Monster Ultra versus Original Monster
The clearest difference in these records is sugar and calories. Zero sugar does not mean zero caffeine, and a lower calorie figure is not a lower caffeine figure.
United Kingdom: white Ultra has 150mg caffeine, 0g sugar and 11 kcal per 500ml can. Original Green has 160mg caffeine, 55g sugar and 237 kcal per 500ml can.
United States: white Ultra has 150mg caffeine, 0g sugar and 10 kcal per 473ml can. Original Green has 160mg caffeine, 54g sugar and 230 kcal per 473ml can.
Match the serving before comparing
A UK 500ml can and a US 16 fl oz can are different volumes. An imported can may use the recipe and labelling of its original market. Use the country, product name and volume together, rather than choosing by can colour alone.
Our calculator starts with one whole can. Change the quantity to 0.5 for half a can, or add other drinks to include their caffeine too. For example, half of a 150mg white Ultra contributes 75mg. The total covers only what you enter.
For caffeine references and individual sensitivity, read our caffeine guide and its published health sources. This page compares product labels; it does not determine how much caffeine is suitable for you.
Common Monster Ultra questions
Does every Monster Ultra have the same caffeine?
No. Use the regional flavour cards above: the catalogue includes different amounts within the Ultra range. Similar names across countries do not guarantee matching recipes.
Is Monster Ultra caffeine-free because it is sugar-free?
No. Caffeine and sugar are separate ingredients. The white cans shown above have zero sugar and 150mg caffeine each.
Is white Monster Ultra completely calorie-free?
The records shown here list 11 kcal for the UK can and 10 kcal for the US can. We use the serving-specific nutrition figures, rather than assuming that zero sugar means zero calories.
What if the label on my can is different?
Match the flavour, volume and market first. Formulations can change. Use the packaging for the drink in your hand, and send us the label details so we can check the catalogue.
Who put this guide together?
TotalCaffeine was built by a web developer with a love of energy drinks. This guide uses the same regional records as the calculator, with manufacturer and retailer label sources linked beside the figures. It is an independent comparison, not a Monster-sponsored page or a laboratory test.
Each card shows its own source-check date. These checks cover the listed size, caffeine, sugar and calories, not taste or health benefits. Meet the founder and read our methods, or send corrections to [email protected].
