I've been putting 2 tb spoon of flaxseed in my oatmeal to help my hypothyroid. now i've read flaxseed hinders underactive thyroid. what's true?

May hinder if raw: This is a complex issue without an easy answer as flaxseed does contain goitrogens (chemicals that can inhibit thyroid function), though most of are inactivated by heating them. Taking dulse and a mineral supplement at a different time helps. See http://autoimmune-paleo.com/goitrogens-why-you-dont-need-to-avoid-them/ There is VERY conflicting info on whether flax oil is beneficial- see comment:
