lack of B1 temper

The formula made up of vitamins B1, B6 and B12 is claimed to improve pain and paralysis. Why are they chosen among the many vitamin Bs?

Nutritionist Wan Kan pointed out that vitamin B1 helps the body convert food into energy, and also helps maintain the normal functioning of the nervous system and heart; people who lack B1 are less responsive, irritable, poor memory, weight loss and often feel tired, etc. Nerves, muscle function, and the heart are all affected.

“Vitamin B6 assists the conduction function of the nervous system, produces hemoglobin, and maintains the normal operation of the immune system. It is also important for brain development. Those who are deficient may suffer from anemia, headaches, acne and depression.”

“Vitamin B12 helps make red blood cells,

Maintain cellular and nervous system health,

Deficiency can cause anemia, numbness or tingling in hands and feet,

Severe difficulty with body balance,

Depression, confusion, etc.

The above three B vitamins are all very important for maintaining a healthy nervous system, “but not more is better, the point is to have enough.”

Orthopedic surgeon Lin Jianwei said that there are literatures that vitamin B can help accelerate nerve recovery. Therefore, orthopedic surgeons sometimes prescribe vitamin B for patients with severe nerve compression, such as carpal tunnel syndrome, cervical spine displacement, and nerve rupture requiring surgical repair. B supplements.

“However, if it is just occasional numbness, the effect is doubtful, and vitamin B can be absorbed in daily food, so it is not necessary to use supplements.”

Prescribing the right medicine is the best policy

Wan Kan added that body pain has different causes. It may be due to strain or insufficient muscle mass. Numbness in hands and feet may be caused by insufficient magnesium. In such cases, vitamin B supplementation will not help.

Lin Jianwei also pointed out that the cause of pain must first be found out. Prescribing the right medicine is the best policy. There are many reasons for neck pain and arm pain. It may be muscle tension, incorrect posture, and excessive use of the phone. These have nothing to do with nerves. (Supplementing vitamins B) Must not help.

“The numbness of the hands and feet may be due to carpal tunnel syndrome, herniated disc or degeneration of the lumbar bone compressing the nerves. It needs to be diagnosed by a doctor before an appropriate treatment plan can be arranged.”

Wan Kan reminded that excessive intake of vitamin B will not have additional effects. The dosage of vitamin B supplements sold on the market is generally far more than the body needs. Although vitamin B is water-soluble, the excess will be excreted in the urine, but excessive consumption will cause Increase the load on the kidneys, and side effects such as dizziness and vomiting may also occur.

“Especially people with chronic diseases, such as kidney disease, should seek professional advice before taking vitamin B supplements.”

Vegetarians are vulnerable to B12 deficiency

“Whole grains, such as whole wheat bread, brown rice, red rice, etc. contain vitamins B1 and B6.”

Wan Kan pointed out that in addition, vitamin B1 can be taken from beans, meat, and nuts; vitamin B6 can be taken from protein foods, such as chicken, beef, sheep, pigs, and fish. Meat, fish, milk, clams, oysters, crabs and eggs are food sources of vitamin B12.

As long as the average person eats a balanced diet, it is not difficult to get enough vitamin B. For example, 60 grams (about half a cup) of cereal flakes (muesli) contains 0.5 mg of vitamin B1; 100 grams of pork contains 0.5 mg of vitamin B6, and a banana contains 0.7 mg Vitamin B6; 100 grams of beef has 3 micrograms of vitamin B12.

However, people with poor gastrointestinal function, who have undergone gastric surgery, vegetarians, and the elderly should pay attention to whether they may not be getting enough vitamin B12.

Lin Jianwei explained that vitamin B12 needs to be absorbed by a protein in the stomach (intrinsic factor). If there is a problem with the stomach or the stomach has been removed, the body cannot absorb vitamin B12 if it fails to produce this substance.

In addition, Wan Kan said that vitamin B12 is mainly absorbed from fish, meat, eggs, and milk, so vegetarians are prone to vitamin B12 deficiency.

“It can be found in foods fortified with vitamin B12, such as some cereal flakes, soy milk and bread, and supplements as needed.”
