Yes, methylene blue is FDA-approved, but only for specific uses. It’s officially greenlit to treat acquired methemoglobinemia, a rare blood disorder where hemoglobin can’t properly carry oxygen due to chemical or drug exposure (e.g., from dapsone or benzocaine). The FDA has approved formulations like ProvayBlue (5 mg/mL) and Methylene Blue Injection, USP (10 mg/mL) for this purpose, administered intravenously under medical supervision. It works by converting methemoglobin back to functional hemoglobin, restoring oxygen delivery.

That’s the extent of its FDA blessing. Other uses—like vasoplegic syndrome, cyanide poisoning, or off-label buzz like anti-aging, cognitive boosts, or skin health—aren’t FDA-approved. Those lean on its mitochondrial and antioxidant properties (boosting ATP, cutting ROS), but evidence is thin, and the FDA hasn’t signed off.

Methylene blue turns your urine blue because it’s a dye your body pees out mostly unchanged. Your kidneys filter it, and since it’s water-soluble and stays blue in urine’s pH, you get a colorful flush. Higher doses mean brighter blue, it’s totally safe, just funky. Gone in a day or two after you stop consuming it.
