Biotin and Hypothyroidism

Are you hypothyroid? Are you taking Biotin? You might want to talk to your doctor ASAP.

My doctor and I discovered an issue with biotin supplements and I felt like I needed to share my experience. He now asks all his patients who are on levo/synthroid if they take this vitamin.

If you have good TSH numbers but still feel terrible and are taking biotin please keep reading.

I have been meaning to post this for about a year. While this is old new for me I thought it might be helpful for someone else.

In my case I am on levothroxine .75 mcg and cytomel 5 mcg. At the time of the following lab work I was taking the following vitamins, too:

  • Vitamin C
  • Biotin
  • Selenium
  • Glucosamine and chondroitin
  • B-12

My friend suggested I was taking too many vitamins and to have a sit down with my doctor, so I did. I emailed him my list of vitamins before hand and h printed out all the medical info on the above vitamins for our appointment.

This is when we both discovered that BIOTIN can give false low TSH numbers. Yes. You read that correctly.

Like many hypothyroid patients I was taking the biotin to “help” with my thinning hair and eyebrows.

He had me stop taking biotin for a month and retest.

I went from TSH 1.4 to TSH 8.1!

We couldn’t believe it. He had me double the cytomel (now two 5 mcg pills) and retest in a few weeks.

Here’s what I was taking. Max strength 10,000 mcg per pill (I was taking 1 a day for about 6 months). My doctor ok’d this over the phone but he didn’t ask what strength and I didn’t know that was important.

Please, please if your numbers look “normal” but you still feel bad and you take Biotin please consider talking to your doctor, stopping Biotin, then retesting after 1 month.

YMMV, but it might make a big difference for you. It has for me.

Sources: I can not find the article that my doctor printed off his his own database, but try googling these phrases:

  1. biotin interference on tsh and free thyroid hormone measurement.
  2. Biotin TSH
  3. which revealed that biotin may interfere with the most commonly used thyrotropin and thyroid hormone assays. “

The above article tests the impact on children so the dosages mentioned are for a child. Still, by looking at the numbers we can still see how it could impact an adult.

Biotin dosage on the test subjects: “2 to 15 mg per kilogram of body weight per day) [more] than the dietary reference intake in children (5 to 25 μg per kilogram per day)” because of inherited metabolic diseases they had.

Now that I am no longer taking biotin:

  • I can now wake up at/around 8 when before I could barely crawl out of bed at 10.
  • I am not feeling motivated to run/jog again yet, but I am able to take a walk or use my rowing machine 1- 3 times a week.
  • I have experienced no weight loss, but I do feel better than I did when I was taking the biotin.

 

Overall, My TSH went from 1.4, to 8.1 after Biotin was removed, then back down to 0.71 on after Cytomel was upped to 10 mg a day.

It’s worth asking your doctor about it if you take biotin.

Remember- the only person who truly knows your body is you, and you’re also your best advocate. So, arm yourself with information, take good notes about your symptoms and stay optimistic!

Skincare and Makeup for Thyroid Patients/Super Dry Skin-Product Test

I’m on a mission to find the most hydrating medium-to-full coverage makeup for extremely dry skin…starting with drugstore brands.

If you’re in the same situation as I am I hope you’ll join me on this journey and let me know what has worked for you!

 

About me:

2 years ago I was diagnosed with thyroid cancer and had my entire thyroid removed.

My life has been turned upside down ever since.

I once had normal skin texture with no redness,  hair that didn’t fall out, no dry scalp, and a body that responded to exercise and diet with the appropriate response (weight loss/muscle gain).

Those days are over, apparently… and 2 years later I’m just now starting to come to terms with it.

Lately  I noticed that my skin looked awful in cosplay photos- it was dull, dry, and made me look way older than I really am.

This made me seek out some new information and help on how to choose makeup that isn’t a heavily advertised Japanese BB cream.

I needed something that matched my skin tone and moisturized my now desert-like skin.

I’ll warn you- these images could be disturbing to those who have an aversion to dryness!

About the photos:

  • All applications are on a clean face with PCA moisturizer and Maybelline Baby Skin pore eraser primer underneath.
  • No undereye concealer except for the Skinfood that I had on hand. It’s the wrong color- I’m kinda new to this whole “color correcting” thing.
  • Photos are taken with my iPhone 6s using the “daylight” setting on my vanity mirror. They looked much more clear before posting them here..not sure what happened there.

A quick rundown of my situation:

  • Super mega crazy dry
  • Cool pale/classic ivory
  • Slight redness mainly on cheeks, chin, and nostrils
  • Current mood: embarrassed and frustrated. Thyroid skin is such a hassle!

Skincare:

First things first. I needed a good skincare routine.

