much Vitamin B6 Can Damage Nerve Cells  <\/p>\n<p id=\"mntl-sc-block_16-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Taking high doses of B6 may cause numbness, a pins-and-needles sensation, or pain in your legs, impairing your ability to walk.\n<\/p>\n<p id=\"mntl-sc-block_18-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> \u201cBasically, it\u2019s toxic to nerve cells,\u201d Johnson-Arbor said.\n<\/p>\n<p id=\"mntl-sc-block_20-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> These symptoms are associated with more than 100 causes, not just vitamin B toxicity. If you do experience these symptoms, it is especially important to mention your B6 regimen to your healthcare provider because they might not initially think about B6 as the culprit, she added.\n<\/p>\n<p id=\"mntl-sc-block_22-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> The treatment for B6 toxicity is to stop taking the high-dose supplements. However, these symptoms don\u2019t always reverse right away.\n<\/p>\n<p id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> \u201cThere are many reports of people whose symptoms have gotten better after they stopped taking the high doses of B6, but there&#8217;s also a phenomenon called \u2018coasting,\u2019 where people stop taking the B6 but then their symptoms actually keep getting worse for a couple of weeks, until they slowly start to get better,\u201d Johnson-Arbor said.\n<\/p>\n<p>  Most People Can Get Enough B6 From Food Alone  <\/p>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Most people can <a class=\"recommendation-inline-link-ai\" href=\"https:\/\/www.verywellhealth.com\/vitamin-b-foods-8761104\" link-destination-recommendation-ai=\"true\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">get enough vitamin B6 through a balanced diet<\/a> and do not need a supplement. However, if you take a multivitamin or a standalone B6 supplement, check the label to see how much vitamin B6 it contains so you can track your total daily intake.\n<\/p>\n<p id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> If you consume &#8220;reasonable levels&#8221; of B6, you likely won&#8217;t have any issues besides some potential gastrointestinal upset, said <a href=\"https:\/\/phmtox.msu.edu\/people\/faculty\/alanjami\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Jamie Alan, RPh, PharmD, PhD<\/a>, an associate professor of pharmacology and toxicology at Michigan State University.\n<\/p>\n<p id=\"mntl-sc-block_31-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> &#8220;If you are experiencing the [neurological] symptoms, talk to your healthcare provider right away to see if you are experiencing a [B6] overload that&#8217;s causing the symptoms,&#8221; Alan said. &#8220;Because this is so rare, exploring other reasons for those symptoms is equally important.&#8221;\n<\/p>\n<p>Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
