Vitamin B12 is important for nervous system function and cell vitality and directly influences the condition of your nails. A deficiency can lead to fatigue, concentration problems, and—yes, the famous streaks. A vegan diet or certain digestive disorders
may play a role. Consider consuming fortified foods or appropriate supplements, but always consult a doctor.
Thyroid in Slow Motion: Revealing Clues
The thyroid influences nail growth and regulates our energy and body temperature. If it reacts slowly, nails become dry, brittle, and cracked. Unexplained weight gain, feeling cold, or lack of energy—all of these signs combined can raise suspicion.
A simple hormone test (TSH, T3, T4) can provide clear answers.
Stress: An Often Underestimated Effect
Chronic stress acts like a silent exhauster: It depletes nutrient reserves and impairs their absorption. The result? Nails grow more slowly, become cracked, and brittle. This phenomenon is exacerbated if we tend to bite our nails or neglect our lifestyle.
Take time to breathe, breathe deeply, and exercise… your nails will thank you.
Irregular Digestion: Altered Absorption
Even with a balanced diet, vitamin absorption can be impaired if your digestive system is compromised. Bloating, irregular bowel movements, indigestion—these are many telltale signs. What if ridges in your nails are a result of this internal imbalance?
Focus on fiber, simple foods, and listen to your body’s signals.
A Bad Habit: Nail Biting
It may seem trivial, but nail biting damages the nail matrix, which can lead to permanent ridges or even infections. This activity, often associated with stress or boredom, weakens the nail structure.
Bitter-tasting nail polish or stress management exercises can help you break this habit permanently.
A loving gesture to yourself
Vertical ridges on your nails are usually harmless, but they’re never there without a reason. Whether they’re caused by stress, a nutritional deficiency, or a digestive disorder, they’re an invitation to listen more closely to your body. The next time you notice them, ask yourself this simple question: What do I really need today?
