1. Vitamin C

Vitamin C is a water-soluble vitamin that is essential to the existence of human life and the maintenance of health, and is found in fresh vegetables and fruits, and is one of the most common nutritional supplements on the market today. Vitamin C has relatively strong antioxidant properties, which can be converted to hemi-dehydroascorbic acid and dehydroascorbic acid through the process of supplying electrons one by one, thus scavenging free radicals such as negative superoxide ions and hydroxyl radicals from our body. Vitamin C also promotes the absorption of iron, participates in hydroxylation reactions, detoxifies the body, and improves the immune system.

2. Vitamin E

Vitamin E, also known as tocopherol, is a general term for tocopherols and trienyltocopherols, which are fat-soluble vitamins essential to our bodies. Vitamin E is a very important antioxidant in the non-enzymatic antioxidant system, which plays a protective role in the stability of biological membranes and facilitates the permeability of the human body, and may prevent the polyunsaturated fatty acids, cytoskeleton and sulfhydryl groups of other proteins in the biofilm and lipoproteins from being attacked by free radicals and oxidizing agents, so as to maintain the completion of cell membranes; sufficient vitamin E also has a certain anti-atherosclerotic effect, affects human reproduction, and has the ability to protect the human body from the effects of oxidation. It also has anti-atherosclerotic properties, affects human reproduction and development, protects the nerves and muscles, regulates the immune system, and protects against kidney damage due to oxidative reactions and lipid peroxidation.

However, as the saying goes, "There is no such thing as good or bad, but too much is a disaster", these ingredients that are effective for our bodies may not only fail to have a positive effect, but may also lead to the occurrence of certain diseases if they are consumed in excess. When taking these supplements, the amount of food consumed should be strictly controlled.

For some relatively young female friends, because of their own body's estrogen is relatively adequate, as long as to ensure a reasonable, healthy diet, in fact, there is no need to supplement these antioxidant supplements; to maintain their own health, delay their own aging, as well as to extend their own life, but the most important thing is still need to rely on the daily correct diet, can not be used to supplements to The most important thing is to eat right and not to use supplements to replace your diet, which may make your body worse.

But for some relatively special stage of the population, such as: maternity, patients, or people with smoking and alcoholism, as well as high-risk groups of people, etc., in taking nutrient supplements, it is best to be in the professional dietitian or health management personnel under the guidance of taking, do not blindly unauthorized consumption.

However, whether it is vitamin C, vitamin E or or grape seed capsules, the absorption rate in our body is actually related to the intake of a certain amount, when the intake increases, the absorption rate will have a significant decline.

So that vitamin C, appropriate intake is indeed will be on our health still have some help, but if a long time to take capsules of health products, it is likely to affect their own absorption as well as efficacy.

In addition, foreign studies have also found that both vitamin C or or vitamin E, if carried out for a long time in excessive use, it is likely to cause some damage to our body.

Therefore, to summarize, if it is only as a health supplement, we do not recommend you to take it for a long period of time. If you are experiencing symptoms of vitamin deficiency, we recommend that you take additional supplements after testing. As a general population, it is best to supplement with food. Fruits such as kiwis, oranges, mangosteen, grapes, etc., which are rich in antioxidant vitamins, can be eaten more often.

There are many kinds of antioxidant supplements for sale on the market, such as vitamin C, vitamin E, grape seed capsules, etc. Many women take these substances for a long time because of their advertised ability to slow down the aging process and improve beauty. However, what kind of effect will long-term consumption of these supplements have on the body?

Grape seed extract contains a strong and effective natural antioxidant that cannot be synthesized in the human body, called proanthocyanidin oligomers, belonging to a kind of bioflavonoids, accounting for about 80% to 85% of the content of the active ingredient in grape seed.

If you have a good suggestion for this issue, you are welcome to leave a comment below!

I am Wang Guizhen, welcome to pay attention to [Wang Guizhen dietitian] headline number, together to talk about health, so that we eat healthy, eat at ease!

