I take a vitamin for hair and nails..Mine keep flaking..plus they have dents and ridges..

hmm i have ridges to on my nails

No not flattened but mine has gotten ridges and are more brittle. I can't wear nail polish because it tares up my nails.

I take Vitamin D3 daily. My nails grow fine. My meds don't exactly have that effect. I'm not on any heavy duty fibro drugs.

I have learned that it is soooo important to get your vitamin D checked because when you are supposed to spend 10mins in the sunlight everyday to get the correct amount of vitamin D your body needs .. But most people with fibromyalgia well me for example I don't go in the sun so my vitamin D was critically low .. So I had to go on the 50000 unit for of vitamin D .. The medications we take block our bodies ability to absorb certain vitamins and minerals.. That is why it is important to take the medications as directed. I use coconut oil its amazing for hair and nail growth 😊
