Who Needs Niacin

Brain fog, skin issues, digestive problems, and some mental disorders are associated with niacin deficiency. However, niacin’s most notable role is supporting heart health via normal cholesterol regulation.

Niacin contains 50 mg NE of pure niacin (as nicotinic acid) per single capsule serving.

Niacin capsules by Seeking Health provide niacin as nicotinic acid. This pure form of niacin, unlike other forms (e.g., niacinamide or inositol hexanicotinate) has powerful benefits for cardiovascular health.

Each convenient capsule contains 50 mg NE (niacin equivalents) of niacin, also known as vitamin B3. For an optimally-absorbed lozenge form, consider our Niacin Lozenges.

Niacin plays significant roles in your brain, gut, skin, cardiovascular system, and DNA. Niacin needs increase during stress, injury, and sunlight exposure. Because the body cannot store niacin, it requires adequate intake of this critical vitamin daily.

Niacin is vital for the proper functioning of all cells. In particular, brain and nervous system cells require niacin for serotonin production. As a precursor of both tryptophan and serotonin, niacin supports a healthy mood.

Niacin supports healthy aging by acting as an antioxidant and aiding in normal DNA repair.

Niacin is a building block for NADH/NAD+ and NADPH/NADP+. These compounds are used by cells to make energy. Niacin also supports healthy digestion. It helps your body break down and produce energy from carbohydrates, proteins, and fats. Digestive issues are one of the first signs of niacin deficiency.

Niacin has the well-known effect of causing vasodilation, often called the niacin “flush.” This causes small blood vessels to open for increased blood flow. Healthy blood flow is important for cardiovascular health. It also helps with the normal removal of toxins stored in fatty tissues into the bloodstream, so they can be removed from the body.

Niacin in the form of nicotinic acid has well-established positive effect on lipid levels. It may support healthy HDL and LDL cholesterol levels and overall cardiovascular health.

Niacin also supports healthy skin by supporting normal moisture retention, elasticity, and tone. Niacin may also support healthy cartilage.

Niacin metabolism requires a lot of methyl groups. Its activity as a ‘methyl consumer’ may help reduce the side effects of high-dose methylated nutrients.

Niacin (as nicotinic acid) supports:

  • Cardiovascular health
  • Energy production
  • Healthy metabolism and weight management
  • Detoxification
  • Digestive health
  • Skin and cartilage health
  • Positive mood and cognition
  • NAD+ and NADPH levels
  • Tryptophan and serotonin levels
  • Normal cholesterol levels
  • Side effects from methylated nutrients

Niacin capsules by Seeking Health are gluten-free and dairy-free. They are also free from artificial colors, flavors, preservatives, GMO markers, and common allergens.

Customer Review

Great Dosage

I love the low level dosing of this Niacin. I can dose as needed rather than taking a massive quantity. I still get a flush if I haven't taken it for a while but the flush is minor at this dose & doesn't bother me. ~Melissa C

Key Ingredients In Niacin

  • Nicotinic Acid:This pure form of niacin supports healthy cholesterol levels, cardiovascular health, cognitive function, methyl group side effects, and energy production.

Why Niacin Works

Niacin capsules by Seeking Health provide 50 mg NE of niacin (vitamin B3) as nicotinic acid. This form of niacin plays essential roles in maintaining healthy skin, energy production, cardiovascular function, serotonin production, detoxification, digestion, and more. Low levels of niacin can disrupt these functions.

Low niacin can lead to accelerated aging and age-related cognitive declines. Deficiency often presents with skin issues and digestive problems. Certain psychiatric disorders are also associated with niacin deficiency.

Niacin is a precursor of both tryptophan and serotonin. Niacin levels can become depleted with increased serotonin needs. Likewise, serotonin production is reduced when niacin levels are low.

After being absorbed from food or supplements, niacin is converted into its active coenzyme forms. These include nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADPH). Over 400 different enzymes require NAD+ and NADPH as coenzymes, primarily for redox reactions. These coenzymes can quickly transfer electrons back and forth with other compounds. This electron transfer catalyzes chemical reactions and regenerates compounds in the body, such as glutathione.

For example, glutathione acts as your body’s master antioxidant. It does so by donating its electrons to things like hydrogen peroxide to facilitate their elimination from the body. NADPH is the compound that regenerates glutathione’s ability to act as an antioxidant again and again. NADPH and NAD+ are some of the most important coenzymes in the human body. Their activity is directly influenced by the availability of niacin as a building block.

Niacin capsules by Seeking Health provide niacin in the bioavailable form of nicotinic acid. This form has unique benefits for cardiovascular health. If you’re looking for the same great formula in an optimally-absorbed lozenge, consider our Niacin Lozenges. Experience the difference that pure niacin can make with Seeking Health’s Niacin capsules.

How to Use Niacin

Suggested Use

Take 1 capsule daily with food or as directed by your healthcare provider.


Do not use if tamper seal is damaged. Children and pregnant, lactating, or breastfeeding women should consult their healthcare provider for medical advice prior to use.

Niacin Flushing: This formula contains niacin. When taken on an empty stomach, a healthy response to niacin supplementation may include mild blushing, warming, or tingling of the skin. This can appear on the ears, face, arms, torso, or occasionally on the legs. Commonly referred to as a "niacin flush", this harmless response normally dissipates within an hour. It is related to niacin's role in vasodilation (widening of blood vessels). Vasodilation leads to better circulation, capillary flushing, and increased blood flow to the surface of the skin. To minimize or prevent flushing, consider taking this supplement with food or in divided doses.

How to Enhance Niacin


Consider Pulsing

Dr. Ben Lynch recommends using certain dietary supplements based on your need for them. Start with a partial serving and increase slowly over time to the full serving, only if needed. When you start feeling good, consider reducing the serving size, skipping days, or pausing supplementation. Then take again when you feel you need it (stressful day, traveling, chemical exposure, etc.), hence "pulsing." Work with your qualified healthcare practitioner to determine what's best for you.
