Talk to experienced dermatologist online and get your health questions answered in just 5 minutes.
From the image, the light brown longitudinal line on the toenail appears consistent with a condition called longitudinal melanonychia, which means a pigmented line running along the nail. In many cases this can occur due to minor nail matrix activation, previous trauma, nutritional deficiencies, or benign pigment deposition.
Since your blood test shows Vitamin D deficiency (7.4) along with Iron and Vitamin B12 deficiency, nutritional deficiency can sometimes contribute to nail changes, ridging, or pigmentation changes.
Next Steps
I would recommend a proper evaluation to confirm the diagnosis and rule out other causes.
You may also take an online consultation with me and share clearer close-up images of the nail, so I can assess the pattern of pigmentation and guide you regarding whether it is a benign nail change or needs further investigation.
Early evaluation will help avoid unnecessary worry and ensure appropriate management.
