21st Century Niacinamide 500 mg Prolonged Release Tablets, 110 Count

I’ve been taking 21st Century Niacinamide 500 mg Prolonged Release Tablets (110‑count) daily for a few weeks, and I’m pleasantly surprised by how consistently my skin and energy feel. The prolonged-release formula means each tablet releases evenly throughout the day, so I don’t experience any of the flushing or irritation I’ve had with other niacin supplements. Just one tablet in the morning with breakfast is all it takes to keep things steady.Aside from mild skin-brightening and hydration support, I’ve noticed my energy levels feel steadier—no typical midday dips or fog. The bottle is large and lasts a long time, and the tablets are easy to swallow. Overall, it’s a solid, budget-friendly choice for anyone seeking the benefits of niacinamide without the usual side effects or needing frequent doses.

This is one of those supplements that you never knew you needed.... Melatonin gets one to sleep fast, but this keeps me sleeping soundly throughout the night without any grogginess in the morning.

This is a quality product however, it has calcium in it. This can be problematic for people who avoid supplementing with calcium who are prone to atherosclerosis or calcification in arteries. Although it is clearly on the label, it seems unnecessary for a product also labeled as support for "energy and circulatory."

Works really well, I had Bariatric surgery years ago and also am on wegovy. I had noticed my energy levels were slumping and my pcp recommended I add this to my supplement regimen which is pretty strict as it is. I take b12 this multi probiotic etc. well let me tell you this bottle is economical extremely well worth it. I can tolerate it with or without food. Plus 110 tablets that’s like 4 months worth

I used very small amount so this bottle will last a long time.

Great Supplement

I checked the ingredient label for sodium but it may be the magnesium in not sure. Nonetheless I really wanted include this in my daily routine but I have stop taking the supplement.
