Essential for the proper functioning of the nervous system and cellular vitality, vitamin B12 directly affects the condition of your nails. A deficiency can lead to fatigue, concentration problems , and yes, those famous streaks. Vegan diets or certain digestive disorders
may be implicated . Consider fortified foods or appropriate supplements, but always consult a healthcare professional.
Thyroid in slow motion: revealing clues
The thyroid gland influences nail growth and regulates our energy and body temperature. If it acts slowly, nails become dry, brittle, and ridged . Unexplained weight gain, feeling cold, or low energy— all of these signs, when combined, can raise suspicion.
A simple hormone test (TSH, T3, T4) can provide clear answers.
Stress: an often underestimated impact
Chronic stress acts as a silent exhaustor : it depletes nutrient reserves and impairs their absorption . The result? Nails grow more slowly, become ridged, and more brittle. This phenomenon is exacerbated if we tend to bite our nails or neglect our lifestyle .
Take the time to breathe, to breathe, to move… your nails will thank you.
Capricious digestion: altered absorption
Even with a balanced diet, if your digestive system is compromised, vitamin absorption can be compromised. Bloating, irregular bowel movements, digestive discomfort—these are many telltale signs. What if ridges on your nails are a secondary consequence of this internal imbalance ?
Focus on fiber, simple foods, and listen to your body’s signals.
A bad habit: biting your nails
It may seem trivial, but nail biting damages the nail matrix , which can lead to persistent ridges or even infections. This action, often linked to stress or boredom , weakens the nail’s very structure.
Bitter-tasting nail polish or stress management exercises can help break this habit permanently.
A kind attention to give to oneself
Vertical ridges on your nails are usually benign, but they’re never there without a reason . Whether it’s stress, a deficiency, or a digestive imbalance , they’re an invitation to listen more to your body . So, the next time you notice them, ask yourself this simple question: What do I really need today?
