Clinical monograph

How it works

It supplies vitamin A for vision and immune and epithelial function, vitamin C for collagen formation and antioxidant defence, and vitamin D to support calcium absorption and bone mineralisation.

Prescribing in practice

  • Vitamins A and D are fat-soluble and accumulate, so carers must avoid giving additional vitamin-A- or vitamin-D-containing products concurrently to prevent cumulative excess.
  • Dosing is age-banded for young children; confirm the appropriate preparation and amount against a children's formulary and national supplementation guidance.
  • Check whether the child already receives vitamin D or a multivitamin from another source before adding this product.

Monitoring

Routine biochemical monitoring is not required for standard supplementation in an otherwise well child taking the recommended amount.

Counselling the patient

  • Use the dropper or measure provided and do not exceed the stated amount.
  • Do not give other vitamin A or vitamin D supplements at the same time.
  • Continue daily supplementation through the recommended early years for healthy growth.

Evidence & guidelines

UK healthy-start guidance recommends daily vitamin A, C and D supplementation for young children to prevent deficiency, particularly where dietary intake may be inadequate.
