NO FLUSH Niacin 👍🏻

EXCELLENT for heart %26 cellular health. I really like that it is a "no flush" Niacin, so you'll never get that uncomfortable flushed feeling.

Good Vitamin Supplement

My husband's cancer doctor prescribed this because of the vitamin's statistical success in preventing a reoccurrence. I have purchased this brand many times because I am confident in its quality.
