Below we take an in-depth look at Core Nutritionals Burn to see whether it can aid weight loss through increased thermogenesis in the body, as claimed by the manufacturer.
Burn is a thermogenic weight loss aid manufactured by Core Nutritionals.
They also have a similarly named fat burning supplement called Burn Ultra; these are different supplements, and it is important not to confuse the two.
Core Nutritionals are based in the USA, but they do not provide their address on their official website or social media pages. The company has a ‘contact’ button, which opens up the mail live program on windows but does not provide any contact details. The company can also be contacted through their facebook page.
Their website states that ‘all Core Nutritional products are manufactured in the U.S. and in cGMP facilities.’ Core Nutritionals have been previously instructed by the FDA to stop selling one of their supplements containing AMP Citrate, as the product was incorrectly marketed as a dietary supplement despite it not being a natural ingredient.
To assess tolerance, start by taking 2 capsules with food in the morning. An additional 2 capsules can be taken with food 5-6 hours later. Once tolerance is assessed, serving can be increased to 3 capsules in the morning and 3 capsules 5-6 hours later. Do not exceed 6 capsules in a 24 hour period. Do not use longer than 8 continuous weeks without a four week break. Do not take with other products or foods containing caffeine or other stimulants.
The manufacturers of Core Nutritionals Burn describe the product as an ‘Innovative multi-stage thermogenic’ weight loss supplement.
Core BURN is formulated to drop the kitchen sink and “miracle” ingredient tactics, and instead uses a diverse range of proven ingredients to create a powerful, balanced, and effective product. Core BURN is designed to target precise primary and secondary metabolic pathways, at multiple targets, to ensure maximum effectiveness. No more playing darts in the dark when it comes to weight management categories; randomly including ingredients, in whatever servings, hoping that something works. Specific.Multi-targeted. These words exemplify the new approach: amazing ingredients, in clinically-reflected serving sizes, all included in a non-proprietary blend so you know exactly what you’re consuming.
The ingredients used in Core Nutritionals Burn are listed below. The ingredient quantities listed are per serving of three capsules. Consumers can take up to two servings per day for a total maximum of six capsules.
Yohimbe and bitter orange extracts have been associated with a wide variety of side effects, as described in the side effects section below, which could prevent some groups of people from taking this diet pill.
Caffeine and synephrine are both proven weight loss aids, although, as mentioned above, some have better safety profiles than others. Caffeine’s effects upon the metabolism are thought of as small but significant. Theobromine is a stimulant that is similar to caffeine in structure, but it is even weaker, and unlikely to make a noticeable difference to the metabolism.
Green tea contains catechins which could increase thermogenesis in the body. Again, whilst this could contribute to an increased rate of weight loss, its overall effect is relatively small.
Green coffee bean currently has no strong clinical support from trials as the main trial that was most often referenced was retracted after it was discovered that it was fraudulent.
Bacopa Monnieri needs to be taken daily for an effect to build up over time, and may reduce anxiety and improve memory.
Coleus Forskohlii does not appear to affect overall weight loss, but it may affect body composition. Acetyl-L-Carnitine is often touted as a fat burner, but this effect has only been seen in the elderly in clinical trials. For the rest of the population, L-Carnitine may help boost energy levels, combat fatigue, and will work as a source of amino acids for consumers who are trying to build muscle mass through appropriate exercises.
There is a long list of ingredients that are used in Core Nutritionals Burn, and many of them are present in high doses. This means that there is a long list of potential side effects that could develop whilst taking this product. It is very important that consumers test their tolerance for the product when they first take it, and that they cycle use of the product as instructed.
Side effects associated with the use of Bitter Orange extract include increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo Clinic has recommended avoiding use of Bitter Orange extract because in their opinion, the risk of using the product is not worth the pay-off of any potential weight loss. The effects of synephrine and other bitter orange extracts are enhanced when combined with caffeine.
Green tea and green coffee bean are both potentially sources of naturally occurring caffeine, depending upon whether or not caffeine free extracts are used in this supplement. There is also an amino acid in Green Coffee Bean called homocysteine that is associated with an increased risk of heart disease. Green tea can cause constipation.
Side effects of caffeine can include headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness and insomnia. The maximum daily dose of this supplement (six capsules) contains a total of 500 mg of caffeine, which is incredibly high, making it much more likely that side effects will develop. Avoid all other sources of caffeine completely while taking this product!
Yohimbe can cause a wide range of side effects, including stomach upset, excitation, tremor, sleep problems, anxiety or agitation, high blood pressure, a racing heartbeat, dizziness, stomach problems, drooling, sinus pain, irritability, headache, frequent urination, bloating, rash, nausea, and vomiting. High doses can cause more severe effects.
Studies have shown that Bacopa leaf causes upset stomachs in participants much more than placebos. This has led to the recommendation that this ingredient be taken with a meal, rather than on an empty stomach, as this will minimise the chances of getting an upset stomach. It may also cause nausea, cramping, bloating, and diarrhoea.

Although the product is no longer stocked by bodybuilding.com, the customer reviews that were left by consumers are still available to read on the website. There are also numerous customer reviews on the Tiger Fitness sales page for Core Nutritionals Burn.
