What Are Isoflavones?

Isoflavones are substances derived from plant-based foods. They are a form of phytoestrogen, which means that in the human body they have estrogen-like qualities. Though their effects are less powerful than the estrogen hormone, they still have protective functions. This is why isoflavones can help to balance hormones and support healthy menopause

Dietary sources of isoflavones include soy products and legume seeds[1]. Soybeans have the highest concentration. You can also obtain isoflavones from a daily dietary supplement. Once eaten, isoflavones are absorbed in the gastrointestinal tract.

Isoflavones Benefits and Uses

Isoflavones have a number of health benefits, particularly for women. This is because they can improve the symptoms of menopause such as hot flashes, breast tenderness, night sweats, irritability, and mood swings[2]. The effectiveness of isoflavones is thought to be due to their similarity to the female hormone estrogen. Isoflavones may also support healthy bones and joints[3] and healthy blood sugar levels[4]. The recommended daily intake of isoflavones is 40 to 50 mg per day.

Isoflavones Side Effects

Isoflavones are generally considered safe to use, though soy isoflavones and other phytoestrogens may cause the following unwanted effects:

  • Bloating
  • Cramping
  • Upset stomach
  • Nausea
  • Skin rash

Though it is considered safe to intake the small amounts of isoflavones found in food while pregnant or breastfeeding, a supplement is not recommended at these times. You should not take soy isoflavones if you suffer from cystic fibrosis, as this may affect protein metabolism.

You should avoid isoflavones if you are currently suffering from, or have a medical history of breast cancer or endometrial cancer. Some types of these cancer are sensitive to estrogen and even estrogen like-compounds like phytoestrogens.

There is some concern that soy isoflavones may increase the risk of kidney stones in some people[5]. Soy isoflavones may also worsen hypothyroidism (underactive thyroid)[6].

Fermented soy products, such as soy sauce and tofu, contain small amounts of tyramine, an amino acid that plays a role in regulating blood pressure. Some antidepressants, like monamine oxidase inhibitors, or MAOIs, decrease the breakdown of tyramine; therefore, consuming more than 6 mg of tyramine while taking this type of antidepressant may result in elevated blood pressure[7].

Isoflavones Overdose

There are currently no reports of overdose from isoflavones. If you think you have taken too much of this supplement and you are experiencing unpleasant effects, stop taking it straight away and seek medical advice.