Seeing as I never had skin problems before and always just bought whatever the Clinique rep recommended (a generic, normal skin regimen) I had no idea where to start.

At first I was getting regular facials. I thought that was the first step. However, even with the hydrating facials I was left dry.

Then I went to the Korean district of Tokyo and blindly bought whatever the salesperson recommended.

He recommended sensitive skin products  without touching my skin. From a distance it still looks normal, so as you can imagine this was a total fail when I got home.

The only silver lining was that the kit included one of those super soft face brushes. I sold my failed skincare locally and moved on.

Then I bought a trial kit of PCA’s dry skincare products.

So far I’ve been able to stick with it, but I feel that there’s got to be a more moisturizing brand out there. If you have a suggestion, please comment! 

Makeup- the hunt begins:

Earlier I mentioned that my face is now dry. Unless you have a thyroid problem (hypothyroid, hashimotos, no thyroid, etc) then you may just be thinking “winter skin” level dry. Think again.

I am quite sure that my daily dryness is worse than the average person’s worst winter dryness day.

I started researching and found a few leads. I live on a remote military base with very limited products, so unfortunately some of the best suggestions online were nowhere to be found.

I did find a few to test, though.

Potato quality iPhone photos incoming…

1. Maybelline Dream Velvet Soft Matte Hydrating foundation

Maybelline Dream Velvet Soft Matte Hydrating foundation

The general rule of thumb based on my research is that if you have dry skin that you want to avoid a matte base because it will make your skin look dull and more dry. I found this to be true, but this was marketed as “hydrating foundation” so I decided to give it a try.

These are my notes from the application: 

 *Doesn’t blend well with dense brush

* Sits on the really dry places

* Feels nice overall, light and doesn’t feel tight

* Lasted about 2 hours before I felt like it got a dull, matte look (it was a soft-matte, after all, so I wasn’t surprised).

Verdict: Changed to Toss

 

2. Covergirl + Olay Facelift Effect Firming Makeup
My Notes:

*Exfoliated

Covergirl + Olay Facelift Effect Firming Makeup

*Same blending issue- doesn’t take the dense brush well.

*Used fair tone, might be a shade too light

*Doesn’t seem to cover redness or take the translucent powder under my eyes very well.

*Rubs off when I blow my nose , sweats off

*This felt dry and cakey to me

Verdict: Toss

 

3. Neutrogena Nourishing Long Wear Makeup with tone correcting complex

 My Notes: 

Neutrogena Nourishing Long Wear Makeup with tone correcting complex

*Blends somewhat with the dense brush. Had to finish with finger tips.

*Feels nice overall, light and doesn’t feel tight

*Kind of deals with my redness

*Has a seriously matte finish, though

*Most expensive of all the foundations I bought

Verdict: Toss

 

 

 

 

 

4. Covergirl + Olay Simply Ageless 3 in 1 

I got frustrated and thought I was maybe imagining the redness I kept seeing so I did a half and half makeup comparison.

My Notes:

My right: Neutrogena Nourishing Long Wear Makeup with tone correcting complex My left: Covergirl + Olay Simply Ageless 3 in 1

*Half and half CG+Olay Simply ageless (my left) and Neutrogena (on my right)

*Hard to tell since I’m new to this whole makeup thing, but seems to look more hydrated/shiny/dewy compared to the other side.

*I liked the feeling of the CG, so I’m going to try it again with my new Spackle primer.

*It seems to have more unfavorable chemicals than I’d prefer

Update: tried it with the Spackle primer. Nice and dewy at first, but I felt a change after about an hour or 2. I’m going to give it a go today and see how it does. It’s not tight or flaky..yet.

Update 2: I didn’t realize it at first, but this is a scented product. The third time I tried it I didn’t use any of the other skincare items I was using before because I suspected they caused the tingly redness on my cheeks. Nope, this product made my cheeks kind of tingly and red all by itself.

Verdict: Changed to Toss

 

 

5. Covergirl CG Smoothers

My Notes:

Covergirl CG Smoothers

*Didn’t blend very well with brush. finished with hands.

*Dried really matte, feels dry, but not as dry as Neutrogena.

*Doesn’t help with tone evening, cheeks still red even before adding blush

 

Verdict: Toss

 

 


 

Here’s a few I want to try. They’re unavailable in my area, though, so I’m going to try to find them on Amazon.

Wishlist: 

  • Maybelline Dream Smooth Mousse- I have tried this since this post and it’s kinda awesome- I’ll update this post later with photos and a review. 
  • Maybelline Dream Satin Liquid
  • L’Oreal True Match Lumi- I have also tried this. I feel it’s so-so, but still a keeper. I’m not a fan of the N1-2 shade, it’s kind of dark on me. I’ll update later on this, too. 
  • MAC Face & Body
