Soy Isoflavones are natural compounds that are found in soybeans and other legumes. They are known for their ability to act like estrogen in the body, which is why some people use them to alleviate menopause symptoms.
Soy Isoflavones have also been studied for their potential benefits for heart health, bone health, and brain function. You can get Soy Isoflavones in your diet by eating foods like soy milk, tofu, and edamame, or by taking supplements.
A 2019 randomized controlled trial found that a combination of Soy Isoflavones and probiotics was effective for reducing hot flashes and other menopause symptoms in postmenopausal women. Other studies have been less conclusive; a 2016 systematic review of 21 randomized controlled trials found that Soy Isoflavones may have some benefits for reducing hot flashes, but the evidence was not strong.
Postmenopausal women may find that this type of phytoestrogen supplement carries particular benefits for them, including helping to improve heart health by reducing inflammation and improving blood vessel function. Postmenopausal women may also experience changes in cognitive function, including memory and overall brain health. Soy Isoflavones may have potential benefits for cognitive function in older women, however the evidence to support this remains limited at best.
Soy Isoflavones are generally considered safe for most people, but some women may experience side effects. The most commonly reported side effects of Soy Isoflavones include digestive issues such as bloating, gas, and constipation. Some women may also experience allergic reactions to Soy Isoflavones, which can cause symptoms like itching, hives, and swelling.
