The Snickers Marathon Protein Bar is a dense, chewy, and surprisingly satisfying nutrition bar designed for active individuals. It delivers a robust 25 grams of protein per 100g, wrapped in a classic candy-bar flavor profile of nougat, caramel, and peanuts. Its standout feature is the substantial fiber content, which helps balance its significant carbohydrate load.

↓ Full nutritionPeople love it because it successfully bridges the gap between a functional protein supplement and an indulgent candy bar, offering a familiar, tasty treat that feels less like a compromise. Its versatility makes it a go-to for pre-work fuel, post-exercise recovery, or a desk drawer emergency snack.
With 28.75g of sugar per 100g, it can cause a rapid blood-sugar spike, making it a poor choice for those managing diabetes or seeking low-sugar diets. It also contains common allergens like peanuts, soy, and milk. To counteract the sugar impact, pair it with a source of healthy fat or additional protein (like a handful of nuts) and consume it around physical activity when your body can utilize the sugars more efficiently.
The 'Marathon' brand name for this bar is used in the UK and Europe, while it is marketed as 'Snickers Protein' in the United States.
