B4 Thermogenic is a health supplement made by a company called BPI Sports. It’s designed to help support your goals.

This product is designed to be taken once a day and is supposed to give you a boost as you take responsibility for your results.

In this review article, we’re going to take a close look at the ingredients of B4 Thermogenic and also check out some of the customer reviews to determine where it stands in comparison to some of the other similar products out there at the moment.

Let’s first take a quick look at what this product is supposed to actually do.

What does B4 Thermogenic do?

Just in case you hadn’t already guessed, B4 Thermogenic fits into the broader range of health supplements referred to as so-called ‘fat burners’.

B4 Thermogenic differs from a lot of the similar supplements out there at the moment because it only needs to be taken once a day.

The promotional material promises that B4 Thermogenic will help to support your goals as you look to achieve your best results.

That all sounds great, but how does this product actually compare to the other top ones out there at the moment? Let’s take a close look at the ingredients to find out.

What you need to know about the ingredients

The first thing we found when looking at the label of B4 was that it includes a proprietary blend. This is not a good thing because it means that we don’t know the individual doses of all of the ingredients.

Instead, the manufacturer has chosen to hide the individual doses within a larger blend.

We don’t like this at all as it makes it very difficult to assess the quality of the product if we don’t know how much of each ingredient is included.

Generally speaking, we tend to avoid products that use proprietary blends, because they mean that you do not know the exact doses of each ingredient in the capsule.

Let’s now take a look at the ingredients that are featured on the label (but without their doses).

• Caffeine Anhydrous – This is a good start because caffeine is our of our top-rated ingredients. Coffee drinkers will need no introduction to caffeine – it’s one of the most popular stimulants on the planet! Again, though, it’s disappointing not to be able to know exactly how much caffeine is in this supplement, as the dose is masked within a proprietary blend.

• Dendrobium Extract – We have not seen this ingredient included very often in any supplements. There appears to be little scientific research into the is substance and this is the first supplement we’ve come across that contains Dendrobium Extract. We’re not too sure about its inclusion in this product.

• Yohimbe Bark Extract – Again, this is not an ingredient we like to see used in any kind of supplement. It’s not got a great deal of evidence backing it up and it’s been linked to some side effects.

There are plenty of other ingredients in B4 Thermogenic. You can check out the full ingredients list below. As we mentioned above, we’re not too happy about the fact that the individual doses of the ingredients have been masked in a proprietary blend.


What’s missing?

Although B4 does contain one of our favourite ingredients in the form of Caffeine Anhydrous, there are far too many things missing for us to consider this as one of the top supplements out there at the moment.

Firstly, there was no Green Tea Extract, which was a big surprise. This is one of our favourite ingredients and usually makes it into the top products in this category. Green Tea is also a natural source of caffeine.

We were also disappointed not to find Glucomannan on the label. This is a dietary fiber which comes from the root of the Konjac Plant and is a common inclusion in supplements of this type.

There was also no Cayenne Pepper, one of our favorite ingredients found in this type of supplement.

There were also quite a lot of other things missing when compared to our favourite ingredients. This included Green Coffee Bean Extract and Chromium, which can contribute to normal macronutrient metabolism.

Are there any side effects?

The first thing to do when considering a new supplement is to check the label carefully to make sure that you’re not allergic to any of the ingredients.

However, these types of supplements are usually pretty safe because they tend to contain commonly-used ingredients.

One thing to bear in mind is the caffeine content. Although we don’t know exactly how much is included in the supplement because of the proprietary blend, it would probably be wise to take this product as early in the day as possible to avoid it messing with your sleep.

We’d also recommend drinking plenty of water with this kind of supplement.

As always, we also recommend speaking to your doctor before thinking about taking any supplements at all.

How to take B4 Thermogenic

Each bottle of B4 Thermogenic contains 30 capsules, which is a month’s supply.

The label says that you should take one capsule between 20 and 30 minutes before training at the gym.

As we’ve already mentioned we’d recommend not taking this supplement too close to bedtime as the caffeine content could mess with your sleep.

It’s also probably worth reading up about the individual ingredients to see if any of them cause any side effects or if people have reported issues with them.

What are customers saying?

We found a lot of reviews of B4 Thermogenic on sites such as Amazon.

One customer said that they loved the product and that it had given them great energy for their workout.

However, one user complained that they felt too awake at night after having taken the product in the early evening before working out.

Someone else complained that it left them with an upset stomach.

Is this the best supplement?

Not in our humble opinion. Although B4 Thermogenic does contain some decent ingredients, we feel that there are some much better products out there at the moment that don’t contain proprietary blends.

We recently reviewed and picked out our favorite supplements on sale at the moment based on the ingredients and customer feedback. Click the link below to check out the list.

Anything else to consider?

We always recommend that you first try and make sure that your diet and exercise regime is in check before trying a supplement like this.

You shouldn’t expect a supplement to do the hard work for you. Make sure you’re training hard and eating right before taking it.

A supplement can help to support you on your journey, but your priority should always be to make sure that you’re exercising regularly and sticking to a good diet first.

Review conclusion – our final thoughts

So, is B4 Thermogenic a supplement you should consider taking? Here are our overall thoughts in a nutshell:

• Contains caffeine
• You only have to take it once a day

• Uses a proprietary blend
• Missing a lot of our favorite ingredients
• Mixed reviews

So there you have it, our full review of B4 Thermogenic by BPI Sports. We’ve broken down the product to see how good the ingredients are and have also checked out some of the customer reviews.

Overall, we’re not too convinced about this product. It’s a shame that the ingredient doses are masked in a proprietary blend and some of our favorite substances are missing.

All in all, we feel that there are some other better products out there at the moment.
