Is this protein drink okay to drink while on levo?

Is this protein drink okay to drink while on levo?

I'm kinda new to being hypo. I take 25mcg levothyroxine. I also like to drink my protein drinks to give me the protein I need because I'm underweight, but I'm gaining weight back slow and steady again. Is this drink okay while on this medication. Some people tell me that it can cause heart problems and etc from to much. I wait at least 4 to 5 hours to drink it .

Toriowens, it contains soy protein which isn't recommended for those with thyroid problems and soy can affect uptake of Levothyroxine. I would advise finding a brand without soy or making your own protein shakes.


Yes, soya is not good for you. Don't take your meds with milk either. I take my levo at night so nothing interferes with it. X


As far as I'm concerned, this drink isn't fit for anyone at any time!

It contains

- corn syrop - very bad

- soy protein - causes cancer, an endocrine disruptor, and interfers with thyroid hormone uptake by the cells

- canola and sunflower oïl - bad fats

- processed cocoa - which means it has no nutirents left

- carrageenan - which can cause diarrhea and other unpleasant things

- and all sorts of additives and synthetic vitamins.

I wouldn't be at all surprised if it caused heart attacks. Sounds like a recipe for disaster to me! lol

I take Natural Whey by Reflex as recommended by my adrenal specialist, yes it has soya lecithin which is outweighed by the carefully selected ingredients with no artificial nasties it has 78% natural protein carefully sourced, added digestive enzymes and probiotic spores, as a fitness expert to many top athletes I would think this is a well thought out product.


I agree with clutter and greygoose, People who have thyroid problems should not take soy. "Soy falls into a category of foods known as goitrogens -- vegetables, grains and foods that promote formation of goiter -- an enlarged thyroid . Some goitrogens also have a definite antithyroid effect, and appear to be able to slow thyroid function, and in some cases, trigger thyroid disease."(

The article also states that researchers of the Food and Drug Administration argued against the approval of soy by the FDA and they cite a study that they did. (For the American FDA system to state that something isn't healthy, it really, really needs to be unhealthy) :)

Notwithstanding soy, greygoose points out the other harmful ingredients in this protein drink.

You will have to do your research to find one without soy and other harmful ingredients (I haven't been able to find one) or make your own.

Good Luck
