Nail Changes Indicate Health Issues: Changes in the shape, color, and texture of nails can signal underlying health problems, including nutritional deficiencies and digestive issues.

Vertical Ridges Linked to Nutritional Deficiencies: Larger, deeper vertical ridges on nails may indicate a deficiency in Vitamin B12 and heme-iron, affecting oxygen flow to the nail matrix.

Brittle Nails Associated with Absorption Issues: Brittle or splitting nails are commonly linked to a lack of folate, iron, biotin, or calcium, often due to poor nutrient absorption rather than insufficient intake.

Clubbing of Nails Signals Oxygen Deficiency: Enlarged, rounded nails, known as clubbed nails, can indicate insufficient oxygen in the blood, potentially linked to serious conditions like liver damage or lung disease.

White Spots on Nails Indicate Zinc Deficiency: The appearance of white spots on nails is often a sign of zinc deficiency, which can result from high sugar intake that depletes zinc levels.

Blue or Purple Nails Reflect Circulation Problems: A blue or purple hue under the nails suggests inadequate oxygenation due to poor blood circulation, which can be exacerbated by cold exposure or chronic stress.

Horizontal Ridges Suggest Vitamin Deficiency: The presence of horizontal ridges on nails may indicate a deficiency in B-vitamins, particularly Biotin, which is essential for nail health and growth.
