VCZ-D3 TAB
VITAMIN C + VITAMIN D3 + ZINC TAB
VCZ-D3 TAB is a tablet combining vitamin C, vitamin D3 and zinc. It is used as a supplement for immune support during and after respiratory infections, in convalescence, and where dietary intake of these nutrients is inadequate.
01
Benefits
- Vitamin C is required for collagen formation, wound healing and normal immune function, and is not stored by the body.
- Vitamin D deficiency is widespread in India and is associated with impaired immune function as well as bone disease.
- Zinc supports immune function, wound healing and taste perception, all impaired in deficiency.
- The three nutrients act on complementary aspects of immune defence and tissue repair.
- Once-daily dosing is simple to sustain over the weeks a nutritional gap takes to close.
02

- Loose stools or diarrhoea
- Abdominal cramping
Less common
- Heartburn
- Headache
- Constipation
- Loss of appetite
Stop and get medical help if any of these occur
- Loin pain or blood in the urine, as high-dose vitamin C can promote oxalate kidney stones
- Marked thirst, frequent urination, confusion or unusual drowsiness, which may indicate high calcium from excess vitamin D
- Persistent vomiting or severe abdominal pain
- Swelling of the face, lips or tongue, or difficulty breathing
- Widespread rash or hives
03
Precautions
- Do not exceed the stated dose or take alongside another vitamin D or multivitamin preparation — vitamin D is fat-soluble and accumulates to toxic levels.
- High-dose vitamin C increases the risk of oxalate kidney stones; use with caution in a history of stones and in renal impairment.
- Prolonged high-dose zinc causes copper deficiency — do not continue high doses indefinitely.
- Contraindicated in hypercalcaemia, in glucose-6-phosphate dehydrogenase deficiency, and in haemochromatosis.
- Zinc impairs absorption of tetracycline and fluoroquinolone antibiotics — separate doses by at least two hours.
- Take with or after food to reduce nausea.
- A supplement, not a treatment for infection, and not a substitute for assessment of a persistent illness.
