Niacinamide

Niacinamide

Niacinamide is the amide form of vitamin B3. It makes NAD via the salvage path; dermatology topicals and oral nutrition both commonly use this molecule.

Primary

Supports cellular energy metabolism

Niacinamide refills NAD via salvage; glycolysis and DNA-repair PARP both consume this coenzyme pool. Most B-complex tablets use the amide form. People who need B3 energy production and want face and neck to keep an ordinary color in meetings more often come to this molecule.

Primary

Improve the skin barrier

Stratum corneum ceramide synthesis and epidermal-cell energy both connect to NAD. Topical niacinamide is common in moisturizing formulas; oral use refills the whole-body coenzyme pool. For dry flaking and a weak barrier that also needs B3, this amide joins skin care and cellular energy production on the same molecule.

Fatigue

Niacinamide refills NAD via salvage; glycolysis and DNA-repair PARP both consume this coenzyme pool. People who cannot get going by day and feel foggy in the afternoon more often notice stamina for tasks and mental freshness after several continuous weeks.

Dry skin

Stratum corneum ceramide synthesis and epidermal-cell energy both connect to NAD. People whose calves or cheeks feel tight and flaky more often notice moisture and less itch after several continuous weeks.

Pellagra

Niacinamide refills NAD via salvage; glycolysis and DNA-repair PARP both consume this coenzyme pool. When exposed skin reddens and flakes and gut and mood move together, people more often notice skin and spirits after several continuous weeks.

Dyslipidaemia

Niacinamide refills NAD via salvage; glycolysis and DNA-repair PARP both consume this coenzyme pool. People with high fasting lipids and an oily diet more often notice lab markers and a lighter body after several continuous weeks.

With foodBest taken with food (not on an empty stomach) to reduce stomach upset and flushing
Best timeMorning or midday
SolubilityWater-soluble

Check the amount and unit of the active ingredient per serving first.

General wellness16 mg NE/day for adult men; 14 mg NE/day for adult women
Specific needsThe adult daily safety upper limit is 35 mg NE (from niacin supplements, to limit flushing/liver injury); high-dose therapymay only be prescribed by a clinician.

How oftenGenerally use the recommended daily intake.

Cautions

High-dose niacin for lipids must be prescribed and monitored by a clinician.

People with liver disease, peptic ulcer, or diabetes should ask a clinician before high doses.

Interactions

  1. Lipid-lowering drugs / statins (additive liver risk with high-dose niacin)
  2. Glucose-lowering drugs (may affect glucose control)
Common side effects

· Niacin flush, burning, or itching

· Nausea or stomach discomfort

Rare but important

· Long-term high doses may cause liver injury and raised blood sugar.

Long-term dependenceNot addictive; flushing from high doses may lessen with tolerance, but that does not mean you should raise the dose on your own.
