I’ve been a big fan of Cellucor supplements, and I’m always interested when they release new products aimed at maximizing certain goals.

Our clients often need the help of weight loss supplements, either to achieve a healthier body shape or during a cutting phase.

Unfortunately, even the best supplement product designers sometimes get it wrong, so it’s important to always check test results with a dietitian.

And we’ll give you all the details from our research and testing in this Cellucor Super HD review.

What Is Cellucor SuperHD?

Cellucor SuperHD is a dietary supplement fat burner that claims to help people get rid of more body fat than through dieting and exercise alone.

The company says that it achieves such results by using proven ingredients to boost your metabolism. More on these shortly.

It could also be helpful to extend fasting periods by suppressing hunger cravings, which are often a big hurdle to weight loss.

Some users also like taking it as a pre-workout supplement, as you might feel a boost of energy and more mental focus.

These are all great claims, and our trusted dietitian covered the scientific side.

I’ve worked with Susan for many years, and she has a mountain of knowledge even when it comes to the strangest ingredients.

Here’s what she shared with us.

1. N-Acetyl-L-Tyrosine

Don’t ask; I have no idea how to pronounce it.

But apparently, there is scientific evidence that it plays a role in boosting certain brain chemicals that support you to concentrate and memorize stuff better.

I wonder if that’s Susan’s secret?

It might also aid with stress, and some of the users we talked to did mention they felt it helped them with work and study time [1].

2. AMLA Fruit Extract

AMLA fruit extract was a new one for me, and again, it seems like it was included for its nootropic type effects.

It may also provide a good boost of certain vitamins that also function as antioxidants.

Overall, not a bad ingredient, but maybe too much focus on brain boosters so far.

3. Dandelion Root Extract

Here’s the first real weight loss ingredient, and it mainly contributes by keeping your blood sugar levels more stable.

Nutrition scientists are still a little bit undecided about whether to give it two thumbs up, mainly because there have been a few studies that were inconclusive.

Personally, I think there might be enough to it, and I have seen it increasingly used in fat burning supplements, so there may well be positive benefits.

4. Yohimbe Bark Extract

If you do a quick Google search for this, then you might find a few alternative uses that claim to support certain bedroom activities.

Now, those types of activities might support you to lose weight, but we’re more interested in the direct benefits.

However, there is limited evidence that it helps with fat burning, and one study wasn’t able to find any positive results [2].

5. Capsimax Cayenne

I have seen cayenne pepper in a few different fat burner supplements, and there is a link to it boosting your metabolism.

“The main ingredient in cayenne pepper is capsaicin, which gives the spice its strong and hot flavor. Capsaicin is also the active ingredient in many treatments for arthritis and muscle pain. Some research suggest that capsaicin acts as a thermogenic chemical, which can produce heat to stimulate your metabolism and help you burn fat.” - ClevelandClinic.com.

But what I found more interesting was a study that measured hunger cravings in a group of people over 12 weeks [3]. The result showed that most test subjects thought it worked well as an appetite suppressant.

This could put an end to those unhealthy snacks that often completely mess up a diet.

6. Toothed Clubmoss

This is an ingredient we couldn't quite figure out.

There is some anecdotal evidence that it may support brain performance, and it’s sometimes used to help people with certain brain diseases.

While some boosted brain function might keep you motivated, it’s not entirely clear to us that this would be the case with toothed clubmoss.

I don’t think it’s going to do you any harm, but it’s probably not going to do all that much for your weight management.

7. Rauwolfia Root Bark Extract

This might be an ingredient that could support athletic performance.

Some research suggests that it may lower blood pressure and dilate blood vessels [4]. And more dilated blood vessels means that blood may flow more easily.

It’s what many bodybuilders look for in pre-workout supplements to gain better pumps.

But it’s not so much a performance booster, and I doubt that it will burn off some extra fat.

8. Caffeine Anhydrous

Caffeine anhydrous is probably one of the most effective fat burners as it has been proven to trigger your thermogenic metabolism.

This raises your body temperature slightly by releasing the energy stored in those love handles.

Now, there is a bit of a downside to this.

You’ll get about as much caffeine as a regular size cup of coffee. And if you’re a coffee drinker, then this could start making you a bit jittery.

You’ll also want to avoid taking it later in the day to avoid messing up your sleep.

9. Green Tea Leaf Extract

Green tea extract has many benefits, from being a powerful antioxidant to helping regulate your blood sugar levels.

“But it's difficult to dispute the nutritional benefits of this centuries-favored Asian brew, with its powerful flavonoids and antioxidants considered capable of battling chronic diseases. Now, one group of researchers claims green tea could also boost metabolism -- and help with weight loss.” - WebMD.com.

But it seems to also work well together with a large dose of caffeine, as the two may support each other in boosting your metabolic rates.

How Does It Work?

According to the label, you shouldn’t exceed two capsules per day, and I would say that you should start with just one in the morning to see how it affects you.

We asked our clients to take one serving with water in the morning and one after lunch. Fortunately, none of them reported any negative effects.

