Do not give this Betonin AST syrup to your 3.5-year-old.

The label says it is recommended only for children above 6 years, and it contains 9% v/v alcohol. It is not a routine nutritional supplement for preschool children without a pediatrician’s advice.

For your 8-year-old, the bottle’s stated dose is:

However, I would still suggest using it only if a pediatrician has recommended it for a specific reason such as poor appetite or a documented nutritional concern. Poor appetite can also result from constipation, iron deficiency, recurrent infections, picky-eating patterns, or growth concerns, which a tonic may not address.

The manufacturer confirms the formulation contains 9% alcohol and zinc, B vitamins, and lysine in each 15 mL dose on its Abbott product listing. If either child is taking any regular medicines or has liver disease, vomiting, unusual sleepiness, or poor growth, please check with their pediatrician before using it.
