If you want niacin but hate that hot flush feeling, this is a great option.
I’ve bought this more than once because it works well for me personally.
No weird side effects, and I feel comfortable taking them every day.
Good supplement choice when you want niacin without the typical flush reaction.
The capsules dissolve easily, no bad aftertaste or weird texture.
Two bottles for the price is a good deal if you’re planning to take these long term.
Wish the bottle had a resealable cap, but otherwise pretty decent.
Took me a couple of weeks to get used to these, but no flushing is a big win.
Overall satisfied, the product matches the description perfectly.
I appreciate the no-flush formula; it makes daily use more pleasant.
The packaging is good and the capsules don’t have a strong taste or smell.
Haven’t noticed any flushing since starting this, would recommend if you’re sensitive.
Easy to incorporate into my supplement stack without any uncomfortable side effects.
Works well for my daily vitamin routine, and no flush means I can take it anytime.
I can take these without worrying about looking like I just ran a marathon.
Received two bottles for a deal and that saved me some money, definitely worth it.
A convenient way to get my B3 without that intense warm flush feeling.
Capsules are soft and swallow easily, which is a big plus for me.
I’ve tried other niacin supplements but this one is by far the best for avoiding flush.
No flushing whatsoever and the size of the capsules is just right.
I like that I can take my niacin without the usual uncomfortable redness.
Good price for the quantity, and the capsules are easy to take every day.
Takes a bit to start feeling the benefits, but no annoying skin flush at all.
These capsules are easy on my stomach and I didn’t experience any flush, which is great.
