In 2017, the FDA published a safety alert to raise awareness that the supplement biotin can “significantly interfere with certain lab tests and cause incorrect test results…” This alert also states that there has been “an increase in the number of reported adverse events” (injuries associated with medical care) related to biotin interference with lab tests.
With the growing trend of more biotin supplement users in the millions (for hair and nails), labs were alerted to the increased risk of test interference.
But most doctors don’t take the time to ask patients if they are taking a supplement with biotin before blood tests and most patients don’t know to tell providers.
The recommended daily intake of Biotin is set by the Department of Agriculture at 30 mcg (0.03 mg) per day. Still, doses all the way to to 10,000 mcg (10 mg) have been allowed since there are ‘apparently’ no adverse effects. No long term studies have been done.
No “Apparent” Biotin Side Effects, But …
Biotin, a water-soluble B vitamin, interferes with the following lab tests:
- Troponin (the test for heart attack). Biotin can cause a false negative troponin indicating the patient’s heart is normal, when in fact they’ve had a heart attack!
- T4, T3, and Thyroid Stimulating Hormone (TSH)
- Beta human chorionic gonadotropin (beta–hCG) (it may well tell you you’re not pregnant)
- Vitamin B12
- Vitamin D
- Prostate-specific antigen (PSA)
Example: In thyroid lab tests, biotin supplementation can make you look more hyperthyroid than you really are. If this happens, then your doctor may lower your thyroid med in order to compensate – and you may end up feeling worse! The supplement does not impact thyroid function – it just interferes with the lab results. You can solve the problem by avoiding biotin intake for 3 days to be safe before tests. (source)
And You Can Overdose and End Up with… Hair Loss?
Extreme adverse reactions are rare. One person who took biotin in combination with vitamin B5 for two months developed eosinophilic pleuropericardial effusion, a life-threatening disease.
Can you imagine going in for blood tests and getting false lab results that lead to missed diagnoses with potentially serious consequences? Consider the harm to heart attack patients following a falsely low troponin assay. (source) Or diabetic patients with falsely low insulin levels.
I impulsively purchased this popular hair and nail product and was so disappointed to see that it had ingredients I don’t want in my body (titanium dioxide, mica, carmine color) and an atrocious amount of biotin. I ignored my own conviction to be a good label reader!
Remember, biotin might be hidden in your multivitamin, dietary supplement, or prenatal vitamin formula.
I Found Something Better Than Biotin For My Hair and Nails
I stopped my own radical hair loss from advanced Lyme years ago with this nano-zeolite (I recommend this chelator for deep cellular whole-body cleansing).
And now instead of taking biotin for hair growth support, I use this amazing homeopathic hair growth combo, and my hair is far stronger and thicker than normal for someone 71 years-old. I’m thrilled.
The bottom line: Always tell your doctor if you’re taking biotin. And remember, you are getting sufficient amounts in these commonly eaten foods:
[Btw, it’s my opinion that the FDA (and agencies like it) are doing a terrible job protecting consumers. The FDA turned a blind eye to falsely diagnosed ‘Covid’ when using a fraudulent PCR test they ran at 44 cycles. That fraud sent many people to the hospital that didn’t need to go there, and many wrongly got put on ventilators and ultimately died. They have also never taken incredibly harmful, chemo-like antibiotic Cipro or other black box drugs off the market. It only takes 1 incident to ruin your health or take a life.
I’m encouraging you and your precious family to be use extreme discernment and wisdom whenever you interact with the allopathic medical system or big pharma – medicines, doctor’s offices, hospitals, well-baby visits included.
“So, whether you eat or drink, or whatever you do, do all to the glory of God.” ~1 Corinthians 10:31
