Niacin, 500 mg , 100 Vegetable Capsules

It's one of the best supplements; the box arrived in good condition, it's very easy to take, and it has a very good effect on cellular health.

The Vitamin Shoppe Niacin (500 mg, 100 vegetable capsules) is a high-dose, pure vitamin B3 (nicotinic acid). This product is designed to support energy metabolism, improve blood microcirculation, and control cholesterol levels. 100 capsules provide over 3 months of daily use.

The dosage here is substantial—500 mg, so I started with half a capsule, even though the capsules are a bit awkward to open. The capsules are vegetarian and suitable for everyone. They don't have a strong odor. I take them in short courses to feel a boost of energy. The packaging is simple, no-frills, but suitable for home storage. The Vitamin Shoppe brand has a long reputation. For the price, it's a very good buy.

Niacin causes hot flashes, and a 500mg dose is a bit too much for a woman like me, but it is just right for men, so supplementation depends on the needs.

This ingredient is essential for the nervous system. The effects, in the form of increased energy and improved metabolism, only become noticeable after several weeks of use. This is my first time ordering from this company, and I hope for good quality.

Redness of the skin (so-called niacin flush) is not a sign of better effect or higher quality of the vitamin, but is a completely normal, expected and harmless physiological reaction of the body to pure nicotinic acid. It cannot be described as an outright "good" or "bad" sign - it is simply evidence that the vasodilation mechanism has been activated.

Good dosage of B vitamin, very nice quality brand, elegant plastic package, good amount of capsules. My mom likes it, reports no flushing. B vitamins have use in metabolism and nervous system.

Great quality and easy to take. I’m very satisfied and would definitely buy them again!
