During the change of seasons, when the daily temperature difference increases, signs of aging are felt more significantly throughout the body. At this time, you should think of ‘collagen’. Collagen is the main ingredient that makes up 90% of the skin dermis, 75% of cartilage, and 80% of ligaments and tendons. Starting in the mid-20s, it decreases by 1% every year, and by the time you reach your mid-40s, it drops to half of that in your 20s. After menopause, it drops by 30% within 5 years, so continuous management is necessary.
◇Decreased collagen, causing sagging skin and urinary incontinence
Collagen, known to be good for the skin, makes up not only the skin but also blood vessels, joints, gums, and bladder. It is a major component that accounts for one-third of body protein. Therefore, if there is a lack of collagen, abnormalities may occur throughout the body, such as sagging skin, high blood pressure, joint pain, gum inflammation, and urinary incontinence.
First of all, collagen accounts for 90% of the skin dermis. Continuous exposure to strong ultraviolet rays, high daily temperature range, and dry environments leads to collagen deficiency. Soon, skin elasticity decreases and the aging process accelerates. Ultimately, red flags arise for overall skin health, such as wrinkles and dryness.
Collagen also maintains the elasticity of blood vessels. When blood vessel elasticity decreases, blood vessels become hard and thick. Because it cannot absorb blood pressure, blood pressure rises, which can lead to high blood pressure. Conversely, if collagen is well supplemented, the risk of cardiovascular disease caused by decreased blood vessel elasticity is reduced. When 30 adults were fed collagen for 6 months, the amount of ‘bad cholesterol’, LDL (low density lipoprotein), decreased compared to ‘good cholesterol’, HDL (high density lipoprotein), and the risk of arteriosclerosis, which causes myocardial infarction and stroke, was reduced. There are also research results.
Degenerative arthritis caused by aging is particularly closely related to collagen. Collagen, which makes up 75% of cartilage excluding water, decreases with age. According to a research paper published in the academic journal ‘Agro Food Industry Hi Tech’, when 100 women in their 40s to 70s with knee osteoarthritis took collagen peptides, joint pain decreased and physical activity ability improved. Additionally, 18% of dentin, the main component of teeth, and 60% of gum tissue are collagen. If there is a lack of collagen, the gums become weak, causing gaps between teeth, and it is easy for bacteria to multiply. According to an overseas paper published in 2016, it was confirmed that the risk of cardiovascular diseases such as heart attack and stroke is twice as high if you have gum disease. In another overseas study that investigated 53 patients with gum disease, the density of gum collagen decreased almost two-fold compared to the control group.
Collagen also makes up more than 80% of the bladder muscle and sphincter. When collagen in the bladder decreases or clumps to one side due to aging, bladder elasticity decreases and the ability to store urine and control urination decreases. This leads to urinary incontinence. A domestic study examining 44 patients with urinary incontinence also found that collagen was significantly lacking compared to normal people.
◇Choose collagen with a high absorption rate in the body. It is better to take it with biotin.
Collagen synthesis rapidly decreases after the age of 40. This is because as aging progresses, the number and activity of fibroblasts that produce collagen in the body decrease. As the amount of body composition decreases, it inevitably becomes vulnerable to external stimulation.
When replenishing collagen lost due to aging, it is best to choose low-molecular-weight collagen peptides in the form of tripeptides, which have a high absorption rate. Low-molecular-weight collagen peptides, which have the same structure as human cells, are absorbed into the skin, blood vessels, and cartilage within 24 hours of ingestion. It also stimulates fibroblasts to activate the production of collagen in the body. In fact, the results of an animal experiment in which low-molecular-weight collagen peptides were consumed for two months showed that fibroblasts increased by about 10% and the cross-sectional diameter of collagen in the dermis became much thicker.
It is better to take together ingredients that help collagen synthesis. There are also animal test results showing that collagen synthesis was more than twice as good in mice administered biotin. When choosing a collagen product on the market, you must carefully check the following: ▲ Collagen with a tripeptide structure ▲ Health functional food recognized for its functionality by the Ministry of Food and Drug Safety ▲ Whether it contains biotin ▲ Human application test results, etc.
