Australia is tightening regulations on vitamin B6 supplements due to reports linking high doses to neuropathy, with stricter rules and increased awareness needed globally, as high doses can cause significant nerve damage even from over-the-counter products.
Dermatologist Dr. Charles Puza warns that high doses of vitamin B6 and B12, commonly found in multivitamins and supplements, can cause or worsen acne by affecting the bacteria on the skin. Many supplements contain doses far above the recommended intake, leading to potential side effects such as skin problems. Research has shown that these vitamins can alter the DNA of acne bacteria and help them thrive, potentially leading to breakouts and skin lesions.
ZMA supplements, which contain zinc, magnesium, and vitamin B6, are marketed as enhancing physical performance in athletes, but there is limited research to support these claims. While zinc, magnesium, and vitamin B6 individually have important roles in the body, the overall health benefits of ZMA are still unclear. Some studies suggest that zinc and magnesium may improve physical fitness, but results are mixed. Zinc supports the immune system, magnesium aids in energy production, and vitamin B6 supports brain health. Possible side effects of ZMA include nausea, diarrhea, and ataxia. More research is needed to determine the safety, effectiveness, and appropriate dosage of ZMA. It is recommended to consult with a healthcare professional before using ZMA or any other dietary supplement.
