Fingernails reflect the body's internal condition.
Just as plants can reflect soil conditions, fingernails can reveal the body's nutritional status. Different nail changes are often associated with deficiencies in specific vitamins or minerals.

Common nail abnormalities and possible nutritional deficiencies
- Vertical color change in the middle : May indicate a deficiency in protein, vitamin D , or B12 . If protein intake is insufficient, B12 levels may also be low, as B12 primarily comes from animal protein.
- Horizontal stripes : May indicate a deficiency in vitamin B3 , calcium, or zinc.
- White spots : This usually indicates zinc deficiency, commonly seen in people with high-carbohydrate diets. Nail growth takes six months, which can be used to estimate when zinc deficiency might occur.
- Brittle or brittle nails may indicate a deficiency in vitamin B6 or magnesium, or they may be related to insufficient iron or stomach acid. Insufficient stomach acid can affect mineral absorption.
- Completely white nails : This may be due to severe protein deficiency, impaired kidney or liver function, or possibly related to antibiotic use.
- Soft nails : May indicate calcium deficiency. Vitamin D helps with calcium absorption and can increase nail hardness.
- Square or bulging nails : may be associated with heart, liver, or lung problems, often related to lack of oxygen.
- Spoon-shaped nails (curved upwards) : Commonly seen in people with iron deficiency.
- Bluish nails may indicate insufficient oxygen.
- Yellowish nails : This may be due to jaundice, which is related to bile duct obstruction or gallbladder problems. Supplementing with bile salts may be considered.
- Discoloration at the base of the nail or loss of the lunula : This could indicate cirrhosis of the liver, heart problems, or diabetes.
- Nails that are deformed, too thick, or have horizontal ridges in the center may indicate a deficiency in biotin (vitamin B complex).
- Vertical red lines : These indicate ruptured capillaries, possibly due to vitamin C deficiency , and may also be accompanied by bleeding gums or spider veins.
- Vertical texture : may be associated with insufficient protein, high-carbohydrate diet, B12 or iron deficiency, especially in those with insufficient animal protein intake.
