NEW: Pro Iodine by TISSO – with natural iodine from marine algae

Iodine is a trace element that is essential not only for the thyroid, but also for a number of other organs. Marine algae are the richest source of iodine in nature. We have harvested the best of two kinds of algae for you. Pro Iodine contains valuable natural iodine obtained from North-Atlantic Seagreens® Ascophyllum nodosum (Knotted wrack seaweed) – combined with high-quality astaxanthin, harvested from the freshwater microalgae Haematococcus pluvialis.

The essential trace element iodine is important for:

  • the production of thyroid hormones and a normal thyroid function
  • a normal energy-yielding metabolism
  • a normal cognitive function
  • a normal functioning of the nervous system
  • the normal growth of children
  • the maintenance of normal skin

Seagreens® Ascophyllum nodosum and Haematococcus pluvialis: our perfect algae duo

Iodine is an essential trace element. The body only needs relatively small amounts of it. (A comparison: According to the German Nutrition Society (Deutsche Gesellschaft für Ernährung), a healthy adult requires about 200 micrograms of iodine a day; the body needs 110 milligrams of vitamin C a day, 550 times more.) However, it is not able to produce this small amount itself and must take it up from food.

And this isn’t so easy. Iodine is mostly to be found in the world’s oceans, whereas soil has very low levels in comparison. Fruit, cereals and vegetables do not, therefore, contain any significant amounts of iodine. Through the addition of iodine to animal feed, animal food – such as eggs and milk – now contains a significantly higher proportion of iodine than it used to.

However, marine algae and marine fish are by far the greatest sources of iodine.

Knotted wrack seaweed Seagreens® Ascophyllum nodosum

The North-Atlantic Seagreens® Ascophyllum nodosum stems from an ecologically sustainable wild source and has specifically been checked for heavy metal contamination (certified according to the Nutritious Food Seaweed Standard).



Haematococcus pluvialis microalgae

Haematococcus pluvialis is a freshwater microalgae that is mainly found in small water bodies. It is one of the most important natural sources of astaxanthin – a carotenoid responsible for the red hue of crustaceans that feed on these algae.

With the help of astaxanthin, Haematococcus pluvialis can survive even in extremely adverse conditions. When there is a lack of water, nutrients or overly intense sun rays, the algae that are actually green switch off their photosynthesis and go into resting mode. They produce large amounts of astaxanthin in order to protect themselves from UV light and oxidation.

Top quality and safe raw material origin guaranteed
All algae raw materials used in Pro Iodine are subject to stringent quality and contaminant controls.
