Has anyone considered adding a green superfood powder to the mix to really boost essential vitamins and minerals? There are a couple out there that I am considering using, and there are reviews of them there on this site http://www.naturalnews.com/022753_food_superfood_taste.html
The one that I am considering adding to my soylent recipe is Vitamineral Green, the nutritional density is reviewed as outstanding. Beware though… very few people enjoy the taste of wheat grass, and many of these powders have some bite, especially Vitamineral Green. More mild flavored ones like Amazing Grass might be more suitable for those with a more sensitive palate.
Currently, I dial back a tiny on the maltodextrin, a few minerals and vitamins in my mix and add a small amount fresh fruit juice instead. It really does help boost the taste.