Hello, vitamin C, vitamin E and grape seed capsule common characteristic is with antioxidant effect. In recent years, there is a continuous study found that the human body aging, tumors, etc. are related to oxidation, so the business began to play antioxidant card, and constantly launch a variety of antioxidant products. Among them, vitamin C, vitamin E, grape seed capsules and coenzyme Q10, lycopene, astaxanthin and so on in an endless stream, not only health care products, there are a variety of antioxidant cosmetics.

The human body in contact with nature, cell oxidation process will produce free radicals, free radicals will cause damage to cells, causing aging, disease and even tumors. Vitamin C, vitamin E, grape seed, these substances with antioxidant properties, can synthesize part of the free radicals, play a protective role in the human body.

But whether it is vitamin C, vitamin E or grape seed capsules, the absorption rate in the human body is related to the intake, when the intake increases, the absorption rate decreased significantly. So vitamin C vitamins, appropriate intake will indeed have a certain help to health, but if you take a long time to take capsules of health products, may affect the absorption as well as efficacy.

In addition, foreign studies have also found that both vitamin C and vitamin E, if used in excess for a long period of time, may also cause some damage to the body, making the incidence of cancer significantly higher.

I think a nutritionist who is a long term multivitamin supplement herself. She said that when she first started taking them she seemed to feel like a person was a little more refreshed, but after taking them for a long time, once she forgot to take them, she noticed that her nails were noticeably brittle. This shows that taking extra supplements for a long period of time can also affect how much our bodies need, and may be even worse for our bodies once we stop.

So all in all, it is not recommended to take it for a long period of time if it is only used as a health supplement. If the body does experience uncomfortable symptoms caused by vitamin deficiencies, it is recommended that additional supplementation with pharmaceutical preparations is indeed needed after testing. As a general population, it is best to supplement through food. For example, kiwifruit, oranges, mangosteen, grapes and other fruits, are rich in a variety of antioxidant vitamins, can be appropriate to eat more.

Tell my personal experience, I have been taking these for some time, grapeseed capsules, vitamin E several formulated, and collagen powder. Probably eat 5 months, each month to eat these costs about 1000 yuan, the skin becomes white and tender. Of course also use their skin care products timeline 1320 yuan set. That year, I do not know what reason, my uterus was found to have fibroids, and then later I stopped these, after a few months to review the uterus surprisingly nothing happened. I don't know if it was a misdiagnosis by the doctor or if it was from taking those.

Vitamins are essential physiological active substances, vitamin C has antioxidant, promote collagen formation, prevention of scurvy, promote iron absorption to prevent anemia and many other physiological functions, and vitamin E also has to remove free radicals, cardiovascular protection, regulate ovarian function, promote sperm and egg binding and many other effects. However, today I would like to emphasize with you: any good thing, for the human body to supplement, must be in moderation, more than enough will be counterproductive.

The downside of overdosing on vitamin C

Vitamin C is a water-soluble vitamin, in the human body can not be synthesized by itself, generally need exogenous supplementation, in daily life, there are many vitamin C-rich vegetables and fruits, such as lemons, cherries, kiwifruit, oranges, dates and other fruits, broccoli, kale, green peppers, and other vegetables, are rich in Vitamin C ingredients, can be eaten in moderation in daily life, easy to replenish the Vitamin C, it is important to note that, because of the Vitamin C's antioxidant effect, its own is also very easy to be lost and oxidized, therefore, be sure to eat fresh fruits and vegetables, will be more effective in supplementing vitamin C.

How much vitamin C does the human body need in a day? According to the Dietary Nutritional Guidelines for Chinese Residents, a daily intake of 100mg of vitamin C for adults and 130mg of vitamin C for the elderly is sufficient, how much is this amount? Take kiwifruit as an example, a medium-sized kiwifruit contains about 62mg of vitamin C. Therefore, eating one kiwifruit a day, together with other food sources of vitamin C, is usually enough for the body's vitamin C needs.

