Hey. I commend your initiative. I've not tried thyroid hormone but had about 30 hypo symptoms last year a TSH of 6 and t4 and t3 that were about 11 and 4.5. Not ideal. My antibodies were over 1000 and cortisol levels consistently low. Like you I did a stumbling in the dark process and after discovering also my vit d and b12 and iron levels were very low began a list of suppliments.
Vit d3 sublingual
Vit c (soluble without aspartame)
Iron - slow release
And started a simple protocol to repair adrenaks. Borage and licourice tincture morn and night in water.
For leaky gut - l glutamine powder in water when no food consumed for at least half an hour. Morn and night.
I waited 5 months for an endo appointment through nhs and also cut out gluten and wheat as fully as I could along with caffeine, alcohol, dairy and soy.
Started to cook with coconut oil and put it in smoothies. Kept eating regularly small light leaks with good protein that is clean organic where possible and upped my intake of whole foods.
AlSo removed regular perfume use and changed household cleaning products to green ones. As my oestrogen levels were a bit high too.
I say all this like I am a saint. I did have slip ups. Occasional coffees, a bite of pizza, odd glass of wine and forget some suppliments after receiving a powerful healing as I felt so good after!! But this was the general aim.
About 25 - 28 of those symptoms went. The dry shiny puffy hands, Brain fog, bloating, total exhaustion, dry skin. Red peeling face, v dry blurry eyes, broken nails, hair loss, super dry hair, stiff knees, back aches, constipation, double heavy periods, anxiety, depression. I still suffer cycles of worsening symptoms like dry hair, eyes and some tiredness but feel a whole lot better. These dips are more noticeable when I stray off the protocol or mid cycle.
The Endo eventually saw me and my recent panel and said she will not advise me to take thyroxin yet as the blood panel had improved. I'm not saying you shouldn't or I won't one day but I am doing my best to feel my way to better health with a holistic approach. Accupuncture and homeopathy didn't heal the antibody situation or symptoms but the healing certainly gave me an incredible energy boost and improvements that go beyond physical.
I'm not sure if there are ones on this list you'd like to add but make sure they are gluten yeast and filler free. Also you can take vit a and glutathione.
I don't think this protocol has to be for life. Just a real gradual health repair 6-12 months and then see where all levels are and moderate maybe to Multi pill if possible. Another thing is aerobic exercise or gentle exercise should be built in gradually - something I've not done any of but should snd this will help the oxygenation process and metabolism. Some would also say add coq10 and anti oxidant. What I do with those is alternate with some of the other less integral vits.
Drink plenty of filtered water. Distill out the chlorine if you can. Use a natural deodorant and soaps. Where possible. Do not bathe in highly chlorinated water.
Enjoy sunshine and make a great mental shift to step out of worry and anxiety. And do what you can to embrace the condition as a sign post to elevate your body's vibration - see it as a gift not a curse - though hard to some days!! Also change or remove any stressful or toxic relationships. The healing started that process for me automatically. There was a shift inside. This is also key to keep yourself and your healing process protected and optimised.
These imbalances in hormones and gut health take time so be patient and make good small steps. It probably took years to get out of balance so may take a year or two to rebalance but it's def worth trying a natural protocol in my opinion. The ENDO was pleasant and happy with the progress.
Sorry can't be more help on t3 opinion. I guess everyone has different reactions. I think you have intelligence in your body that you must listen to. It will usually tell you what's good or not - and that's a very personal journey. which is why this journey is widely experienced although many themes of help reoccur.
All the best - happy healing!
