Cellucor Super HD Xtreme Review

Cellucor Super HD Xtreme is another exciting Cellucor product due to soon be released in New Zealand. This is an updated version of the previous Cellucor Super HD, a popular fat burner which was released here in 2014 but has since been discontinued. While Cellucor have kept some ingredients the same, we think some definite improvements and have been made.

Cellucor is known predominantly for their explosive energy pre-workouts which are some of the most popular pre-workouts on the market. As seen in the soon to be released Cellucor C4 Ultimate Pre-workout, Cellucor are creating products that go beyond just increasing energy, or in this case just burning fat, and creating a new level of supplements that support focus, cognition, and mood too. While Cellucor have kept some ingredients the same in the latest version of Super HD, we think some definite improvements have been made. Check out our Cellucor Super HD Xtreme review to see why we’re hanging out for this product to hit our shelves.


  • Clean sustained energy

  • Supports thermogenesis

  • Supports increased fat metabolism

  • Mood support

  • Appetite suppression

  • Well-dosed ingredients

  • Caffeine Cocrystals for extended caffeine release


  • Proprietary Blend leaves us unsure of exact dosing of some ingredients

  • High Taurine dosage

Cellucor knows to complete a tough workout you need to not only be energized but also alert and focused. They also knows it’s tough when you’re dieting for fat loss and still hitting the gym. This is why they've combined the following ingredients to support fat loss, increase fat metabolism, increase energy and focus, and support mood.

The first three ingredients are all new to Super HD Extreme. The previous version’s main ingredients were Caffeine Anhydrous, L-Tyrosine, Toothed Club Moss, and the Super HD TS Blend (245mg) containing Green Tea Leaf Extract, and other various extracts. Cellucor have reduced the number of extracts and actually increased the Super HD Xtreme Blend to 458mg for more effective dosing of key ingredients.

Taurine (2000mg)

Taurine is a conditionally essential amino which improves performance by enhancing mental focus and cognition. It also plays a role in increasing fat loss by increasing lipid metabolism – the breaking down of stored fats for energy. A study of 30 overweight or obese college students showed that 3g Taurine per day over 7 weeks significantly reduced body weight. It also lowered Triacylglycerol (TG), total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) levels.

One serve provides a hefty dose of Taurine. The recommended daily dosage of Taurine is 500-2000mg which is just one serve of Super HD Xtreme. The bulk of studies and research done suggest a dosage of up to 3g Taurine per day is the safe upper-limit. Taurine excess is excreted by the kidneys. Research shows larger doses have been used with no side effects but there is limited research on the long term effects of this. https://www.ncbi.nlm.nih.gov/pubmed/18325648

Acetyl-L-Carnitine HCl (500mg)

This version of carnitine is used as it provides the best brain boosting effects alongside fat metabolism. Acetyl-L-Carnitine is more bioavailable than standard L-Carnitine as it able to cross over the blood-brain barrier. Benefits include increased memory, mental energy, information processing, learning, and increasing your attention span.

Acetyl-L-Carnitine is also included for its fat metabolising properties. It helps your body metabolize fat by working with your mitochondria to break down stored fat for energy.

The recommended dose of Acetyl-L-Carnitine for weight loss is 500-1500mg which is easily hit with 500mg per serve.

Garcinia cambogia fruit extract (500mg)

Garcinia cambogia is a popular fat loss supplement for its Hydroxycitric Acid (HCA) content, however the research and results are mixed. There appears to be successful studies with animals but researchers have yet to produce the same results in a human trial.

One study showed that treatment with Garcinia cambogia extract (HCA 1000mg) significantly reduced abdominal fat after 12 weeks.

Another study showed that 500mg HCA may increase fat usage during moderate intensity workouts. The study gave 6 men 500mg HCA per day for five days combined with moderate intensity exercise. The results showed an increase in fat oxidisation and sparing of carbohydrates as an energy source.

Taking the suggested two serves per day will give a dose of somewhere between 500mg and 1000mg HCA depending on the standardization of Garcinia Cambogia extract used. This will be enough to gain results when combined with a moderate exercise program.

SuperHD Xtreme Blend (458mg)

Caffeine Anyhdrous (175mg)

Caffeine is most known for its ability to increase energy short term, but it also boosts your metabolism to help you burn more fat. Caffeine is also a powerful thermogenic, increasing thermogenesis for up to 2 hours. According to researchers, at least 100mg of caffeine is needed to boost thermogenesis. This version of super HD has slightly more caffeine than the original (160mg) but not significantly.


As this is listed after Caffeine Anhydrous we know it must contain 175mg or less N-Acetyl-L-Tyrosine (NALT). NALT is the main focus enhancer in most of the c4 preworkouts and is used to improve mental focus by increasing noradrenaline and dopamine. NALT also supports mood and reduces stress. The previous version of Super HD used L-Tyrosine, but Cellucor have removed it in favour of NALT as it is better absorbed by the body.

Rhodiola (Rhodiola rosea) root extract

Also included in the previous version, Rhodiola rosea is an adaptogen that helps prevent the negative effects of stress. It is also used to increase energy, improve cognition, support mood, fight off fatigue, and aid post-workout recovery.

Advantra Z Citrus aurantium fruit extract (standardized for p-synephrine content)

Another ingredient carried over from the previous version - This is the branded version of natural Citrus aurantium (bitter orange) extract. It is a non-stimulant ingredient that may support energy and increase alertness.

Purenergy Caffeine Pterostilbene Cocrystal

PURENERGY® is a co-crystal that combines caffeine and pTeroPure®. According to a recent study, PURENERGY® delivers 30% more caffeine into the bloodstream than ordinary caffeine and extends the half-life of caffeine by nearly 25%. This is what gives Cellucor Super HD Xtreme its smooth sustained clean energy with no drop off crash.

 Nelumbo nucifera seed extract

The Nelumbo nucifera flower is commonly called Indian Lotus or Sacred Lotus – it is used for its Higenamine content. Higenamine is a beta-1 and beta-2 adrenergic receptor agonist (agonist: chemical that binds to receptor). It is used for increased fat burning, increased oxygen utilization, and boosting mental energy. Higenamine is a beta 2-agonist, so while there is a lack of human studies, it does show promise as supplementation with other beta 2-agonists have been reported to promote fat loss and muscle growth.

Capsimax Cayenne (Capsicum annum) fruit extract 50mg

Although included in the previous version, it was part of the Super HD TS Blend (proprietary) so we are unsure what the dose was. Here it is included at 50mg per serve. Capsimax gives you the weight management benefits of red hot peppers without the intense burn. A study has shown that 2mg of capsaicinoids from 100mg Capsimax promotes increase lipid metabolism and fat mobilisation for energy. Two servings per day of Super HD Xtreme will provide 100mg Capsimax. Although designed so you don’t feel an intense burn, you can sometimes feel a mild heat while drinking this supplement.

Overall, Cellucor have done a great job at revamping Super HD and we think it’s going to be a hit this summer. With well-dosed ingredients to support energy, fat metabolism, cognition, and mood, this supplement will help not only with fat loss but also the daily demands of dieting and training.

Those of us who have tried a sneaky preview of this product (combined with a diet and training program) have noticed decreased appetite, increased energy, focus, and mood, and the all important fat loss results. Cellucor Super HD Xtreme will be available in 30 Serves in either Pineapple or Peach Mango. Pineapple is definitely a winner but we're sure Peach Mango will be amazing too. Cellucor always have their flavours on point.

It will be a similar, if not the same, price as Cellucor C4 Ripped.

Keep any eye out for this product at Sportsfuel Supplements online or at one of the Sportsfuel Outlet Stores.
