My friend had high blood pressure. Her situation improved after taking niacin and taking a daily walk. Please click the thumbs-up icon if you find my review helpful. Thanks!

I have been using this product Niacin B3 for quite some time now and have found its flushing effect which is what I am using for to be excellent. I have recommend my friends to try this B3 and to-date they have all been very pleassed with the potency and quality and its effect.

Having this important ingredient in tablet form is great as my doctor told me to start with a small dosage of 25 mg which means I had to quarter the tablet. Even at that, it caused a horrible niacin flush. I will work up slowly to get to where he suggested for my metabolism.

The quality of this product is very good. The size of the package is not big for me to store. The ingredient is also good for me. The benefits include giving my brain great energy and lessening my stress. My age looks like smaller and my immunity becomes stronger. It tastes very good.

Niacin works extremely well in reducing bad LDL and triglycerides cholesterol and increasing HDL, the good cholesterol. It does provide a flushed feeling if taken in larger doses. I'm starting at 100mg and build up to 300mg per day, to see how well I tolerate the flushed feeling. I've used other products by Source Naturals and I found them to be of excellent quality.

Great price and even greater product. This is an everyday supplement I take. Anti-aging, enery boosting, the list goes on. Start off with 1/day if you're just starting out & take with food.

niacin improves circulation, suppresses inflammation and helps the body make various hormones in the adrenal glands and other parts of the body. when i started with 100mg it caused the niacin flush for 30 min. now it doesn't anymore and i'm taking 200mg

These tablets are small and easy to take. Many people are deficient in niacin. I recommend to research niacin and what it does. Source Naturals makes a quality product and it's a good value for the price.

This product is very good. I am willing to introduce this product to my acquaintances I like it so much that I highly recommend it I've never seen a product like this before. At this price, it seems to be cheap compared to its merits

Been taking these for about 3 weeks, one tablet a day (100mg) as recommended. I definitely feel more energized during the day. I chose this instant release version over the sustained release (non-flush) version as it is reported to be less toxic to the liver. The flushing is mild, a little redness on the face, ears and forearms. After a week there is no more flushing. Good product, excellent value for money imo.
