Nowadays, with the improvement of people's awareness of health care, more and more middle-aged and elderly people have joined the army of health care products, not hesitating to spend half of their life savings, and even turn against their children because of this. Under the hype of merchants, there are more and more patterns of health care products, and the effect is becoming more and more miraculous, and some patients even take health care products as medicine, and stop taking drugs without authorization and causing a big disaster.
The question is, are these health products really as godly as the merchants say? You might as well take a look at the following 4 popular health products, I hope that after reading it, you can gain something.
Melatonin
Melatonin is closely related to sleep regulation in the human body. It is an amine hormone secreted by the pineal gland gland in the human brain, and its secretion will increase at night under the normal circadian rhythm, helping the body to adjust the biological clock, thus having the effect of improving sleep. In the application of health food, for some special groups, such as night workers who need to sleep during the day or people who need jet lag, melatonin can help them adjust their sleep cycle and make it easier to adapt to abnormal work and rest times.
Melatonin is indeed an essential hormone for the human body, but its health benefits are grossly exaggerated. For the general public, especially those with severe sleep disorders, it does not fundamentally solve sleep problems, relying on melatonin alone, and cannot treat various complex causes of sleep disorders, such as psychological stress, disease factors, etc. Moreover, if melatonin is taken for a long time or in excess, it will also interfere with the body's biological clock, leading to sleep disorders, and further affecting the work and life status during the day.
Deep-sea fish oil
Fish oil is rich in the polyunsaturated fatty acid DHA, which may play a role in regulating blood lipids, and for some patients with hypertriglyceridemia, appropriate supplementation may help control blood lipid levels. In addition, DHA also plays an important role in brain development, and has a certain role in promoting the brain and vision development of fetuses, infants and young children.
Despite these effects, additional fish oil supplementation is not necessary for the average healthy person. Because the fish and other foods in the human daily diet can already provide enough nutrients such as DHA. Moreover, deep-sea fish oil in the form of health products itself lacks effective pharmaceutical ingredients, and its effect in regulating blood lipids is far less than that of professional drugs prescribed by doctors. For teenagers, if they take a large amount of fish oil for a long time, it may also make the body dependent on it and affect their normal physiological regulation mechanism.
Liver protection tablets
Most of the active ingredients of common liver protection tablets on the market are silymarin. The protective mechanism of silymarin on the liver is complex, which not only has a repair effect on damaged hepatocytes, but also has a protective effect on undamaged hepatocytes to prevent the occurrence of liver disease.
Anti-liver injury: stabilizes the hepatocyte membrane, prevents toxins from further invading hepatocytes, and reduces the continued damage of hepatocytes. It stabilizes the hepatocyte membrane and enhances the resistance of hepatocytes to various hepatotoxic substances, which plays a role in preventing the occurrence of liver disease.
Antioxidant: remove free radicals produced by liver damage, reduce the secondary damage of oxidative stress to damaged liver cells, promote the repair and regeneration process of liver cells, restore the normal function of the liver, remove free radicals that may cause liver cell damage in advance, and prevent liver cells from being damaged due to oxidative stress.
Even so, liver protection tablets are not the all-powerful liver "protectors" as advertised. For alcoholics, Liver Protection does not prevent alcohol from entering the bloodstream because it is not involved in the catabolic process of alcohol. Moreover, the oral absorption effect of silymarin is not ideal, for ordinary people, if they take liver protection tablets for a long time, not only can not achieve the expected liver protection effect, but may increase the burden on the liver due to the metabolic problems of the drug in the body, causing further damage to the liver.
Bovine colostrum
Bovine colostrum is the milk of dairy cows within 7 days after giving birth, and it is rich in nutrients, such as immunoglobulins, etc., which can theoretically promote cell growth and development, and have certain antioxidant and anti-aging effects. In some specific cases, for some people with low immunity, rational use may help improve the body's immunity.
However, there are also many limitations to the use of bovine colostrum. First of all, it is not suitable for infants and young children, because it belongs to physiological abnormalities, high acidity, infants and young children's gastrointestinal development is not yet sound, and it may cause diarrhea after eating, resulting in decreased immunity. Secondly, bovine colostrum may cause rejection reactions in the body, such as allergies. In addition, in order to pursue the so-called "high quality", some manufacturers add various nutrients without permission, which changes the original nutritional structure of bovine colostrum, and consumers may cause foodborne diseases due to excessive intake of certain nutrients.
