Many friends will buy some vitamin E supplements. “To take it for a long time, in order to supplement enough vitamin E, but in fact, what is the benefit of vitamin E in the body? Do you really need to take supplements for a long time? There are still many lack of understanding and misunderstanding.

What is the effect of vitamin E?
Like our common vitamin C, vitamin E is also a nutrient that humans cannot synthesize. It needs to supplement the body’s vitamin E through external intake. So what is the effect of vitamin E? It mainly includes the following aspects:

  1. Improve and delay the progression of atherosclerosis and protect cardiovascular health. The occurrence and development of arteriosclerosis is closely related to the deposition and oxidation process of lipids in the blood vessel wall. Vitamin E is a kind of vitamin with strong anti-oxidation effect. Therefore, the body properly and moderately consumes vitamin E, which is helpful for cardiovascular and cerebrovascular diseases. Treatment and prevention have certain auxiliary effects.
  2. Good for reproductive system health. This nutritional role for the reproductive system is both male and female. If men lack vitamin E, it will lead to atrophy and degeneration of testicular epithelial cells, affecting sperm motility, and vitamin E supplementation can stimulate male sex hormone secretion and improve energy vitality. It is a good nutrition for the adjuvant treatment of male infertility. Supplementation; for women, vitamin E can increase estrogen concentration and increase fertility.

Do vitamin E need to be supplemented with supplements?
Vitamin E has so many important effects, how much should it be added every day? The recommended daily dose given in China’s nutritional diet guidelines is 14 mg, and the logo converted into active units is only about 22 IU. The so-called recommended daily dose is that you can take so much vitamin E every day. For normal healthy friends, it is enough to supplement the body.

Many foods are rich in vitamin E, asparagus in vegetables, broccoli, etc., avocado in fruits, papaya, etc., all kinds of nuts, eggs, vegetable oils and animal oils are rich in vitamin E, so in daily life In life, maintaining a good diet and eating habits is all that is needed to supplement the body’s normal vitamin E.

Modern people’s life is getting better and better. Many friends don’t need too much nutrition, but they eat too much. Therefore, if there is no clear vitamin E deficiency, it is not recommended to take vitamin E supplements to supplement the body’s vitamins. Let’s take a look at the vitamin E content of our common medicines and health care products. It is usually 100mg of capsules, and many vitamin E health supplements on the market, the amount of 400IU is labeled. If these values ​​are converted into mg, it is equivalent to 267mg. One capsule a day, the vitamin E added to the body is far away. Exceeding the daily recommended daily dose, don’t think that vitamin E is a nutrient. It doesn’t matter if you eat more and eat less. Long-term overdose of vitamin E may cause various health risks.

Some friends think that vitamin E is anti-aging, good for health, and even vitamin E supplemented in large doses for decades, but what is the real situation? Excessive vitamin E supplementation may cause adverse reactions such as nausea, vomiting, dizziness, headache, etc. Some friends may have blurred vision, chapped skin, cheilitis, angular cheilitis, diarrhea, breast enlargement, fatigue, irregular menstruation, heart Problems such as increased risk of vascular disease are really worth the loss.

Seeing this, some friends may be a bit confused, not to say that vitamin E anti-aging, protect mucous membranes and cardiovascular health, but also help women’s reproductive health? How are these side effects reversed? In fact, no matter how good the nutrition, if it is ingested in moderation, it will play a positive role in health care. If you eat too much in the long-term and eat too much, it will often be counterproductive. Let’s take vitamin E. The study found that if 200-400 mg of vitamin E is added every day, long-term supplementation will increase the risk of cardiovascular and cerebrovascular diseases. That is to say, appropriate supplements can be added to supplement the vitamin E to protect the cardiovascular system. On the contrary, it will increase the risk of cardiovascular disease. There are still many examples of this, and they are not listed one by one.
