We’re always keen to hear about the latest supplements on the market, and we were recently introduced to Cellucor SuperHD Xtreme.

Cellucor is one of the most popular fitness supplement brands out there right now, so we were intrigued to take a look at their latest offering.

The SuperHD range is a popular one, so what’s different about the ‘Xtreme’ version?

Does this particular product live up to the marketing hype? Let’s take a close look at Cellucor SuperHD Xtreme to find out.

What does SuperHD Xtreme do?

As you’ve definitely already work out, SuperHD Xtreme fits into the broader range of supplements commonly known as so-called ‘fat burners’.

A so-called ‘fat burner’ is a blanket name which refers to (usually) plant-based food supplements that are designed to help support your goals.

Before we get started, it’s important to realise that most of the supplements in this category, including the one featured on this page, have not been proven to help with fat loss and fat burning.

They are supplements designed to support your goals and that usually contain a number of plant extracts and other ingredients such as vitamins and minerals.

SuperHD Extreme is marketed as a supplement with a “powerful intensifier”.

That all sounds great, but is this supplement all it’s cracked up to be? Let’s find out by taking a close look at the ingredients.

What you need to know about the ingredients

Let’s start this section by taking a close look at the exact ingredients listed on the label of SuperHD Xtreme.

SuperHD Xtreme ingredients

The first disappointing thing we noticed about this product is that Cellucor have decided to use a proprietary blend called the ‘SuperHD Xtreme’ blend.

We hate proprietary blends because it means that you don’t know the individual doses of the ingredients used, and instead are only shown the total blend dose.

This makes it very tricky to assess the actual effectiveness of the product and it’s not something we like to see. There are no excuses for supplement manufacturers not being totally transparent with their ingredients in this day and age.

So with that mini-rant out of the way, let’s focus on what this product does contain. The top ingredients are:

• Caffeine Anhydrous – It was good to find this on the label because it’s one of our favorite ingredients. Caffeine is usually added to the top products in this category.

• Cayenne Pepper – Another one of our top rated supplement ingredients. Cayenne is usually found in the top products in this category.

• Caffeine Pterostilbene Cocrystal – This is another source of caffeine just like the Anhydrous version (our preference) listed above. The problem here is that because of the proprietary blend, we don’t know the doses of the ingredients. Too much caffeine can cause side effects.

• Rauwolfia Vomitoria Extract – We’re not too sure about this ingredient. We haven’t seen it included in many simialr supplements before and it’s only available via a prescription in the UK. It seems like something of a risky inclusion to us.

What’s missing?

Although SuperHD Xtreme does tick some boxes when it comes to using some the best ingredients around, it falls quite a way short in our opinion.

For starters, there was no Green Tea Extract in this supplement, which is one of our top-three rated ingredients along with Caffeine and Cayenne Pepper.

Also missing were some of our other favorite ingredients such as Green Coffee Bean Extract and Glucomannan, which is a dietary fiber which comes from the root of the Konjac plant.

We recently updated our list of the leading fat metabolisers as well as our pick of the best supplements for women on sale right now.

Are there any side effects?

Generally speaking, you shouldn’t run into too many side effects with modern food supplements because they tend to only use natural ingredients.

That being said, there are a couple of warning lights when it comes to SuperHD Xtreme, namely the stimulant content.

Because they use a proprietary blend, we don’t know exactly how much caffeine is in each dose, and that’s not good. Too much caffeine can cause side effects such as the jitters and energy crashes.

As mentioned above, we’re also not too sure about the inclusion of Rauwolfia Vomitoria as an ingredient. It’s not legal to use it in supplements in the UK.

We always recommend doing your own research into the ingredients before taking a new supplement for the first time.

It’s always a good idea to speak to your doctor before thinking about trying any new supplement for the first time.

How to take SuperHD Xtreme

Each bottle of SuperHD Xtreme contains 60 capsules.

That means that if you stick to the recommended dose of two capsules per day, one bottle will last you for around a month.

The label says that you should take one tablet, twice a day, once in the morning and once again in the afternoon.

This isn’t ideal in our opinion. We prefer supplements that require you to take them at least three times a day, so your body can benefit from round-the-clock ingredients.

There’s a warning on the packaging saying not to take it any less than six hours before going to sleep at night.

What are customers saying?

We found lots of reviews of Cellucor SuperHD Xtreme on Amazon.

At the time of writing this post, it had an average rating of 3.6 out of five stars.

One happy customer said that it helped to support them on their journey.

Someone else said that they lost “a little bit” of weight while on Super HD Xtreme.

However, there were also some negative reviews. Someone said that they had a terrible allergic reaction to the product including blistering bumps and swelling of the skin.

Another customer said that it made them “warm” for a few hours but had “no effect” otherwise.

Is this the best supplement?

Not in our opinion. Although it does contain a couple of good ingredients, there are too many things missing.

It’s also let down by the fact that it uses a proprietary blend and doesn’t list how much caffeine is in each tablet.

Anything else to consider?

As we always like to remind our readers, there’s no such thing as a magic supplement when it comes to your health and fitness.

You should always make sure that your eating right, training hard and getting plenty of rest before considering taking any kind of supplement.

That said, a quality product can help to support you when combined with the right nutrition and training regimes.

Review conclusion – our final thoughts

So that wraps up our review of Cellucor Super HD Xtreme.

This product disappointed us overall, mainly because it uses a proprietary blent and so we don’t know the individual doses of the ingredients on the label.

It was also a shame to see some of our favorite ingredients such as Green Tea extract not included.

We can’t help but feel that there are some much better products on the market right now.
