What are the side effects of taking collagen? What are the effects and functions of collagen?

Since collagen is very important to human health, especially for maintaining skin, reducing facial wrinkles, and beautifying the skin, it is deeply loved by women. Eating collagen has become a very daily health method, but collagen can also have side effects. So what are the main side effects of eating collagen?

1. Cause obesity

Collagen itself has no side effects on the human body, but if you take collagen in large quantities for a long time, or eat collagen products containing additives such as sweeteners, it can easily lead to excess calories in the body and a significant increase in weight, making the body obese.

2. Cause allergic reactions

Although few people will have an allergic reaction to protein, it is easy to cause an allergic reaction when the body's immune system is dysfunctional, especially causing a large number of red maculopapules and rashes on the skin, accompanied by itching and discomfort. In severe cases, it can induce the occurrence of diseases such as exfoliative dermatitis or anaphylactic shock.

3. Causes skin to lose elasticity

Originally, collagen has the function of beautifying and improving skin condition. However, if collagen products are taken improperly, it may damage the originally healthy skin, especially stimulating the more sensitive epidermal cells, causing the skin in many parts to lose elasticity and become rough.

4. Increased uric acid levels

Since collagen is generally extracted from fresh fish, poultry and egg products, it is an acidic food. When taken in large quantities at one time, it will lead to an increase in uric acid levels in the blood and lactic acid will also increase, thus affecting health.

5. Impact on fetal development

Pregnant women are not suitable for taking collagen, because the collagen products sold on the market often contain ingredients such as amino acids that the fetus cannot absorb and utilize, which will affect the normal growth and development of the fetus. Therefore, it is necessary to avoid taking it during pregnancy. If you need to supplement protein, you can eat more high-protein foods.
