Superfruits are sweeping the food and supplement industry these days. Many products claim they will improve health and even help you lose weight.
Superfruit Slim claims the ultimate weight loss potential by unleashing “the power of 3 of the finest natures Superfruits in one go.”
So do Superfruit Slim’s fat-burning powers really stand out?
Superfruit Slim Ingredients
Superfruit boasts its 3 superfruits—acai berry, African mango, and raspberry ketone—plus other ingredients are the key to its weight loss success. Let’s look closer to see if these ingredients can really do the job:
Acai Berry (1600 mg). This purple Brazilian berry is rich in nutrients and antioxidants that protect the body against heart disease, cancer, and other conditions. But what about weight loss? Well, acai berry’s popularity is more widespread than its research in this area.
Acai berry contains monounsaturated fats, which may keep you feeling full when included in a controlled diet. One study found reductions in cholesterol, fasting glucose, and insulin levels—all markers of obesity—after a 30-day treatment with acai berry.  However, it was only tested on 10 subjects. Actual acai berry weight loss benefits have not been proven.
Superfruit Slim claims to give you 4 times the strength of acai berry than is available in other diet pills. Whether this could actually lead to increased weight loss is anyone’s guess.
African Mango (1200 mg). African mango’s fiber content helps the body slow digestion and better absorb dietary sugar. Although it may control cholesterol, there’s isn’t much proof it will help weight loss.
One study did find African mango seed extract to reduce weight, fat, and waist circumference when taken as 150 mg twice daily.  With 1200 mg, Superfruit Slim is really upping the ante, but it’s a bit of a gamble whether this could aid in additional weight loss.
Raspberry Ketones (200 mg). Ever since they were advertised as a weight loss wonder on the Dr.Oz Show, raspberry ketone products are everywhere. But are they really that effective?
This compound of red raspberries affects adiponectin, a protein that regulates metabolism. Thus, raspberry ketones may assist in breaking down the fat in your cells. Many raspberry ketone products point to a study where raspberry ketone prevented weight gain in rodents fed a high-fat diet.  This study isn’t enough to prove its benefits, as it wasn’t tested on humans.
The recommended dose is about 100 mg per day. Again, Superfruit Slim is banking on the hope that a greater amount will lead to greater weight loss.
Green Tea Extract (500 mg). Another popular weight loss ingredient, green tea extract sits next to the superfruits, hoping to be a fat-burning wonder. Green tea extract has some potential: it’s been shown to reduce body fat, weight, and cholesterol.  While green tea can decrease obesity risks, it’s unlikely to cause significant weight loss for a long period of time. Plus, large amounts may cause liver toxicity.
Guarana seed (75 mg). This seed’s weight loss benefits probably come from its caffeine and similar chemicals, theophylline and theobromine. These chemicals stimulate the nervous system, heart, and muscles, leading to increased energy. However, too much caffeine causes side effects such as nausea and increased heart rate.
L-carnitine (40 mg). This ammonium compound transports fatty acids during fat breakdown. It’s said to contribute to metabolism and improve weight loss, but results may prove different. In one study, people took 2 g L-carnitine twice daily for 8 weeks and saw no significant changes in fat mass or total body mass.  Some even experienced nausea and diarrhea.
1,3,7-Trimethyxanthine (60 mg). This is just the scientific name for good old caffeine. Caffeine is a popular weight loss ingredient because it boosts alertness and may increase metabolism and exercise performance. However, it also may elevate blood sugar, leading to more weight gain.
Superfruit Slim claims it contains less caffeine than half a cup of coffee. I did a little math to see whether they’re right.
A cup of coffee contains about 95 mg of caffeine, so 60 mg almost fits that description. However, they don’t say whether they’ve factored in the caffeine from green tea extract and guarana seed. Supplements with green tea extract could contain up to 20 mg caffeine. Guarana seed contains twice the concentration of caffeine than coffee beans, so Superfruit Slim’s guarana could have about 16 mg caffeine. In that case, Superfruit Slim could have almost double the caffeine the manufacturers claimed.
Caffeine can cause side effects such as rapid heartbeat, nausea, and muscle tremors. However, the amount in Superfruit Slim probably won’t cause these problems, unless you already use a lot of caffeine in your diet.
On the other hand, Superfruit Slim might not contain enough caffeine to actually aid in weight loss. The typical caffeine content in a weight loss supplement is about 200 mg 3 times a day, and Superfruit Slim doesn’t come close.
What We Like About Superfruit Slim
In some ways, Superfruit Slim does stand out as a diet supplement. Here’s what we like about it:
• It uses all natural ingredients. Even if it doesn’t aid in weight loss, it could aid with overall health.
• Side effects are rare.
• Ingredient amounts are disclosed.
• There’s a 30-day money back guarantee. However, you have to pay for the shipping to get the product and to send the product back (unless you’re returning because of their error).
What We Don’t Like About Superfruit Slim
There are also a few things we wish were different about Superfruit Slim:
• It’s expensive. One bottle is $49.95, 2 bottles are $89.95 (with free shipping) and 3 bottles (plus one free) is $129.95. There’s about 30 servings per container, so each container should last you about a month.
• It’s not available anywhere except directly through the company, SuperFruitSlim.com.
• There are no customer reviews, so no way to know if Superfruit Slim actually works.
• It may get you started in a healthy lifestyle, but it probably won’t result in dramatic weight loss.
Superfruit Slim: The Bottom Line
Superfruit Slim doesn’t make the same ridiculous claims other products do. It doesn’t say you will lose 20 pounds in a week or any of that nonsense. But it does say that weight loss will vary, so there’s no way to know whether it will actually make a significant contribution to your weight loss efforts.
Superfruit Slim is a healthy and safe diet pill. If you want a little push on the road to a healthy lifestyle, Superfruit Slim might be that push. But it’s an expensive push, and it’s not guaranteed to give you amazing weight loss results.
