It's true...no flush, at all!

I take these for high cholesterol (as per my doctor's instructions) and am very, very pleased that the label is accurate: you truly get NO FLUSH from these! I've been taking them for almost 3 years now and couldn't be happier. Have they lowered my cholesterol? To be fair, I haven't been able to stop myself from eating my favorite goodies, so I haven't seen much of a drop in my numbers. MY bad! It's possible that these niacin pills have kept my cholesterol from climbing even higher, seeing as how my diet isn't under control. My husband also takes these, and his high cholesterol HAS gone down quite a bit (he's more careful about what he eats), so apparently they do work.

excellent

This helps with hair growth, no issues with it. I don't take it every day though, and I take it along with folic acid. It's also good for my mother who had a mini stroke since Niacin has long been used to lower triglycerides and to increase high-density lipoprotein (HDL) cholesterol. The "good" cholesterol helps remove low-density lipoprotein (LDL) cholesterol, the "bad" cholesterol, from the bloodstream.

“The flavor is good and easy to take. I use this vitamin every day and the quality is excellent. The size of the bottle is convenient and lasts for a long time. I am 25 years old and this product works well for me. The package arrived safely and was well packed. Great value and I would purchase it again.”

Need more time

I have quite a high cholesterol level despite following a healthy diet, so I bought this niacin to help manage it. The capsules are quite large, but what I really appreciate is that this form of niacin doesn’t cause the hot ‘niacin flush.’ I’ll see in a couple of months whether it has any effect on my cholesterol.

Excellent No-Flush Niacin! Life Extension Nu-Flush Niacin delivers top-tier quality with clean ingredients (inositol hexanicotinate form). The taste is neutral, and the size and dosage make it easy to take daily. It boosts energy, supports metabolism, and provides niacin activity without that uncomfortable niacin flush, making it a very effective and well-tolerated supplement.

Easy to use

I use this for my school age kid and so far it works well. I mix with peanut butter and he don't notice the taste or texture difference. No side effect or anything has been observed.

Using this in the Stamets Protocol

I'm taking this as part of Paul Stamets' protocol (combined with Lion's Mane and another mushroom) for neurogenesis. Otherwise, the body uses it for DNA repair, cholesterol regulation and mitochondrial energy. I'm feeling excellent taking this, I get no flush, my nervous system is good and this supports my metabolism well.
