Do you still feel the need to take thyroid while taking b vitamins? I feel like I’ve tried everything to increase body temp and bowel frequency except b vitamins. The amount of food allergies I’ve developed is alarming. Can’t eat grains, dairy, eggs, no fiber. Only things that don’t slow motility and cause severe stomach issues is juice and meat.Definitely B vitamins. Thyroid had a stimulating effect on motility in the beginning, but that quickly subsided.
