The Spectra™ Superfoods Blend is a blend of phytochemical extracts from 29 fruits and vegetables. Phytochemicals are simply the active ingredients that promote whole body health. The extracts do not contain any of the source ingredients’ protein, fat, or carbohydrates. One can only be allergic to protein, so without it, the Superfoods Blend contains no allergens. The blend includes extracts of green tea and green coffee but does not contain any caffeine.
