Seriously I tried a lot of things (kelp, herbs, minerals, vitamins) to support adrenals and thyroid and finally tried glandulars and they were way more effective. 'Adrenal Cortex Extract' by Nutricology and a Thyroid Glandular called 'Raw Thyroid' by Natural Sources.

I would really try glandulars if I were you. The ones listed above are both made from New Zealand free range bovine that aren't treated with hormones or anything like that.

The raw thyroid nearly instantly raises my oral temperature from 97 degrees to 98.6 and it makes me feel a lot better...whereas kelp and iodine give me symptoms and actually make me feel colder for whatever reason.
