● What is Soy Isoflavones ?
Soy isoflavones (SI) are natural active ingredients extracted from soybean (Glycine max) seeds, mainly concentrated in germ and bean skin. Its core components include genistein, daidzein and glycitein, of which glycosides account for 97%-98% and aglycones only account for 2%-3%.
Modern extraction technology has achieved high-purity mass production:
Microbial fermentation method: the mainstream process, using non-GMO soybeans as raw materials, fermenting and hydrolyzing glycosides through strains (such as Aspergillus) to improve the activity of aglycones, the purity can reach 60%-98%, and the yield is 35% higher than the traditional method;
Supercritical CO₂extraction: retain antioxidant components under low temperature conditions, avoid organic solvent residues, and meet pharmaceutical grade standards;
Enzymatic hydrolysis-assisted process: using β-glucosidase to convert glycosides into active aglycones, the bioavailability is increased by 50%.
As the world’s largest soybean producing area (with an output of 41.3 billion jin in 2024), China relies on GAP planting bases such as Henan and Heilongjiang to ensure raw material supply and sustainable production.
● What Are The Benefits Of Soy Isoflavones ?
1. Bidirectional Regulation Of Estrogen
Competitive binding to estrogen receptors (ER-β) to relieve menopausal symptoms: daily supplementation of 80 mg can reduce the frequency of hot flashes by 50%, improve insomnia and mood swings. At the same time, it inhibits excessive activation of estrogen and reduces the risk of breast cancer – the incidence of breast cancer in East Asia is only 1/4 of that in Europe and the United States, which is directly related to the soybean diet tradition.
2. Bone And Cardiovascular Protection
Anti-osteoporosis: Soy Isoflavones can activate osteoblasts, and postmenopausal women can increase bone density by 5% and reduce the risk of fracture by 30% by consuming 80 mg daily;
Lipid-lowering and heart-protecting: Soy Isoflavones can regulate cholesterol metabolism, reduce LDL (bad cholesterol) levels, and reduce the formation of atherosclerotic plaques.
3. Anti-Oxidation And Anti-Tumor Synergy
Soy Isoflavones can inhibit tyrosinase activity, reduce DNA oxidative damage, and delay skin photoaging;
Soy Isoflavones can promote the conversion of anti-cancer product 2-hydroxyestrone, and inhibit the proliferation of prostate cancer and leukemia cells.
4. Anti-Inflammatory And Metabolic Regulation
Reduce the expression of inflammatory factor TNF-α and relieve arthritis symptoms; assist in diabetes management by enhancing insulin sensitivity
● What Are The Applications Of Soy Isoflavones?
1. Medicine And Health Products
Menopause management: compound preparations (such as Relizen®) relieve hot flashes and night sweats, with an annual demand growth rate of 12% in the European and American markets;
Adjuvant treatment of chronic diseases: compound preparations with andrographolide are used in Phase II clinical trials of diabetic retinopathy, with an effective rate of 85%.
2. Functional Foods
Dietary supplements: capsules/tablets (daily recommended dose 55-120mg), mainly anti-aging;
Food fortification: added to soy milk, energy bars, yuba (56.4mg/100g), and dried tofu (28.5mg/100g) to become natural high-content foods.
3. Cosmetics And Personal Care
Anti-aging products: add 0.5%-2% of Soy Isoflavones to essence to inhibit collagen degradation and reduce wrinkle depth by 40%;
Sunscreen repair: synergize with zinc oxide to increase SPF value and repair Langerhans cells damaged by ultraviolet rays.
4. Animal Husbandry And Environmental Protection
Feed additives: Improve poultry immunity, reduce piglet diarrhea rate by 20%, and increase carp weight by 155.1% after adding 4% to feed;
Biological materials: Convert bean dregs into degradable packaging to reduce resource waste.
