I just looked at the Vitalerbs formula. I noticed that it said the grasses were organic, and then lists the other ingredients. The unknowing may take this to mean that it is all organic. But that is not the case. So you are getting herbs that are not organic and from who knows where.
I use Dr. Schulze 's formula and make it myself from certified organic herbs from trusted sources. I need enough for my family and friends that is worth the investment to buy it in bulk and make it myself. Uny is a great source if you would like to purchase it.
If you really want to use the vitalerbs, I would buy the ingredients myself and make it up. Then you know what you are getting. I am sure the herbs are beneficial in a natural organic state. But it is different than Superfood, so unless you have a reason for not using Superfood- it is a great source of nutrition.
