Niacin

An acid C6H5NO2 of the vitamin B complex found commonly in animals and plants and used particularly against pellagra. [1]

Summary

Niacin is a kind of vitamin B3 made in the body from tryptophan. It’s discovered in lots of foods consisting of meat, fish, milk, eggs, green veggies, and cereals.

Niacin is required for the proper function of fats and sugars in the body and to maintain healthy cells. At high doses, niacin may help individuals with heart problem because of its impacts on blood clot. It might also improve levels of fats called triglycerides in the blood.

Prescription forms of niacin are approved by the United States FDA for abnormal cholesterol levels and for avoiding vitamin B3 deficiency and associated conditions such as pellagra. Individuals utilize niacin supplements for metabolic syndrome, heart problem, cataracts, high blood pressure, and many other conditions, however there is no good clinical evidence to support most of these other uses.

Do not confuse niacin with NADH, niacinamide, inositol nicotinate, IP-6, or tryptophan. These are not the same. [2]

History of pellagra

Pellagra was unidentified to the doctors of the ancient world and the Middle Ages. It was initially explained by the physician Gaspar Casal in Spain in 1735, soon after the maize was introduced into Europe. The name of the illness was developed in 1771 by an Italian physician Francesco Frapolli.

Due to the terrific boost in using maize in northern part of Italy, pellagra became so widespread that a special hospital (known as Legano) was integrated in 1784, specifically for pellagra patients. Reports on the occurrence of pellagra appeared quickly afterwards in France (1829 ), Romania (1858) and Egypt (1874 ).

After 1900 pellagra ended up being a considerable health issue in the United States as well, particularly in the South. It closely followed the introduction of a brand-new grain processing approach that removed the majority of the vitamins from processed grain. There was a particular shift from the use of coarsely ground corn meal in regional, water-driven mills to finely bolted meal by large milling companies.

The break outs of pellagra were so common and serious that a bulk of physicians considered the cause to be a transmittable representative. The true nature of illness was determined when the Federal Government of the United States sent a doctor from New york city, Joseph Goldberger, to study the illness.

The discovery of niacin

Nicotinic acid was synthesized in 1867 by oxidation of nicotine and widely used in photography. It was long thought that it has nothing to do with food or health issues, up until German researchers demonstrated that nicotinic acid occurs in yeast and in rice polishing. There it was isolated by the Polish-American.

biochemist Casimir Funk in 1912, while he was looking for a remedy for another disease known as beriberi (dietary condition triggered by a shortage of thiamine).

Because nicotinic acid had no result on beriberi, he deserted his deal with that substance. However although he was wrong, he showed that this nicotinic acid most likely had some nutritional value. It was delegated the Austrian-American doctor Joseph Goldeberger to find the connection in between nicotinic acid and deficiency illness it can cause.

In 1915, Goldberger performed a series of experiments on 11 healthy volunteer detainees in a Mississippi prison and discovered that he could cause pellagra by modifying their diet plans. He concluded that the disease was brought on by the lack of some factor that was doing not have in corn, however that could be discovered in meat and milk. He named it the P-P (for pellagra-preventative) aspect.

The chemical structure of that element was consequently discovered in 1937 by the American biochemist Conrad Arnold Elvehjem. He caused a black tongue in pets by feeding them the Goldberger diet, and after that cured the disease by supplementing their diet with nicotinic acid. He likewise separated the P-P element from active liver extracts, showing that this aspect is in fact nicotinic acid (subsequently called niacin for nicotinic acid vitamin).

