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.

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.
