I have symptoms of low thyroid. Gaining weight very easily, almost weekly. Cold sensitivity, hair loss, dry skin, brain/memory fog, heavy periods,. Almost like a like switch since I had my last child 10 years ago. My prescribed thyroid meds, but I d rather treat with diet changes if possible. Is that even possible.? I take a sleeping mineral at night to try to help with sleep. It has Calcium, magnesium, and zinc. Does that affect anything?
