Actimel is a great health drink to add to your daily diet on the slimming world plan, full of beneficial bacteria for the body and vitamins for immune support, but does this drink have syns on the slimming world plan?

Actimel has on average 4 syns for one multifruit immune drink, making it pretty high in syns for a small portion, therefore we would recommend having these drinks in moderation at just one a day.
In our guide below, we will discuss why Actimel is high in syns, syn values of actimel and some low syn alternative health drinks from other brands.
At 4 syns for just a small 100g bottle, you might be curious as to why Actimel Danone drinks are so high in syns, allowing you to have up to 4 before consuming all your daily syn allowance.
Actimel gets its syns from mainly the sugar and flavourings, with the average Actimel having up to 13g of sugar for a very small portion and around a gram of fat.
This is not to say you can’t enjoy an Actimel on the slimming world plan however, they are a very healthy way to spend 4 syns since they are full of health benefits like vitamin D and B.
To save syns we recommend switching to their 0% fat version which only has 1.5 syns a bottle.
Actimel yogurt comes in a few different flavours and types, as well as non-dairy versions, so to help you stay on track we’ve listed their syn values down below.

If you find Actimels to be too high in syns and you're looking for a low syn alternative, we’ve got you covered with our list of low syn health drinks below.

Overall, Actimel immune support drinks can be high in syns depending on the type you pick, for example, their full-sugar and fat multifruit versions have up to 4 syns while their low fat no sugar have as little as 1.5 syns, these drinks are a healthy way to spend syns no matter the type you choose, however.
Actimel is one of several probiotic yogurt drinks available, but how does it compare on syns? Here's a full breakdown:
| Yogurt Drink | Serving Size | Syns per Bottle |
|---|---|---|
| Actimel Original | 100ml | 3 |
| Actimel 0% Fat Original | 100ml | 2 |
| Actimel Strawberry | 100ml | 3.5 |
| Actimel Multifruit | 100ml | 3.5 |
| Actimel 0% Fat Strawberry | 100ml | 2.5 |
| Yakult Original | 65ml | 2.5 |
| Yakult Light | 65ml | 1.5 |
| Benecol Yogurt Drink Original | 67.5ml | 2 |
| Benecol Yogurt Drink Light | 67.5ml | 1 |
At 2-3.5 syns per tiny 100ml bottle, Actimel is relatively expensive syn-wise for what you get. The bottles are small and unlikely to keep you full. If you're drinking one daily for gut health, that's 14-24.5 syns per week — nearly a full day's syn allowance. You need to decide whether the probiotic benefits justify the ongoing syn cost.
Fat-free natural yoghurt is Free on Slimming World and contains live cultures similar to Actimel. Brands like FAGE Total 0% and Muller Light are popular syn-free choices that support gut health without costing any syns. You can also boost your gut health with Free foods like sauerkraut, kimchi, and fermented vegetables. If you specifically want a probiotic drink, Yakult Light at 1.5 syns or Benecol Light at 1 syn are more efficient choices.
If you enjoy Actimel and want to keep drinking it, opt for the 0% fat range to save 0.5-1 syn per bottle. Consider having one every other day rather than daily to halve your weekly syn spend. Some members freeze Actimel bottles for 20 minutes to create a thicker, more satisfying yogurt-like treat that feels more substantial.
For low-syn drink alternatives, consider flavoured water, diet fizzy drinks (all Free), or making your own smoothies with Free fruit and fat-free yoghurt. If it's the sweet, creamy taste you crave, a Muller Light yoghurt pot is Free and far more filling than an Actimel bottle. Check our low-syn desserts guide for more satisfying sweet treats.
No, Actimel is not Free on Slimming World. Even the 0% fat version costs 2 syns per 100ml bottle. The sugar content in Actimel drinks means they must always be synned.
From a syn perspective, Yakult Light at 1.5 syns per bottle is better value than Actimel at 2-3.5 syns. Both offer probiotic benefits, but Yakult Light gives you gut-friendly bacteria for fewer syns. The best option overall is Free fat-free natural yoghurt, which also contains beneficial cultures.
You can, but it adds up. A daily Actimel Original costs 21 syns per week. Most Slimming World members get 5-15 syns per day (35-105 per week), so a daily Actimel represents a significant chunk of your allowance. Consider alternating with Free yoghurt instead.
There are no branded probiotic drinks that are completely Free on Slimming World. However, plain fat-free natural yoghurt is Free and contains live active cultures. You could blend it with Free fruit to make your own probiotic smoothie at zero syns.
