Caffeine is a stimulant regulated as an ingredient in India. FSSAI caps caffeinated beverages at 320 mg per litre and requires the warning "not recommended for children, pregnant or lactating women" on energy drinks. It is the only ingredient in our data with its own statutory warning label.
Energy drinks state caffeine per 100 ml or per can — a 250 ml can at 30 mg/100 ml is 75 mg, about the same as instant coffee.
Colas carry roughly 10 mg per 100 ml; the FSSAI warning text appears on energy drinks, not colas.
"No added caffeine" on a cola still permits caffeine from kola nut or added flavouring below declaration thresholds.
Caffeine per 100 ml is a weighted input to the negative load for beverages, and caffeinated products surface a flag for profiles that set a caffeine preference.
