Yes, a magnesium deficiency can be a contributing cause of vertical nail ridges. However, vertical ridges are also a common and often harmless sign of aging.
“When someone is deficient in magnesium, it can show up as weak, flaky nails,” says Dr. Nussbaum. Getting adequate magnesium may also help prevent vertical ridges from forming, so nails grow strong, smooth, and even.
A magnesium deficiency can result in weak, flaky nails that are prone to breakage.
Zinc deficiency can cause Beau's lines and white spots on your nails. Iron deficiency can cause vertical nail ridges and koilonychia (spoon nails). Spoon nails have a depression in the middle, like the center of your nail was scooped out. You may be able to hold a drop of water on your nail.
Magnesium is a mineral that involved in over 300 reactions in your body, including protein synthesis, which is a crucial process required for nail growth. Magnesium deficiency could potentially give rise to vertical ridges in your nails, making them look damaged, and less attractive.
Your body needs magnesium to function normally. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms. A blood test or urine test can be used to diagnose magnesium deficiency. Magnesium deficiency is usually treated with supplements.
Aging is one of the most common causes of tiny vertical nail ridges (onychorrhexis), which extend from the bottom of the nail to the tip. Most people have some faint vertical nail ridges when they're younger. The ridges may become more pronounced over time as the nails naturally get thinner and more brittle.
Vertical Ridges: These are usually harmless and often become more prominent with age. Horizontal Ridges (Beau's Lines): These can be a sign of more serious issues, such as illness, malnutrition, or trauma to the nail.
Medium to dark vertical lines on your nails could indicate a Vitamin D and B12 deficiency. Short white lines or spots might point to zinc deficiency. Brittle nails that easily break could mean you're low in calcium and biotin.
Onychorrhexis mainly causes vertical ridges and splitting of the nails. Nail pitting is more common with other issues, such as psoriasis, fungal infections, or certain autoimmune diseases.
If your fingernails change color or you develop horizontal nail ridges, consult your health care provider. These changes could indicate an underlying health condition.
Ask your healthcare professional about biotin.
Some research suggests that the nutritional supplement biotin might help strengthen weak or brittle nails.
Brittle or spoon-shaped nails
Brittle nails chip and crack easily. Spending a lot of time with your hands in water or using some nail polishes can lead to brittle nails, but brittle nails can also be a sign of iron deficiency. Another sign of iron deficiency is 'spoon-shaped nails'.
When taken in doses greater than 350 mg daily, magnesium is possibly unsafe. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
How to Get Rid of Fingernail Ridges
Not everyone has a visible lunula. Missing lunulae can be due to genetics, age, nail thickness, or cuticle thickness. Sometimes, missing lunulae can be related to health issues, like poor circulation or nutritional deficiencies.
Vitamin B12 deficiency can significantly affect nail health, leading to brittleness and vertical ridges. It's essential to keep your B12 levels healthy by consuming foods rich in this vitamin, such as meat, dairy, and eggs.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
When your body lacks calcium, your nails become thinner, weaker, and brittle. You may notice that they break easily and just don't look as healthy as they used to. Although nails and bones are made up of different substances, they're similar enough that poor nail health may be an early marker of bone density problems.
Horizontal ridges can be caused by trauma to the nail and may be deep or discolored. They can also indicate malnutrition, psoriasis or a thyroid problem.
Heart failure nails often show nail clubbing, where fingertips enlarge and nails curve downward like an upside-down spoon due to poor oxygen flow, feeling soft and warm, but can also present as blueish tints (cyanosis) or splinter hemorrhages (tiny red lines under nails) from heart infections (endocarditis). Other signs can include Terry's nails (mostly white with a pink tip) or Mees lines (horizontal white bands). These changes signal serious underlying issues, requiring prompt medical evaluation.
Beau's lines are horizontal, going across the nailline, and should not be confused with vertical ridges going from the bottom (cuticle) of the nail out to the fingertip. These vertical lines are usually a natural consequence of aging and are harmless.
Longitudinal ridges
Often referred to as "nail wrinkles", they usually appear with age or, for some, around the time of menopause. They suggest the body is producing less keratin and that hormone levels may be unbalanced. Longitudinal ridges can also point to vitamin or mineral deficiencies.
Liver failure nails often appear as Terry's Nails, characterized by an opaque white or "ground glass" look across most of the nail, with only a thin, brownish or pinkish band at the very tip and the half-moon (lunula) often disappearing, though other changes like ridges or yellowness (jaundice) can also occur, indicating systemic issues.