For vitamin C oversupplementation, in general, because vitamin C is water-soluble vitamin C, it is easier to be excreted with urine, but in fact, the half-life of vitamin C in the body (i.e., the time required to halve the concentration in the blood) is 16 days, and it takes a long time for it to be excreted after oversupplementation. According to the literature, under normal circumstances, a daily intake of vitamin C of no more than 1,000mg is usually not too harmful to the human body, but if excessive intake of vitamin C for a long period of time, it can cause the emergence of a variety of physical problems such as urinary stones, kidney stones, cardiovascular and cerebrovascular problems, and so on.

Therefore, it is recommended that all ladies who loveVitamin C can nourish the face and anti-aging, but please note that supplementation should be in moderation!。

The downside of excessive Vitamin E supplementation

Compared to Vitamin C, oversupplementation of Vitamin E can be even more harmful! Why, because Vitamin E is a fat-soluble vitamin, a vitamin that is more difficult to remove from the body as opposed to water-soluble vitamins. How much Vitamin E does the human body need per day? According to the Dietary and Nutritional Guidelines, adults only need to consume 14mg of vitamin E per day to meet the body's needs, while the guidelines recommend a maximum daily intake of 30mg.

Usually, the vitamin E content labeled inside many supplements is marked with UI, what is the relationship between UI and mg? Different vitamins, the conversion relationship is different, 1UI of vitamin E, equivalent to 0.688mg, that is, 30mg of the maximum supplement is equivalent to 43UI of vitamin E, and our health care products, many of them are labeled as containing 300 or even 400UI of vitamin E, this amount if true, is much more than the human body's daily needs. Excessive supplementation of vitamin E is very harmful to the human body, research has found that daily consumption of vitamin E more than 400 mg, headache, dizziness, nausea, blurred vision and menorrhagia or amenorrhea and other situations occur. In clinical and real life, there are also many women found to eat Vitamin E or grape seed health products, the emergence of menstrual irregularities. The root cause of this is due to excessive supplementation of Vitamin E.

In fact, daily life, egg yolks, vegetable oils, dried fruits, deep-sea fish are rich in vitamin E, and many vegetables and fruits, such as tomatoes, carrots, onions, mango, avocado, etc., also contain a moderate amount of vitamin E, moderate attention to replenishment, it is entirely possible to supplement the body's needs.

Finally, to summarize, for vitamin C, because of its water-soluble easy to lose characteristics, such as daily dietary intake is insufficient, can be supplemented in moderation, and for vitamin E, do not recommend taking health supplements for supplementation, if you have to supplement, please read the labeled amount, be sure to pay attention to do not overdose.

This is a very good question! We know that Vitamin C is an antioxidant active ingredient, Vitamin E has anti-aging properties, and grape seeds contain polyphenol antioxidant active ingredients.

However, everything can not be excessive, excessive, food is still so, let alone medicine call? Health food can't be overdone.

Below, I'm going to join the gang and talk about Vitamin C, Vitamin E, and Grape Seeds, and how they can affect women when taken long term. Just for your information.

Long-term use of vitamin C, effects on women

Vitamin C is very characteristic, it is as a component of food when, such as vegetables, fruits rich in vitamin C, because the content is very low (generally in less than 10%), so, everyone is very fond of it, both clinicians, or ordinary people, often hanging on the lips of the sentence is: "Eat more vegetables and fruits rich in vitamin C! "

However, when it comes to vitamin C health food (referring to legal health food with a blue hat), the state began to control, the first control stick is the requirement that all vitamin C health food, in the packaging logo, instructions in theYou can't write about therapeutic functions, only auxiliary effects.

Why? Because the purity of vitamin C in health foods can even be as high as 50% or more now, and taking it for a long period of time without clear indications may bring about adverse reactions.

Finally, when it comes to the drug vitamin C, the requirements are even stricter, with the instructions for use of vitamin C tablets for pharmaceutical use stating that they can only be used toPreventing scurvy, it can also be used as an adjunctive treatment for various acute and chronic infectious diseases and purpura.

