To the best of our knowledge, our bulk herbs, tablets, and food items are free of gluten, soy, and dairy. The machines used to powder the herbs are only used to powder herbs and spices.
However, we work with dozens and dozens of small farms and it is likely that some of them would be growing nuts, barley, oats, and wheat. The machines used are all certified according to NOP and EU organic regulations regarding clean downs, batch to batch documentation, and so on.
We do offer two liquid extracts—Focus and I Travel Well—which are made with organic glycerin and may contain a small amount of soy.
