Set up Profile nowNiacinamide is a form of vitamin B3 — specifically the amide form of nicotinic acid — that plays a central role in cellular energy metabolism. It is a precursor to NAD+ and NADH, coenzymes involved in hundreds of oxidation-reduction reactions across the body, from ATP production to DNA repair. Unlike nicotinic acid, niacinamide does not typically cause the flushing response, making it better tolerated for daily supplementation.
This supplement suits a broad range of people. Those managing fatigue, supporting skin barrier function, or looking to maintain healthy cholesterol metabolism within normal ranges may find niacinamide a useful addition to their routine. It is also studied for its role in supporting cognitive function and has attracted interest in longevity research for its connection to NAD+ pathways. It fits well alongside a B-complex or as a standalone when a specific B3 focus is warranted — for example, where a clinician has identified suboptimal B3 intake through dietary review.
Pure Encapsulations is a brand with a reputation for clean, minimal-excipient formulations, consistently favoured in clinical settings where patients have sensitivities to fillers or additives. The single active-ingredient approach here makes dosing straightforward and allows precise titration under professional guidance. As always with B-vitamin supplementation, context matters — a blood panel is the most reliable way to identify genuine need.
Niacinamide (Vitamin B3)
Follow the dosage on the packaging. The input suggests one capsule taken one to three times daily — your clinician or the label guidance will indicate the appropriate frequency for your needs. Taking capsules with a meal is generally advisable to aid tolerance.
Both are forms of vitamin B3, but niacin (nicotinic acid) commonly causes a flushing sensation — redness and warmth in the skin — due to its vasodilatory effect. Niacinamide does not produce this response, making it the preferred form for daily supplementation in most people.
Those with suboptimal dietary B3 intake, individuals interested in NAD+ support for energy and cellular repair, and people seeking a clean, well-tolerated B-vitamin option. If you are unsure whether your B3 levels need addressing, a baseline blood panel is the most useful starting point.
Generally yes, but it is worth checking the total B3 content across all supplements you are taking to avoid unnecessary excess. If you are already taking a B-complex or multivitamin containing niacin or niacinamide, speak to a clinician before adding a standalone dose.
B-vitamin effects on energy and general wellbeing are typically gradual. Most people would not expect noticeable changes in under four to six weeks of consistent use, and outcomes vary considerably depending on baseline status.
Check the packaging for capsule composition and excipient details specific to this product, as shell materials can vary. Pure Encapsulations does offer many vegetarian-capsule formulations, but we recommend confirming on the label rather than assuming.

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
