The current beta software takes nutrient values from the USDA database. The USDA database is missing values for Taurine, Iodine, Biotin, and Chloride. We have added the chloride values and are adding the taurine, biotin, and iodine values for the next update. We are also expanding our nutrient database sources and will be using databases from around the world.
In the meantime, please use supplements to fill in the any gaps in the following nutrients: Taurine, Biotin, and Iodine. An inexpensive source of iodine is kelp powder. Taurine can be purchased as a powder as well.
