Vascular health improved
Effectively available and indispensable for health. It has an excellent vasodilator effect, removes atherosclerotic plaques, and lowers cholesterol and blood sugar! In the form of niacin, it causes redness and tingling, but in other forms, these sensations are absent. My parents take it regularly, and it has increased their vessel lumen and alleviated vascular spasms, restoring oxygen supply to tissues and reducing hypoxia. I also provided arginine to enhance its effects, which helps relax blood vessels. While the face may tingle and redden, this is a normal sign of vasodilation and indicates effectiveness.

Allergies relieved
I recommend this product! I started with 100mg in January and gradually increased my dosage. Initially, I felt frustration, but now I rise smoothly in the morning. My hay fever symptoms are significantly milder this year. I began taking niacin for its effects on lowering cholesterol and alleviating allergies, and I'm thrilled with the results. My cholesterol continues to decrease. The pills are convenient and small, though they can stick to the tongue, making swallowing difficult. It's better to take them with ample water.

LDL cholesterol lowered
I started with 100mg of niacin, increasing to 250mg in separate doses for a total of 750mg. My doctor advised starting medication if my next test did not show lowered cholesterol. However, I managed to pass the test multiple times without needing medication.

Wellbeing improved
Excellent! I have used 21st Century Niacin Extended Release for several months, and it is a fantastic product. Each tablet contains 500mg of niacin released gradually, averting "migraines" or "high blood pressure" associated with regular niacin. I have observed improvements in my overall health and cholesterol levels since starting. Though reactions to niacin can differ, I suggest beginning with small doses and consulting a doctor. Overall, I recommend this for heart health and wellbeing.

Circulation enhanced
I buy it for myself to improve blood circulation, as I suffer from constantly cold hands and feet. Niacin effectively addresses this issue! It is an excellent vasodilator that removes atherosclerotic plaques and lowers cholesterol and blood sugar. I take it on a regular basis. The vessel lumen increases, alleviating spasms and restoring tissue oxygenation. I also combined it with arginine for enhanced effects, as the nitric oxide it contains effectively relaxes blood vessels.
