There are quite a few to choose from but as a starter it is best to choose a broad spectrum product such as Cytoplan’s Cytozyme* (£20.15 for 60 caps), Viridian’s High Potency Digestive Aid* (£7.45 for 30 caps or £17.10 for 90 caps), BioCare’s Spectrumzyme* (£24.95 for 90 caps) or Nutri’s Similase (£11.42 for 42 caps or £20.75 for 90 caps). All of these are vegetarian and three are vegan*. You have the added ethical standpoint of Viridian along with their food blend of spirulina, alfalfa and bilbery. The only contra-indications with these are if you are pregnant or breastfeeding as there haven’t been enough trials done. Care is also recommended if you have been diagnosed with ulcerative colitis.
