Fucus Fucus is a brown alga rich in mucilages, minerals, such as sodium salts, potassium and magnesium; trace elements, particularly iodine (0.1%), and also cobalt, zinc, nickel, chromium, silicon, etc. Finally, it is a good source of nitrogenous matter and vitamins A, B1, C and D. Slimming properties are attributed to it due to its high iodine content, stimulating metabolism through the thyroid; and for its mucilage content, which, in contact with stomach and intestinal fluids, forms a viscous and very voluminous gel that increases the volume of feces, promoting peristalsis, exerting a satiating effect and hindering the absorption of sugars and fats. . Directions for use Take 2-3 tablets three times a day, between meals. Warnings: Not recommended in case of hyperthyroidism, esophageal or intestinal obstruction, and unknown abdominal pain. Do not use during pregnancy or lactation due to its high iodine content.
