If you are looking for a sweet snack, or maybe you fancy some marshmallows with your hot chocolate, you might be wondering how many syns marshmallows have.

Marshmallows on average have 1.5 syns per marshmallow, this can change however depending on the size of the marshmallows, with mini marshmallows having fewer syns.
We've put together a short guide below which will take you through how many marshmallows you can eat in the slimming world, some syn values as well as two recipes for making your own SW marshmallow bars!
At 1.5 syns per marshmallow, you could have up to 10 marshmallows before using up all of your 15 syn daily allowances, making them a great low syn sweet treat.
Marshmallows are low in syns since they are mainly just made of air, but you should still eat these sweets in moderation since they are high in sugar having up to 16g for an average 25g serving. Alternatively, you can have sugar-free marshmallows which are healthier and still low in syns.
Marshmallows all have a similar syn value no matter where you buy them from, but their values can differ according to the different sizes.

Syn values are calculated using a formula based on calories, saturated fat and sugar content per serving. They’re not the same as calories — a product can be low in calories but higher in syns if it’s high in sugar or fat. Always check the official Slimming World app for the most accurate and up-to-date syn values.
Yes. When manufacturers reformulate their products, the syn value can go up or down. This is why we recommend double-checking with the Slimming World app or your consultant, especially if a product’s packaging has changed recently.
Most Slimming World members work with 5 to 15 syns per day. Your consultant will advise on the right amount for you. The key is to use your syns on the things you enjoy most — whether that’s a chocolate bar, a glass of wine, or a packet of crisps.
