When I first tried it, I experienced a flushing symptom about an hour later. I still feel it occasionally, but I've adjusted, and the symptoms have diminished over time. It enhances blood circulation throughout my body and positively affects my skin and mental wellbeing. I also feel it is working on my skin's pores.

Supports vascular system
2 people found this helpful
I take niacin to strengthen my vascular system due to some existing issues. The product works well; however, I do notice a reddening of the skin and increased warmth after a while. Generally, I am satisfied with this supplement, as it has a vasodilating effect, which enhances blood flow and improves overall metabolism.

Skin and hair improved
2 people found this helpful
After taking niacin, I felt a distinct tingling and rush of blood to my face, neck and back within half an hour. This did not cause discomfort; rather, it felt pleasant. I've noticed improvements in both my skin and hair since starting this supplement.

Good quality product! The packaging is convenient and the dosage excellent. I am pleased with the results; the medicine definitely works. The tablets are small, making them easy to swallow, and have a neutral taste. I bought niacin to enhance blood circulation in my organs and joints, particularly as there are inflammatory processes. Alternating it with niacinamide has also increased my energy levels; I'm sleeping less now. Highly recommended!
