Niacin SR™: A Practical Guide to Sustained-Release Niacin (and Why People Use It)
Niacin, also known as vitamin B3, has a long history in the wellness world, especially when the conversation turns to cardiovascular support and blood lipid balance. But if you’ve ever tried niacin before, you’ve probably heard about (or experienced) the infamous “niacin flush.”
That’s where Niacin SR™ (Sustained-Release Niacin) comes in. This formula is designed to release part of the niacin quickly, while the remainder is released gradually over several hours, with little or no flushing for many people.*
Below is an educational breakdown of how sustained-release niacin is intended to work, what it is known for supporting, and the full ingredient list based on the information provided.
What makes sustained-release niacin different?
Standard (immediate-release) niacin can hit fast—and that rapid rise is often linked to the warm, red, tingly flushing sensation some people feel.
Niacin SR™ is designed to spread the release, delivering some niacin right away and then releasing the rest over several hours.* The goal is a smoother experience and reduced flushing for many users.*
What niacin is used for: cardiovascular + lipid support
Niacin has been found to support blood lipid levels related to healthy cardiovascular function in several ways:*
1) Supporting healthy cholesterol balance*
Niacin may support cardiovascular health by:
Reducing the production of LDL and VLDL in the liver *
Increasing production of beneficial HDL, which helps draw cholesterol away from the lining of the arteries *
2) Helping with triglyceride metabolism*
Niacin is also described as removing triglycerides from the blood through a process called *“lipoprotein lipase activity.”
3) Supporting circulation*
Niacin is noted for its ability to dilate blood vessels, which can support circulation.* The information provided also suggests it may aid in flushing out existing plaque.*
(Quick reminder: lipid and cardiovascular support is a big topic—if you’re working on cholesterol, triglycerides, or circulation, it’s always wise to do it alongside lab work and guidance from a healthcare professional.)
