Vicks
Posted by Julie (Daly City, California) on 04/19/2014
I read somewhere about a year ago that V**ks V***rub works to kill toenail fungus. Well one day I tried it. Then I forgot about it until one day when I went to cut my toe nails and I thought, wow, is it my imagination or did that one time of rubbing the v**ks into my toe nail really work because my nails looked slightly better. So I rubbed a little on again and again forgot about it for a bit and then remembered and took a closer look. My nails looked a little better. I rubbed it on them again and the next time I checked I swear my little toe nails were looking flatter and started to look less like the fat lump of a toenail they had become. The other nails started to look like they were flattening out too...meaning they weren't growing away from the nail bed so much because of the noticeable disappearance of that substance that grows under the nail associated with the fungus. I am not diligent about applying it probably everyday like I should but I was impressed with the results after only 3 applications done at least a month apart. I am going to try and be more consistent with applying it, hopefully everyday, and see what happens but I honestly saw a difference with just those three times and had seen no difference with other over the counter type applications. I will post my results, if any, in the future but as God as my witness, I swear, there is a difference. It doesn't seem to hurt the nail or the skin and it's worth a shot and hopefully I will be posting positive results sometime soon!

My fingernails were soft and frequently broke. I starting taking 1000 mcg biotin twice a day, and within 2 months, they became rock solid. I stopped taking biotin for a while, and my nails returned to being soft. When I started taking the pills again, my nails toughened up. Karen

Be mindful of Silica dosages, side effects, and warnings!
Silica is also used to breakdown/dissolve hard tissues like fibriods, cysts, tumors, etc, which may also may unlease thier contents, including toxins, infectious agents, cancerous tissue, etc. I began taking silica (oral, homeopathic) in attemps to relieve painful fibroids and troublesome scar tissue under my foot; but the silica first dissolved an age-old cyst imbedded under my scalp (which I didn't know was there; leftovers of a decades-old boil that was removed completely, intact). When the silica dissolved the cyst it spilled the (previously contained) infection into surrounding tissues (infecting nearly my entire scalp). I've been fighing/treating this scalp infection for well over a year now, and it's been a painful, difficult, and troublesome battle every day, including hair loss!

You can't unfortunately get it in Australia.. Try ebay from overseas.

I am thinking to try this, because I too have hypothyroidism and really, REALLY want my fingernails to grow out nice and long. I do take vitamins every day!

I've noticed that when I take MSM, my fingernails grow like crazy! The split cuticle issue that I have (especially in the winter) disappears in about 48 hours. I'd say it's the best remedy for the nails

Just try the amount suggested on the bottle each day. Increase if needed to get results.

Hi, do u mix the 2? If so how much of each. Thanks
ACV and Coconut Oil
Posted by Karen (Canada) on 03/06/2015
I am willing to try this. I'm assuming you take it by mouth. I put a teaspoon of coconut oil and 2 tsp. cider vinegar in a glass and I just drink it. I hope I see good results.
Biotin

I've been taking a 250mg supplement of Biotin once a day for about 3 weeks before I noticed the changes in my nails! They are harder, they don't break or chip as easily. I went on vacation for 2 weeks and forgot my Biotin. Lo and behold, near the end of the 2 week vacation I had broken one nail and chipped another!
I am back on the Biotin. I've also added the de-colorized Iodine to my repertoire and will report back after a week or two. Thanks for all the great advice Earth Clinic!!!
Biotin

I feed my horses biotin for their hooves. It takes almost a year to see real results. The hoof that forms with biotin is stronger. It can't improve existing hoof. Hooves grow out like nails do from a nail bed. I would assume that it is the same with nails but it doesn't take so long to grow a whole new nail. I think after 3-4 months on biotin, the old nail would be gone and biotin fortified nail would have grown in. I don't think being off biotin for a week or two would make a difference.

Fish oil was recommended to me as a supplement from a personal trainer....happened to notice after a couple of weeks that my nails were actually growing and not breaking nearly as much!!! Didn't realize it had a benefit to nails also! Will definitely keep taking for my nails!

Silicon is not present in large amounts, yet found in every type of tissues in the body. Silicon is used to keep bones, cartilage, tendons and artery wall healthy. It is required by the nails, hair and skin, silicon levels drop as we age. So if cartilage is not in any joint after surgery, silicon will replace it. If you want nice hair, and nails, silicon is also called silica. I take it and I have good hair and nails that look good and they are hard. If you do not have any idea where to get some, look to the internet. It has information on healthy products.

For those who use Silica for nail strenthening, how long before you notice an improvement...
Thank you

Do you swallow it or put it directly on your nails? How much of it and how often do you use it?

Hey guys, was checking out remedies for weak, brittle nails and came up with silica as one answer. I don't know if it works well or not, but be aware that there are some scary side effects. Look into it thoroughly before using!!!

I've had skin tags in the past and my doctor told me not to worry as they soon outgrow their blood supply and eventually just drop off.
And they did! :)

I see a Thyroid Specialist for hypothyroidism. I was complaining about my weak, brittle nails when he suggested that although my thyroid was functioning properly (too much or too little thyroid function can cause weak nails), that I may be deficient in folic acid. I'm not as faithful about taking my vitamins and supplements as I should be, but I do notice that when I take a folic acid supplement that my nails become stronger and break less often. You can buy folic acid as an individual supplement, but you can buy multivitamins with folic acid in them.

MSM
Posted by Carmen (Brandon, Florida) on 12/25/2008
I am experiencing early menopause due to a hysterectomy and along with the many other changes I am encountering I find my nails are weak. During a search I found MSM, what exactly is this? And is it safe to take with harmone replacement?
MSM
Posted by Kim (Grants Pass, OR) on 04/03/2009
Hi Carmen, I just read your post. I too am having menopause issues from a hysterectomy at the early age of 26, which in turn turned into a hypothyroid issue, which left untreated, turned out to be pretty severe. Make sure you keep yourself educated, doctors that you pay to know health issues, typically DON'T know. Feel free to email me anytime. And my fingernails, bend easier than paper!!!

Just be careful with molasses, especially if you are diabetic.. Not a good remedy for diabetics or those who don't know they are diabetic. A whole cup seems excessive.
