To grow, healthy nails require good circulation, careful attention and good nutrition. Thus, improving blood flow, following a good nail regimen, and taking vitamin supplements are ways to help your nails stay healthy and grow well.
Nails become brittle due to a decrease in circulation caused by the aging process, so 20 to 30 minutes of cardiovascular exercise a day, which increases the blood flow to the hands and feet, is good for them. A daily nail massage also increases the blood flow. A mixture of lemon juice, olive oil and sugar can be rubbed on the nails for 5 to 10 minutes a day.
Establish a healthy nail regimen. Nails should be buffed by rubbing up and down rather than side to side. The cuticles are the nail's barrier against infection and fungus, so they should never be trimmed or pushed down aggressively. Brittle and flaky nails can be strengthened by taking a daily dose of 300 micrograms of biotin, a B vitamin supplement, with a meal. Adding fatty acids to the diet also improves nail health. Eat fatty fish such as salmon, or sprinkle ground flaxseeds on cereal. Flaxseed oil can be added to or used in place of salad dressings. Zinc is also important for nail health. Nuts, root vegetables and whole grains are good sources of zinc.
