Margi59, Burt’s Bees makes a product called Lemon Butter Cuticle Crème, and it receives good reviews. Don’t think that you have to buy a commercial nail care product. You can use something like jojoba oil, almond oil, rosehip oil etc for your nails and cuticles.
I have very fragile nails that break easily. My nails do not tolerate some mainstream brands with more harsh chemicals. My nails are much better if I use nail polishes, nail polish remover etc from brands that formulate products with less harsh chemicals. (So far, there is no such thing as nail polish without man-made/synthetic chemicals.)
Mainstream nail polish removers can really strip the moisture from my nails, but they are much better if I use a remover such as Fresh Therapies Nail Polish Remover or a soy-based remover from another brand. I also highly recommend that you use a crystal nail file which is not so harsh on fragile nails.
There are an increasing lot of brands making nail polishes that are kinder to nails:

Also, look out for some great indie nail polish brands that are not so well-known.
You may also wish to take a supplement for hair, nails and skin from brands such as Blackmores. Many people claim that biotin is beneficial for healthier nails.
