About Male Menopausal Symptoms

Testosterone, a male hormone, plays a  crucial role in maintaining male physical and mental functions. However, the  amount of testosterone gradually decreases with age. External factors such as  lifestyle and stress also impact testosterone levels. Decreased testosterone is  closely related to conditions such as sarcopenia, which involves muscle loss  and muscle weakness, and also affects the causes and prevention of various  diseases, including angina, arteriosclerosis, obesity, metabolic syndrome, and  dementia. These conditions associated with decreased testosterone are known as  Late Onset Hypogonadism (LOH) syndrome. Reports indicate that about 10% of  middle-aged men in employment suffer from male menopausal symptoms, with a  notable prevalence starting from the late 40s, making LOH a significant social  and economic concern.

LOH manifests in a variety of symptoms  including general fatigue, decreased libido, lack of motivation, ED, difficulty  concentrating, insomnia, irritability, shoulder stiffness, urination problems,  a sense of heaviness in the head, and fewer morning erections. Additionally,  age-related testosterone decline increases the risk of several health issues  such as depression, sexual dysfunction, cognitive decline, cardiovascular  diseases, increased visceral fat, insulin resistance, decreased HDL  cholesterol, and elevated total cholesterol and LDL cholesterol.

About Agaricus blazei/brasilensis/subrufescens

Agaricus blazei/brasiliensis/subrufescens is a type of  mushroom widely used in the field of complementary and alternative medicine as a health food and supplement. The characteristics and components of Agaricus vary depending on the strain, cultivation conditions, and origin. The quality of Agaricus-containing products also varies significantly among different products.

Brazilian Outdoor-Cultivated Agaricus KA21  Strain (King Agaricus KA21)

King Agaricus KA21 is cultivated outdoors under  the sun using the King Agaricus 21 strain (KA21) in Brazil. Compared to typical indoor-cultivated Agaricus grown in dark conditions, this strain grows larger  and contains more key components such as β-glucan and vitamin D. It also  features over five times higher antioxidant activity.
