Pueraria Mirifica powder can increase breast size, but the effect is minimal. The reason why Pueraria Mirifica powder is considered to have breast enhancement effects is mainly related to the fact that Pueraria Mirifica itself belongs to the legume family and modern pharmacological analysis shows that its main component is flavonoids, in fact, the structure of soy isoflavones is indeed similar to the structure of estrogen in the human body, but not exactly the same. After taking Pueraria Mirifica powder, the flavonoids can be absorbed into the body, but they cannot be converted into estrogen, and can only play a very slight estrogen-like role, so the effect can only be one ten millionth of the real estrogen, therefore, the effect of breast enlargement is very slight. The size of women’s breasts is generally affected by genetic factors and the level of nutrition during the development of adolescence, and the effect of breast enlargement after adulthood is not too obvious.
