Today, I will be reviewing BPI Sports B4, a thermogenic fat burning supplement that claims to do more than just help you lose body fat.

This product is also marketed as a pre workout that can increase your energy level, focus, and endurance so you can train better.

While I've always been skeptical of "hybrid" supplements like this, I still gave it a shot to see how it performs.

Now, let's delve into whether BPI Sports B4 lives up to the promises and whether it's worth your investment. As someone who has personally used this thermogenic supplement, I'll share my experiences and insights.

What is BPI Sports B4 Thermogenic?

Close up image of BPI sports B4 Thermogenic

BPI Sports B4 Thermogenic is a once-daily thermogenic fat-burner that may help increase your energy, improve your mood, and eliminate body fat. This supplement is an "adipose tissue regulator" that targets areas in your body where it's harder to burn fat.

With its thermogenic properties, using this product can also serve as a metabolism booster that raises your body's energy expenditure. This, in turn, helps your system tap into stubborn fat reserves and burn them as fuel for energy.

B4 also delivers a central nervous system stimulant designed to keep you energized and increase your focus. Supercharging this effect is caffeine anhydrous, the stronger form of caffeine that provides a sustained energy boost.

This product also contains a dopamine modulator designed to enhance your motor control, motivation, and endurance so you can enjoy longer and more intense workouts.

Given its stimulating effects, BPI Sports also touts B4 Thermogenic as a pre workout that can be taken on training days and rest days for continuous fat-burning support.

For best results, the brand recommends that you take one pill 20-30 minutes before exercise.

Now let's get to the most crucial part - the ingredients.

What Are the Ingredients of BPI Sports B4?

Supplement facts of BPI sports B4

As a certified fitness trainer with extensive experience in the field of nutrition and supplements, I've thoroughly examined the ingredients of BPI Sports B4. This supplement boasts niacin, caffeine, dendrobium nobile stem, psoralea seed, and red wine concentrate. I'll delve into the ingredients of the product, sharing my personal experiences with each and their potential benefits, providing a more comprehensive understanding.

Let's take a look at each of their benefits below.

Niacin (30 mg)

Also known as vitamin B3, niacin is an important nutrient that comes in two main chemical forms: nicotinic acid and niacinamide or nicotinamide.

The one in B4 is the former, which is known to lower cholesterol levels and reduce heart disease risk.

Also, your brain needs this nutrient to get energy and function properly. In fact, a niacin deficiency is associated with brain fog and even psychiatric symptoms.

Caffeine (as caffeine anhydrous)

This is a highly concentrated form of caffeine powder noted for its ability to stimulate athletic performance and aid in weight loss.

Caffeine is also known to reduce fatigue, intensify concentration, and improve endurance. Because of these benefits, it has become a popular ingredient in pre workout supplements.

Dendrobium (Dendrobium nobile) (stem)

Dendrobium

Dendrobium, a member of the orchid family, has been used in traditional Chinese medicine for centuries as a remedy for thirst, fever, diabetes, infection, inflammation, cancer, and more.

This ingredient is added to some pre workout supplements to help enhance physical and athletic performance. Some chemicals in dendrobium might also lower blood pressure and reduce pain.

However, none of these results have been studied in humans.

Therefore, there is little evidence proving that these purported claims are legitimate.

Sword bean (Canavalia gladiata) (seed)

This edible legume is another popular ingredient used as a traditional medicine in China.

Red and black sword beans were discovered to be rich in the antioxidant phenols, a quality attributed to their red and black bean coats, which have extremely high phenolic content [1].

Therefore, sword bean has potential health advantages, such as preventing cellular damage due to free radicals.

Psoralea (Psoralea corylifolia) (seed)

Psoralea

This herb is noted for its role in menopause and fighting estrogen deficiency symptoms.

Psoralea has also been shown to play a role in bone regeneration and could possibly have anti-stress and antidepressant effects [2].

However, both of these studies have only been tested on rats. There is currently limited evidence of psoralea's benefits for humans.

