B-3 Nicotinamide 500 mg 100 Capsules - Natural Flush-Free Vitamin Formula | Gluten-Free Nicotinic Amide Niacin | Supports Skin Health | UV Protection | Healthy Cell Repair
  • SUPPORT YOUR SKIN'S NATURAL DEFENSE MECHANISMS: Recommended by dermatologists, Nicotinamide may support the body's natural defense mechanisms that are activated when the skin is exposed to harmful UV radiation.* This valuable supplement is ideal for men, women, and aging individuals with sensitive or susceptible skin!*
  • HELP SUPPORT THE BODY'S NATURAL RESPONSE TO SKIN BLEMISHES. Nicotinamide can help support your body's natural response to skin blemishes by supporting the skin's natural ability to regenerate a smooth outer layer clear of blemishes, red spots, bumps, and warts.* Preliminary clinical evidence suggests that nicotinamide may help support the body's natural ability to control Polymorphous light eruption, a type of photosensitivity.
  • SUPPORT YOUR ENERGY LEVELS. Do you suffer from fatigue and low energy levels? There are many, many reasons for this condition that affects so many. One reason could be inside your cells - when they don't have the necessary nutrients to metabolize energy correctly.* Nicotinamide may support the body's natural mechanisms that improve energy production due to its role as a precursor of NAD, an important molecule involved in energy metabolism.*
  • Nicotinamide is well tolerated. Nicotinamide is a different form of vitamin B3 to nicotinic acid or niacin. Nicotinic acid commonly causes headaches, flushing and low blood pressure, but these side effects are generally not seen with nicotinamide.* Preliminary evidence suggests that nicotinamide may support the body's natural ability to support healthy joint mobility and comfort, while other studies have shown that nicotinamide may support healthy blood glucose levels.*
  • SATISFACTION GUARANTEED. Every product we ship from our US-based NSF GMP certified, FDA-inspected facility is designed to support your health, happiness, and overall well-being. We are so confident in our quality control processes, that we offer a no-questions-asked 60 day money-back guarantee on our products.

Top 10 Benefits of Vitamin B3

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.
