Experiences with

Biotin

I know biotin affects blood results for thyroid tests. Can I take Vit b supplements containing biotin during taking levothyroxine? Do i need to take biotin? What B vitamins are most important to take? Can anyone recommend a good brand with no fillers or crap in them? Thanks

It seems that opinions vary on how long before a thyroid blood test you should stop B vits with Biotin, it seems to vary from 2-7 days. I read somewhere the Biotin can lower or raise FT3.

Does the rule regarding avoiding biotin apply to all blood tests or just to thyroid test? Thank you

Will small amount of biotin skew lab tests? Hello, I have been on an eating program that involves several prepackaged a day since July. I was a bit worried how it might affect my thyroid because it has soy in it, but not a large amount.

Did it work for you hair growth?

Is five days enough or should I delay blood test for a couple of days to make it seven clear days of no biotin? Blood test appointments are easy to book. Thank you for your help.

Hello, I ordered some Biotin supplement after seeing it recommended here. I notice it contains zinc. I have seen somewhere that prednisolone can react with zinc. Is this correct please?

i have lost lot of hair despite taking Biotin. I am on 50 mcg of synthroid. Endo doesn’t think hair loss is due to thyroid.. Anyone else have hair loss issues?

website says folate and biotin can ( as we know) alter results. I have continued with folate and B12 but stopped B Complex. Is this ok? Confused!

Should I have followed the recommended protocol re time of day and thyroid/ biotin supplements for this test?

This was sent as advice from blue horizon, just thought it interesting them saying to stop biotin 8 hours prior to testing.

How long before labs to stop B Complex Solgar-50 which contains D-biotin 50mcg and does it make much difference. I suspect this question has been asked a Zillion times but on googling there are various answers from 2 days to a week thanks

how many days before a blood test do I need to stop a b complex that contains biotin? Is it just 2 days?

I’m aware that biotin can affect the results. Do I need to stop the super b complex prior to testing?

She now wants me to stop taking anything with biotin and have another blood test in 3 months.

hi again my doctor lowered my thyroxine from 200 mg to 150 mg that was 5 weeks ago I’ve also been taking high strength biotin with zinc and selenium for about a week but twice now my eyes have swelled on the lids and underneath very red and itchy could this possibly be the biotin I’m fed up was just

It was not done with my usual regime of an early appointment 9 am, and no biotin, but they are both within range so is there any point in repeating the test if my endocrinologist is happy with these? Thank you

I stopped my B-Complex and the extra Biotin that I take. Thank you so much .

The medichecks advice is to stop anything with biotin for 2 days, but B12 for a fortnight before testing - does that sound right? Anything else I should stop (along with B12 and a B complex, I'm also taking D+K2, magnesium and selenium)? many thanks

I already take 10,000 biotin once a day and 2 1200mg +D3 per day. Open to suggestions.
