Here are some of the vitamins I take. And my nails are looking fabulous!
GNC Ultra Women's Active Multi vitamin
Vitafusion Gummy Vitamins - Vitamin C 250 (Target has this brand or you could buy them on-line)
Vitafusion Gummy Vitamins - Calcium 500 with vitamin D 1,000
I just wanted to add that after taking the GNC Womens vitamins for a month I got really sick. So sick that my doctor's thought I had lymphoma and I had to had a lymph node removed for a biopsy. I had to completely stop all of them and start from scratch. The GNC vitamins were the newest vitamins I started to take, but I really suspect it was the Vitafusion vitamins, but I'm not 100% sure. I was taking them for months and then all the sudden they changed the label, but I called and they told me there weren't any changes in the product, so I really trusted this company. As soon as I figured out it was the vitamins, I stopped them and started to get better.
Please be careful with any vitamin even if it says it's gluten free. I had to learn the hard way.
I recently started Kirkman Labs multi vitamin just 8 days ago. Even though I eat healthy I'm still low on some of my vitamins. So far I haven't had any reactions to them and I'm super sensitive. Plus I do keep a food diary.
