If your skin looks unusually pale or dull, it could signal low iron levels. Iron deficiency reduces red blood cells, lowering oxygen supply. Fatigue, weakness, and cold hands often accompany it.

Brittle nails (biotin deficiency)

Thin, weak, or spoon-shaped nails may indicate low biotin. Biotin supports keratin production, vital for nail and hair health. Persistent nail breakage could be your body asking for more nutrients.

​Frequent mouth ulcers (vitamin B deficiency)

Recurring sores inside the mouth can point to deficiencies in B vitamins, particularly B12. These nutrients help repair tissues. Low levels weaken immunity and make healing slower.

Hair loss (zinc deficiency)

Sudden hair thinning or shedding may be linked to zinc deficiency. Zinc supports tissue repair and growth. Without it, hair follicles weaken, leading to noticeable loss.

Bleeding gums (vitamin C deficiency)
