Vitamin C, Zinc, Vitamin D, Iron → protect you from frequent illness.

2. Energy Production

B-vitamins, Iron, Magnesium → help convert food into energy.

3. Brain & Mood

Omega-3, B12, Vitamin D → support memory, mood, and focus.

4. Bone Strength

Calcium, Vitamin D, Magnesium → keep bones strong.

5. Muscle & Nerve Function

Potassium, Magnesium, Sodium → maintain muscle movement and nerve signals.

6. Skin, Hair & Nail Health

Biotin, Zinc, Iron → reduce hair fall and support healthy skin.

Even mild deficiency can affect daily life and many people don’t notice it until symptoms worsen.
