I have vertical ridges on many of my fingernails which causes them to split snd catch. It hurts and it's unsightly. Anyone have an effective solution? I know I should wear gloves to keep my hands away from the water. I don't use nail polish or get manicures. It appears that my diabetes and thyroid conditions could be causing this…have any of you taken supplements or changed your diet to cope with this?

After nearly 2 months on 5000 mcg of biotin per day, I have noticed that my fingernails are harder and the splits, while still there, are not as prevalent or severe. Thanks to all of you who suggested remedies and for the biotin suggestion in particular.

There is a product that I was told about by my podia. It is called No Miss it comes in a glass bottle and has a dropper with it. I was told to use it once a day so I did that every morning for 6 months and all of my ridges went away and my nails even grew and got stronger. It is a fungal medicine but it work and I did not have any fungal issues when doc told meto use it. The original bottle got from a Nail place in the mall and then I went on line and ordered it. http://WWW.NOMISS.COM they have different sizes of bottles you can buy as well. It is a lot cheaper ordering it from the web site than getting it at the nail places.

Dear Margo,
Thank you for the input. I've been using the Biotin, recommended earlier, for about a week now and will let you all know how that works out. I suspect it will take some time for the nail to grow out to see those results. The product you recommend could be a good alternative if I'm not happy with the biotin results. I suspect that the No Miss liquid probably works faster since it must be absorbed by the existing nail material. Something to explore too. I've always had soft, flexible nails but these ridges and the splitting are a pain. I appreciate everyone's feedback! Thanks again!

I too have diabetes and thyroid conditions. My doctor told me that the ridges on my nails was caused from all of the medications that I have to take for these conditions, as well as some other physical challenges. I try to keep clear nail polish on my nails to help keep them more protected. If I don't use the polish, then I have splits in the quicks near the cuticles at the top of the nail. This helps me. I take supplements along with the medications. These are to help with other problems too. The doctor recommended the supplements. You might discuss this with your doctor. Good luck. Nancy

Thanks for your input. I knew that the nail problem was a reflection of some health issues…just didn't know what to do about it. The DC responses have been helpful and I appreciate your contribution.

You might want your Endo to check you for a Thyroid condition. It can also cause brittle nails and hair loss. I was diagnosed type 2 diabetic first and the meds didn't change my nail condition. It wasn't until I was diagnosed with Hasimoto's Disease, a thyroid disease, that my nails cleared up. The med for my thyroid did the trick. In any case talk to your Endo and see what he advises.

I've been on thyroid meds for hypothyroid for over 20 years now…dosage last adjusted about 1 year ago. Endo regularly checks thyroid levels; ordered a thyroid scan and bone density test recently and blood work discovered I was deficient in Vitamin D so I'm taking 3000iu/day of that too. But maybe there's more going on with the thyroid, so I'll bring up the nail problem with them as well. Thanks for the input!

Biotin works well for diabetics only when paired with Chromium:

Biotin supplements have been studied as a treatment for a number of conditions. In people with type 2 diabetes, early research suggests that a combination of biotin and chromium might improve blood sugar. On its own, biotin might decrease insulin resistance and nerve symptoms related to type 2 diabetes. More research needs to be done. Some preliminary evidence suggests that biotin might help strengthen brittle nails. Other uses of biotin — for conditions like cradle cap, hepatitis, hair loss, and depression — are unsupported or untested.

However, most people don't need biotin supplements. We get biotin in foods naturally. Our bodies also recycle the biotin we've already used. Genuine biotin deficiency is quite rare.

Hello MAYS how are you?! Thanks for this info-much appreciated! Will an Endo run vitamin/mineral deficiency tests or do we see someone else for that? Anybody know?

MAYS 2011-08-03 13:28:33 -0500 Report

I am doing fine, how about yourself?

Your Endo should run a vitamin/mineral deficiency test for you, also ask to have a bone density test done.


Type1Lou 2011-08-03 12:28:23 -0500 Report

Thank you for your input…I had read about the chromium combination too. It was suggested that I try biotin supplements to resolve my fingernail splitting which I suspect may be caused, in part, by my diet, my diabetes and thyroid problems and maybe immersing my hands in water too much. At this stage, I'm willing to try it since the vertical nail splits are driving me nuts. The literature suggests that I notify my doctor of the addition of this supplement which I will do when I send in my BG readings this week. They did discover a vitamin D deficiency in March and had ordered a thyroid and bone scan last winter. Lord knows, I don't want to take any more meds but if the Biotin will help, it doesn't cost much to try it and find out.

