How to check my temperature for Hypo

Hi all,

After a year of being shuffled between the Endo team and my GP, I finally saw a great Doctor on Friday. He did not just look at my blood test results but but he listened to me and after our long discussion, he told me he wanted to put me on a very low dose of Armour Thyroid 30mg, asked me to take some Kelp supplements (3 times a day) and Tyrosine 1 gramme daily. But before I start the treatment, he asked me to take my temperature every morning after waking up. Now, normally when I sleep, cause I feel cold all the time, I cover myself in heavy blankets and duvets and my question is, will this affect my temperature readings if I take the temperature when am just getting out of bed? or do I need to get up, brush my teeth and then come back and take my temperature? Yesterday when I did this, my temperature when I was in bed was 37.1, after I went to the bathroom and came back, it went down to 36.8. Please advise, thank you. Also, in the UK, which is the best Kelp brand and Tyrosine brand?

Hi julia35, you need a good "Basal Temperature Thermometer", there are many on Amazon. You need to take your temperature on waking, that is BEFORE you get up or eat or drink anything, (do this for at least a week). Being covered in blankets/duvets should not affect your temperature, I have woken up feeling very hot, but my temperature was still below 35 degrees Celsius.

I don't know if the supplements you mentioned are appropriate, I'm sure someone else will comment.

I don't know about the second and third product but think it's great you've been given Armour.

Before blood tests were introduced that's how we were diagnosed, if we had a low temp and/or low heart beats plus other clinical symptoms.

Broda Barnes, now deceased, introduced the Basal Temp Test and his site still helps people. Annie has given a perfect response re taking it. This is also a link to the Barnes Institute just for info. It says:-

I wish you success in your treatment.


Thanks Shaws, will check the link


I always feel cold too even my temp my go up to 36.8 after ovulation.

Is your body temp fluctuating between periods?


Hi Justina, I only started checking my temperature yesterday so will check and see.


Hello julia35,

Great to be prescribed Armour. Lets hope it is your answer.

Both of the suggested supplements are controversial and should only be taken when directed by an experienced practitioner as both inhibit thyroid hormones if taken in the incorrect amounts.

However, your doctor appears to know what he is doing ...I just wanted to make you aware.


L-tyrosine is an amino acid necessary for the manufacture of thyroid hormones and can be taken alone or as a component of a nutritional supplement at a dosage of 500 mg per day to enhance thyroid function.

Iodine (in Kelp)

The thyroid gland needs iodine to make its hormones. Too little can cause impaired thyroid function, while too much can actually interfere with the thyroid's ability to produce hormones. The dosage range for iodine supplementation is 300-400 mcg daily. Read the labels on your multivitamin and any thyroid preparations you are taking to make sure your total intake is within recommended range.

I think the taking of your temperature is really good way to monitor your progress.

Thank you


Do you mind me asking who you saw & whereabouts? Also what your blood results were?

I'm having trouble getting diagnosed too, bloods come out within range but a bit wonky. I've got a private appointment lined up at the end of the week. Would he interested to hear your experiences/journey. Message if easier x
