## Description

Real Niacin provides niacin in an 8-hour extended-release form that enables you to enjoy the health benefits of niacin without experiencing the uncomfortable skin flushing that commonly accompanies other forms of niacin. Niacin comprises approximately 200 coenzymes that play pivotal roles in metabolism and energy production within the body. Additionally, research suggests that niacin, in combination with a well-balanced diet, may help to maintain healthy cholesterol levels that are already within the normal range.

Review: LIPID MANAGEMENT - Hello All, i just wanted to give some brief up front information on Niacin's effectiveness. i will update as time goes on . i am a registered pharmacist and have been in practice for over 20 years. I have always been a big advocate of herbal medicine and regardless of what mainstream medicine says ..they play a strong role in disease management, more than you think. I can tell u honestly that Allopathic doctors (MD's ) are way too pen happy when it comes to writing prescriptions . This is largely due in part to the kickbacks they receive from Big Pharma for writing as many legend drugs as they can get on a prescription pad!! this is my opinion only. Statin drugs are way over prescribed these days and they have their flaws i can attest!. SE'S include muscle weakness; can precipitate type 2 diabetes (it may be small chance but if u are borderline diabetic they can tip you over the edge) To be brief they are not for everyone. Niacin , or Nicotinic acid on the other hand is a form of Vitamin B3 . it's a natural product unlike statin's that are 100% man made .you want the more natural product. Niacin can control your lipids very well , just as well as statin's or better (they raise HDL or good cholesterol better than Statin drugs) .Also they are a lot cheaper than statins especially if you are not on a prescription drug plan. With that out of the way my past experience with Niacin has been very good if not excellent . Previously in 2016 my LDL was 183 and HDL was in the low forties ; total cholesterol was 260 if i can remember correctly . The PA-C at the MD's office got frightened and wanted to put me on a statin drug. I said NO!! There are placebo controlled studies in several American Medical journals that strongly support the use of Niacin. After Niacin therapy for several months my LDL dropped to about 130 and my HDL went up to 48, my TC down to 200 . i recently a week ago went back on this brand DR' s Best so like i said previously i will update as time goes on but i expect this Niacin to preform very well. it is a desertcart best so i expect it to follow through. I'll let you know. Yes, there are SE's with Niacin ..the flushing and the itching which are very real I know . taking a slow release from helps with this and try taking it right before bedtime helps also (cholesterol production is highest while we sleep) . In conclusion i would highly recommend speaking with your doctor about the benefits of Niacin over statin therapy for Lipid Management. There are a lot of theories ,opinions out there about treating High cholesterol and you need a doctor who will listen to you and "think outside the box" about how to treat your high lipids . Many of them just follow a Logarithm taught to them and move on to the next patient ! You get my drift. This is my professional opinion only
Review: Great niacin supplement, but nearly impossible for me to swallow. - Let me begin by saying that I take a few other supplements (multivitamin, immune booster, etc) and they are fairly large. But they are all gel capsules which makes them swallow-able for me. But these niacin tablets get stuck in my throat and cause a lot of pain. Not fun at all. So I just up and decided to toss one tablet into my nutribullet with my usual smoothie ingredients. Problem deliciously solved. The blades make short work of it and leave no discernable trace. Shortly after finishing the smoothie I feel some flush (not uncomfortable for me) so I know I'm absorbing the niacin. Awesome. Been doing this for several months and I recently had my annual physical. My cholesterol levels were all at normal levels and my HDL (good cholesterol) was rising (doc says that's a good thing). Very pleased with this product. I was very worried that I'd have to cut these tablets with a pill splitter and then hope the little shards didn't get lodged in my throat. But I discovered that blasting them into a million tiny granules accompanied by fruit and other yummy flavors was the way to go for me.

### ⭐⭐⭐⭐⭐ This is the Form of Niacin that Studies have Shown Lowers Cholesterol
*by T***G on November 30, 2016*

All Niacins are NOT the Same - THIS is the form of Niacin that Lowers Cholesterol. My doctor discontinued my statin drug because of liver issues, and prescribed 500 mg. of Niacin 2x a day. So I got some Niacin at the local dollar store and started taking it faithfully. I took it for months but my cholesterol remained unchanged. So I decided to look up the study where Niacin was found beneficial and I discovered its not ANY Niacin, but a SPECIFIC TYPE. It named a particular kind of Niacin. I looked, and the kind from the dollar store was NOT that kind of Niacin. So I came to Amazon and found Doctor's Best, which IS the kind of Niacin that lowers cholesterol. I have been taking it ever since and my cholesterol has slowly but surely been lowering. In 2016, my cholesterol was 221, LDL 137. Without making any changes to diet or exercise, but by adding this type of Niacin 2x day, in January of 2019, now my cholesterol is 188 and my LDL is 113. That's pretty good for not changing anything else! I have had zero side effects with Doctor's Best - No flushing, and no other side effects at all. Highly recommend! I will continue to buy this Niacin.