Japanese sophora (Sophora japonica) (leaf) (Quercetin)

This one contains the flavonoid quercetin, which is known as a free radical scavenger.

This component may help improve your exercise performance and reduce your blood pressure and blood sugar levels.

It's also known to have anti-hemorrhagic and anti-inflammatory properties [3].

As promising as these benefits are, more research is needed to prove their legitimacy.

Red wine concentrate

Red wine

This dry powdered product provides the same health benefits as wine minus the alcohol.

Researchers have long believed that red wine can lower your risk of developing heart problems.

Resveratrol, an antioxidant compound found in red wine, has been shown to have potential antiviral, anti-inflammatory, and anticancer properties.

Despite resveratrol’s popularity as a supplement, the above results haven’t been studied well in humans.

Yohimbe extract (bark)

This tree contains a compound called yohimbine in its bark, an element used as an aphrodisiac and a sexual performance enhancer.

It is commonly used to treat erectile dysfunction, boost athletic performance, and aid in weight loss [4].

However, there is very little research showing how yohimbine can benefit humans.

Pros and Cons

I try to be as objective as I can, and here’s the pros and cons list I came up with after all the testing and research I did.

Pros
  • Contains potent stimulants that enhance the product's energizing properties
Cons
  • Proprietary formula conceals exact dose of ingredients
  • Contains many ingredients used in herbal medicine that have understudied effects on humans
  • The potential harmful consequences of yohimbe extract are quite alarming

What Are the Potential Side Effects of BPI Sports B4?

A woman coughing

Based on my personal experience, I want to highlight potential side effects of BPI Sports B4, including the well-known "niacin flush." This phenomenon can lead to sensations like flaring, tingling, itching, and skin reddening, particularly if you exceed the recommended dosage.

Each capsule of B4 Thermogenic contains precisely 30mg of niacin, which is just below the recommended daily intake of 35 mcg.

This fat burner is likely safe, but some of its ingredients may cause unpleasant reactions if you go above the suggested use, so be mindful of your intake.

Serious side effects are most likely if you take between 2,000 to 6,000 mg of niacin a day. - Mayoclinic.org

Another thing worth pointing out is this supplement’s yohimbine content, which comes with some potential dangers.

The primary concern about products containing yohimbe is the inaccurate labeling of the supplements and the possible life-threatening events they may cause.

According to a study, the most common side effects of supplements using yohimbine are gastrointestinal distress, elevated heart rate, anxiety, and high blood pressure. A few individuals even experienced a heart attack, seizure, and acute kidney injury after taking yohimbine products [5].

However, these cases resulted from supplements containing a mix of yohimbe and several other components,  like caffeine, which could have aggravated the ingredient's adverse side effects. And if you're having any of the side effects, we recommend you to opt for some proven stim-free fat burners instead.

For females, we recommend checking out the best fat burners for women.

Customer Reviews

Woman giving thumbs up to B4 Thermogenic

To offer a more comprehensive view, let's explore user feedback on B4 Thermogenic. Now, let's consider the user perspective. BPI Sports B4 has garnered a range of reviews, from glowing 5-star ratings to concerns and complaints. I'll provide an overview of what actual users have experienced to give you a well-rounded view.

Now, let's delve into some user feedback that offers valuable insights.

“I love this fat burner from BPI Sports! I have never taken a pre-workout or thermogenic that comes in a capsule so I wasn’t sure what to expect, but I was pleasantly surprised. This supplement helps me endure a two hour workout and it makes me sweat a lot. I would definitely buy again.” - Ashley F.

“If you want to get the jitters that you can't get through your workout, then this supplement is for you. I was so unbelievably nauseated that I thought I had the flu. It also gave me a really bad headache. It's the worst fat burner I've ever taken!” - Aaron S.

“I’m not sure if I had an allergic reaction to the diet pill or not, but my entire body got very red upon taking this weight loss supplement. I also felt extremely sick, hot, nauseated, and dizzy. I had severe chills and flushing. I’ve never had such a bad reaction to any supplement before.” - Allen H.

Fat Burner Alternatives

To help you make an informed choice, let's compare BPI Sports B4 with some of its direct competitors in the fat burner market. This will give you a better perspective on where it stands in terms of ingredient transparency, safety, and overall effectiveness.

PhenQ

PhenQ is a fat burner packed with all-natural, scientifically-tested ingredients that target everything from stored fat to energy levels, appetite, and fat production.

While BPI Sports B4 and PhenQ use caffeine, PhenQ also includes capsimax and L-carnitine to increase metabolism and boost energy.

Additionally, PhenQ’s formula includes nopal and chromium to regulate appetite, a benefit that our test group applauded because there was a significant decrease in snacking and food cravings over several weeks of use during the testing phase.

As a fitness trainer, I like that PhenQ has a transparent label with each ingredient dose listed clearly, a benefit lacking in BPI Sports B4 because of its proprietary blend.

I discussed PhenQ with our dietitians, specifically ingredient quality and dosing, and confirmed it is a formula that could effectively help many people lose weight.

Vintage Burn

Vintage Burn is a thermogenic fat burner with a unique formula that focuses on preserving muscle mass while shedding unwanted fat.

Vintage Burn's ingredients boost metabolism and mood, suppress appetite, and enhance focus. Some key components include green tea extract, raspberry ketones, and caffeine.

Let's compare the caffeine content in both products, breaking down the exact milligrams you get per serving to help you make an informed decision.  Vintage Burn stands out for its emphasis on preserving lean muscle mass, which the results of our test group support with their before and after body measurements.

Vintage Burn prioritizes lean muscle preservation, while BPI Sports B4 focuses on enhancing mental clarity, mood, fat burning, and appetite control. This distinction is vital for tailoring your choice to your fitness objectives. This distinction is important for you to consider when choosing the right product for your fitness goals.

Vintage Burn may hit your wallet harder than BPI Sports B4. Still, It is a supplement from a reputable company with a transparent label, which is something, as a fitness coach, I consider invaluable.

Instant Knockout

Unlike BPI Sports B4, Instant Knockout is a vegan-friendly fat burner initially designed with maximum ingredient doses to cater to bodybuilders and athletes.

Enhancing metabolism and encouraging thermogenesis with a generous 300 mg of caffeine Instant Knockout can assist in fat shredding. However, those sensitive to stimulants may prefer to seek an alternative.

Furthermore, Instant Knockout incorporates appetite suppressants like Glucomannan and chromium, which produced positive results from our test group regarding reduced snacking.

The measurements taken before and after the testing phase yielded positive results for improved body composition.

Our dietitians liked the inclusion of L-theanine for its ability to improve mental alertness and focus, enabling individuals, like myself, to power through intense workouts.

Comparatively, Instant Knockout does come at a higher price point, but this cost reflects its premium ingredient doses and transparent label, which provides clarity on what you're getting for your investment. Consider your budget and specific fitness goals when weighing this price difference, as it could play a significant role in your decision-making process. Still, with higher ingredient doses than most fat burners on the market and a transparent label, Instant Knockout is an excellent choice for professional athletes and everyday gym-goers alike.

BPI Sports B4: Should You Buy It?

Drawing from my personal experience with BPI Sports B4, I'll provide insights into this product from a user's standpoint, including both its benefits and limitations.

First, this fat burner supplement contains a mishmash of under-researched ingredients that are potentially harmful.

It has a proprietary blend, which means users have no way of knowing how much of each ingredient they are actually getting. And to me, that's already a major red flag.

However, if you're seeking an alternative that aligns better with safety and transparency, I'd recommend considering PhenQ as a more effective and trustworthy choice.

This weight loss supplement gives pretty much the same benefits as B4, except that this one is made with natural and safe ingredients that have been proven to support weight loss.

The brand is also transparent about what goes into their formula, which is a quality that I'm sure many avid supplement consumers would appreciate.
