Estro-Soy

Pregnancy and breast-feeding: Soy protein is LIKELY SAFE in pregnancy and during breast-feeding when consumed in amounts normally found in food. Higher doses during pregnancy might harm development of the baby. Not enough is known about the safety of higher doses during breast-feeding. Stay on the safe side and avoid larger doses. Cystic fibrosis: Soymilk can interfere with the way children with cystic fibrosis process protein. Don?t give these children soy products. Breast cancer: The effects of soy in people with breast cancer are unclear. Some research finds that soy might ?feed? certain breast cancers because it can act like estrogen. Other studies have found that soy seems to protect against breast cancer. The difference in effects might have something to do with the amount taken. Because there isn?t enough reliable information about the effects of soy in women with breast cancer, a history of breast cancer, or a family history of breast cancer, it?s best to avoid using soy until more is known. Endometrial cancer: Long-term use of concentrated soy isoflavone tablets might increase the occurrence of precancerous changes in the tissue lining the uterus. Don?t take concentrated soy isoflavone supplements if you have endometrial cancer. Kidney disease: There is some concern that soy products might increase the risk of kidney stones because they contain large amounts of a group of chemicals called oxalates. Oxalates are the main ingredient in kidney stones. Another concern is that people with serious kidney disease aren?t able to process some of the chemicals in soy. This could lead to dangerously high levels of these chemicals. If you have kidney disease or a history of kidney stones, avoid taking large amounts of soy.

Side-Effects:

Consuming soy foods such as soy protein is LIKELY SAFE. Taking soy dietary supplements also seems to be safe for most people when used short-term (up to six months). Soy can cause some mild side effects such as constipation, bloating, and nausea. It can also cause allergic reactions involving rash and itching in some people. Long-term use of high doses of soy dietary supplements is POSSIBLY UNSAFE. There is concern that taking high doses might cause abnormal tissue growth in the uterus.

Adverse Drug Reactions:

Antibiotic drugs interact with SOY: Antibiotics are used to reduce harmful bacteria in the body. Antibiotics can also reduce friendly bacteria in the intestines. Friendly bacteria in the intestines seem to help increase the effectiveness of soy. By reducing the number of bacteria in intestines antibiotics might decrease the effectiveness of soy. But it is too soon to know if this interaction is a big concern. Estrogens interact with SOY: Large amounts of soy might have some of the same effects as estrogen. But soy isn't as strong as estrogen pills. Taking soy along with estrogen pills might decrease the effects of estrogen pills. Some estrogen pills include conjugated equine estrogens (Premarin), ethinyl estradiol, estradiol, and others. Tamoxifen (Nolvadex) interacts with SOY: Some types of cancer are affected by hormones in the body. Estrogen-sensitive cancers are cancers that are affected by estrogen levels in the body. Tamoxifen (Nolvadex) is used to help treat and prevent these types of cancer. Soy seems to also affect estrogen levels in the body. By affecting estrogen in the body, soy might decrease the effectiveness of tamoxifen (Nolvadex). Do not take soy if you are taking tamoxifen (Nolvadex). Warfarin (Coumadin) interacts with SOY: Warfarin (Coumadin) is used to slow blood clotting. Soy has been reported to decrease the effectiveness of warfarin (Coumadin). Decreasing the effectiveness of warfarin (Coumadin) might increase the risk of clotting. It is unclear why this interaction might occur. Be sure to have your blood checked regularly. The dose of your warfarin (Coumadin) might need to be changed.
