Nutricost Niacin (Vitamin B3) 100mg, 240 Capsules - with Flushing, Non-GMO, Gluten Free

When I was a kid, I used to pop Niacin to help flush my system and pass drug tests after smoking a bunch of weed. Now, I just use it to flush out my system every once and a while and get the warm fuzzy feeling of my veins dilating to the maximum. My only con is the (short-term) intense stomach pain if you take them on an empty stomach. Made in the USA with globally sourced ingredients

I’ve been taking full-flush niacin daily alongside citrus bergamot, and the impact on my lipid profile has been outstanding. My total cholesterol dropped from 172 to 149, LDL from 104 to 85, and my LDL/HDL ratio improved from 2.1 to 1.7. All confirmed in my recent lab report. Yes, you get the classic niacin flush, but it’s short-lived and absolutely worth it for the cardiovascular benefits. My skin flushes for about 20-30 minutes, then I feel completely normal. The results speak louder than any marketing claims. This is one of the few supplements that truly moves the needle on cholesterol naturally. Highly recommend for anyone serious about improving lipid health through proven, science-backed supplementation.

I never experienced a flush before and had heard good things about it so I decided to try it. I took 4 of them and started to feel the flushing effects. I felt like I had gotten sunburned. My skin was turning red and I was nice and warm. I felt pretty good after. I'd say the effects lasted no longer than 30-40 minutes for me. The stuff works!

I need to wait until my next blood test to see if this really helps my cholesterol. The first few doses I definitely flushed. Like Red Hulk flushing! But with lots of water and time my body adjusted. Now I don’t flush at all.

Love this supplement. Be warned, it does cause a flush. I find it feels good but my husband hates it. After the flush i always feel very energized. The flush causes a red rash all over the body for approximately 30 min to an hour. Lots of tingling and even raised bumps. It looks like an allergic reaction but its not. It's perfectly fine. It will pass fairly quickly and it's actually really good for your body.