And the instructions are contained in the manual:

1. Long-term use of 2-3 grams per day can cause scurvy after stopping the drug, so it is advisable to gradually reduce the amount of stopping the drug;

2. Long-term application of large amounts of vitamin C can cause urate, cysteinate or oxalate stones;

3. Overdose (more than 1g per day) can cause diarrhea, red and shiny skin, headache, frequent urination (more than 600mg per day), nausea and vomiting, stomach cramps.

Long-term use of vitamin E, effects on women

Vitamin E, like vitamin C, is also marketed in products from vitamin E in foods, to vitamin E in health foods, and finally to vitamin E in pharmaceuticals.

Here's a special reminder to the guys about a phenomenon that is health food, theThere is usually very little written about adverse reactions, contraindications, and precautions, but mostly about the good things about it.

However, this is not the case with medicines, which will contain adverse reactions in detail, such as those contained in the Vitamin E softgels drug instruction manual:Prolonged overdose can cause nausea, vomiting, dizziness, headache, blurred vision, chapped skin, lipitis, xerostomia, diarrhea, breast enlargement, and fatigue.

And it is contained in the notes:This product is an adjunctive therapeutic agent, you should consult your physician before using this product for the first time, and you should go to the hospital for regular checkups during treatment.

Long-term use of grape seed, effects on women

Because at present our country grape seed, there is no quasi-nominal drugs on the market, only grape seed health food, in summary, because health food generally only talk about the good aspects, will not be like drugs, detailed contained adverse reactions, contraindications, as well as precautions, so I temporarily can not evaluate the adverse effects of long-term use of grape seed on women.

However, you can refer to the drug inserts for Vitamin C tablets and Vitamin E softgels.It is not recommended to take grape seed for a long period of time, or if you need to take it for a long period of time, follow your doctor's instructions.

To summarize: Whether it is vitamin C, vitamin E, or grape seed, if you need to take it for a long time, you must follow your doctor's instructions; otherwise, it can have a negative impact on women's health.

Do you agree with me?

Daily update on health hotspots, medical pain points; if what I say, is exactly what you think, then please like, retweet, follow Zhu Xiaojun said health!

Special note: All recommended medications in the comments section should be tried with caution and never purchased with a call!

Vitamin C, vitamin E is vitamins, grape seed is this fired up antioxidants, if your wallet bulging not bad money, usually pay attention to the amount taken, there is no overdose, then long-term eating in addition to spending money, generally do not have any effect. But expect to rely on eating these things to prevent and cure diseases, eternal youth that is also impossible.

Vitamin C is something that can actually be satisfied by eating more fruits in general. And fruit contains not only vitamin C, but also other vitamins and trace elements, dietary fiber. It's much better than just a little pill. Moreover, many people who take vitamin C, eat health care products vitamin C, a bottle of more than a hundred, buy fruit can eat for a long time.

Vitamin E is also a vitamin, can also antioxidant, but some women eat it will appear endocrine disruption, so not everyone is suitable for this thing, and long-term overdose, it may also lead to menstrual disorders and so on.

As for grape seed, it's also an antioxidant, but it's simply not realistic to think that you can stay young by taking some grape seed. To be honest, health supplements, you can use them to count on the icing on the cake, that is, you are already pretty good and then not too bad off, so take some supplements to help yourself maintain that goodness, but don't count on it to snowball.

If your body is already a mess, counting on health supplements to improve it is still unreliable. If you are sick, eat well, sleep well, have a regular routine, have balanced nutrition, exercise, and a good mood, it may be better than a bunch of health supplements you spend money on.

People are not malnourished with a normal diet, and more nutrients are not always better

These nutrients, I don't know what the side effects of taking them are, I've taken them myself and now I'm off all of them!

However, the nutrients of this kind, whether synthetic or extracted from natural foods, are definitely affected during processing

Do you want your body to accept natural foods!!!? Or artificial food?

