fingernail problems

Customer Question

My fingernails on one hand are cupping. Wonder if it is a vitamin or mineral deficiency.

I found this information for you hope this helps.

Abnormalities or changes in your nails oftentimes are based on nutritional deficiencies or unfortunately underlying conditions or disorders. Downward-curved nail ends may simply be the result of a vitamin B-12 decificency or may be giving off underlying warning signs of impending heart, liver or respiratory problems. It's advisable to seek medical attention if you suspect any symptoms.
Also, B-12 or iron(anemia)deficiencies can cause "spoon" nails (i.e., concave-shaped nails) or vertical ridges. White spots come from a zinc deficiency. Brittle, dry nails lack vitamin A and calcium. Very rounded, darkened, upward or downward curled nails, again, lack B-12. Insufficient protein, folic acid and coral calcium-magnesium-D3 result in hangnails and stunted nail growth. Splitting, chipping, peeling, cracking or easily breakable nails lack sufficient hydrochloric acid (HCI), minerals and protein.
Try taking a multivitamin daily along with added B-12 and vitamin A (the body can't utilize protein without it) in the recommended dosage amount given on the label of the bottle. Flora by Floradix is probably good, too, in the best vitamin-herbal blend for effective iron absorption (but don't take it unless anemia is diagnosed by your physician). Lastly, borage and silica help with maintaining healthy skin, hair, bones and strong nails.
Maintain a healthy diet: fresh fruits and (raw to lightly-steamed) vegetables, including melons, blueberries, kiwi, grapes, raisins, bananas, pineapples, and broccoli, brussel sprouts, cauliflower, salad, spinach; protein in the form of eggs (the yolks --- if your cholesterol levels are normal), fish (salmon, tuna [albacore], mackerel, sardines), chicken, turkey, oatmeal, whole grain bread and cereals, peanut butter, Brewer's Yeast, wheat germ, soybeans, legumes (peas, beans), nuts and seeds. As always, again, it never hurts to consult your physician first.
