Biotin and Thyroid

When you think of biotin, vitamin B7, what comes to mind? The hair, skin, and nails vitamin, right? Not so right. There is not good evidence that biotin supplements can improve the health of hair, skin, and nails unless extremely deficient. However, it is true that biotin, vitamin B7, is involved in producing keratin. You know… keratin treatments for beautiful hair? What if you could take a vitamin and have beautiful hair? Not exactly. I know thyroid patients are constantly trying to have fuller hair, but taking biotin is not likely the answer and help you are looking for.

Warning

Taking supplemental biotin can cause false lab reports. Biotin may either increase or decrease free T4, and can create false positives for thyroid antibody levels. Most of the time, labs come back with results like the patient has Graves’ disease, but that is incorrect due to the biotin supplement! Make sure to let your doctor know if you are taking a high dose biotin supplement when they draw your thyroid labs.

I never recommend supplementak biotin unless it happens to be in your B complex or multi already. If you are struggling with the health of your hair, skin, and nails, it oftens means your whole body needs nutrients! I tend to recommend a high quality B complex so that you get all the B vitamins in balance.*

*Talk to your doctor before starting a new supplement

Get Biotin from Food!

Foods that are excellent or very good sources of biotin:

  • Almond
  • Egg
  • Onion
  • Sweet potato
  • Oats (GF)
  • Tomato
  • Peanuts
  • Walnuts
  • Carrots
  • Salmon

One serving of almonds (1/4 cup) gives you half of your needs for the day! Funny thing is that I had not eaten almonds for about 2 years (due to sensitivities), and I had my biotin levels tested and they came back borderline low. I wonder if it was from lack of almond eating. Hah!
