I can understand that you would like some information about the main differences between Bertrand and Jake, as we share the concept of complete food: food that contains all the nutrients that you need.
As Daniel already points out below, there are different aspects on which you can base your choice. An important one to start with would be taste, for me. I have to say that I have never tried Bertrands products, so I cannot say a lot about it personally. But, objectively, I see that while we offer the flavours banana, forest fruit and oaty vanilla, Bertrand offers vanilla, bilberry and apple. Texture can play a role as well though.
If we take look at composition, there are some differences. It seems like Bertrand overshoots some vitamins and minerals here and there, probably because they need to come from their organic ingredients, as that’s their vision on complete food. Which would likely be fine, but you could take a look at the different micro’s to find out for yourself. There are some more differences in composition (amount of macronutrients for example) between the products, but it might be a bit too much to point them all out here. You can compare the nutritional values here for Bertrand and here for Jake.
An important aspect of Jake, for me, is convenience. Which is why I like that the shakes are packed per meal. As NXS pointed out, base your choice on the criteria that you find important in a product. And don’t forget to always listen to your body and choose a product that makes you feel good. We definitely believe Bertrand does a nice job as well. Actually, as Daniel already said, consuming both if you like both is not a bad idea at all.
