Some energy drinks are syn free, such as red bull sugar-free, however, some with sugar can have up to your whole daily syn allowance.
To help you figure out which energy drinks are syn free we have composed a short guide below which will take you through which energy drinks are syn free, syn values of full-sugar energy drinks and whether or not energy drinks are healthy on the SW plan.

Energy drinks have a love and hate reputation in the diet world, they are often very high in caffeine and sugars (unless you get the sugar free versions) which can be damaging to your health when consumed in excess.

Other natural ways to get energy could be through black coffee and herbal teas which are syn free, you could also pick healthy foods such as carbs and dark chocolate to get an energy boost.

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.
