Our algae preparations “Spirulina 400”, “ChlorellaPur”, “Chlorella Pur C plus”, as well as our omega-3 preparations, contain only very small amounts of iodine (max. 1.6 µg iodine per capsule) and can therefore also be taken if you follow a low-iodine diet. The German Nutrition Society recommends a daily intake of 200 µg iodine for healthy persons between 13 and 51 years of age. Over 51 years, 180 µg is recommended.