This definitely seemed to have more of a punch to it than other thermogenics I’ve tried, but I didn’t see any weight loss. But then again, I only had sample packs that I took for four days, I believe. Maybe it’ll work better for you. All I got was slight jitters after about an hour and a half.
Unlike other fat burners, I didn’t find myself to flush with this product but I did have the occasional burps that tasted of raspberry. I feel as though the caffeine gave me an energy boost and kept me going throughout the day.
Excellent product! I’m two weeks into it and already seeing great results while stacked with yohimbine. I’m looking much tighter and fuller as I shred down. I can notice that I sweat more while taking the product, but I have no jitters whatsoever. I’d definitely recommend it.
Core burn is fantastic! Clean energy and great overall sense of well being while taking this product. Full ingredient disclose from a company you can trust, what more could you ask for? Core burn from core nutritionals is a must for those looking to break that plateau while dieting!
Excellent product!Burning fat without any crazy jitters. I’m currently on my second bottle and it is definitely effective!
With a nice clean roll in and results i can see over the first two weeks of use, I highly recommend this product. There’s no crazy jitters or shakes here, just a warming sensation with a slight increase in sweat generation. I’ve been able to peal off 2% body fat while increasing body water percentage and muscle density over the past two weeks of using this product in conjunction with a 3.5 day 1500 caloric restriction, re-feed meal and moderate carb backloading immediately post workout. Body weight has gone down from 278 to 267 so far and I am now within 17lbs of my 2014 goal! I’m planning to go through another cycle of this product after my 4 week off period.
This is my second time taking the core burn stack and I absolutely love it. It’s helping me get on the right track to prepare for summer and I have lost about 10 lbs since starting it a little over a month ago. The bottle has lasted almost 2 months and I still have a few days left. This product worked so great, I wish it didn’t have to end and I had more to continue helping towards reaching my ultimate goal!
The customer reviews that we were able to find for Core Nutritionals Burn were overwhelmingly positive, with only one reviewer mentioning any side effects. Some customers love the increased energy levels they feel, using the product as a pre-workout supplement, but do not report back on whether they experienced any fat loss or weight loss. However, others specifically state that they have lost significant amounts of weight and reduced their body fat percentage when using this product in conjunction with regular exercise and a healthy diet plan.
Some of the ingredients used in Core Nutritionals Burn could increase the body’s metabolic rate and contribute to weight loss, provided that the consumer does not experience any unpleasant side effects, which would stop them from using the product (for their own health).
Overall, we suspect that the presence of bitter orange, caffeine, theobromine and green tea will mean that consumers who are already dieting will notice an increased rate of weight loss whilst taking this product.
Core Nutritionals Burn is not available for purchase from the official manufacturer’s website, but they do provide links to many of the online third-party retailers that stock their products.
Tiger Fitness sells a bottle for $44.99 plus delivery charges. However, the sales page states that it contains 120 capsules in one place, but states 150 capsules in another, and so it is unclear exactly how much of the product consumers are paying for.
The bottle states 150 capsules, but the image is small and easy to miss.
As the manufacturer does not sell their product directly to customers, they do not offer any type of money back guarantee on their products.
Tiger Fitness, one of the third party retailers that sells the product, offers a 30-day returns policy, provided customers obtain an RMA number before sending the product, and that the product is in resaleable condition.

To return the item(s), simply e-mail [email protected] or call us at 1-877-397-3801 toll-free to obtain your RMA#. Once you have obtained your RMA# send them in a carefully packed box to:
ATTN: Returns / RMA #
150 Commerce Drive
Loveland, OH 45140
INCLUDE YOUR RMA# ON THE BOX! If you ordered the item more than 30 days ago, you can still return the products for a refund if they are in sell-able condition, but we will charge a 25% re-stocking fee. We can take care of this for you!
If you ordered more than 60 days ago, we can not accept the return.
Core Nutritionals, the company who manufacture Burn amongst other supplements, is run by a married couple who are a ‘drug-free bodybuilder’ and a ‘drug-free natural figure competitor’, and yet the company was cautioned by the FDA in 2015 for selling a product containing a unnatural, lab-synthesised ingredient that is not classified as a dietary supplement.
The product is not available directly from the manufacturers, and so the product comes with no money back guarantee. However, it is available from some reputable online supplement retailers, including Tiger Fitness. It seems that the product has limited availability, with many of the listed retailers on the Core Nutritionals website no longer stocking the product.
The product can cause numerous side effects, thanks to the use of yohimbe and bitter orange, as well as numerous other ingredients. Side effects from yohimbe appear to be common in general, but bodybuilders swear by the ingredients, despite mixed clinical support.
Consumers need to take as many as six capsules per day, and so even though a bottle of 150 capsules sounds huge, it will last for a mere 25 days if using the maximum dose. The product also needs to be cycled regularly.
Overall, we are not convinced that this diet pill is ideal for everyone; the reviews on bodybuilding.com are often written by consumers who are bodybuilders and who use fat burners and pre-workout supplements regularly, and so may have developed a high tolerance for the stimulant ingredients. This product may aid weight loss, but the risk of side effects means that consumers are taking a risk when ordering the product.
Overall, we cannot recommend Core Nutritionals Burn to our readers.