Vitamins are also known as vitamins, and their English name isvitamin, they can not be synthesized in the body or the amount synthesized can not meet the needs of the body, there must be an external supply. They are trace elements in the body, and together with other components, they form enzymes, or catalysts, which play a catalytic role in the synthesis and decomposition of proteins, fats, carbohydrates, and other major components of the body, that is, they are involved in regulation.

This is like a factory, both the front-line workers involved in the production, but also administrative and logistical personnel involved in the regulation and protection, do a good job in the production process of the front-line workers in the need for life, thought, etc., and this enzyme is like administrative and logistical personnel, an enterprise's employees or the original staff, but if an entrepreneur outside of the human resources management personnel level of high and low level of production of the enterprise also plays a A great role in the daily production, cost savings and so on play a great role.

This is like the role of enzymes, essential, but not too much, if the leadership of the Ministry of Human Resources is too much, one will cause the organization to be bloated, one will cause the collusion, the decree does not work, but also will cause the problem of profit distribution of the first-line personnel and administrative and logistical personnel, resulting in the weakening of the work of the first-line personnel, vitamins in the human body is the same, belong to the micro-minor, essential, but not too much, too many It is also a sin.

There are quite a few types of vitamins, just like the questioner mentioned vitamin C, E, etc. is one of them, it is because of their role in the human body, but instead, they are used by some businessmen to use for a large number of promotional purposes, and thus taken for a long period of time, but if your diet structure is reasonable, the digestive system is fine, these vitamins are enough to supply the body's needs, and there is no need to add additional ones, or else it will lead to an additional burden on the body, or even Dysfunction, the body also needs to find ways to streamline the military, to remove these excess from the digestive tract, from the skin, from the respiratory system, from the urinary system, theCauses diarrhea, eczema, hives, itchy skin, asthmaAnd so on symptoms occur. So.Supplementation is needed if you are partial, or if your food supply is severely inadequate, or if your stomach and intestines are not digesting and absorbing properly.。

The main components of grape seed are linoleic acid and anthocyanins, the body's fat metabolism to play a balancing role, anthocyanins can play an anti-aging role, people with poor spleen and stomach to eat less, eat more is also a burden on the human body, which can lead to abdominal pain and diarrhea and other symptoms.

So it would seem that the first thing to do is to rationalize our habits, our diet, and

To give an adequate source of vitamins, as well as to guarantee at all times that our digestive system functions well.

It can obtain and absorb sufficient nutrients from the food provided, including various vitamins and various proteins, fats, carbohydrates, etc. This is consistent with Chinese medicine, which states that the spleen is the foundation of the human body. This is consistent with the Chinese medicine saying that "the spleen is the foundation of the later generations". Digestive system is good, as long as not partiality, a variety of nutrients can be guaranteed. Of course, if the digestive system function is weak, you can add the body needs a variety of nutrients, including vitamins, but theThe solution to the underlying problem is the spleen and stomach, a well-functioning digestive system, a proper dietary structure, and no partiality.This doesn't just apply to men, but to women as well.

Many people say that supplements don't work when you take them. Then please ask? What effect do you want? See the effect that is medicine. All health products will write a sentence above: this product can not replace drugs. Health care products have no therapeutic effect on diseases. Health care products health care products is to play a health care role in the goods. It can only play a role in health care. For example, vitamins, in fact, the daily dietary intake of many can meet. Collagen, a lot of pork rinds and chicken claws contain. Then why do we still eat these? Because the lifestyle of modern people is much different than before. Most of the day is either at work or on the way to work. Meals are often cashed up to eat, not to mention eating fruit. Takeaways are basically not very nutritious. In this case we need to take proper nutritional supplements, also known as nutraceuticals. It makes up for the lack of our food intake and is quick and easy to eat straight away without cooking. And our body absorbs these vitamins is also just to achieve a balanced and healthy state of the body. For some focus on diet, diet balanced people, there is really no need to go to additional supplements.