The company claims that you should start noticing increased fat loss within two to three weeks as the thermogenic boosters gradually kick into action more effectively.

While some of our clients did note that they seemed to be able to concentrate a bit better, they didn’t notice any significant difference when it came to their weight.

Pros and Cons

Cellucor SuperHD LS

One of the main issues we had, though, is the lack of transparency. You don’t get details of the exact amounts of each ingredient. It also leads us to suspect that the dosage for some of them isn’t high enough.

I mentioned above that our clients didn’t report any issues and did find it helped with concentration and motivation.

With limited positive results, we feel like this product doesn’t quite deliver on its promises.

Also, make sure you don’t take it later than mid-afternoon or within 6 hours of bedtime as it could mess up your sleep.

  • Comes in a convenient capsule form
  • Suitable for stacking with other Cellucor supplements
  • All natural ingredients with limited side effects
  • Company hides behind a proprietary blend
  • Not all ingredients are scientifically proven
  • It might cause jitters for anyone sensitive to stimulants

Cellucor SuperHD Side Effects

neck pain

Using this product is generally considered safe with limited to no side effects.

But because some of the ingredients may lower your blood pressure, it might not be that suitable for folks that take medication for such issues.

It also contains a reasonably high dose of caffeine.

That might kick start your day in the morning, but if you start your day with a cup of coffee as well, then you could end up jittery.

Customer Reviews

Cellucor SuperHD Customer Feedback

As we always try to provide balance to our product testing results, we want to show you a few online Cellucor Super HD review comments that seem to support our conclusion.

She reported that her busy work schedule and family life seemed to run a bit smoother. With more concentration and less distraction, she also had more energy to get stuff done. - Chori from Maine

Steve uses Cellucor SuperHD as part of a larger stack that has been working for his cutting phases. He’s been taking it for six months and so far thinks it works for his goals. - Steve from NYC

Dave took the capsules for two months after he hit a weight plateau. Unfortunately, it didn’t seem to help him, and switching to a different supplement gave him the boost he needed. - Dave from Aspen

He struggled with the caffeine a bit and thought it made him a bit too jittery. Even when he took the supplement just before a workout, the effects weren’t helpful. - Drew from Vancouver


Does Cellucor Super HD work?

Cellucor Super HD may work for a mental boost and limited fat loss. It’s not a magic pill to make you lose weight while you sit on the couch all day. Combined with a healthy diet and exercise routine, it has had positive effects on some people.

Is Cellucor Super Hd Safe to Take?

Yes, Cellucor Super HD is safe to take as a weight loss supplement. All the ingredients are generally classed as safe by the Food And Drug Administration, but you might want to keep to a lower dose for a few days to see if it has any negative impact on you.

How Long Does Cellucor Super Hd Last?

Some of the Cellucor Super HD ingredients might last up to 6 hours. But the thermogenic effects are most likely limited to less than an hour. That’s why a second dose might be needed to see a noticeable difference.

Does Cellucor Super Hd Have Stimulants?

Yes, Cellucor Super HD has stimulants. It contains both caffeine and green tea, which some people might be sensitive to. It’s not a very high dose, but some users have reported feeling jittery once the stimulants kick in.

Should You Buy Cellucor SuperHD Ultra?

Our ultimate conclusion in this Cellucor Super HD review is that it’s not as effective as other fat burners.

Our own test results showed limited weight loss in clients, and it didn’t speed up cutting phases enough.

The product I rely on the most for my own cutting efforts is PhenQ, and all of our clients that use it have provided positive reviews.

About the author

  • I really like this stuff! To be honest it is my first. I was hesitant about taking this because I’m not a pill person but hey there’s a bikini with my name on it that I will be in!! I am losing and shedding those extra curves on these! I don’t have any issues with side effects, my cravings at night are not as intense as prior to taking this pill and I sleep a whole lot better than ever! Thank you Isaac for the thoughts.

  • After a few days of using this product, I can say that it works pretty well! If it were not for the accidental access to your blog, Isaac, I wouldn’t have known about these products. To put things in perspective, I haven’t been having as many cravings, whereas I constantly have something in my mouth before. And I can have something small in the morning like a small bowl of fruit or two hard boiled eggs and feel completely satisfied for hours! I sleep so well with this stuff also. I have a crazy schedule and stress eating is so damn real for me, but this has truly helped and I am so thankful for that!

  • I’ve probably use this product for about 8wks now after having introduced to it in Isaac’s post. And I am pretty much done with my 1st bottle. I have noticed some changes in my weight. And let’s be honest, I could be more active and gym involved and actually could have lost some more! But “stay at home dad” you know how that goes in this society. I have lost about 5 pounds and honestly I take 1 pill at night or sometimes 2. I’m not really sure on the directions because it says 1 thing on the bottle and another on here. I don’t notice any changes in my sleep. I do have a bad case of insomnia so I just take a melatonin along with it. The pills aren’t too big and easy to swallow. Glad to discover this!

