Biotin & Lab Test Accuracy: The Most Important Safety Flag Here
Opti Core Pro's label includes 2,500 mcg of biotin per serving — a very high dose that the FDA has warned can interfere with certain laboratory test results.
Understanding this specific risk matters more than almost anything else on this label, especially if you may need blood work done.
What the FDA has warned about
The FDA has issued safety communications warning that biotin in dietary supplements can interfere with certain lab tests and cause incorrect results, including falsely low results with some troponin assays — tests commonly used to help diagnose heart attacks. Read the full FDA warning.
Why 2,500 mcg is a meaningfully high dose
Typical dietary biotin intake is measured in micrograms per day at levels far below this amount. Supplements formulated at high biotin doses are more likely to cause the kind of lab interference the FDA has flagged.
Applying this to Opti Core Pro
This is one of several safety considerations we flag in our full ingredient breakdown, alongside interaction warnings for Alfalfa, Saw Palmetto, Stinging Nettle, PABA and Fo-Ti.
