This is what I've found so far, and it's not much. Some of the sources are questionable.

Excerpt:
"Flaxseed is a cyanogenic goitrogen, which means it contains a substance that converts to thiocyanate in the body. Thiocyanate effectively blocks iodine concentration by the thyroid gland and thus causes thyroid dysfunction.
Flax is also a rich source of lignan, a phytochemical which converts after digestion into a phytoestrogen-like substance. Phytoestrogens are known to suppress thyroid function."

" I'm sorry we do not have much information on flaxseed meal and the effects on the thyroid gland. The only information we have been able to obtain is from the Flax Council of Canada. In a book labeled "Flaxseed, Health, Nutrition and Functionality", there is a paragraph that has a mention of the Thyroid gland. It is labeled under Cyanogenic Glucosides. Here it is in its entirety.

'Cyanogens are natural toxicants that occur in foods like lima beans and cassava as well as in flaxseed. In the body, they are hydrolysed to release hydrogen cyanide which is rapidly converted enzymatically to thiocyanate (SCN). SCN is also a breakdown product from glucosinolates in common vegetable like cabbage and rutabaga. SCN inhibits the uptake of iodine by the thyroid gland and, at high levels in the blood for a sustained time when iodine intake is limited, goiter
can result. This hazard is offset where iodine consumption is adequate.


In Canada, table salt has been iodized since the 1930's to eliminate endemic goiter in inland regions where dietary iodine was inadequate. The addition of iodine to table salt is required in Canada and is permitted in the United States. We are not in a position to make nutritional or dietary recommendations for any medical condition. We suggest that you consult your doctor on this specific subject concerning our product.'

Thyroid Meds and Flaxseed/Psyllium

Bought the books yesterday and about to start the plan...I am very excited. May have one issue though...I thought I read somewhere in the book that flaxseed oil and psyllium can effect the absorption of thyroid meds. I was diagnosed with hypothyroid in early May and take levothyroid and T3 slow-release. My doctor told me to take vitamins and supplements at night and my medication in the a.m. as to not effect the absorption. How are you suppose to take the LLC twice a day if you have to wait several hours after taking thyroid meds. I appreciate any insight. Thanks -

Hi There Stacy and Welcome to The Forum!
To comply with your doctor's recommendation, I would suggest that you consider taking your LLCs in the mid-afternoon and sometime before bed. Good luck to you on your Fat Flush journey!

Iodine and Thyroid Function

Iodine is vital for good thyroid function, which in turn is essential for health. … In adults low iodine intake (or very high intakes) can cause hypothyroidism.

<snip>
Low zinc intakes exacerbate the effect of low iodine intake. Some otherwise healthful foods contain goitrogens - substances which can interfere with iodine uptake or hormone release from the thyroid gland. These foods are generally only a concern if iodine intake is low. Consumption of brassicas, such as cabbage, Brussels sprouts, broccoli and cauliflower, increase the requirements for iodine, especially if consumed raw. Soy beans, raw flaxseed, cassava (used in tapioca), sweet potatoes, lima beans, maize and millet also increase the requirements for iodine.
