Studies have indicated that a daily 25 to 100 mg dose of Krao supplements is safe. However, there are some adverse reactions, which are listed in the next section.

Phytoestrogens can be found in many native plants like P. mirifica and B. superba. These chemical compounds mimic estrogens.

Phyto is the Greek word for “plant.” “Estrogen” is the hormone that regulates important body functions, such as metabolism, reproduction, and sexual function.

Although phytoestrogens are plant-based, they function like animal estrogens.

According to researchers, the safest dose of P. mirifica is 25 to 100 mg per day. If the dose is increased, you may experience reproductive disorders, hot flashes, sleep disorders, and mood swings.

The roots of Pueraria mirifica contain 17 phytoestrogens. These 17 are naturally-occurring compounds that function like estrogens in female humans.

The phytoestrogens have been categorized into chromenes, coumestans, and isoflavonoids. Microestrol is the most common chemical compound found in the plant’s roots.

Microestrol is a chromene and a pharmaceutical agent. According to RCARO, microestrol can increase breast size since it acts like estrogen.

Studies show that intake of Krao supplements can decrease alcohol craving.

A 100 mg daily dose of Krao solution for 4 months can reduce menopausal symptoms, including skin dryness, high cholesterol levels, frustration, sleep disorders, etc.

As women grow older, their bone mass decreases. The plant’s phytoestrogens slows bone deterioration. In rats, ingestion of Pueraria mirifica prevents osteoporosis and rheumatism.