After this discovery, grain products (wheat, maize) were enhanced with nicotinic acid or nicotinamide. Still, a large scale social reform was required to make sure correct execution of such dietary modifications. The majority of sporadic cases in the developed nations are now seen in alcoholics, although in rare instances other clients can establish the illness as well (i.e. malabsorption or iatrogenic scenarios). [3]

Production

Biosynthesis

In addition to taking in niacin from diet plan, niacin can be manufactured from the important amino acid tryptophan, a five-step process with the penultimate compound being quinolinic acid (see figure). Some bacteria and plants use aspartic acid in a pathway that also goes to quinolinic acid. For human beings, the effectiveness of conversion is estimated as requiring 60 mg of tryptophan to make 1 mg of niacin. Riboflavin, vitamin B6 and iron are required for the process. Pellagra is a consequence of a corn-dominant diet plan due to the fact that the niacin in corn is inadequately bioavailable and corn proteins are low in tryptophan compared to wheat and rice proteins.

Industrial synthesis

Nicotinic acid was first synthesized in 1867 by oxidative degradation of nicotine. Niacin is prepared by hydrolysis of nicotinonitrile, which, as described above, is created by oxidation of 3-picoline. Oxidation can be effected by air, but ammoxidation is more effective. In the latter process, nicotinonitrile is produced by ammoxidation of 3-methylpyridine. Nitrile hydratase is then utilized to catalyze nicotinonitrile to nicotinamide, which can be transformed to niacin. Alternatively, ammonia, acetic acid and paraldehyde are utilized to make 5-ethyl-2-methyl-pyridine, which is then oxidized to niacin. [84] New “greener” drivers are being evaluated utilizing manganese-substituted aluminophosphates.

that usage acetyl peroxyborate as non-corrosive oxidant, preventing producing nitrogen oxides as do conventional ammoxidations.

The demand for business production consists of for animal feed and for food fortification suggested for human intake. According to Ullmann’s Encyclopedia of Industrial Chemistry, around the world 31,000 lots of nicotinamide were sold in 2014. [4]

Mechanism of action

Niacin carries out a number of functions in the body therefore has lots of systems, not all of which have actually been fully described. Niacin can reduce lipids and apolipoprotein B (apo B)- containing lipoproteins by modulating triglyceride synthesis in the liver, which degrades apo B, or by regulating lipolysis in adipose tissue.

Niacin prevents hepatocyte diacylglycerol acyltransferase-2. This action avoids the last step of triglyceride synthesis in hepatocytes, limiting available triglycerides for extremely low density lipoproteins (VLDL). This activity also results in intracellular destruction of apo B and reduced production of low density lipoproteins, the catabolic product of VLDL.

Niacin also prevents a high density lipoprotein (HDL) catabolism receptor, which increases the levels and half life of HDL. [5]

Advantages of niacin

While more research studies require to be carried out and supporting proof should be identified, there are a variety of uses for niacin. In regards to health advantages, niacin potentially can:.

• Control cholesterol
• Lower blood pressure
• Enhance mental health
• Clear skin
• Handle migraines
• Promote joint health
• Secure cognitive function
• Assistance digestion
• Lessen abnormality
• Improve impotence

It assists manage cholesterol levels

In some cases niacin is recommended together with cholesterol-lowering medications like statins to help stabilize blood lipid levels. It can increase high-density lipoprotein (hdl) cholesterol, which is the healthy sort of.

Cholesterol, by 15% to 35%. And it can decrease low-density lipoprotein (ldl), the bad cholesterol, by 5% to 25%.

Other evidence shows that niacin benefits people with an increased danger of heart attacks and cardiovascular disease since it not just lowers ldl cholesterol but also triglycerides. Niacin can reduce triglyceride levels by 20% to 50%. The prescription solutions niaspan and niacor have fda approval to deal with dyslipidemia (elevated cholesterol or other fats in the blood).

It might reduce blood pressure

Small medical trials of using niacin have actually shown it has significant blood pressure decreasing results in people with hypertension. In addition, abrupt lowering of high blood pressure is described in the plan insert of prescription niacin. Nevertheless, in larger clinical trials involving niacin and niacin-containing regimens there revealed either no clear considerable effects of niacin or slightly lower mean high blood pressure among some niacin treatment groups compared to placebo.

