Rating
Dosing is incredibly important when choosing a weight loss supplement; too much of an ingredient, and side effects are much more likely, but if the dosage is too small, then the supplement offers little or no benefit.

Below we take an in-depth look at Rockstar Carb Block, to see what benefits it offers consumers.

Rockstar Carb Block Overview

What You Need To Know About Rockstar Carb Block

Rockstar Carb Block contains White Kidney Bean (as well as a long list of other active ingredients), but the ingredient quantities used are too small to actually work as a carb blocker. One capsule of Carb Block contains 0.5% of an effective daily dosage. Rockstar Carb Block is incredibly unlikely to actually aid any weight loss.

What Are The Side Effects Of Rockstar Carb Block?

There are numerous ingredients in Rockstar Carb Block that could theoretically cause a range of side effects. The ingredient quantities used appear to all be very small, which does reduce the chances of side effects occurring. However, side effects are still possible, especially if the consumer is sensitive to individual ingredients. There is an unknown amount of caffeine in this supplement.

How Much Does Rockstar Carb Block Cost?

A bottle of Rockstar Carb Block costs $29.95 plus delivery charges. It is available from both the manufacturer’s official website and from Amazon.

Our Verdict On Rockstar Carb Block

Rockstar Sports Nutrition, who manufactures this supplement, are a despicable company who routinely mislead customers and follow poor business practices in order to get sales. We have already exposed how the company offers free bottles for positive reviews, which goes against Amazon’s review policies. The company also makes incorrect and misleading claims about their supplements and their effectiveness.

Carb Block will not aid weight loss, and is a sub-par product with inexcusably small ingredient quantities. Rockstar have tried to hide these incredibly tiny ingredient quantities by using different units of measurement, as well as using a proprietary formula. The proprietary formula is also used to disguise that Rockstar Carb Block is identical to a number of other products in the Rockstar range, including Rockstar Booty Blast, Rockstar W7, and Rockstar Skinny Cleanse. The product is not covered by a money-back guarantee.

Overall, we do not recommend Rockstar Carb Block to our readers.

Rockstar Carb Block Concerns:

  • No money-back guarantee
  • Unlikely to aid weight loss
  • Ingredient quantities are incredibly small

What Does Rockstar Carb Block Claim To Do?

The manufacturers of Rockstar Carb Blocker describe the supplement as a carb blocker, appetite suppressant, and fat burner. They also state that the product works to “detox and cleanse” the body.

Does Rockstar Carb Block Work?

The ingredient quantities used in Rockstar Carb Blocker are ridiculously small. Rockstar have even listed ingredient quantities as micrograms rather than milligrams to make the quantities look much bigger at first glance, and have hidden the rest of their embarrassingly low ingredient quantities behind a proprietary formula. None of the active ingredients that could block carbs are provided in any quantities that could actually be effective; successful studies used 2000mg white kidney bean per day, whilst one capsule of Carb Block contains just 10mg of white kidney bean!

Rockstar Carb Block is incredibly unlikely to aid weight loss, block carbs, suppress the appetite, or increase fat burn, thanks to the inadequate ingredient quantities used in the product.

What Are The Ingredients of Rockstar Carb Block?

The ingredients found in Rockstar Carb Block are detailed below. Some individual ingredient quantities are provided, but the product also features a proprietary formula. The ingredient quantities are given in micrograms instead of milligrams, which makes them seem like larger doses than they actually are. Ingredient quantities listed are per single capsule.

