I have been on Levothyroxine for nearly 5 years, dosage of 75 mcg. Is is safe to drink soy milk when on thyroid medicine? I take my med at night when I go to bed and drink the soy milk in the morning at breakfast. The soy milk has helped lower my cholesterol significantly in the past year.

Wow, thats a question that I would have never considered. I am on Levo too and was never told to avoid any types of food or drink. I was told, though, to take it in the a.m.?

Am I misinformed?

If you get an answer, please, let me know.

There really isn't any food you need to avoid, but do take your medication at least 30 minutes before eating in order to maximize its effectiveness.

Soya can interact with the absorption of the thyroxine, so shouldn't be taken within a few hours. Have you tried rice milk? It's just as nice an a great alternative.

was told to take the med in the am and if can wait 1hr before anything to eat and wait 2 to 4 hrs and taking certain vitamins. something i will take up with a couple of my doctors to make certain. u know at least 3 imputs and then i take one of them and see if it works. i think a lot is kept from us by doctors who pharmaceutically practice and are tought to just mask symptoms instead of getting to the core of diseases and treating. I heard of a study that they take a group of thyroid, hoshi's, and other patients and give half of them a sugar pill and the other half actual hormones to see if mind over matter play a roll and get such 50/50 numbers that they don't have significant proof that these symptoms some people have aren't even there. they wanta make $ off the antidepressants then to get people to have control of how to deal and heal with there will of mind.

Prettysmile: Did you check with your pharmacist about drinking soy milk? Or you can look online to research the instructions for the prescription you are taking.

Since I usually wake to go to the bathroom sometime during the night and I take my pill then. That way when I get up for work I can eat my breakfast without worrying about compromising the drug.

I was told simply to take it in the morning and not to eat/drink dairy for about an hour after. Otherwise, you can eat and drink all foods, including dairy, 100% percent of the time.

Hi Prettysmile,
There are some foods that are considered "goitrogenic."  They can promote goiters and
result in hypothyroidism by reducing the amount of iodine in the body that is available to
help synthesize T4 and T3.  But they seem to only present a problem when eaten raw and
in large quantities.  Some of the more common goitrogens are raw cruciferous vegetables
such as broccoli, cauliflower, brussels sprouts and cabbage, and kale, turnips, soy and others.
Soy products can be a problem but only if eaten in excess. I have read that 1 to 2 servings of
soy a day should not cause thyroid problems.

Hi I have had a under active thyroid problem since I was 14 on 150mcg

I never knew I should avoid dairy and food for a hour after taking thryroxine ! In fact to boost dairy I would drink a large glass of milk to take them !!!!

I knew that iodine is not good for thyroid so was told o avoid Brockoli , cauliflower ... The others I didn't know !!! I love peanut butter but was told not to eat because it is goitrogenic Oh no !!!

A full list would be good to know

I've been on Levothyroxine for 11 years and always take it in the morning. I was never told about the non-eating timeframe. Maybe that's why I've recently had to up the dosage. I'll be more careful about when I take it. What vitamin/mineral supplements interact? I usually take all my "pills" at once.

Mary Shomon has an informative article about how to take thyroid medication and
possible interactions with other drugs, supplements and food. I think it will answer
a lot of questions:
