We’ve all struggled to find the right diet product, so we took the time to create an in-depth review, examining the ingredients, side effects, customer service and clinical studies of BPI B4. We focused on numerous dieter comments and experiences from all over the web. Finally, we condensed and summarized to give you the info you need.

BPI B4 Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is BPI B4?

First off, BPI B4 ingredients are caffeine anhydrous, dendrobium noble, canavalia glandiata seed, psoralea corylifoia, sophora japonica leaf, red wine concentrate and pausinystalia yohimbe bark. The supplement promotes weight-loss by boosting fat loss and accelerating thermogenesis. It’s taken once a day, prior to exercise.

BPI B4 was introduced in 2013 and it is touted as super-powerful and “ultimate” extra strength. The official website and trusted retailers sell the supplement. We like that it contains a few natural ingredients and that we located some positive customer comments, but read on…

Lack of Results – “No Changes?”

The first issue we came across with BPI B4 ingredients was a lack of results. “Based on the profile, it contains components that could cause spark metabolism,” said our Research Editor. “But, it’s evident after looking at customer reviews, that this diet aid doesn’t work well for everyone.”

One user said, “There was really no major effect from using this product, other than having to go to the bathroom a little more than normal. Other than that, I saw no noticeable weight loss.”

According to another dieter, “In all honesty, this stuff is terrible. I took it for a whole month while working out and it did absolutely nothing for me.”

BPI B4 Serious Side Effects – “Watch Out!”

There are dozens of customer complaints regarding BPI B4 side effects. In fact, one user stated, “I don’t think any vitamin or supplement has ever left me feeling so sick. Within the hour, I am lightheaded and nauseated. My head hurts.”

“Nausea, vomiting and jitters. Extreme high pulse. Don’t recommend it. Just horrible feeling, not worth it,” said another customer.

“Every time I took it I would feel sick to my stomach!,” said yet another user.

According to our research, if a certain aspect of a weight-loss supplement is problematic, like causing adverse reactions, the probability of long-term success is slim. In other words, if BPI B4 does cause harmful side effects, this could be a major issue.

The Science – “Any Proof?”

We were unable to find any documented scientific evidence backing the weight-loss claims made about BPI B4 capsules. The official website does not provide any science at all. We know there is evidence behind caffeine as a stimulant and metabolism booster, but that ingredient can be found in thousands of supplements. Since we at DietSpotlight need to see published clinical studies supporting the diet product and how it assists with weight reduction, we can’t get behind BPI B4.

The Bottom Line – Does BPI B4 Work?

Are you ready for the final word on BPI B4? It’s clear this one is marketed as an extremely powerful thermogenic, but the customer reviews we found online say otherwise. Therefore we are skeptical about recommending this diet formula. It’s also important to factor in the numerous user complaints about side effects like headache, stomach pains and nausea. Furthermore, there does not appear to be a satisfaction guarantee provided for BPI B4.

Those who wish to drop more pounds and slim down, we recommend a weight-loss product that contains safe ingredients, is backed by clinical studies and does not cause harsh side effects.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This weight-loss formula uses a unique blend of four ingredients, which have been shown in documented scientific studies to help increase metabolism and improve overall fat loss. We haven’t found any talk of negative side effects and dieter reviews posted online reveal people are seeing good results.

Additionally, the producers of Dietspotlight Burn are so very confident in the product that they’re offering a Special Trial Offer, which is a good sign.

According to the website, this product is high-end and dual-performance. Unlike many weight loss pills, this supplement is mostly geared toward guys.

Some of the notable ingredients used in BPI B4 are Caffeine (a stimulant and diuretic that ignites energy levels), Yohimbe Bark (aids with fat loss), Red Wine Concentrate (contains antioxidants and may support heart health), Sophora Japonica, Psoralea Corylifoia, and Dendrobium Nobile.

BPI B4 Conclusion

It is unclear what makes BPI B4 so “effective.” While this supplement does contain caffeine to boost energy levels and stimulate the metabolism, most of the other ingredients are not elaborated on. This factor alone is enough to deter some dieters. On a separate note, it is obvious that BPI B4 is intended for men who exercise regularly. This is why this supplement is for improved endurance and performance levels.

This is a pre-workout pill that aids in sport performance and weight loss.

Hello.This post was really motivating, particularly since I was searching for thoughts on this issue last Thursday.

  Took it and...
Rafael (Verified User)

I took this dietary supplement today before my cardio and on an empty stomach, during and after my workout i felt sick and felt like i was about to vomit and pass out. I stopped working out and try to do some deep breathing, help me a bit. I then head to school and my classmates told me i was pale, i had to go head back home early. After eating a meal tho i now feel better, not a 100% ok but better. I think my mistake was taking it on an empty stomach. I won’t take it tomorrow as i have to catch up for my workout plan.. I’ll give it a shot the day after tomorrow, not on an empty stomach this time and maybe comeback here for a follow up feedback 😊
For now 2.5 stars

  Avoid it at all costs !
Tammi (Verified User)

Felt awful an hour after taking it on an empty stomach as recommended by GNC, headaches, jitters, stomach upset, nausea, increased thrist and diarrhea. Avoid at all costs!


I have been taking this product for about two months, not every day, but maybe two times a week before my weight lifting and cardio works outs and it WORKS VERY WELL for me..
In my opinion this works well, but you also have to work you butts off, not just take it and think that it’s going to magically make you thinner, I had No side affects but I also do not take it on an empty stomach, I take it about 3 hours after my meal and it gives me so much energy and the extra boost to complete my work out, I think you might have other issues going on with your body Jeremy.

   I felt sick had to pull over cause

I was given B4 sample by a GNC store manager. I am a nurse and work 12 hour shifts, so I am frequently exhausted. I took this and was so sick. I usually drink 3-5 cups of coffee per day, so I ruled out caffeine sensitivity. I was so nauseous, my heart rate was in the 120’s, I was flushed and sweating through my scrubs. My pupils were dilated and I was shaking. I actually had to leave work. I was sick all day long. I noticed when I read other reviews, most positive comments were from specifically men that have used workout stimulants before. I did read up on the ingredients, and the dendrobium works like, and has a similar chemical composition of amphetamines. Just a word of advice from a naive, had to learn the hard way this time girl; not everything from a health food store is safe. Know what the ingredients are and what their mechanism of action is before taking an supplement.

  happy with the results
vince (Verified User)

I have started to use this product 5 days ago and I am losing about a pound of weight each time I go to the gym. I don’t think that people will have the same results as me I am an advanced lifter and have a lot of muscle and I think it’s helping with the weight loss but I had belly fat I could not get rid of and I’m becoming very lean. I am very happy with the results. I will post back when I have reached the 2 week mark or until all b4 has been taken


I have been taking BPI B4 thermogenics for a while now and this product worked very well for me i did not have any of the side effects that are being said here but everyone is different.The best thing to do is try it for yourself.

  Can BPI B4 works for me?

I have recently went to my GNC store and talked with a associate there who recommended this for me to loose my belly fat that I can’t get rid of while working out. I’ve read that this is mainly used for men so I’m kind of wondering now if this is the right product for me. Can someone help


I’m 24 and getting married in a few months and want to lose the few extra stubborn pounds I haven’t been able to shed. My local GNC recommended this for me. However after reading side effects I’m apprehensive. I would love to hear everyone’s feedback on this product before I start taking it. Thank you.


Hello Jennifer,

I’ve been taking the product for 5 days now and have notice a trimming of my belly fat. My love handles are disappearing and the stomach is smaller than before. But, I also take the nite fat burner and put on my elastic stomach support (the one I use when I work out) and I am looking better in my clothes….my stomach is not as obvious. Last thing, I stopped working out to see how good it actually works. I will give you an update next week. Good luck!


just started on Saturday. will let people know in a few weeks.
