What are vitamins? How to absorb?

The best time to take vitamins.

It is more effective when taken after meals; Because the digestive activity of the gastrointestinal tract tends to be active after meals, it is conducive to the absorption of vitamins by the body. In particular, fat-soluble vitamins A, D, and E are suitable for taking after meals because they are absorbed with the help of the fats that are ingested after a meal. The higher the fat content of the diet, the better it is for the absorption of fat-soluble vitamins.

If you eat a fairly light diet, you can add milk to help with absorption.

Vitamin C is also one of the vitamins that should be taken after a meal. Although vitamin C is a water-soluble vitamin, it can still cause diarrhea when taken in large amounts, so it is suitable to take it immediately after a meal and when the gastrointestinal burden is low.

If you are suffering from constipation, you can choose to take it before meals to achieve better results.

Water-soluble vitamins should be taken in 3 times a day: fat-soluble vitamins are not excreted in the urine, so you can take the required amount in one day at a time. However, if it can be divided into 3 doses after meals, it is more effective in the body.

On the other hand, water-soluble B vitamins and vitamin C are easily excreted in the urine, so it is best to divide them into 3 times a day.

Vitamins that are ingested into the body, each with the most effective amount in the body. Exceeding this amount is either excreted from the body through urine, or it is a burden on the body. In particular, water-soluble vitamins are excreted only through the excretory organs if they are taken in excess.

Therefore, the best thing to do is to divide the required amount of the day into 3 times. When taken after three meals, the effect will be more significant.

Pay attention to the timing of other medications: for example, vitamin B1 is afraid of alkaline substances, and when you take vitamin B1 preparations, it should not be taken with alkaline-containing gastrointestinal medicines, otherwise the effect of vitamin B1 will be greatly reduced.

It is a trace element, divided into two kinds of lipid capacity and water capacity, the general lipid capacity is not easy to lack, the excretion is less, and the water volume is easy to be excreted with urine, so it needs to be replenished regularly.

It's a thing of the human body.

Vitamins can be absorbed through food.

1. Vitamin A: animal liver, eggs, milk. The liver of animals is rich in vitamin A and has the highest content, especially the livers of sheep, chickens and pigs.

2. Carotene: The content of darker fruits and vegetables is higher, such as: broccoli, carrots, spinach, amaranth, lettuce, rape, liquid snow peas, mangoes, oranges, pipa, etc.

3. Vitamin B12: meat, animal offal, fish and poultry, shellfish, eggs, etc.

4. Vitamin C: Fresh jujube has the reputation of "the king of vitamin C", and most of the vitamin C is found in fresh fruits and vegetables, such as peppers, chrysanthemum, bitter gourd, beans, spinach, potatoes, leeks, etc.

After the water-soluble vitamins are absorbed from the intestines, they circulate to the tissues needed by the body, and most of the excess is excreted in the urine and stored very little in the body. Most of the fat-soluble vitamins are absorbed by bile salts, which travel through the lymphatic system to various organs in the body. Large amounts of fat-soluble vitamins can be stored in the body.

Vitamins A and D are mainly stored in the liver, vitamin E is mainly stored in adipose tissue, and vitamin K is stored to a lesser extent. <

Vitamins A and D are mainly stored in the liver, vitamin E is mainly stored in adipose tissue, and vitamin K is stored to a lesser extent. Water-soluble vitamins are easily soluble in water but not easily soluble in non-polar organic solvents, and are stored very little in the body after absorption, and the excess is mostly excreted in the urine; Fat-soluble vitamins are easily soluble in non-polar organic solvents, but not easily soluble in water, and can be absorbed by the body with fat and accumulated in the body, and the excretion rate is not high.

Vitamin D3 is the most beneficial for the human body to absorb, and eating these foods regularly can supplement vitamin D

After the vitamin is absorbed from the intestines, it circulates to the tissues that the body needs, and the excess is excreted by the urinary system. Therefore, vitamins do not need to be eaten too much, and do not eat them on an empty stomach, as they will be excreted before they are absorbed.

Vitamins are a class of organic compounds that are necessary for the maintenance of good health. This kind of substance is neither the raw material that constitutes the body's tissues nor the ** of energy in the body, but a class of regulatory substances that play an important role in the metabolism of substances. These substances are not synthesized in the body or are not synthesized in sufficient quantities, so they are required in small quantities but must always be supplied by food.

Vitamins are found in food in the form of provitaminostats;

Vitamins are not components of the body's tissues and cells, and it does not produce energy, its role is mainly to participate in the regulation of the body's metabolism;

Most vitamins cannot be synthesized by the body or are not synthesized in sufficient quantities to meet the needs of the body, and must be obtained frequently through food;

The human body's need for vitamins is very small, and the daily requirement is often calculated in milligrams or micrograms, but once the deficiency occurs, it will trigger the corresponding vitamin deficiency and cause damage to human health.

Vitamins are essential organic compounds in the body's metabolism. The human body is like an extremely complex chemical factory, constantly undergoing various biochemical reactions. The reaction is closely related to the catalytic action of enzymes.

For an enzyme to be active, it must have a coenzyme involved. Many vitamins are known to be coenzymes of enzymes or components of coenzymes. Therefore, vitamins are important substances for maintaining and regulating the normal metabolism of the body.

Yes, there are also water and inorganic salts that can also be directly absorbed by the body without digestion.

No, in fact the role of the stomach is mainly mechanical digestion and chemical digestion of gastric acid, with the effect of absorbing water and a small amount of alcohol.

The main digestion and absorption are carried out in the small intestine.

In addition, the large intestine can also absorb small amounts of water, vitamins, and minerals.

Yes, water-melting, and the human body is water, most of it is water, so it is directly absorbed, of course, the food cannot be directly absorbed, vitamins B and C are water-melting, vitamins A and E are fat-melting, but fat-soluble can not be taken in large quantities, otherwise it will be poisoned.
