I had 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, and clinical studies. 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 or green coffee bean , papaya, blackberry, saffron, caffeine, maqui, and amla. This one is taken once or twice daily. It claims 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…
Hydroxycut Ingredients – “Side Effects, Not Really!”
The first issue with Hydroxycut ingredients was the connection to mild side effects . “Science has done an incredible job researching stimulants, which are hugely popular, and natural ingredients commonly used in the supplement industry,” said our Research Editor.
One customer who experienced Hydroxycut side effects said, “I had a slight headache. Took one less per day and it went away.” 
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.”
Effectiveness – “People are Losing Weight”
According to some Hydroxycut reviews, the lack of results was concerning. But, we found that some users didn’t follow the recommendations of the company relating to proper use.
“Didn’t lose any weight, but I’ve only been taking it for a week,” commented a dieter. 
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 who noticed Hydroxycut results. 
“It is now about 11 days later. I have no side effects, and I’ve started to fit better into my clothes,” reported another.
Our research into Hydroxycut ingredients has revealed that science and customer reviews are an important contributing factor regarding your chances of long-term success. With Hydroxycut, there are people who’ve successfully lost weight and have seen substantial results. Peer-reviewed journals have completed double-blind studies  on some of the ingredients used in this formula and, just like reviews, there are positives out there.
The Science – “We Found the Research”
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, which has been shown to boost metabolic rate. We at DietSpotlight look for solid science to use throughout the review process. We’re pleased to see that Hydroxycut decided to put the evidence out there for dieters.Also: read our Leptigen Weight-Loss Kit review »
The Bottom Line – How Does Hydroxycut Work?
We did the research, so what are our final thoughts on Hydroxycut results? We certainly appreciate that the company has been around for more than a decade and that it contains a few natural herbs. There’s also solid science backing key ingredients of the formula. The only issue we’ve found was that some users didn’t follow the directions and expected results, without allowing the supplement time to work. .
If you want to boost your results, we suggest a supplement containing ingredients backed by science and supported by positive customer comments.
Another of the best products we’ve seen this year is our supplement Leptigen. The four ingredients, clinically-tested on humans, with results often found in publications such as The American Journal of Clinical Nutrition.
Also, we have so much confidence in our supplement; we’re offering customers a Special Trial Offer.

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 concluded 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 might be a suitable pre-exercise sources of caffeine for high-intensity workouts. 
Preclinical studies have exhibited that amla extract contains analgesic, antipyretic, antiatherogenic, antitussive, gastroprotective, cardioprotective, adaptogenic, antianemia, wound healing, antihypercholesterolemic, 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 useful in treating and in the prevention of cancer.

Hydroxycut Side Effects:
These days, supplements play an increasingly important role in everyday life. Just because something is natural, it doesn’t mean they go hand in hand with your experience being side effect-free. Side effects of Hydroxycut are typically rare, that doesn’t necessarily mean they don’t occur with certain individuals.
Showing signs of weariness or concern. Nervousness is the fear of an impending negative situation, or a sensation of anxiety, panic, or dread.
What causes nervousness?
Nervousness can be brought on by obsessive thinking, stressful environments, or caffeine consumption. It may be a genetic chemical imbalance or triggered by certain medications.
Dizziness is the sensation of feeling faint, woozy, or unsteady. Typically categorized as vertigo, it’s the feeling that your surroundings are in motion when in a stationary position.
What causes dizziness?
Dizziness can be triggered by a common cold or more serious conditions such as inner ear infection. In some cases, dizziness is caused by stress or anxiety, poor eating habits, and lack of sleep. You may also experience dizziness as a direct result of vertigo. The imbalance of inner ear fluids make your surroundings appear to spin uncontrollably.
The shakes occur when muscles in your body tremble out of your control. They can range from mild to severe, typically affecting the arms, legs, and hands.
What causes the shakes?
There are a number of possible causes for the shakes, including caffeine, low blood sugar, or stress. There can be also psychological factors such as anxiety. Neurological disorders or certain medications can cause limbs to involuntarily shake and tremble.
When your heart reaches 100 beats per minute (BPM) or more it’s considered tachycardia. Once your heart reaches these elevated levels, it’s difficult to pump oxygen-rich blood to your body.
What causes rapid heartbeat?
Rapid heartbeat (tachycardia) is caused by a disturbance of electrical impulses which control the pumping action of your heart.  These can be brought on by a number of factors including, excessive exercise, poor eating habits, high blood pressure, or smoking.
Canker sores (aphthous ulcers) are small, shallow ulcers that form in the mouth and lips.
What causes canker sores?
Canker sores can be triggered by any number of factors including stress, viral infection, hormonal fluctuations, or mineral deficiencies. Food sensitivity to chocolate, some fruits and nuts, coffee, or even toothpastes can cause a canker sore.
Side effects of Hydroxycut are uncommon, but there have been a few cases where individuals were negatively affected. There have been few reports of canker sores, dizziness, rapid heartbeat and more. In an effort to shield yourself from any future issues, you may want to speak with a physician before taking any supplements, specifically if you are under the age of 18, currently taking prescription medications, have a medical condition, or are pregnant or nursing.
Hydroxycut is a fat burner from a company that’s been in the business for quite a while. It contains a stimulant in high enough quantities to cause some side effects, but only in rare cases.
“I took them only one day and only noticed a headache.” Salena
“A little stomach ache, but I also didn’t eat before taking it.” Renia
“Side effects were mild, like increased heart rate. My fault for drinking too much coffee.” Anya
“I started yesterday taking the recommended dosage I took 3 yesterday. A bit too much (heart rate increased), so I cut it back some.” Sarah
“My first day consisted of light headedness. Hubby tole be to eat and drink water and I didn’t.” Kasey
“By the time I got up to taking 2 caplets three times a day, I started getting headaches.” Michelle
“It made me feel sick to my stomach. Should have followed the directions and eaten food.” Jen
Our experience has led us to believe one thing – side effects of Hydroxycut should never be something you settle for. Products like Leptigen, one of the many we’ve reviewed over the years, proves you can have effective without a long list of side effects.
Hydroxy cut 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 Hydroxicut ingredients to give you the details you need. We want you to know – does Hydroxycut really work?
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.
