Tag: High biotin levels

According to the National Institutes of Health, there is no evidence that biotin is toxic in humans, even at high intakes. This is because biotin, a water-soluble B-vitamin, is readily excreted by the body when it is in excess. However, while the body itself cannot produce an overabundance of this vitamin, excessive intake from high-dose supplements can have notable consequences.

Excessive biotin is primarily excreted in urine, making true toxicity rare. However, the most significant consequence of high biotin levels is not toxicity but potentially dangerous interference with critical lab test results.
