I paused before I hit the “publish” button on this Hydroxycut review, because my conclusion was a bit of a shocker. Our in-depth review examined Hydroxycut side effects, ingredients, clinical studies and level of customer service. Additionally, we took a close look at hundreds of customer comments from around the web. Then, we summarized the facts and details to give you the information you need.
What is Hydroxycut?
To begin with, Hydroxycut is a fat burner, or thermogenic, for men and women. The ingredients are robusta coffee , papaya, blackberry, saffron, caffeine, maqui and amla. This one is taken once or twice daily. It’s claimed to boost metabolism and endurance , increase energy levels  and assist with weight-loss . These claims are common in the diet industry, but we’re happy to say there’s some substance to them this time.
Hydroxycut is owned by Canada-based supplement manufacturer Iovate Health Sciences Inc. The supplements are sold at local retailers and through the official website. There are some natural ingredients used, though it’s still a good idea for them to be tested for purity  and it’s nice to see that some positive customer testimonials are available, but read on…
People are desperate to find something to help them lose weight, I know I am, but is this really worth it?
Hydroxycut Ingredients – “Causing Side Effects?”
The first issue with Hydroxycut ingredients was the connection to side effects . “Science has done an amazing job researching stimulants, which are extremely popular , and natural ingredients commonly used in the supplement industry,” offers our Research Editor. “Sometimes the term “natural” is taken as being synonymous for “risk-free.” Sorry to disappoint, but evidence shows otherwise, if only in a small portion of the population.”
One customer who experienced Hydroxycut side effects said, “This product made me sick to my stomach. I felt tired. As soon as I stopped taking this I felt back to normal.”
Another stated, “Made me feel sick, I didn’t see any results after taking the whole bottle.”
We wanted to see a more well-rounded picture, so we found Hydroxycut reviews that didn’t mention adverse reactions.
One stated, “The scale has gone down a little since starting the pills and I haven’t experienced any side effects.”
Scroll below for one of the best products we’ve seen over the last year.
Ineffectiveness – “Are People Losing Weight?”
According to some Hydroxycut reviews, the lack of results was concerning. This is where science and years of research come to mind. There is no one supplement out there that will work for everyone. Anyone wishing to try a formula like this must know that going in.
“This product does not work. I worked my butt off and didn’t lose any weight and it did nothing,” commented a dieter.
“I haven’t lost any weight…eat healthy and exercise about 5 times a week,” stated a consumer.
There are reviews on both sides of the debate.
“On day 5 of taking this pill and have seen an increase in my energy level a decrease in my appetite,” said a customer.
“It is now about 11 days later. I have little to no side effects, but it really depends on the person,” reported another.
Our research into Hydroxycut ingredients has revealed that science and customer reviews are an important contributing factor in terms of your chances of long-term success. With Hydroxycut, there are people who’ve successfully lost weight and there are those who didn’t. Peer-reviewed journals have completed double-blind studies  on some of the ingredients used in this formula and, just like reviews, there are positive and negative results.
The Science – “Any Studies?”
Hydroxycut emphasizes the effectiveness of their diet products on the company website. There’s even clinical research using humans  . What we found was that the studies involved a small number of participants and provided mixed results, which appears to be the case across all studies, according to a “systematic review and meta-analysis of randomised clinical trials” on green coffee bean extract . The ingredient list does contain caffeine, but the benefits aren’t unique to this formula. We at DietSpotlight look for solid-science to use throughout the review process. There’s a concern when there’s nothing to stand on or when the company doesn’t bother to offer strong support from multiple peer-reviewed studies.

The Bottom Line – Does Hydroxycut Work?
Alright, why don’t we clear away the dust to reveal exactly what this one is about? We certainly appreciate that Hydroxycut has been around for more than a decade and that it contains a few natural ingredients. However, we don’t feel comfortable giving this one a thumbs up because these diet pills lack the support of clinical research. Plus, we’re concerned about customer complaints regarding negative side effects and poor results.
If you’re really interested in shedding more pounds, we suggest going with a supplement that’s backed by real scientific research and not connected to harmful side effects.
Among the best products we’ve seen in 2016 is one called Leptigen. The four clinically-tested ingredients have been shown to help boost metabolism and speed up fat loss. We can’t locate any negative discussions of harmful side effects and dieter comments we found are seeing that people are seeing amazing results.
Also, the company behind Leptigen is so confident in their supplement, they’re offering a Special Trial Offer.

Needless to say, there are a vast number of options at your disposal these days when it comes to diet medications and weight loss programs. While Hydroxycut is by no means the most difficult to acquire, it doesn't necessarily stand out as the be-all end-all to weight loss. Their FDA warning
is, however, uninspiring. If you'd prefer a diet plan that involves the simplicity of a pill taken two to three times daily, Hydroxycut may be an option to consider. However, it's imperative to keep in mind that there are countless other supplements, medications and plans to consider, many of which can be attained without a prescription.

