How much biotin can you take?

Hi Ladies. I've read where many of you are taking biotin for thinning hair. Just curious, how much can you take? And what happens if it's too much? Thanks so much for your input :)

Hi, I was taking 5000 mcg of Biotin for probably more years than I should have. Yes, it helped my nails and hair. But last year, doctor had me have some bloodwork done just to get my levels. I was feeling ok, but he wanted some taken.

Long story short, my thyroid levels were off, but I had no symptoms of any problems. According to the doc, he said I was hyperthyroid according to the levels. I have a friend with that, but she didn't see any signs of me having it either.

I ended up having a thyroid uptake scan done and it came back ok, thankfully. Even the person doing the scan asked why I was having it done. I did some research online and found the taking 5000 mcg of Biotin can make your Tsh levels and T3 level show false positive results.

I found the info on the Mayo Clinic's website and the doctor they referred me to had no knowledge of it.

Good luck with your decision.

I have taken 10,000 mcg a day for approximately 10 years with no side effects. It is a water soluable "B" vitamin, and any excess your body doesn't need gets "flushed" out.

I dont think the FDA has established a max for Biotin, but I have read no more than 10,000 mcg daily. I take 7500.

I saw an expensive derm who specializes in hair loss after I lost a tremendous amount of hair from using Wen. He prescribed 5,000 mcg, which I continue to take as a preventive.

ETA: I also "assumed" that this would be a safe vitamin to take as it's supposed to be water soluble. However, I just did a quick google and there is some concern to be had regarding overdose. Biotin levels should be checked periodically. I'm going to research some more.

I've been taking about 3000 to 4000 a day for about 3 years. Any info you find and could post on this would be greatly appreciated My derm never really discussed the use of biotin. Thanks.

redspa and others,

This is getting really weird for me. I have a story to tell. First off, here is just one link about the potential adverse effects of too much biotin:

http://www.livestrong.com/article/285340-side-effects-of-a-large-dose-of-biotin/

Now, my story . . .

I've been taking 5,000 mcg for about 6 months now and my hair is definitely growing back after using Wen. Only in the past year or two, I've been having, for lack of a better term, "psychic" types of experiences. I've only discussed it with my mom, who said that my paternal grandmother had this "gift."

I've been taking several vitamins and supplements for most of my adult life and place them in a 7-day pill sorter. I have to be careful when sorting because my glucosamine sulfate capsules are identical to the biotin capsules. Since I have started taking biotin, my pill box has fallen out of the cupboard about 3 or 4 times, spilling everything. This has resulted in my tossing all the identical-looking glucosamines and biotins. I then placed the pill box in what I thought was a safer place. Yesterday, somehow, when placing a box of tinfoil in the kitchen cupboard, it knocked out the pill box once again. I threw away all the glucosamines and biotins. I said to my husband, "I think someone is trying to tell me to stop taking this stuff." (meaning the biotin, specifically, because I had been taking everything else for years).

The article that I provided the link for (above), talks about eosinophilic pleuropericardial effusion, a potentially life-threatening condition. Five years ago, I had an episode of pericarditis (inflammation of the lining of the heart), which the cardiologist said was most likely due to a virus. It began with my feeling profoundly weak and tired through my whole body. I could barely lift myself up or walk at the time. Last week, I felt profoundly weak through my entire body and thought it was pericarditis again. I feel a little better this week, but still tired. I don't know anything about eosinophilic pleuropericardial effusion and pericarditis, but it seems to me that the symptoms would be very similar.

COULD IT BE THE BIOTIN? ARE MY PSYCHIC ABILITIES AT WORK TRYING TO WARN ME ABOUT THE BIOTIN?? Spooky stuff for sure. {#emotions_dlg.scared} I will continue to research and think I will cut down to every other day for the biotin.

I am providing a website for everyone to read about what I posted above. It also speaks to what CalicoGirl posted about. Hope this helps.

Hi,

I was told to take no more than 1000 mcg. per day. I now take it every other day, as my nails were getting too hard. It didn't do anything for my "thinning" hair.

I have used 5,ooo mcgs as per my dermatologists script. I took it for 3-6 months then stopped. I found it help with speeding the growing cycle of my hair (due to some hair loss after using Wen) and also bonus my nails looked awesome.

You know Andrew Lessman who sells vitamins on HSN knows everything about vitamins. His company is amazing. I take his vitamins.

I was taking an additional supplement to the Lessman, Hair, Skin and Nails. Then I decided there was enough in that plus my regular vitamin. So I don't take the additional supplement anymore. You have to be very careful with supplements as they are not regulated by the FDA.

I would have to go back and check AL's website but I thought his biotin had sulphur in it which I am allergic to.

I went with a different brand where it wasn't listed but didn't notice any difference.

Calico, pills are marked with numbers and or letters, you should be able to differentiate between your biotin and your glucosamine -

Thanks, mj. That's the first thing I looked for. There is nothing at all visible to my 3x readers. The next time I go to GNC, I will ask them.
