J2O is a childhood favourite drink for many of us and has been around for a while, but is this sugary drink friendly to have while on the slimming world plan? Or is too high in syns?

J2O has relatively low syns, it has on average 3 syns per bottle, making it a great low syn drink to have on the plan as an occasional treat.
We've composed a syn guide below which will discuss how many J2O's you can drink on the SW plan, syn values of J2O and some low syn alternative drinks to have as a treat.
At 3 syns per bottle, you can drink up to five J2O's on the slimming world plan before using all your 15 syn daily allowance on the plan.
J2O drinks are low in syns since they mainly consist of fruit, but they are very high in sugar, having 11g of sugar in just one small bottle, we, therefore, suggest having these drinks in moderation.
J2O has a wide range of drinks on offer with similar syns no matter the flavour, we've listed their syn values below to help you out.

If you find J2O to be too high in syns and sugar, we've got lots of other alternatives for you to check out below.

Overall, J2O is low in syns, having 2.5-3 syns on average for a small bottle, meaning you could have up to 5 in a day before using all your 15 daily syn allowance on the plan.
We would however suggest drinking drinks like J2O's in moderation since they are very high in sugar or choose zero sugar drinks which are syn free to save calories.
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.