More research studies require to be done to identify how reliable niacin can be for reducing blood pressure and minimizing the risk of cardiovascular events, however so far the research study appears promising.

It might improve mental health

Dietary routines have a substantial influence on numerous mental disorders including anxiety, anxiety, schizophrenia, and bipolar affective disorder. This has actually caused the development of dietary standards to help handle these conditions. Niacin deficiency has actually revealed a possible link to some mental illness.

Research studies have documented minimized cerebral blood flow in depressed clients and enhanced cerebral blood flow following antidepressant treatment. Niacin is believed to increase cerebral blood circulation, so there is possible to use niacin supplements in addition to prescription antidepressants.

It benefits the skin

Niacin is a great supplement for the skin. It can help safeguard skin cells from sun damage, clear acne when used topically, and lower redness and swelling. Vitamin b3 in the formulation of niacinamide is often utilized as a natural topical skincare treatment to clear acne. Niacin can even help manage inflammatory skin conditions like bullous pemphigoid or granuloma annulare.

It may assist manage migraines

Although it’s uncertain how niacin achieves healing impacts, it could be beneficial for migraine and tension-type headaches and the avoidance of these headaches. Niacin might prevent migraine symptoms by broadening the intracranial vessels and following contractions of the extracranial vessels.

It promotes joint health

Vitamin b3 in the form of niacinamide has been shown to increase joint movement and reduce joint discomfort, swelling, and swelling. Because of its anti-inflammatory effect on joints, niacin might function as a good treatment choice for people with arthritis.

It may secure against alzheimer’s illness

In a research study released by the journal of neurology, neurosurgery, and psychiatry, dietary niacin was concluded to be a possible protector against alzheimer’s disease and age-related cognitive decrease. A greater consumption of niacin might be related to a slower rate of cognitive decline over time.

It’s good for food digestion

Niacin is excellent for the digestive system since vitamin b3 assists break down nutrients like carbs and fats into energy. If somebody lacks niacin, they might have a difficult time digesting food and might experience gastrointestinal issues with time.

It may avoid abnormality

According to a 2017 research study released by the brand-new england journal of medication, niacin supplements during pregnancy avoided malformations in mice. More human research studies require to be done, however preliminary research suggests that niacin may assist avoid nicotinamide adenine dinucleotide (nad) abnormality in humans and lower total abnormality rates.

On the other hand, care is encouraged for niacin supplements while breastfeeding, as there is minimal human data on the results of niacin in breastmilk. New or anticipating mothers need to always speak with their healthcare provider prior to introducing new supplements or medications during pregnancy or lactation.

It might enhance impotence

Erectile dysfunction (ed) is the failure to get or keep an erection. Because niacin helps improve blood circulation, it might also be good for impotence. In a study released by the journal of sexual medicine, a daily dosage of as much as 1,500 mg of niacin was enough to enhance sexual function amongst males who had both ed and dyslipidemia. Guy with dyslipidemia were studied due to the fact that dyslipidemia is closely related to ed. [7]

Niacin deficiency

Etiology of niacin deficiency

Primary niacin shortage

It results from very inadequate consumption of both niacin and tryptophan, which generally takes place in locations where maize (indian corn) makes up a considerable part of the diet plan. Bound niacin, discovered in maize, is not absorbed in the intestinal tract unless it has been formerly treated with alkali, as when tortillas are prepared. Corn protein is also deficient in tryptophan. The high incidence of pellagra in india amongst individuals who eat millet with a high leucine material has led to the hypothesis that amino acid imbalance may contribute to deficiency. Deficiencies of protein and numerous b vitamins commonly accompany main niacin shortage.

