1. With age, collagen loss leads to dry eyes and fatigue. Poor cornea transparency, hard elastic fibers, turbid lens, and eye diseases such as cataracts.

2. Teeth contain peptides, which can bind calcium to bone cells without loss. With age, the loss of peptides in the teeth leads to the loss of calcium, which leads to dental disease, easy to tooth decay and periodontal disease, loose teeth, pain, susceptibility, weak bite force, etc.

3.  With age, peptide loss, blood vessel wall elasticity deteriorates, affecting the stability of blood pressure, blood viscosity, easy to cause fatty liver, hyperlipidemia, cerebral thrombosis, and memory decline, dizziness, forgetfulness, insomnia.

4.  If lost of peptides lost seriously, then some severe symptom will happen such as stomach acid, bloating, hiccups, stomach cramps, labor pains, flatulence, etc., the absorption capacity of the epithelial cells of the small intestine decreases, the functioning capacity decreases, and occasional gastroenteritis.

5.  The loss of peptides can lead to a decrease in bone density, formation of cavities, and loss of calcium, causing bone and joint pain, bone spurs, inflexible legs and feet, osteoporosis, easy fracture, slow bone healing, and decreased bone toughness.

6.  Peptide loss can lead to memory diminish, inattention, insomnia, dreaminess, anxiety, depression, restlessness, menopausal syndrome, poor response ability, etc.

7.  Peptides affect the thickness, elasticity and suppleness of hair. With age, the loss of peptides can cause dry hair, breakage, hair loss, baldness, split ends, gray hair, increased dandruff, etc.

8.  Severe loss of collagen peptides can lead to cervical spondylosis, insufficient blood supply to the brain, back pain, shoulder numbness, compression of the nervous system, and decreased muscle tone.

9.  The lymphatic channels in the lymphatic system are composed of peptides, which are responsible for the transport of lymphatic fluid. As the age increases, the loss of collagen peptides and slow lymphatic circulation will lead to a decline in immunity and susceptibility to diseases.

10.   Peptides can balance the secretion of hormones. The loss of peptides can cause endocrine disorders, leading to amenorrhea, low menstrual flow, menstrual disorders, early menopause, stunted growth, breast hyperplasia, susceptibility to breast cancer, etc.
