Of course you know that calcium is important for strong nails, but there is another important nutrient that will give you super nails. Its call biotin. You can find it in eggs, wheat germ, oat bran, peanuts,.
You may be old enough to remember Knox Gelatin for nails. Gelatin, including Jello, contains a powder made from horse hooves. There are people who swear by it, and those who say it’s an old wives tale. My grandmother swore by it and she always had long nails. I’ve never really tried it and I have strong nails. I can’t tell you one way or the other.
You may have also heard that your nails can signal health problems. If the moon portion at the base of the nail is white and sunken, that signals an iron deficiency. If you have lines going across the nail, it could signal inflammation. Lines going up and down from the base to the tip are just age. A red color under the nails signals a possible biotin deficiency.
