These were recommended to me at my Slimming World group and I wasn't disappointed. I tried several flavours and they were all excellent without the chemical overtones you get with some other brands. Easy to use and very strong so only need a few drops for each use.

The coconut one is particularly good in yogurt.

I bought the white chocolate, Choc and hazelnut and the hazelnut. White choc tastes nice in Greek yogurt. The flavours with hazelnut was off putting for me personally but then I tried them in ice coffee so may taste better in food. Going to try the fruit flavours next

Yogurt 

Amazing to add a slight sweetness for baking. Unfortunately not sweet enough for me personally.

I have 6 different flavours & use them to mix into vanilla flavoured protein powder to make a range of interesting protein drinks. I also mix them with natural yoghurt to flavour the yoghurt when adding to puddings as well as mix into cake baking mixtures to flavour muffins, sponge cakes etc, They have many uses & some are better flavours than others as a couple I've found a bit synthetic tasking. I love the white cholate, mocha, toffee and blueberry flavours. They're a cheap & low fat way of getting flavour into low fat products ie. flavouring natural fat free yoghurt instead of buying ready-made flavoured yoghurts which always have tons of sugar in.

I have a whole host of flavours. I use them in yoghurt, cream, water and for a treat with vodka and crushed ice ( I particularly like strawberry or mango for this) also good in gin.

Love these flavours drops but some of them are very artificial tasting I’ll write ratings for the few I’ve had so it helps others who can’t decide. Cheesecake 10/10 I absolutely love this flavour in my oats and Greek yoghurt it’s a total game changer with out the sickly o er bearing sweet flavour . White Chocolate 8/10 I really like the taste  (subtle) not to strong or sickly I have it in oats yog and iced coffee. Toffee 8/10 nice flavour not to strong good for oats Greek yog and coffee. Butter Biscuit 7/10 I got this as toffee wasn’t available it’s ok but doesn’t have the same flavour as the toffee I’ve had it in my oats. Vanilla 7/10 this is a good plain flavour for oats coffee Greek yog and I even put 2 drops in my Tea it just gives it a littl sweet flavour to its giving up sugar,  but can be over bearing (artificial) if you use too much . Coconut 2/10 very disappointed I love coconut and thought this would be lovely in oats a yog but nope absolutely disgusting and artificial tasting.  Blueberry 2/10 same as coconut horrible and very artificial tasting .

I absolutely love this product and use it in my nutrition studio 7 days a week as does many other studios. We only wish all the flavours were available in Australia again.

Excellent I can't rate these high enough, so good 👌

Amazing! Although it comes in a small bottle this little beauty packs a punch! This is a great healthier alternative to curb your sweet tooth & give your pudding a satisfying taste.