Here is some info I found on Wikipedia about Biotin that I thought would be of interest to us diabetics. It was in the paragraph headed "Uses" WOW!

"Diabetics may benefit from biotin supplementation. In both insulin-dependent and non-insulin-dependent diabetics, supplementation with biotin can improve blood sugar control and help lower fasting blood glucose levels, in some studies the reduction in fasting glucose exceeded 50 percent. Biotin can also play a role in preventing the neuropathy often associated with diabetes, reducing both the numbness and tingling associated with poor glucose control.[17][18]
[edit] Hair & nail problems

The signs and symptoms of biotin deficiency include hair loss which progresses in severity to include loss of eyelashes and eyebrows in severely deficient subjects, as well as nails that break, chip, or flake easily. Biotin supplements are available in most pharmacies. The recommended dose is about 5000mcg to 7500mcg per day. Thicker and stronger hair and healthier nails may be seen within several months, depending on rate of growth.[citation needed]…"

Here is the link to the entire article:

I use Biotin mainly for my nails. It works great. I love how they look. I just wish i could stop the the nail biting. lol

Thanks for the input! I bought some yesterday and have begun to take it. I know it'll take some time to see the results but I'm hopeful with all the good feedback I've gotten. Thanks again!

Morning - Your nails show your conditions. When I am in control, my nails do well, but when I'm not for an extended period of time, it shows. I do get manicures and that helps keep them healthy. Yes, the thyroid out of control can also cause them issues. But I agree with rayfamily below - add some extra to help your nails (and hair) stay healthy. Oh - and treat yourself with a manicure. A good technician can also give you some tips and maybe some topical products to help them heal. Me all girl on my nails don't you know! ;)

Thank you for your input. I appreciate your taking the time to tell me what works for you and will try, both the biotin and manicure route.

I remember my Mom having the same problem when she was in the nursing home…but she was nearly 40 years older than me! I appreciate your telling me what worked for you. This is one of those annoying problems that many of us live with but we deal with so many more critical areas day to day, I almost felt petty starting a discussion about it. Thanks for the input!

Hi! New to the group- so I hope I'm not over stepping by posting!
I take 5,000 mcg's of Biotin everyday (well almost everyday). You can get a bottle w/ 150 caplets in them from Wal-Mart from under $4! Biotin is a skin/hair/nail supplement & since I've started taking them- my nails stopped splitting & I actually have to cut them every week or so because they're too long & too strong! I've turned many of my friends onto it too! They really work- try them!
Good Luck! :) Natalie

my nail's are always splitting> I am going to try Biotin. Is 5000 mcg a good dosage
I look today and they in 250, 1000, 2500..didn't see one for 5000

Type1Lou 2011-08-03 07:58:28 -0500 Report

I bought the 5000 mcg bottle at WalMart yesterday for $7. It has 120 capsules and says to take one 5000 mcg capsule per day. That averages to less than 6 cents per day. I'll have to do some research to see if it's better to take multiple smaller dosage tablets of Biotin over the course of a day rather than taking one big one all at once…calcium is like that…I take two 500 mg tablets of calcium citrate each day, one at lunch, one at dinner, for a total of 1000 mg. It's absorbed better that way.

rayfamily 2011-08-03 08:26:34 -0500 Report

Let us know what your research finds. I never thought of that. My bottle does say to take one, 1,000 mcg up to 5 times a day. I'll be interested to know if I should break up the doses. It's just easier for me to remember in the morning, when I take vitamins, long acting insulin, etc! I will say, I can definitely tell when I've been taking them. I honestly have to cut my nails- where I've never in my life had to trim them! I've told a few friends about it & they swear they saw a change within a week!

rayfamily 2011-08-02 19:03:16 -0500 Report

I buy it in 1,000 mcg caplets. The instructions on the back say you can take one pill up to 5 times a day. I just take 3 or 4 or 5 every morning with my other vitamins. (Deoends on my mood!) Just read the label- I purchase the least expensive one (which also has the lowest mcg's, so I have to take more) If you're willing to spend a couple extra bucks, you can get one pill that will have 2 or 3,000 mcg's. I get it right over the counter at Wal-Mart in the vitamin isle! Good Luck! :)

Thank you for the tip! I will get some biotin tomorrow and hopefully, will be on the path to better nails!
