When Vitamins Turn into a Silent Threat

Australian health authorities have issued serious warnings about the uncontrolled use of vitamin B6 supplements, highlighting that excessive doses can cause severe damage to the nervous system instead of delivering the expected health benefits.

According to the Australian Broadcasting Corporation (ABC), numerous cases of neuropathy linked to the overuse of this supplement have recently been reported, particularly among women who take it to relieve pregnancy-related nausea or premenstrual symptoms, as it is available over the counter without a prescription.

Although vitamin B6 — also known as pyridoxine — plays a vital role in metabolism and neurotransmitter production, studies suggest that the body usually does not require additional supplementation. A balanced diet including meat, grains, vegetables, and fruits typically provides sufficient amounts of this vitamin.

Doctors warn that excessive intake may lead to “peripheral neuropathy,” a condition involving damage to nerves outside the brain and spinal cord, causing symptoms such as numbness, pain, and muscle weakness in the hands and feet.

In this regard, Professor Nial White from Macquarie University and Dr. Wesley Matthews from the University of Sydney explained that most affected patients in Australia showed improvement after discontinuing the supplement. However, some cases required long recovery periods ranging from several months to up to two years.

Experts strongly advise consulting a healthcare professional before taking any dietary supplements, especially when there is no confirmed deficiency of vitamin B6, to avoid unwanted complications.
