I’m taking this to help with my histamine levels. I’ve only been on it a month but I’ve been able to reduce my antihistamine by half!

Great quality !!!
I have used this brand for both flush free niacin and tri magnesium. I have found both products to be of great quality . Don’t buy drug store brands that are frequently lower potency. Go with a pharmaceutical grade product like this and you will get better results

I love my Flush-Free Niacin. Much better than taking Statins for my cholesterol control.
I am allergic to Statins and needed something to help regulate my cholesterol. My Flush-Free Niacin is easy to take twice a day and it has helped lower my cholesterol without the dangerous side effects of Statins. I am extremely happy to have an alternative to a medication that caused me to ache all over and is not linked to future memory impairment.

Pure brand
This brand was specifically recommended by my doctor for being the purest form of Niacin. That’s good enough for me!

I will continue to take this great product for the rest of my life
I take this product for keeping my cholesterol within normal range. I take this once a day with organic garlic twice a day and the last tie I had my cholesterol checked all is well. I will continue to take this great product for the rest of my life. And I love Integrative Therapeutics products as I consider them a “pure” ingredient. Better than the off the shelf niacin with a lot of glucose added in for pill formulation.

Wow..does what it says!!
I purchased this product after having a very alarming flush response to a generic Niacin product. I’ve been taking this for almost a week and no flushes. Great value for the money.