Secondary niacin deficiency

It may be because of diarrhea, cirrhosis, or alcohol addiction. Pellagra also may occur in carcinoid syndrome (tryptophan is diverted to form 5-hydroxytryptophan and serotonin) and in hartnup disease (absorption of tryptophan by the intestinal tract and kidneys is defective). [8]

Reasons for niacin shortage

One type of niacin shortage results from a deficiency of niacin and tryptophan (an amino acid). This form causes a disorder called pellagra, which impacts the skin, gastrointestinal system, and brain. Pellagra develops only if the diet plan is deficient in niacin and tryptophan because the body can convert tryptophan to niacin. People who live in areas where maize (indian corn) is the main food source are at danger of establishing pellagra due to the fact that maize is low in niacin and tryptophan. Moreover, the niacin in maize can not be soaked up in the intestinal tract unless the maize is treated with alkali (as it is when tortillas are

Prepared). Pellagra may be a seasonal condition, appearing each spring and lasting through the summer, when the diet consists mainly of maize products.

Pellagra likewise develops in individuals who have among the following:

• Hartnup disease, an unusual genetic condition in which absorption of tryptophan is impaired
• Carcinoid syndrome, an unusual disorder in which tryptophan is not transformed to niacin

The following can lead to a shortage of niacin:

• Alcohol addiction
• Diarrhea
• Cirrhosis
• The antibiotic isoniazid if taken for a long time

Symptoms of niacin shortage

Usually, people with pellagra establish a symmetric, dark red rash that looks like a sunburn and becomes worse when it is exposed to sunlight (a condition called photosensitivity). The rash occurs in locations of sun exposure, and its location is unique:

• On the arms and hands (like gloves)
• On the feet and calves (like boots)
• Around the neck (like a locket)
• On the face forming a butterfly shape

Skin abnormalities are relentless, and the impacted areas may end up being brown and flaky.

The entire digestion tract is impacted. The tongue and mouth may end up being swollen and dark red. The tongue might swell, the mouth may burn, and sores might establish on both. The throat and esophagus may also burn. Saliva production might increase. Other signs consist of nausea, vomiting, stomach pain, constipation, and diarrhea (which might be bloody).

Later, fatigue, sleeping disorders, and passiveness establish. Malfunction of the brain (encephalopathy) normally follows. It is characterized by confusion, disorientation, hallucinations, and amnesia. Individuals might be overexcited, depressed, very elated (manic), delirious, or paranoid (thinking that individuals intend to damage them). [9]

Diagnosis

In early deficiency, medical diagnosis needs a high index of suspicion and attempts at verification of niacin shortage. Niacin metabolites, especially n-methylnicotinamide, can be measured in the urine. Low levels recommend niacin deficiency but might likewise be found in clients with generalized under-nutrition. Serum and red cell levels of nad and nadp are also low but are likewise nonspecific. In innovative cases, the medical diagnosis of pellagra can be made on clinical grounds. [10]

Treatment

Normally a niacin deficiency might suggest multiple dietary deficiencies; for that reason, a balanced diet is a strong suggestion. Nicotinamide dosages of 250 to 500 mg/day orally need to be provided. Despite nicotinic acid being the more common type of niacin, nicotinamide is used for niacin deficiencies as it does not trigger symptoms such as tingling sensation, itching, or flushing. Patients with pellagra should avoid sun direct exposure and alcohol consumption. The recommended dietary allowance (rda) for niacin is expressed as niacin equivalents (ne). The rda for children ages 1 to 3 and 4 to 8 years of age is 6 and 8 mg/day of ne. For both young boys and girls ages 9 to 13, the rda is 12 mg/day of ne. For individuals 14 years or older, the rda is 16, and it is 14 mg/day of ne for males and females, respectively. Rda during lactation is 17 mg/day of ne. [11]

Conclusion

The function of niacin as an antioxidant micro-nutrient has been established in a variety of research. The systems through which niacin safeguards the body versus oxidative tension can be maintaining the glutathione redox cycle, and also, reducing nadph/total nadp+ ratio in addition to increasing the nad+ material. Nevertheless the majority of the examinations in this area are restricted to speculative studies, these mechanistic research studies can be beneficial for additional clinical development of niacin and niacin-related compounds for the treatment of oxidative tension and its complications.
