What is vitamin B1?

.

Vitamin B1 (thiamine) is a vitamin water-soluble. It is responsible for the functioning of cells in the body, as well as the production of energy from nutrients. The body only stores trace amounts of thiamine in the liver. It is therefore necessary to take vitamin B1 daily with the dietand.

Properties of thiamine 

.

Vitamin B1 is an essential nutrient that affects numerous processes in the body. How does thiamine work?

• Increases energy production. The primary role of carbohydrates is to provide the body with energy. Vitamin B1 plays a very important role in this process. It helps the body's cells convert carbohydrates into energyand.
.
• Helps fight depression. Vitamin B1 relieves symptoms of depression and improves mood. Furthermore, thiamine deficiency has been linked to poor moodand.
.
• Helps people with diabetes. Research suggests that taking thiamine has a positive effect on blood sugar levels. It doesn't stop there, vitamin B1 lowers high blood pressure and prevents cardiac complications in people with diabetesand.
• Reduces symptoms of sepsis. Tiamine in combination withvitamin C alleviates symptoms of sepsis. It may also reduce the risk of kidney failure, which often follows infectionand.
• Prevents nerve damage. B vitamins, including thiamine, positively influence regeneration of damaged nerves. Its deficiency leads to peripheral neuropathy. Furthermore, combining vitamin B1 with vitamin B12 may alleviate nerve pain in people with diabetesand.
• Improves memory.  Thiamine supplementation may improve memory and concentrationand.

Vitamin B1 requirement

.

Adequate vitamin concentrations are the basis for a healthy body. How much thiamine do we need each dayand?

.

*Nutrition standards for the Polish population

.

The requirement for vitamin B1 increases during pregnancy and breastfeeding. When you are expecting a baby, you should take 1.4 mg of thiamine per day. Conversely, during breastfeeding, the requirement for vitamin B1 is even higher at 1.5 mgand.

Sources of thiamine

.

Thiamine should be supplied to the body with the diet. Healthy meals are the key to a healthy body. In which products can we find vitamin B1and?

Vitamin B1 deficiency

.

Thiamine deficiency in developed countries is a rare occurrence. However, specific groups of people may be particularly vulnerable to vitamin B1 deficiency in the body.

What affects thiamine deficiencyand?

• AIDS/HIV.

  .

• Alcohol addiction alcohol dependence.

• AIDS/HIV.

• Inappropriate diet. 

• Taking certain medications.

• Long-term parenteral nutrition.

• Prolonged diarrhoea.

• Prolonged diarrhoea.

Symptoms

.

Symptoms of thiamine deficiency can be easily overlooked. They are most often vague and mimic signs of other conditions. Which ones should raise our concern?

.

Fatigue

.

Thiamine is essential in the production of energy, which is why its deficiency can manifest as fatigue. The first signs can appear as early as a few weeks after a deficiency. Although fatigue can be a symptom of many conditions, numerous studies have linked it specifically to vitamin B1 deficiencyand.

Greater mood

.

Vitamin B1 deficiency leads to sudden changes in mood. Its lack in the body can manifest as irritability or feelings of irritability. Interestingly, this symptom is also indicative of thiamine deficiency in infantsand.

Tingling in arms and legs

.

Tingling in the limbs can be a symptom of a deficiency of vitamin B1. Thiamine is essential for the proper functioning of the nerves. Therefore, a lack of it leads to paresthesia - tingling in the arms and legs. In the long term, this can result in damage to the peripheral nervesand.

Blurred vision

.

Thiamine deficiency also affects vision. It manifests as swelling of the optic nerve, leading to blurred vision. Supplementation of vitamin B1 in such cases significantly improves vision. Furthermore, preliminary animal studies suggest that thiamine intake may prevent the visual damage caused by alcoholand.

Omega acids, especially omega-3 also affect eye health. I invite you to check out these articles!

What are the other symptoms of thiamine deficiencyand?

• Problems with logical thinking.

• Loss of short-term memory.

• Loss of short-term memory.

• Diffidence.

Vitamin B1 deficiency disease - beri-beri

.

Beri-beri is a disease caused by vitamin B1 deficiency. Its most common cause is a lack of a balanced diet. There are two types of beri-beri diseaseand:

• Wet. Affects the heart and circulatory system. In extreme cases, it can lead to heart failure.

• Dryness. Damages nerves and reduces muscle strength. If left untreated in the long term, it can even result in paralysis.

• Sickness.

Beri-beri disease is diagnosed using blood and urine tests. Doctors also perform neurological examinations for this purpose. Treatment of beri-beri is most often through supplementation monitored by a specialist.

Treatment of beri-beri is usually by supplementation monitored by a specialist.

Excess vitamin B1

.

The body excretes excess thiamine with urine. Consumption of vitamin B1 in doses as high as 50 mg per day has not caused side effects.and 

This is why a maximum daily dose of thiamine has not been established. This is most likely due to the fact that the absorption of vitamin B1 at doses above 5 mg, is significantly reduced by our body .

.

Tiamine supplementation

.

Want to replace a healthy diet with supplements? Forget it! It is balanced meals that influence our health. Sometimes, however, it is necessary to "top up" the vitamin B1 requirement. The exceptions to this are extreme deficiencies. Then supplements are advisable.

.

How long to take?

.

The length of supplementation depends on the doctor's recommendations. In cases of severe deficiency, very high doses may be taken - either orally or by injection. This can reduce the deficiency symptoms associated with the heart within days or even hours. In contrast, reversing the effects of thiamine deficiency related to the nervous system or brain, can take up to three to six monthsand.

Contraindications

.

Vitamin B1, like all other vitamins for the general public, is safe. However, if you have had allergic reactions involving it, ask your doctor's opinion before starting supplementation. Furthermore, people with any medical conditions or who are allergic to certain ingredients in supplements should also seek advice from a specialist.

Morning or evening?

.

Thiamine, like pantothenic acid, folate or vitamin B3, is a water-soluble vitamin. This is why it is a good idea to take it in the morning, on an empty stomach. The best time to do this is about half an hour before your first meal. However, if you do not have this option, take vitamin B1 at any time of the day.

Vitamin B1 in pregnancy

.

Vitamin B1 influences the health of pregnancy. It supports the development of the baby and also helps to convert carbohydrates into energy. It affects the function of the nervous system and the heart. Furthermore, thiamine deficiency negatively affects the development of cognitive functions in the yet unborn child. The recommended dose of thiamine for pregnant women is 1.4 mg per dayand.

Thiamine and breastfeeding

.

The breastfeeding period, like pregnancy, is governed by its own rules. The need for thiamine is higher then (1.5 mg per day), and a deficiency will translate into a lack of vitamin B1 in the infant's body. The result, will be gastrointestinal symptoms, heart failure or lactic acidosisand.

Vitamin B1 and alcohol

.

Alcoholism leads to impaired absorption of thiamine from the gut. Therefore, people who abuse alcoholic beverages are at risk of vitamin B1 deficiency. The result can be serious problems with brain function, cognitive function, memory, intellect or personalityand.

Furthermore, long-term alcohol consumption leads to Korsakov syndrome. It manifests as amnesia and cognitive impairment.

Interactions of thiamine with drugs

.

It has not been established with which drugs vitamin B1 interacts. However, some agents can affect its concentration. This is primarily furosemide, a diuretic drug that lowers blood pressure. Some chemotherapy drugs can also adversely affect thiamine concentrationsand.
