Safe for thyroid: While there is some concern that chemicals in cruciferous vegetables can inhibit thyroid function no one knows how much & it appears only massive doses would have any adverse effect on the thyroid. The benefits of these compounds seem to far outweigh any risk. However, i think it is better to eat cruciferous veggies than rely on supplements. See http://bit.Ly/1axerlk & http://bit.Ly/1906qr6.
