Vitamin A is essential for the body to process proteins. When there is a deficiency of this vitamin it may cause dry, brittle nails and hangnails. Beta carotene and vitamin A work together in stimulating new cell growth and protecting your cell membranes. Foods that are rich in beta carotene and vitamin A may include spinach, carrots, watermelon and broccoli, to name a few. A diet with enough Vitamin A will assist in bringing weak, cracked nails back to life. MayoClinic.com states that adult women should consume 700 micrograms, or mcg, per day and 900 mcg for adult men.
Vitamin B2 is a member of the B complex group and is also known as riboflavin. This vitamin is essential for overall health and growth and plays a role in the digestion process. According to Vitamins & Supplements, Riboflavin is vital for development and repair of body tissues such as nails, skin and hair. Our bodies do not store this vitamin; therefore it must be replenished daily. A vitamin B2 deficiency may lead to split and dry brittle nails. Whole grains, green leafy vegetables, liver, milk and cheese are good sources of riboflavin. The recommended daily dosage of riboflavin varies depending on gender and age, states The Vitamin & Nutrition Center.
Your body needs vitamin D to enhance calcium absorption. Calcium is essential for strong bones, teeth and nails. This vitamin is found in very few foods and may be added to others. Some foods that are rich in vitamin D are cheese, egg yolk and certain fish, such as salmon, mackerel and tuna. Dry, brittle nails can result from a vitamin D deficiency. The Office of Dietary Supplements states that excessive amounts of vitamin D in your body can lead to vitamin D toxicity, resulting in nausea, poor appetite and weakness. Your age and gender determines the recommended daily allowance of vitamin D. Always consult with your physician prior to starting a supplement regimen.
