(1) High secretory period (youth before 25 years old)

(2) Hyposecretion period (30-50 years old, middle age)

(3) Secretory deficiency (middle age and old age over 50 years old)

(4) Secretory termination

There are natural bioactive peptides in the body, mainly including peptide hormones secreted by some important endocrine glands, which are highly efficient bioactive substances secreted by endocrine glands or endocrine cells.

As a messenger in the body, it can transmit information, regulate the metabolic activities of various tissues and cells, and make the body form a highly tight control system, thus affecting the growth, development, reproduction, metabolism and behavior and other life processes.

At different ages, the secretion of various bioactive peptides is also very different. According to the secretion, human life can be generally divided into the following four periods:

(1) High secretory period (youth before 25 years old)

During this period, the endocrine system functions vigorously, the secretion of various bioactive peptides is balanced, the human immune function is strong, and the human body is generally not prone to diseases. After 25 years old, the secretion will decrease by 15% every 10 years.

(2) Hyposecretion period (30-50 years old, middle age)

At about 30 years old, the organs and tissues of human body began to age and atrophy, and their functions declined. The secretion of various bioactive peptides was only 85% of the peak.

At the age of about 45, there is a sharp decline in appearance (such as sharp relaxation and aging of skin) and body physiology (hypogonadism) of both men and women. There are a series of changes in the functions of human nervous system and immune system, and a variety of related sub-health and mild disease symptoms.

(3) Secretory deficiency (middle age and old age over 50 years old)

By the age of 60, the secretion of active peptide was only about 1 / 5 of the peak, and by the age of 80, only 1 / 10 was left. During this period, if the active peptide is seriously insufficient and unbalanced, there may be very prominent aging symptoms, or it may cause various related diseases.

(4) Secretory termination

During this period, due to the decline of cell function, organ failure and loss, no longer secreted active peptide, leading to the end of life.

With the natural aging of human body, the number of active peptides secreted by human body will gradually decrease. However, the rapid pace of modern life, fierce competition for survival, high emotional pressure, environmental pollution, unhealthy diet and other factors cause the human body to be generally in a "sub-health" state, with the overload of various functional organs and the decline of physiological functions.

Exogenous small molecular peptide not only has high nutritional value, but also can regulate metabolism and physiological function of human body. It is very important to maintain normal life activities. Therefore, it is very beneficial for any population to supplement exogenous small molecular peptides.
