Dr. Berg Niacin 500mg with Flushing for Heart Health & Energy Support* - 100-Day Supply Vitamin B3 Niacin from Dr. Berg Recommended Nicotinic Acid - 100 Capsules

The product arrived in great condition, securely packaged with easy-to-swallow capsules. When I first took it, I experienced mild body itching, which I found out can be a normal reaction to vitamin B3. Still, it seems like a high-quality supplement.

I love Dr. Berg’s supplements and it’s now the only brand I trust and I knew there was a flush as I’m no stranger to niacin. It was a little intense and I’m sure I’m the first to say this, but I like the flush. It’s blood flowing more freely through the body and something about that makes me feel better, lol I’ll definitely continue to take it and recommend this brand. The flush can be a little intense but it’s worth it! I originally bought the product to help with depression and I’m glad I did. Thank you Dr. Berg!

Took one capsule on empty stomach first thing in the morning, I had a severe reaction to this high dose of B6. My entire body was on fire, lips were swollen, skin was bright red with tingling, itching, scratching. After 3 hours it dissipated and I slept all day into the evening. I was totally exhausted from my body being lit up. I didn't read the bottle that said don't take on an empty stomach but had planned to eat as soon as I took it and it kicked in before I could eat. Plus it says you may have tingling on the bottle. I think this high dosage is unsafe whether you eat or don't eat. It's in the garbage and I have unsubscribed from Dr. Berg's channel.

I watch Dr. Berg quite regularly on Youtube and thought I'd give this product a try. When it comes to the Niacin flush, I usually enjoy that feeling you get from drinking a C4 when that beta alanine makes your skin crawl, but upon reading some of these reviews, I thought I'd start with only half a dose to be safe. About 20 minutes after taking a half dose, my skin felt like I had received the worse sun burn of my life. I think I will take a quarter dose next time and work my way up. Dr. Berg did talk about the importance of Niacin in his video, and I trust him. Just be prepared for a crazy flush.

Yeah I had no idea about the flush either. Had me freaking out a bit thought I might explode but a lil chat with Grok calmed me down. I was ready for it the next day. I noticed after the flush I felt pretty good and not just body. The past few days I noticed I have been looking forward to it. I was a lil disappointed today the flush has gotten milder n didn't last as long. I still feel pretty great. I think the surprise is better. Happy I didn't know. It made every nightmare review way funnier to read. Sorry if I spoiled it for you.

Works great had flushing the first night. Scared me to death

This itching sunburn effect is intense! I’m staying relaxed, drinking electrolytes and having faith in this process. I buy Dr. Bergs products all the time like natural b1, electrolytes, and D3/k2 and they’re the best but maybe 300 mg should’ve been the proper starter dose.

I decided to try this to help lower my cholesterol in a more natural way. I did not know about something called Niacin flushing. I took the capsule and about 15 minutes later I had a VIOLENT reaction to it. My face turned bright red and felt like it was on fire! My husband said it looked like my face was melting!!! I was overheating, all my limbs had intense tingling and itching, my heart was racing and I was dizzy. I mean it was CRAZY and very scary. Subsequently I read this is a reaction many others experience when taking niacin. It should be in the description of this production you don’t think you’re going to die!!!! The worst of it was over in 30-40 minutes but the itching lingered. So while this product may be great for some people I don’t think I’ll ever take it again!
