I am sure this is a great product

I am sure this is a great product. Quickly found Niacin is one more thing I am allergic to. So disappointed.

scary and dangerous experience

Posted by iHerb Customer on Sep 26, 2017 | Verified Purchase

the dosage is 10 times what you should take. 500 mg is way too much. I had the worst discomfort of my life, i turned very red and itchy and had heart palpilations. The "flush" was on my head, ears, neck, legs , pelvis , pretty much everywhere i felt hot and looked red. Definetly do not take this high dose, i had to change my plans that day just because i was so red and itchy. Almost panicked and went to the ER, but I knew from online sources it is not dangerous. It was still very uncomfortable and itchty and I had to hide in my room because i looked scary like i was having a full blown allergy attack.

Thanks for your feedback!

Good product but magnesium stearate

Posted by iHerb Customer on Sep 18, 2017 | Verified Purchase
