My gut got ruined once by antibiotics and kefir got it working again really quickly. All it takes is getting some kefir grains (from a friend or on-line) and milk, and it is the best probiotic I know of. You can also enable your thyroid gland to produce high quality T4 and T3 by supplementing with iodine and selenium. The thyroid hormones are made from iodine, selenium is used by the thyroid to regulate the production. Without supplementation of these things it is likely that the iodine receptors in your thyroid can't scavenge enough iodine so they grab onto anything close and fill up with other members of the halide family like flouride, bromide, etc. which directly reduces production and high quality T4 and T3 output. These hormones are required for the body to maintain homeostasis and healthy cells. This may resolve several of the listed issues.

editing to add a thought. You can get your iodine eating beefsteaks, and your selenium from brazil nuts if that is preferred to using supplements..
