Our  shakes can be used with synthroid. We have many people on  our shakes  that have over active, in active, and surgically removed  thyroid.

There is  a lot of misinformation and confusion about soy in the  marketplace  today. In countries where consumption of soy is high (like  Japan) the  populations  are healthier and have fewer health issues than  in America today. So we  know that there is misinformation, and facts  being taken out of  context.

Of the  concerns over soy, there are a few common ones. First,  is   referring to  raw soybeans, that can contain a form of phytic acid that  can block  certain minerals   absorption. However, that is based on  massive consumption quantities,  and of the raw soybean and only occurs  in those animals that lack the  digestive enzyme phytase. It is only an  issue for people who consume  those foods to get minerals in their diet,  and  in massive quantities. The issue is in developing countries, and  may  have a genetic basis as well because they are lacking the digestive   enzyme (which can be supplemented and therefore alleviate the  concern).   It is not an issue for our products because of  how we  process the ingredients.

The second common concern with soy are due to  some of the components of soy,  particularly the isoflavones genistein  and dadzein which can affect and  inhibit thyroid peroxidase which is  necessary for the production of T3  and T4. Thus  there is some evidence  that it could lead to thryoid enlargement  (Goiter) . Our soy has been  processed to remove the isoflavones, so this  is not an issue.

A third common  concern about soy is  the effect it may have on estrogen  levels in the body. This is again  due to the isoflavones, which we  have had removed. So this is a  non-worry. We should  note that many  menopausal women do supplement with isoflavones, as it  has been shown  to help them experience fewer side effects of menopause.

Lastly,  our Soy is not genetically modified (it is non-GMO).  Many people worry  about genetically modified soy, and if any of the  ingredients got  altered in the breeding process. We use the most  natural form we can  get, that has not been genetically modified.

We use soy because it is a complete protein, easily digested, can build   lean muscle equal to (if not slighly better) than soy, and adequate   consumption of soy in the diet can help the body reduce cholesterol and   c-reactive protein an indicator of inflammation  and heart disease.

Hope this helps.
