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

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.

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.

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.

    Nice product, but gave me side effects

    These pills have been both positive and negative for me. The positive is that they came in a much lower dose than most other brands, which is important if you want to start small in case of side effects. Unfortunately, they also caused headaches, so I'm not too thrilled about that. I do like that the capsules are a smaller size than an average pill capsule.

    Work Great

    These work great for me to balance my methyls. The dose is perfect. Does it make me flush? Yes, on the rare occasion. Usually when I haven't eaten anything. It's uncomfortable (or more so embarrassing) for a few minutes but goes away quickly enough.
