Genistein is a polyphenolic isoflavone originally found in the Genista tinctoria plant which it was named after. Natural sources of genistein include tofu, fava beans, soybeans, kudzu, and lupin. It is a phytoestrogen that is a naturally occurring chemical constituent with a similar chemical structure to mammalian estrogens.

In humans, genistein has shown beneficial effects for protection against osteoporosis, reduction in the risk of cardiovascular disease, alleviation of postmenopausal symptoms and anticancer properties. It also has anti-inflammatory properties. It is currently being studied in clinical trials as a treatment for prostate cancer. Unfortunately, Genistein is limited in its bioavailability after oral administration due to its poor water solubility.

Chicks40 mg/kg of dietGI healthimproved intestinal morphology, mucosal immune function, tight junction, antioxidant activity, apoptotic process, and growth performance, which were adversely damaged by LPS injection.Z Lv et al., 2020
Hens40-400 mg/kg of dietantioxidantcan alter lipid metabolism in the offspring chicks through epigenetic modification and improve the antioxidative capability as well as growth performance.Z Lv et al., 2019
Hens3-106 mg/hen/dayantitumor, ovarian cancerdemonstrated the preventive effects and mechanisms of genistein in the laying hen model that develops spontaneous ovarian cancer at high incidence rates. Genistein supplementation significantly reduced the ovarian tumor incidence (P = 0.002), as well as the number and size of the tumors (P = 0.0001).K Sahin et al., 2019
Hens40-400 mg/kg of dietbone strength, egg qualitycould improve the egg production and quality, as well as the bone status of LBB hens during the late egg-laying period.Z Lv et al., 2019
Hens40-400 mg/kg of dietliver protection, fatty liver syndromeDietary GEN alleviated metabolic disorder and inflammation in the FLS hens by improving the antioxidant capacity and fatty acid profile.Z Lv et al., 2018
Chicks20-80 mg/kg of dietimmunityCBH response and antibody titers against Newcastle and infectious bronchitis disease viruses were markedly greater in chicks fed on diets supplemented with 20 to 80 mg/kg of genistein. Dietary inclusion of genistein increased lymphocytes and subsequently reduced heterophil to lymphocyte ratio. E Rasouli et al., 2015
