Hello! Let me answer it for you, I hope you will be satisfied and it will be helpful to you! Soy isoflavones Isoflavones are one of the flavonoids, mainly found in leguminous plants. Soy isoflavones are formed during the growth of soybeans. Class secondary metabolites. Because it is extracted from plants and has a similar structure to estrogen, it is called phytoestrogens. The estrogenic effect of soy isoflavones affects hormone secretion, metabolic biological activity, protein synthesis, and growth factor activity. It is a natural cancer chemopreventive agent. Prebiotic soy isoflavones are bioactive substances refined from non-GMO soybeans. They are natural nutritional factors with a variety of important physiological activities. They are pure natural phytoestrogens that are easily absorbed by the human body and can quickly replenish nutrients.

Per 100 grams of soybean sample contains 128 mg of isoflavones, the isolated protein produced by traditional methods contains 102 mg of isoflavones, and soy milk contains 9.65 mg, because soy milk contains 93.27% water, which is equivalent to dry matter It also contains more than 100 mg of isoflavones per 100 grams. Tofu contains 27.74 mg of isoflavones, and its dry matter contains more than 200 mg of isoflavones. Isoflavones are weak phytoestrogens, and soybeans are the only effective source of isoflavones for humans. When estrogen has strong physiological activity, isoflavones can act as anti-estrogens and reduce the risk of estrogen-activated cancers such as breast cancer. When women's estrogen levels decrease during menopause, isoflavones can play a substitution role. Avoid menopausal symptoms such as hot flashes. Isoflavones have outstanding anti-cancer properties and can hinder the growth and spread of cancer cells. They only have an effect on cancer cells and have no effect on normal cells. Isoflavones are also effective antioxidants that prevent the formation of oxygen free radicals, which are strong carcinogens. It can be seen that the anti-cancer effects of isoflavones have many ways and pathways. Functions of soy isoflavones

1. Prevention of menopausal syndrome in women

Due to reduced ovarian function in women before and after menopause, the level of estrogen in the body decreases, causing dysfunction in the function of various organs and tissues. Accordingly, a series of diseases appear, and supplementing estrogen can achieve the purpose of preventing and treating such diseases.

Symptoms of menopause in women: hot flashes, sweating, chills, chest tightness, palpitations, shortness of breath, dizziness, blood pressure fluctuations, etc.; emotional instability, irritability, irritability or depression, worry, and insomnia. , memory loss, inability to concentrate, and decreased comprehensive judgment.

2. Prevent and improve osteoporosis

Osteoporosis refers to the reduction of bone tissue, resulting in brittle and brittle bones and easy fractures. Common in postmenopausal women and older men (due to hormonal changes or insufficient calcium and vitamin D). The incidence of osteoporosis in middle-aged and elderly women is much higher than that in men. The main reason is that estrogen levels decrease after ovarian function declines, resulting in a negative balance in bone metabolism and bone mass loss. Isoflavones can bind to estrogen receptors on bone cells to reduce bone loss, while increasing the body's absorption of calcium and increasing bone density.

3. Prevention of breast cancer

Long-term use of estrogen alone can increase the incidence of breast cancer and endometrial cancer by 5 to 7 times. The structure of soy isoflavones is similar to that of estrogen, so it can bind to female receptors on the cell surface and activate other anti-cancer mechanisms, reducing the risk of endometrial cancer and breast cancer in women due to high levels of estrogen.

4. Prevent cancer

Soy products contain 5 known anti-cancer factors, one of which is phytoestrogens (isoflavones), which is a unique anti-cancer effect of soy foods factor. Scientists concluded that genistein's antioxidant properties and anti-hyperplasia properties are primarily responsible for its anti-cancer effects. Soy isoflavones have obvious therapeutic effects on breast cancer, colon cancer, lung cancer, prostate cancer, skin cancer and leukemia. Soy isoflavones can also prevent the occurrence of ovarian cancer, colon cancer, gastric cancer and prostate cancer.

A large number of studies have found that soy isoflavones can transform cancer cells into cells with normal functions. At the same time, they can also inhibit undesirable mass structure and prevent mass proliferation and cancer cell spread.

5. Prevent cardiovascular disease

Heart disease is also a disease related to estrogen. As phytoestrogens, soy isoflavones have the following mechanisms for lowering blood lipids and preventing heart disease: : Estrogen-like effect promotes thyroxine secretion and bile excretion.

It has been well documented that it lowers low-density lipoprotein (LDL) cholesterol without lowering high-density lipoprotein (HDL) cholesterol when lowering cholesterol. As a characteristic of flavonoids, isoflavones have biological antioxidant effects, which is very important. Because the oxidation of low-density lipoprotein (LDL) cholesterol is a key factor in the arteriosclerosis process. Women who received 80 mg of pure genistein per day increased arterial elasticity by approximately 26%.

6. Prevent Alzheimer’s disease

Alzheimer’s disease is currently the most common form of dementia, and women are more likely to suffer from it. In recent years, studies have shown that the human brain is also a target tissue for estrogen. The hippocampal synaptosomes in the brain, which have memory functions, contain estrogen receptors. The medical community has confirmed that estrogen levels are closely related to Alzheimer's disease. Taking it Soy isoflavones and real estrogen are both good for the brain.

7. Beauty and anti-aging effects

The estrogen-like effects of soy isoflavones can make women’s skin smooth, delicate, tender, elastic, and rejuvenated. Women activate the adipose tissue in the breasts by supplementing estrogen, causing free fat to be attracted to the breasts, thereby achieving the effect of breast enlargement.

Research shows that modern women experience early menopause. Long-term supplementation of soy isoflavones can maintain normal levels of estrogen in the body, delay menopause, and delay aging.

8. Improve menstrual discomfort

Menstrual discomfort is generally related to the imbalance of estrogen secretion. Long-term supplementation of soy isoflavones can maintain normal levels of estrogen in the body and achieve the purpose of improving menstrual discomfort. .

9. Improve the quality of sexual life

The estrogen-like effect of soy isoflavones can increase the maturity of women's vaginal epithelial cells and enhance the elasticity of vaginal muscles, thereby improving the quality of sexual life.

10. Lower cholesterol

Cardiovascular disease (CHD) is a multifactorial disease, in which cholesterol (Ch) plays an important role. The results of a large-scale study of 5,000 people conducted in Japan showed that soy isoflavones have the effect of lowering cholesterol and inhibiting thrombosis. A British study on young women showed a dose-effect relationship of isoflavones. More than 45 mg of isoflavones per day for 30 days could reduce total Ch and LDL-Ch levels by 10%, while 23 mg of isoflavones had no effect.

11. Regulate blood lipids to prevent cardiovascular disease

Soy isoflavones can reduce the body's susceptibility to serum LDL oxidation. After serum LDL lipoprotein is oxidized, it activates the phagocytosis of macrophages in the human body and develops into foam cells in the arterial wall, thereby forming atherosclerotic plaques. Soy isoflavones not only have antioxidant effects themselves, but can also induce an increase in antioxidant enzyme activity, increase the antioxidant properties of serum LDL, prevent the formation of atherosclerotic plaques on arterial walls, and prevent atherosclerosis. At the same time, it increases the compliance of arterial blood vessels and dilates blood vessels. Soy isoflavones also inhibit the atherosclerotic process by affecting tyrosine kinase, including foam cells, fatty streaks, hyperplasia, fibrous plaque infiltration, rupture and ulcers, maintaining the smooth flow of cardiac arteries and preventing cardiovascular diseases. occurrence.

Suitable groups for soy isoflavones

1. Suitable for middle-aged and elderly women

According to the understanding of female ovarian function decline, women around 35 years old begin to need Take isoflavones. Take a small dose before the age of 40, a sufficient dose between the ages of 41 and 50, and a large dose after the age of 50. Those with menopausal symptoms must increase the dose, and adjust the dose according to personal feelings and body reactions. (Note: Pregnant and lactating women should not take isoflavones.) 2. Suitable for sick people

·People with cardiovascular disease;

·Alzheimer's disease;

·Prostatic hypertrophy;

·Osteoporosis;

·Women with menopausal disorders.

3. Suitable for sub-healthy people

·People who improve liver function and prevent diabetes;

·Constipation people;

·Beauty Beauty care and anti-aging skin.

4. Soy isoflavones are not suitable for:

(1) Underage girls

(2) Women who have not taken contraceptive measures and are preparing to conceive

(3) Pregnant and lactating women

(4) Patients with breast cancer, breast hyperplasia, and uterine cancer should use it with caution. How to choose soy isoflavones scientifically

1. Choose name-brand or branded products:

Don’t choose particularly cheap products. Many small businesses engage in fraud, product prices are very low, and product quality is difficult to guarantee; do not choose particularly expensive products. Many products pretend to be foreign, Hong Kong and Macao brands, with very high prices, and product quality is not necessarily guaranteed. Because of quality problems, There is no way to claim compensation;

2. Choose products that have been produced and operated for many years:

The long production and operation time proves that the company's products have gone through the market selection of the fittest, and only high-quality products can survive for a long time. Go down. The quality of products that have not been selected by the market over a long period of time is unreliable;

3. Choose products with clear soy isoflavone content on the product label:

Many companies are not clear on the label The content of active ingredients is indicated because the content is low. The active ingredient of soy isoflavones can only be effective if you take 50-100mg every day. Some products are made of soy flour, which has insufficient active ingredients and is not effective;

4. Choose products with anti-counterfeiting labels:< /p>

Due to the best-selling products, there are fakes on the market, and it is easy to buy fakes without anti-counterfeiting measures;

5. Choose products that are non-GMO and extracted from natural raw materials:

It is not recommended that you choose imported or fake imported soy isoflavone products (domestic production with foreign trademarks), because the imported ones are extracted from genetically modified soybeans, and the fake imported ones are products that deceive the people. Some non-standard pharmaceutical companies also produce soy isoflavones. Since they often use hormones, in order to improve the effect of their products, some companies add hormones to their products;

6. Choose products produced by professional companies. Do not choose small health care product companies or OEM products;

7. When choosing the dosage form of isoflavones, be cautious or do not choose soft capsule products.

Why? First, because the raw material of soy isoflavones is powdery and has poor water solubility and fat solubility, it is unscientific to choose a liquid solvent; second, soft capsules are used to protect medicines or health care products that are prone to oxidation and deterioration. Yes, soy isoflavones are very stable and not easily oxidized and deteriorated, so there is no need to package them in soft capsules; thirdly, the packaging cost of soft capsules is higher than that of hard capsules and tablets, so the cost of soft capsules is high. It is not competitive. If soft capsule products are sold very cheaply, it is questionable; fourth, the soy isoflavone soft capsules currently on the market are not transparent capsules. Or pink, or gray, etc. Why is it not transparent (similar to products like fish oil)? It is because if it is transparent, it will expose product defects. Therefore, it is not recommended that you buy soft capsules, and the content of active ingredients in many soft capsule products is questionable. Soy isoflavones are better in hard capsules and tablets. If you have good gastrointestinal function, you can choose capsules and tablets. If you have poor gastrointestinal function, it is best to choose tablet products.

Soy isoflavones are a very commonly used health product and are generally sold in regular pharmacies! I hope the above answer can help you. If you think it is good, please accept it as the answer, thank you! ^_^
