@jeff0516161 welcome to the forum.
Firstly, not everything artificial is bad for you (most modern medicine is artificial / synthetic) and not everything natural is good for you (deadly nightshade is natural and organic but it will kill you).
We have spent a huge amount of time considering and testing sweeteners and we believe that sucralose is currently the best solution. It’s zero calorie, doesn’t damage teeth like sugar can, it is 600 times sweeter than sugar so you only need a tiny amount, and there is overwhelming scientific research that proves it’s safe. If you have a better solution I will certainly give it serious consideration.
Here is a list of all the sweeteners both natural and artificial that we have considered, all of which have pros and cons, there is no magic solution - http://www.sugar-and-sweetener-guide.com/sweetener-values.html
We also provide an unflavoured and unsweetened version which will allow you use your preferred sweetener.
As @omikes correctly points out there are very specific reasons why we use a synthetic version of b12 (an essential nutrient).
Vitamin B12 – As vitamin B12 is mainly found in animal products, and Huel is vegan, all of the B12 in Huel is added in our micronutrient blend in the form of cyanocobalamin. Although this form is artificial, other forms are either not as well absorbed by the body or are not stable in food products over shelf-life, so nutritionally cyanocobalamin is the superior form of B12.
Kind regards, Julian.