  • Garcinia (Garcinia Cambogia) (Fruit) 40,000mcg (40mg): Test tube and animal research suggest that HCA, the active compound in Garcinia Cambogia, may be helpful in weight loss because of its effects on metabolism. However, numerous studies in humans have found it has no effect upon either appetite or metabolic rate. Source
  • African Mango (Irvingia gabonensis) (seed) 25,000mcg (25mg): One specific extract of African mango, IGOB131, may suppress the appetite and aid with weight loss, according to preliminary trials. However, it is unclear whether or not this extract is used in this supplement. Source
  • Conjugated Linoleic Acid (from Safflower oil) 15,000mcg (15mg): Conjugated Linoleic Acid may help to reduce body fat, but may not cause changes to body weight. Human studies of CLA have produced contradictory results, and it is described as not only a relatively poor fat burner, but also an unreliable one. Source
  • Apple Cider Vinegar 10,000mcg (10mg): Preliminary studies suggest that drinking apple cider vinegar could work as an appetite suppressant, but weight loss results are minimal. It is unclear how a dried supplement version of this ingredient would affect weight loss and appetite.
  • Rhodiola (Root) 10,000mcg (10mg): Rhodiola Rosea appears to improve endurance (as proven in rats), but it also appears to help stave off fatigue. It is not proven to work as a nootropic in non-fatigued consumers, but it does appear to provide limited cognitive benefits to consumers who are fatigued. Source
  • White Kidney (Phaseolus vulgaris) (bean) 10,000mcg (10mg): One study in humans showed that participants who consumed 2000mg of white kidney bean extract a day lost more weight than a control group. This is due to the ability of white kidney bean to reduce the absorption of complex carbohydrates, meaning that it can effectively reduce the calorific content of starchy foods (but not simple sugars!). A serving of Rockstar Carb Block contains just 0.5% of an effective dosage of white kidney bean. Source
  • 5-HTP (5-hydroxytryptophan) (griffonia simplicifolia) 10,000mcg (10mg): 5HTP is used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5HTP reduces the appetite, as well as boosting mood. Source
  • Papaya (leaf) 5,000mcg (5mg): May contain papain, an enzyme that can break down protein and may aid digestion. However, Papaya leaf could act as an appetite stimulant. Source

Proprietary Blend 200 mg

  • Caffeine Anhydrous: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies are small, and some studies are inconclusive. Source
  • Raspberry Ketones: Whilst there is a small amount of evidence that raspberry ketones can cause weight loss in rats, there have never been any human trials on the potential weight loss effects of raspberry ketone. Source
  • Green Coffee (Coffee Arabica) (bean): Whilst it was thought that Green Coffee Bean was a significant aid to weight loss due to its chlorogenic acid content, the relevant research has been discredited as it was fraudulent. Currently, there is no evidence that it aids with weight loss more than any other source of caffeine. Source
  • Hoodia (Hoodia Gordonii) Aerial Parts: This plant extract was eaten traditionally in the South African bush to stave off hunger. There is little clinical evidence to actually prove that it works as an appetite suppressant, and far more studies that show that the product is ineffective and unsafe, frequently causing a wide range of side effects. Source
  • Cayenne Pepper (Capsicum Annuum) (fruit): Capsaicin, found in Cayenne pepper, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts. Source
  • Guarana (Paullinia cupana) (seed): A berry that is naturally high in caffeine, it is often an ingredient in energy drinks and diet pills. Studies are mixed as to whether guarana improves mental performance. Source
  • Turmeric (curcuma longa. L.) (rhizome): Turmeric contains Curcumin, which is thought to have numerous benefits, including soothing an upset stomach and reducing inflammation. However, a recent review of Turmeric studies found that its benefits have been greatly overhyped by the media. No double-blinded, placebo-controlled clinical trial of curcumin has been successful. Source
  • L-Arginine HCl: Important for wound healing and circulation, l-arginine is thought to boost the levels of Nitric Oxide in the body. In this form, it has poor absorption rates. Source

Does Rockstar Carb Block Have Any Side Effects?

There are lots of ingredients in this supplement that could theoretically cause a range of side effects. The ingredient quantities used appear to all be very small, which does reduce the chances of side effects occurring. However, side effects are still possible, especially if the consumer is sensitive to individual ingredients.

White Kidney Bean could cause digestive upset, diarrhoea, changes in bowel movements, flatulence, stomach pain, and bloating.

In one study into Hoodia, participants reported a high number of side effects, which included headaches, nausea, vomiting, ‘odd skin sensations’, increased blood pressure and increases in heart rate. There were also signs of liver damage in some of the participants.

Garcinia Cambogia can cause some side effects including nausea, digestive tract discomfort, and headache.

African Mango may cause increased flatulence and headaches. CLA can cause stomach upset, diarrhoea, nausea, and fatigue. CLA can also increase triglyceride levels in some cases, sometimes sharply.

Apple cider vinegar can affect blood sugar levels. Diabetics should consult their doctor before taking any supplement containing apple cider vinegar.

Consuming large quantities of caffeine can lead to headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness, and insomnia.

Arginine supplementation can cause some side effects such as abdominal pain, bloating, diarrhoea, gout, blood abnormalities, allergies, airway inflammation, worsening of asthma, and low blood pressure.
