If you are a vegetarian on the slimming world plan or you are looking to gain more muscle during your weight loss, you might be on the hunt for a low syn protein powder, but what about Protein World's slender blend, is it syn friendly?
Slender blend has around 7.5 syns on average no matter the flavour that you choose, making it very high in syns on the SW plan, we would suggest only having this protein powder in moderation to avoid using too many syns.

To find out more about the syns in Slender Blend, we've put together a small guide below which will cover why the Slender blend is so high in syns, some syn values and some low syn alternative protein powders from other brands.
At 7.5 syns a shake, Slender blend protein powder is very high in syns, this is because the powder can be used to replace meals as well as supplement protein in the diet, having up to 24g of protein a serving when mixed with almond milk.
We would recommend having these shakes in moderation since they use over half of your daily 15 syn allowances, we would also not recommend having them often to replace meals since they do lack nutritional content.
Slender blend has a wide range of flavours for their shakes, to help you out, we've listed all of their syn values down below.

If you find Slender Blend to be too high in syns or you are looking to change up your regular protein powder, we've got some great low syn alternatives for you to check out below.
To conclude, Slender blend protein powder is high in syns, having 7.5 syns a serving which is over half of your daily syn allowance, we would therefore suggest having this supplement in moderation, especially if you are using it as a meal replacement since it has little nutritional value.

There are lots of other low syn protein powder options like diet whey, with syns starting as low as 5.5 a serving if you are looking to maximise your protein intake.
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.
