Niacin can lower cholesterol a bit depending on how much you take. The cheap varieties though are hard to take because of the skin flushing that occurs. The time release products generally work, I know this one does. Plus, I take it before bed and it helps me get to sleep. So there's two benefits, lower cholesterol and better sleep! Review: Natural way to help control high collesteroll - Execellent product,been taking them for years for high collesteroll. I ordered from Save Max Marketplace for the second year in a row, I give them a five star rating for their great service too.

Tho we found the flush free ones don't actually work as well for holistic depression treatment. It probably depends what you need from B3. However the flush only lasted for a few weeks total. And each "flush" was about 30 minutes total. We actually ended up going with the 100mg no time release and taking them with meals because they did cause upset stomach. **Q: I see two Rugbys here, one saying "timed release" and the other "extended release," which seem to be the same thing. Are they?** A: One is a capsule form and one is a captab form but the are the same thing **Q: Did the packaging change? The coloring on the labels are different than the ones I ordered in the past** A: Yes, almost all Rugby and Major products have gotten updated packaging. **Q: What is a captab? (How is it different from a capsule or a tablet in terms of ease of swallowing for the elderly?)** A: It has a tablet like composition in that it is not encased in gelatin but, it has a capsule shape so it’s easier to swallow. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great value, great time release so no flushing *by J***E on May 5, 2019* Niacin is a great product for folks who have high cholesterol. Niacin can lower cholesterol a bit depending on how much you take. The cheap varieties though are hard to take because of the skin flushing that occurs.
