You’re absolutely right! The Flavour Boost samples are 3g, and a teaspoon is listed as 4g.
Remember, these are samples, we don’t want people to just buy loads of these and use them continuously. By having a slightly bigger than normal sample (1g more), it gives people the best opportunity to experience the flavour. If we included 2g and someone added this to 125g of Huel (instead of the recommended 3 scoops) they would be getting less flavour and therefore won’t get the full impact. If the flavour is too strong, no worries - just add more water!
If the flavour is a little too strong you will still know whether you like it or not. You can then go on and purchase a full pouch and add as much as you like!
I hope that makes sense, there is method to our madness!
