Niacin flushing out of the blue?

I just had an odd reaction to my B complex/niacin that I can't quite figure out. For the first time ever, I had what I *think* was a full blown niacin flush from this supplement. Basically, about 15 min after taking I started feeling tingling and burning on my scalp and ears, which then spread to my face and limbs with blotches of bright red. I have been taking this supplement for years and this is the first time this has ever happened! Here I am about an hour and a haIf later and the rash is completely cleared up.

I currently take the active B complex by Klaire labs. In addition to all the methylated B's, it contains 60mg niacin (67% niacinamide, 33% niacin.) I include this because from my research it seems relatively uncommon for people to flush on under 100mg. Just wondering what may cause flushing out of the blue like this, or if anyone has had a similar situation. Some say flushing on low doses might have to do with high histamine levels and/or methylation issues. I'm kind of scared to take it again because boy that was uncomfortable... I will also add that Ive been ramping up on my detoxing and antimicrobials but generally feeling so much better lately. Thank you guys for any input!

Bufflehead, from what is found in some sources, flushing is a common side effect of high dose niacin. Be carefull with the dose, you should moderate the intake, reduce the dose or perhaps stop for a some days to see how you feel.

Some supplements, are not reliable on doses and sometimes they put much much more than what is in the leaflet or bottle, but even then NIH advises that starting on 30mg niacin doses, you can get this side effect, although adults can take this dose, you are taking 60mg, twice as much

quote:
"The niacin that food naturally contains is safe. However, dietary supplements with 30 mg or more of nicotinic acid can make the skin on your face, arms, and chest turn red and burn, tingle, and itch. These symptoms can also lead to headaches, rashes, and dizziness."

Hope it helps.