“When I first began this regimen I was over anxious and skipped the “trial period” where you only take one pill and build up to the suggested serving size, so I started taking the full amount immediately and experienced some restlessness and my heart fluttering like I was anxious. I backed off and this went away.” Kenneth

Hydroxycut Scientific Abstracts:
Robusta Coffee Extract
Clinical trials have examined the effects of Robusta coffee extract (green tea extract) on weight-loss and all of them have been in poor quality. There had been a conducted meta-analysis of three studies where overweight volunteers received 180 or 200 mg/day GCE for 4 to 12 weeks. It had been concluded that GCE has a moderate but substantial effect on body weight (MWL of 2.47 kg greater than placebo). 
In controlled trials a large effect size was discovered for saffron supplementation versus placebo in treatment for depressive symptoms (M ES = 1.62, P < 0.001). This has revealed that saffron had significantly lowered depression symptoms when in comparison to the placebo. There wasn’t much of a difference between saffron supplementation and antidepressant groups (M ES = -0.15) which led researchers to believe that both treatments were similar in the reduction of depression symptoms. It is believed that larger trials with long-term follow-ups are required before any concrete conclusions can be made on the treatment for depressive symptoms. 
Trials conducted on 54 resistance-trained males who completed strength testing of 1RM (one-rep max) and RTF (repetitions to fatigue) at 80% of one-rep max for leg press and bench press. Volunteers then finished five 10-second cycle ergometer sprints with a minute of rest between. After 48 hours, participants had ingested a beverage with caffeine anhydrous (300mg; yielding 3 to 5 mg/kg bodyweight), acute coffee (8.9 g; 303 mg caffeine), or the placebo (PLA; 3.8 g). Leg press one-rep max had improved more by acute coffee than caffeine anhydrous (p = .04), but not placebo (p = .99). Bench press 1RM, bench press RTF, or leg press RTF significant interaction (p > .05) had not been observed. Neither the acute coffee nor the caffeine anhydrous improved strength more than the placebo. It was concluded that coffee and caffeine anhydrous may be a suitable pre-exercise sources of caffeine for high-intensity work outs. 
Preclinical studies have exhibited that amla extract contains analgesic, antipyretic, antiatherogenic, antitussive, gastroprotective, cardioprotective, adaptogenic, antianemia, wound healing, antihypercholesterolemia, antiatherosclerotic, antidiarrheal, nephroprotective, hepatoprotective, and neuroprotective properties. Experimental studies have also pointed out that amla and some of its phytochemicals also harness possess antineoplastic effects. In additional reports, amla was said to contain chemomodulatory, radiomodulatory, anti-inflammatory, chemopreventive effects, antioxidant, free radical scavenging, antimutagenic and immunomodulatory activities, which are properties that are effective in treating and in the prevention of cancer. 
Hydroxycut is one of the more popular names in the weight-loss industry. The original (Pro-Clinical) formula contains quite the caffeine punch, but it's not the strongest stimulant in the line.

We dug deep into the Hydroxycut ingredients to give you the details you need.
Caffeine is a central nervous system (CNS) stimulant found in coffee, tea, soda, and energy drinks. It’s also included in a number of weight-loss supplements, and is available in pill form without other ingredients.
What is it Supposed to Do?
According to WebMD, caffeine is most often used to improve mental alertness, but has other uses, as well. In the case of weight-loss supplements, it can be used in very high doses to replace illegal stimulants.
According to Medline Plus, caffeine “can make you more alert and give you a boost of energy.” 
Cayenne pepper is a red pepper, or a chili pepper. It is commonly used in cuisine to add heat and flavor to dishes.
What is it Supposed to Do?
According to WebMD, cayenne pepper “may help burn calories and curb appetite, especially in people who aren’t used to eating it.”
According to a study published in Physiology & Behavior, “The appetite responses were different between those who liked red pepper and those who did not, suggesting that when the stimulus is unfamiliar it has a greater effect.” Study results indicate that once a person becomes used to spicy food, the effect wears off, but further study is needed to determine when the effect stops working. The study showed those who ate a half a teaspoon of the pepper either before or mixed with their meal burned 10 more calories over a four hour period than those who did not, so the results are small.
Yombimbe is a tree native to Nigeria, Cameroon, and the Congo. Its bark is used for medicinal purposes. The tree may be endangered as a result of overharvesting.
What is it Supposed to Do?
According to the University of Michigan, it is supposed to help weight-loss by boosting metabolism, suppressing the appetite, and increasing fat burning through stimulation of the nervous system.
Research on yohimbe and weight-loss is limited. However, a systematic review of multiple supplements published in the American Journal of Clinical Nutrition revealed that yohimbe, along with various other supplements marketed to dieters don’t have convincing data to support them. “None of the reviewed dietary supplements can be recommended for over-the-counter use.”  Other supplements included in this review were garcinia cambogia, yerba mate, pyruvate, and glucomannan.
L-Theanine, also known as theanine, is an amino acid [a building block of protein] found in green tea. Its chemical structure is similar to glutamate, a naturally occurring amino acid that helps the body transmit nerve impulses to the brain.
What is it Supposed to Do?
Theanine had been used for treating “anxiety, high blood pressure, for preventing Alzhimer’s disease, and for making cancer drugs more effective.” That’s not to say science supports these claims.
According to the U.S. National Library of Medicine, theanine may be effective for treating some metabolic disorders (genetic in nature). There’s no strong connection to weight-loss or athletic performance.
You don’t need a ton of ingredients to effectively boost metabolism or cut appetite. Take Leptigen into consideration. There are just four ingredients and science is there to support them all.
