Lucozade Alert vs Energy vs Sport: caffeine compared
The short answer
The product family matters: Alert contains 32 mg per 100 ml, Energy approximately 12 mg per 100 ml, and the reviewed FAQ says Sport drinks contain no caffeine.
| Range | Per 100 ml | At 500 ml | Basis |
|---|---|---|---|
| Alert | 32 mg | 160 mg | Both amounts manufacturer-listed |
| Energy | Approximately 12 mg | Approximately 60 mg | 500 ml amount calculated |
| Sport drinks | No caffeine | No caffeine | Manufacturer range statement |
500 ml is a comparison volume, not a claim about every package. Energy flavours can vary. Check the precise current product label.
Inspect the documented servings
These values come from the linked catalogue records. A source-backed record is not a measurement of your drink or a guarantee of a current recipe.

Bars use the selected measure; numbers remain visible in both units. No bar is drawn for an undocumented concentration. Per 100 ml = serving caffeine × 100 ÷ documented volume.
Read the range name before the bottle size
A search for “Lucozade caffeine” can mix three different products. Identify Alert, Energy or Sport on your package before entering anything into a calculator. The shared brand name is not a recipe, and colour or flavour is not enough to identify the caffeine dose.
Convert concentration into your portion
Multiply mg per 100 ml by the amount you actually drink, then divide by 100. At Energy’s approximate 12 mg per 100 ml, a 250 ml portion would be approximately 30 mg. This is arithmetic from the range statement, not a separate tested product value.
Keep the comparison narrow
The table compares caffeine only. It does not establish that the drinks are interchangeable for sport, hydration or nutrition. For a different range or a reformulated bottle, use its own current label rather than extending this table.