  • So it has been a while now after purchasing this with the blessing of Isaac’s words and this is what I experienced so far. I sleep like a baby and wake up refreshed not sluggish. Take 1 hour before I want to fall asleep. I have experienced weight loss, but I am following a nutrition plan to couple this with and start out walking 4 miles every morning during weekdays, combined with a complete exercise gears. After work out and by the end of day I have not noticed I walked 8000-10000 steps! I have lung complications and a mild case of asthma. So I need to take inhaled steroids. I have tried everything and had considered surgery. These were my last ditch efforts as I could never lose more than 5 pounds total which would go up and down and fluctuate so bad. I have tried other ways to reduce my extra curves and you name it, even a medical weight loss plan. All super strict following and exercising. Nothing more than 5 pounds either way. I am not a doctor, but this definitely works for my body! Love this product and am reordering once I am out of stock. Will continue with the combo till I hit my goal!! Hope to keep you posted.

  • I’ve only been on these 4 days. It took me a while to purchase as I was having doubts, until I stumbled upon Isaac’s post. I’m not sure about losing weight yet but I have noticed that I’m not bloated in the morning and my stomach has been flatter. It’s not like a diuretic or anything. I’m not sure how it works. My sleep! However, it has never been this way ever since I can remember. It has been amazing! I have so much trouble sleeping in past. I would sometimes take up sleeping pills at night to help me sleep but to no avail. But even then I would wake up 2 or 3 hours later. With this, I take it and I am passed out ALL night! Like magic! I do not wake up groggy either as I did with my previous pills. They are easy to swallow, and have no taste. I am now a fan of your for sure! Hope to learn more from you Isaac.

  • First, I would like to say thank you Isaac for taking the effort in sharing your thoughts. Okay. This product works great. But first, let’s be honest with ourselves guys, there is NO such thing as MAGIC PILLS. Nothing will work for you if you don’t make a slight lifestyle adjustment. That’s the reality. I have been taking these pills for the last 3 months and I definitely love it. It started a little slow, because it takes time for your body to adjust, but ever since my sleep has been amazing. To make things a whole lot better, I have lost 10 pounds! I cannot believe it. It has helped me with my sleep quality, bloating, gas problems and has erased my constipation issues. I haven’t experienced any negative side effects per se so I hope you guys have not as well. I suggest that you eat a light dinner early and take the pill about an hour before bed. Be patient and watch the magic unfold. To better sleep for us!

  • A little background about myself, I am a heavy eater at night because I work a graveyard shift. That is not helping my weight loss journey at all that I could only have so much self-discipline. Before, I was starving come late nights and I would cave on my way home. Junk food is all that’s open that late so I would cave and go to sleep with a fat burger in my gut when I went to bed. I decided to give this a try since it had great words from you Sir Isaac. By the way, the first night I took it, it was a wonderful surprise. I haven’t had success with these types of pills before! Well, I took it the break before I left and I was NOT hungry and because I didn’t feel starved half to death. I was able to drive right past jack in the box and go straight home crawled in bed and had no issue falling asleep like I normally do! Holy! I feel like this is going to be the extra push I need to stick to my diet plan. Even when I woke up 6 hours after falling asleep, I still wasn’t hungry even though I’d normally want to rummage through my food for a snack. The desire just wasn’t there anymore and it was a really nice feeling. I am going to report back in the future to see if it added an extra boost in reducing these unwanted fat because it certainly helps everywhere else. It’s the first pill that seems to do just as I want it. Thank you.

  • I have only used this product twice when I first read it here in Isaac’s, but they don’t stink like most pills. It’s also a 2-month supply. I have noticed my late night snacking has decreased. I usually take a prescription sleep aid that I will be taking with it tonight. I was hoping I would be able to substitute the product for my prescription. I will have to find out if it does help me in this matter. With all the positive thoughts from you Sir Robertson, I am excited about the results.

  • I have been using these pills for about a month now since I found it out here, and I have to say I have never been satisfied with the results before from using a product! Due to my work schedule, I have to do my strenuous physical activities in the evening, which would often “work me up” and make it hard for me to go to bed. These pills help me relax and help me sleep better; not to mention, the extra boost to my metabolism does help. Since I have started using these pills in early this year, along with making sure to eat my veggies every day and exercise moderately, I have lost almost 15 pounds. Will definitely be buying these again once I ran out of stocks. Keep informing us Isaac.

  • I have been a loyal reader of Sir Isaac and whenever I want to go through a change in my life, I often seek his posts for advice. Now, I bought this product because again, I want to change my life. Before, I was unable to fall asleep and stay asleep, lose weight and feel rested. After taking this product the first night, it didn’t make me feel tired. So I thought it’s not going to work, but the next thing I know, my alarm was going off. I actually slept the entire night! Amazing!! I don’t wake up feeling groggy or tired like other products I have used before! No restlessness and I’m sleeping every night like a baby! This will now be a part of my night regime from now on. I will be getting this again soon. I am still your fan Isaac. Thanks!
