Congratulations! You have stopped biting your nails and need them to grow faster. This is completely understandable; While stopping nail biting is the most important thing in the long term, in the short term, you want your nails to look as beautiful as possible.
Fortunately, you are not alone, and since necessity is the mother of the invention, many possible solutions have been discovered to accelerate nail growth, but the most important thing is to strengthen the nail to avoid excessive wear. Some of the more ridiculous solutions really help significantly. Many vitamins and some minerals are also vital in creating the keratin that your nails are made of. Also, if you're not the type of person who likes taking vitamins, there are a few nail care steps you can take to avoid damaging your nails that will send you right back to where you started.
Vitamin D, a fat-soluble vitamin (fat-soluble means it stays in your body for a few days), is a vitamin found in sunlight and certain fats. One of its many functions is to help the small intestine break down calcium and increase the effectiveness of calcium. While vitamin D itself does not help nails, calcium is one of the best vitamins to help your nails grow faster after a lifetime of nail chewing.
Calcium, which, as most people know, is found in whole milk, which is why it really works to soak your hands in milk. While it may sound like an old wives tale, calcium is absorbed quite effectively through the skin, and because keratin is almost two-thirds of water, it can absorb water from milk to increase its growth and strength.
