Help needed for supplements

Hi. I’m on levothyroxine 3 days at 150mg and 4 days at 125mg. Wanting to try something to help convert the main T one. Also can anyone recommend supplements to take wether it be cortisol, melatonin, zinc something for adrenal glands. Our doctor and hospital won’t give out anything other than meds for anything else.

I have been put on metaformin for diabetes, and meant to have started one for BP.

Please please please any advice very welcome

Metmorfin depletes the body of B12 and magnesium and develops lactic acid in the body.

If you have not had your B12 tested, best to ask your GP to do so as soon as possible to assess your blood levels as you may need injections.

Have they checked your thyroid anti-bodies and tested you for pernicious anaemia? If one existed, the likelihood for the other one to be present is also possible.

You can start by taking 400 mg of Magnesium. There are different magnesium salts out there best to look for magnesium glycinate or bisglycinate as it is highly absorbed.


Taking Omega 3 also will help in clearing the lactic acid from your body. Take 2 x1000 mg of Cod Liver oil. Cod Liver Oil also contains what you need as Vitamin A. Research has shown that Vitamin A depletion could be the trigger for type II diabetes.


Insulin needs zinc to be stored and to be released from the pancreas and is required for carbohydrate metabolism. You can safely take 15-25 mg daily without upsetting your ferritin and copper levels. Speaking of which, they also ought to be tested on a regular basis with diabetes, as you may tend to have an overload stored in your liver and your body cannot get rid of.

Finally, a good dose of Vitamin C of 2000 mg will help also a great deal to clear the free radicals that are created by Metmorfin.

I hope this helps for now!



Lots of helpful replies after your post of two months ago. So you are now on Metformin - what other meds are you taking in addition to the Levo ? What supplements and how much are you taking ?

I’m currently not taking any supplements so I’m going for private bloods to be done next week and will post results here.

I must look back on the last comments and see what I can do. Thanks I listed the medication I’m on below

This is an excerpt and hypothyroidism can cause blood pressure:-

Thyroid problems. When the thyroid gland doesn't produce enough thyroid hormone (hypothyroidism) or produces too much thyroid hormone (hyperthyroidism), high blood pressure can result.


Some people cannot convert levo sufficiently. Has your doctor tested your Free T4 and Free T3 and if you read the reason on the following link maybe he wll test these for you. If not you can get a private test:-



I’ll definitely look inti it on Monday. Sorry for late reply I took quite sick for a few day.

The doctor only tested tsh and t4. Says the other ones are irrelevant. My ferritin is low and they have me on folic acid. Once I get tests done privately I’ll post them here. Thanks for help


Have you booked your Private Tests ? Your GP is wrong to say the other tests are irrelevant. How do you know you have Hashimotos without testing the anti -bodies ? How do you know you are converting the T4 you are taking into the ACTIVE thyroid hormone T3.

Guess he would rather keep you unwell and keep prescribing endless drugs you would not need if your thyroid was correctly treated.

That’s exactly how I feel. They constantly put down anything I suggest from reading on here and put me on meds for everything under the sun. I went to nurse for blood other day but only u and e. And they want me back on Tuesday.

However I’m in the process of filling in the checkout for blue horizons. They haven’t confirmed Hashimoto or converting t4 correctly. But even hospital said they only work on t4. I asked my doctor if they only treat for that is there any point in me paying for private bloods and she said it wouldn’t do any harm. They can see what it say.

I’ve ticked the box saying I want blue horizons to explain results. Then I can head to doctor with it. And see from there.

Does a person need medication for Hashimoto.

You are already on the medication for Hashimotos - which is an auto-immune issue whereby the anti-bodies are attacking your thyroid. Taking Levo is the treatment but if you have anti-bodies people will suggest several things for you. You really must start reading up on things ... see the link below to the website for this Forum ....


When you receive your Blue Horizon results post them here for comment - in a new post :-)

Which tests have you requested with Blue Horizon ?

Here's some good info. I had to get private tests done for deficiencies, and I was very surprised by my results. Why had no one told me before that people with thyroid disease are often low in zinc, and zinc is key to converting t4 to t3?!

Bp tablet


Effexor xl




Quinine sulphate


All for different reasons. When they put me on the bp one I told them I didn’t want it. I wanted off them all as I believe they’re giving me meds for each individual thing rather than the actual one.

I have diabetes high bp and cholesterol

Depression under active thyroid and fibromyalgia.

I’m sick of being constantly tired and sore.


Are you posting with two different names - ? - confusing 😊


I don’t know how that’s happened. I must have already had an account and forgotten about it. I do get two emails every morning. So that’s would explain it.

Depression can be due to low T3 as can fibro.

The doctors fail to know or understand that levothyroxine (T4 only) has to convert to sufficient T3 for us to function normally and help relieve all symptoms. If we don't convert (levothyroxine) T4 (inactive) into T3 (Active) we cannot function.

I am not medically qualified but it looks to me as if you have individual symptoms treated instead of the thyroid gland. T3 is required in ALL of our T3 receptor cells.

Also we can get digestion problems due to hypothyroid sufferers having low stomach acid so most of us take digestive enzymes with meals as acid is required to dissolve food. Whereas we are apt to get prescribed meds which reduce the acid.

Statins are prescribed for high cholesterol. High cholesterol is a symptom of hypothyroidism and it reduces when we are on an optimum of thyroid hormones.

We have to read, learn and ask questions if our health isn't going to be ruined altogether. Many of prescribed medications can have side effects which we do not want.


The following is re BP.



All that you’d are saying to me makes seance. And I put this to the diabetic nurse last week when they pushed for me to take the bp tablet. She said out of all the meds I’m on those would be the ones she’d recommend to take above all other medication.

She mentioned the autoimmune system and it all related as I had been reluctant to start them but yet they won’t look into it further.


The medical profession seem to be the most poorly trained in such a common and widespread condition. Unfortunately they name the symptoms as 'individual' conditions and not collectively.

Ask doctor to give you a Full Thyroid Function test as you've been recommended by the NHS Choices for information and advice - Thyroiduk.org.uk and due to your symptoms you could be undiagnosed hypothyroid.

The appointment has to be the earliest possible, fasting (you can drink water) and if you were taking thyroid hormones (levothyroxine) you'd allow a gap of 24 hours between last dose and test.

Ask doctor to test TSH, T4, T3, Free T4, Free T3 and thyroid antibodies. FT4 and FT3 are the most important but these are rarely tested.

Also test B12, Vit D, iron, ferritin and folate.

Get a print-out from the surgery (some charge a nominal sum for paper/ink) and put the results on a new post.


These I have asked for time and again which the refuse to do. I’m going to use blue horizons and get tests done. I’ve been under active thyroid for more than ten years but even increased levothyroxine there’s still no improvement in how I feel.


Yes, you're wise to get these done and doctors etc are told only a TSH and T4 are required which is ridiculous and we're all in this mess together and I believe if we remain undiagnosed it is due to a yiatrogenic mistake (unknowledgeable). Yiatrogenic means:-

Due to the activity of a physician or therapy. For example, an iatrogenic illness is an illness that is caused by a medication or physician.

Members will help you to get better, so don't worry. Just follow the advice of how/when to get blood tests etc and slowly you will begin to improve. Some people need T3 to be added to T4 but now doctors have stopped prescribing but members have sourced their own.

I’m glad that’s the case.

I presume T3 is available to buy over the counter or online. I had asked my doctor about it. And yes u guessed it. They word prescribe it for me.
