No iodine in our spirulina
Spirulina is not seaweed and therefore doesn’t have any iodine in its natural environment. We replicate these conditions and do not provide any iodine in spirulina’s growth medium, leaving it completely devoid of iodine and therefore perfectly safe for people affected by thyroid conditions.
Seaweed sources of iodine
For those of you who are actively seeking iodine, as it is also an essential micronutrient that is particularly important for pregnant women to ensure infant brain development during pregnancy, do note that not all seaweed are created equal in the matter. Dulse (dillisk) and nori (the variety used for sushi rolls) are the most moderate sources, though still excellent as a few grams of those dried seaweeds in flakes will give you your daily requirement. Arame and kelp (also called kombu) are far more potent, to the point of having to be used sparingly. One gram of dried arame flakes will give you a few days worth of iodine where one gram of kelp could represent two weeks intake in a pop!
