• Присъствието на фолати и B12 означава, че не трябва да се използват други добавки, съдържащи витамини от група B, без консултация с лекар.

• Въпреки че опаковката е икономична, голямото количество таблетки изисква систематичност и подходящо съхранение.

.

It is found in soya products, dairy products or semolina, among others. It is assumed that 60 mg of tryptophan contributes to the production of 1 mg of vitamin B3 equivalent in the body."

Vitamin B3 deficiency

.

Vitamin B3 deficiency is most often caused by a lack of a balanced diet. While it is rare in developed countries, it is common in developing countriesand. 

Other causes of vitamin B3 deficiency include:

.

• excessive alcohol consumption,
.
• disorders of the gastrointestinal tract,
.
• long-term treatment with isoniazid (an anti-tuberculosis agent),
.
• genetic conditionsand.
.

.

"Vitamin B3 deficiency is not usually observed in the population. It may affect alcoholics, people with intestinal disease or Hartnup's disease."

Agata Grzelaczyk, nutritionist

.

.

Symptoms

.

Although vitamin B3 deficiency is rare, our body will quickly let us know when it is lacking. What should concern usand?

Symptoms of vitamin B3 deficiency:

• fatigue,
.
• vomiting,
.
• diarrhea,
.
• headaches,
.
• memory problems,
.
• apathy,
.

Vitamin B3 deficiency disease - pelagra

.

Long-term vitamin B3 deficiency can result in pelagra. This is a disease that attacks cells that function throughout the body. It manifests with the above symptoms and, in a later stage, also a thick, dark and scaly skin rash. Pelagra also leads to brain and nerve damage, as well as oral ulcersand.

.

How to cure?

The treatment of vitamin B3 deficiency is not complicated and usually involves taking supplements. In most cases, your doctor will choose products that contain no less than 20 mg of this compound. The exception is people with advanced vitamin B3 deficiency. Then independent treatment of specific damage to the body (if it has occurred) may be necessary.

.

Vitamin B3 overdose

.

It is impossible to overdose vitamin B3 by eating products that are rich in itand. The only way to end up with an excess of vitamin B3 is to irresponsibly exceed the dosage prescribed by your doctor or to take more supplements than recommended by the manufacturer.

.

"Excess vitamin B3 supplied with the diet is excreted in the urine. In contrast, excess vitamin B3 from dietary supplements can cause what is known as the 'flash effect'.

"This is a common phenomenon.

This manifests itself as reddening of the skin and a tingling sensation. What's more, high doses of vitamin B3 can damage the liver, and increase the risk of developing type 2 diabetes by as much as 34%."

Agata Grzelaczyk, nutritionist

.

.

Symptoms

.

Just as our body does not like to be deficient in something, it is also bothered by an excess of certain substances. This is precisely the case with vitamin B3.

.

Symptoms excess vitamin B3 in the bodyand:

• nausea,
.
• vomiting,
.
• severe reddening of the skin,
• somnolence,
.
• diarrhoea,
.
• itchy skin,
.

Caution! 

.

If you experience the above symptoms, stop taking vitamin B3 immediately and see your doctor.

Vitamin B3 - supplementation

.

Most of us are sufficient with vitamin B3 provided with our diet. More often than not, supplementation is a last resort reserved for people with malabsorption disorders, alcoholics or those who suffer from genetically limited absorption of vitamin B3. In such cases, see a doctor who will recommend healthy and safe supplementationand.

Why is it on prescription?

.

Vitamin B3 has been linked to liver damage and strokes, so doctors only prescribe it in selected cases. Most commonly, a prescription for vitamin B3 will be given to people who cannot take statins and whose cholesterol is significantly elevatedand.

How long can supplements be taken?

.

More often than not, we are not talking about supplementation, but about treatment. Vitamin B3 in the form of a medicine should be taken for as long as your doctor prescribes and not a day longer. When it comes to supplements, on the other hand, follow the manufacturer's recommendations and make sure not to exceed the daily recommended doseand.

.

Contraindications

.

Every doctor will interview you before prescribing vitamin B3 to make sure it is safe for you. Vitamin B3 cannot be combined with selected medications. It is also not recommended for people who have had problems with the liver, kidneys or stomach ulcersand.

Vitamin B3 in pregnancy

.

Vitamin B3 is important for the health of pregnancy. Research suggests that it may prevent birth defects of the spine, heart or kidneys in the baby. The requirement for vitamin B3 in pregnancy is 18 mgand.

Vitamin B3 and breastfeeding

.

Women who are breastfeeding should also make sure they have adequate vitamin B3. Mother's milk is the only source of valuable vitamins and minerals for the newborn. Therefore, ladies who are breastfeeding should take 17 mg of vitamin B3 dailyand.

.

Note!

.

Both in pregnancy and during breastfeeding you should not supplement vitamin B3. The increased need should be met through a balanced diet. An exception to this situation is otherwise recommended by your doctorand.

.

Vitamin B3 and alcohol

.

Alcohol can interact with vitamin B3. Consumption of alcoholic beverages during supplementation or treatment with vitamin B3, may result in an increased risk of liver damage. Furthermore, this action increases the possible side effects of taking niacin, such as itching or redness of the skinand.
