Best 10 Benefits of Niacin

Vitamin B3, also known as niacin, is an essential nutrient required for everyday function. Deficiency in this vitamin can lead to skin problems, memory loss, and even hallucinations or cognitive impairment. On a more positive note, here are ten benefits of regular niacin consumption:

1. Maintains lipid levels

The body needs a healthy balance of lipids, including cholesterol and triglycerides. Niacin promotes low levels of LDL cholesterol and higher levels of HDL cholesterol, and prevents the body from holding on to too many triglycerides.

2. Promotes healthy skin

Is your skin damaged by acne scars or rosacea? Niacin may be able to help. Proper intake nourishes the skin and can reverse damage caused by severe acne and other skin problems, and has even been shown to reduce the risk of skin cancer.

3. Prevents cognitive impairments

Niacin is known for its antidepressant properties and ability to promote brain repair. Aging adults may find niacin beneficial in preventing dementia, Alzheimer’s, schizophrenia, and other cognitive disorders associated with old age.

4. Treats diabetes

This vitamin helps maintain a healthy blood sugar level. Niacin is also useful in preventing diabetes-related conditions such as heart disease.

5. Prevents pellagra

Pellagra is a serious result of niacin deficiency and can only be treated with high doses of the B complexes, the most useful of which is nicotinamide.

6. Relieves arthritis

Niacinamide has been found to reduce join pain and inflammation in patients with osteoarthritis; additionally, it is known to promote muscle growth.

7. Prevents birth defects

Nicotinamide adenine dinucleotide (NAD) is responsible for DNA synthesis. Research has suggested that regular niacin intake by pregnant women ensures the proper function of NAD and prevents maldevelopment and birth defects in unborn children.

8. Treats erectile dysfunction

Niacin acts as a vasodilator, allowing blood flow to the genitals during intercourse, thereby allowing men to achieve and maintain an erection.

9. Relieves motion sickness

Niacin, particularly when taken from papayas, has been shown to be instrumental in reducing motion sickness.

10. Aids in digestion

Vitamin B3 aids in the digestion of fats and carbohydrates; a deficiency can lead to stomachaches, constipation, and other indigestion disorders.
