Cytoplan Thyroid Support contains L-tyrosine, an amino acid. Amino acids are compounds used by the body for a number of functions including to make hormones and neurotransmitters (brain chemicals).

  • Seagreens® Ascophyllum nodosum is the organic kelp (a type of seaweed) species that we use in our product. It provides a natural source of iodine - iodine is one of the micronutrients known to be short in many people's diets. Iodine contributes to normal production of thyroid hormones and normal thyroid function
  • Seagreens® is a rich source of a range of minerals, vitamins, trace elements, amino acids, essential fats and antioxidants. Studies demonstrate Seagreens®’ nutritional value to be higher than seaweeds of the same species from the same location
  • Research shows that the iodine from Seagreens®is an ideal form which has a more prolonged and steady uptake than potassium iodide (the common form of iodine in table salt), with no adverse effect on the thyroid
  • Seagreens® carries Nutritious Food Seaweed BDA certification, which assures consumers of consistent nutritional value, levels of iodine, and is rooted in the principles of sustainable food and biodynamic production
