Active form of vitamin B3
Verified Purchase
Niacinamide (vitamin B3) is important for supporting the nervous system; reducing tiredness and fatigue; improving energy metabolism; maintaining healthy skin; preventing vitamin B3 deficiency in gastrointestinal problems. Niacinamide from NaturesPlus is available in the form of tablets, the size of which is medium, with a fairly large dosage, so it is important to introduce it gradually to avoid allergic reactions due to the influx of niacin.

These vitamins have truly exceeded my expectations! After using them regularly, I’ve noticed a big improvement in my overall well-being — I feel more focused, my mood is better, and I don’t get tired as easily. The packaging is convenient, and the dosage is just right. It’s great to finally find a product that actually delivers what it promises.

Good dosage, good form for absorption. to support healthy skin, nervous system and cardiovascular system, as well as for energy metabolism. It helps regulate the work of the sebaceous glands, reduce inflammation and redness of the skin, improve its elasticity and hydration, and also supports the proper metabolism of carbohydrates, fats and proteins.

Affordable and high quality
Verified Purchase
I give my son, who's going through puberty, 500mg of niacinamide daily. His face doesn't break out easily, and his skin is much better. We've already gone through 3 or 4 bottles. My skin is fantastic when I take 1000mg.

The quality of the niacinamide ingredient is good.
Verified Purchase
The size is just right, making it easy to take. It provides folic acid energy, and since it is a niacin flush, I think it will be effective for the nervous system if taken consistently. The packaging is also neat.

I like Nature's Plus.
Verified Purchase
I ordered this because the quality and ingredients are both excellent. I think I absolutely have to take niacinamide. The packaging is nice, and I think it will be effective if I take it consistently.

Niacinamide
Verified Purchase
I heard that niacinamide was good for you, so I took it on the recommendation of Dr. Tokumi Fujikawa. I didn't experience the niacin flush when I took this. It has no taste and the size is just right.
