Efficacy of oryzanol and vitamin B 12
Oryzanol is a kind of nutrient element widely existing in cereals. Oryzanol is not a single chemical substance, but is composed of various forms of ferulic acid esters. Its main chemical structure is similar to cholesterol, which belongs to oily substances, but its physiological function is completely different from cholesterol because of the different side chain structure.
The main function of oryzanol is to nourish and regulate autonomic nerves. Oryzanol can nourish autonomic nerves, and has a certain conditioning and improvement effect on gastrointestinal discomfort and insomnia caused by neurosis and autonomic nerve disorder, as well as female menopause and premenstrual syndrome.
In addition, because the structure of oryzanol is similar to that of cholesterol, and it is mainly absorbed in the intestine, some studies have found that taking oryzanol in large doses can competitively inhibit cholesterol absorption and reduce blood lipids; In addition, oryzanol also has certain physiological functions in antioxidation and antiplatelet aggregation, but these are not the main pharmacological effects of oryzanol, nor can it be used to replace conventional drugs related to lowering blood lipid and antiplatelet.
Vitamin B 12, also called cobalamin, is a member of B vitamins and an important coenzyme in our body. Although the required amount is not large, it has important physiological functions. If the daily diet is balanced, the human body usually does not lack vitamin B 12, but we should know that the absorption of vitamin B 12 by the human body can only be completed through an endogenous factor in the intestine. If the intestinal health is damaged, this endogenous factor is not secreted enough, even if vitamin B 12 is ingested, it is difficult to be absorbed, resulting in the problem of vitamin B 12 deficiency.
What if the body lacks vitamin B 12? On the one hand, vitamin B 12 is an important coenzyme for the formation of red blood cells. Therefore, the lack of vitamin B 12 may lead to the problem of pernicious anemia. In addition, vitamin B 12 also has the function of assisting folic acid and enhancing the utilization rate of folic acid. For the nervous system, vitamin B 12 also has a certain nutritional function, which can participate in the formation of a lipoprotein in nerve tissue and plays an important role in human body.
Applicable people and precautions of oryzanol and vitamin B 12
At present, the main application of oryzanol is to supplement nutrition and regulate autonomic nerves. Some friends eat oryzanol for insomnia, which may be because this insomnia problem has a lot to do with autonomic nerve disorder. Therefore, by supplementing oryzanol, they can better improve their sleep quality. Some women have various vasomotor symptoms, such as hot flashes, night sweats, irritability and anxiety. Because the estrogen level in the body decreases during menopause, they can also consider taking oryzanol to adjust and improve menopausal symptoms. Some friends, because of emotional anxiety and tension, affect their autonomic nerves, which further affects the gastrointestinal tract, leading to frequent stomach pains, diarrhea and other problems. You can also consider supplementing oryzanol for adjustment and improvement. No need to take medicine to supplement oryzanol. Eating more whole grains is a good way to supplement oryzanol in daily life.
Personally, I don't agree with the efficacy of oryzanol in lowering blood lipid and reducing the risk of cardiovascular disease. If you want to achieve the efficacy of oryzanol, you generally need to take a large dose of oryzanol. In order to reduce blood fat, long-term overdose of oryzanol may lead to the risk of some adverse reactions, such as hair loss and gastrointestinal discomfort. Don't think that oryzanol is definitely safer than conventional lipid-lowering drugs and antiplatelet drugs, let alone taking oryzanol.
Vitamin B 12 is also an important coenzyme nutrient. Without the human body, it will cause such and such problems. In daily life, vitamin B 12 mainly exists in animal food. Therefore, in the diet structure, pay attention to the collocation of vegetarians, and vegetarians should pay more attention to the intake of milk and beans, which is an important aspect to ensure the balance of vitamin B 12 in the body.
For friends suffering from chronic gastrointestinal diseases for a long time, the health of gastrointestinal tract directly affects the absorption of vitamin B 12. Therefore, if the body is deficient, you can take supplements to supplement vitamin B 12 according to specific problems. In addition, for friends who have long-term drinking habits, long-term intake of alcohol may affect the intestinal absorption of vitamin B 12. Long-term use of metformin may also affect the absorption of vitamin B 12. It is generally suggested that vitamin B 12 can be supplemented at the same time. Older people, the body's absorption ability is weak. If the problem of vitamin B 12 deficiency does exist through inspection, you can also consider supplementing more.
Excess vitamin B 12 will be excreted from urine in the prototype form, but it should be noted that the absorption of vitamin B 12 is closely related to endogenous factors in the intestine. Therefore, if you want to supplement vitamin B 12, you must first do a good job in the healthy conditioning of the intestines. Although vitamin B 12 is safe, you should also pay attention to proper and excessive supplementation.
