RSP Nutrition QuadraLean Review

This product claims to focus on combating four major elements of weight loss: energy, appetite, metabolism and fat storage. It also boasts that it successfully does this without the help of any stimulants, which should result in an absence of caffeine-related side effects. The company behind QuadraLean is called RSP Nutrition, which mainly produces merchandise aimed at athletes and gym-goers. Consequently, it may be better suited to providing weight management for this type of lifestyle, but the ingredients seem to suggest that they could potentially help anyone in need of weight assistance.

RSP Nutrition QuadraLean Claimed weight loss benefits

QuadraLean seems to pride itself on its ability to tackle a range of areas contributing to weight management rather than overloading on stimulants which can cause adverse side effects. It can supposedly reduce fat cells, increase metabolism and suppress the appetite to aid weight loss, while also acting as a mood enhancer and converting fat into energy for exercise. Its ingredients are often sold as dietary aids themselves, such as garcinia cambogia and raspberry ketones, due to their alleged ability to help weight loss.

How RSP Nutrition QuadraLean Works

Woman With Pills 538
The method of QuadraLean appears to be utilising each ingredient to specifically challenge a distinct area of weight management. Its conjugated linoleic acid (CLA) ingredient supposedly bolsters the breaking down of fat and reduction of fat cells, while l-carnitine may help to increase metabolism and change fat into energy. The raspberry ketones element supposedly acts to hinder the absorption of fat and support thermogenesis, whereas the final active ingredient, Garcinia cambogia, allegedly suppresses the appetite and boosts mood levels. Since there are no studies into the success of QuadraLean as a complete product, it’s necessary to examine how each ingredient works independently.

Conjugated Linoleic Acid (Clarinol)

Supposedly, the CLA element in QuadraLean mainly works by lowering the amount of fat cells, improving the immmune system and aiding the break down of fatty deposits. It’s also theorised that CLA can decrease the function lipogenesis, while simultaneously boosting lipolysis and fat oxidation in the user. All of these would help weight loss, although further tests must be conducted to establish its true potential on the human body.

Garcinia Cambogia

The tropical fruit Garcinia cambogia appears to work as a weight loss aid by impeding the creation of fat in the body and fending off hunger pangs. It allegedly achieves this thanks to the presence of hydroxycitric acid (HCA), which is the fruit’s active ingredient. HCA is the driving force behind the potential weight-loss skill of Garcinia cambogia. It’s found in the skin of the fruit and seems to block the citrate lyase enzyme, which the body uses to create fat, as well as boosting serotonin in the brain which should diminish the user’s appetite. However, these functions remain speculative as there have been no clinical trials into the effects of the ingredient.

Raspberry Ketones

Raspberry ketone is a chemical compound found in red raspberries. It works as a weight loss aid by apparently enhancing metabolism, which in turn elevates lipolysis and the oxidation of fatty acid. The chemical also indicates that it may affect the human hormone adiponectin, which helps break down fatty acid. However, there’s no concrete scientific evidence to support its metabolism-boosting or fat-burning abilities.

L-Carnitine

L-carnitine, or levocarnitine, is a natural element that is used for energy. This amino acid is produced in the body and helps the functioning of the brain and heart and the movement of muscles, which in turn should boost the exercise level of the user. It’s also suggested that l-carnitine can bolster the number of red blood cells, which is evident when it is used during kidney dialysis. A deficiency of l-carnitine does cause a series of health problems for the patient, but there’s little evidence to boost its standing as an exercise enhancer and weight loss aid.

Key Ingredients

Raspberry Ketones
Looking at the contents and manufacturer’s description of the product, it appears that the desired effect of QuadraLean is for its ingredients to each target a distinct weight loss area: fat, energy, appetite and metabolism. Garcinia cambogia and raspberry ketones are popular weight loss supplements in their own right. However, findings from research on all ingredients remain equivocal, despite their commercial popularity, and QuadraLean has not been scientifically tested to examine and establish any abilities or achievements of weight loss.

Conjugated Linoleic Acid (Clarinol)

Conjugated linoleic acid is a blend of chemicals within linoleic acid that is found naturally in meat and dairy products, as well as manufactured in many supplements. Research in support of this fatty acid for its health benefits is growing and it has also been examined for its ability to aid cancer, atherosclerosis and allergy reactions. Studies have indicated that CLA might contribute to reducing fatty deposits and enhancing the immune system, which might be contributing factors of weight loss. However, more research is needed to verify its potential on humans, as most trials suggesting a positive outcome for CLA and weight management were conducted on animals.

Garcinia Cambogia

Traditionally cultivated as a pumpkin-like fruit native to Indonesia, Garcinia cambogia has fast become a popular supplement across the world. It was traditionally used for cooking and medicines, often being used as a flavouring agent but also taken to prevent the production of gas in the body after a meal. The HCA element found in the rind of the fruit has also shown some promise in the weight management industry, although not clinically proven. Aside from its possible weight loss abilities, research has indicated that Garcinia cambogia may help abate a variety of health problems, such as cancer, diabetes and low red blood cell count.

Raspberry Ketones

The raspberry ketones supplement has become the source of much speculation in the media regarding its weight-loss skill, although there haven’t been any definitive trials into it. Raspberry ketones occur in a variety of fruits, such as cranberries and blackberries, but are ingested in their most potent form via an industrial method. It appears as a fragrance or flavour in many food and cosmetic products, but is typically expensive and must be chemically prepared due to the low amount of it occurring naturally. It could be one of the better-tasting weight loss supplements on the market, but its influence on weight has yet to be verified.

L-Carnitine

The highest concentration of the amino compound l-carnitine is found in red meat, but it’s also commonly found in nuts, fruits, cereals and vegetables. In the body, it functions chiefly in the liver and kidneys with a primary aim of attaining and creating usable energy from fatty acids. L-carnitine can be taken in a variety of forms, including powder, capsule and solution, but its effect on athleticism has little scientific backing. It’s evidently a valuable component of treating muscle disorders and the natural occurrence of it implies that it must contribute to some extent, but there is no scientific backing for it as a significant weight management element.

Clinical Studies

clinical_research_538
Often the most helpful way to assess the safety and viability of a new product is through clinical studies. QuadraLean indicates a certain pride of being free of stimulants, which implies it’s a safe product to use. However, the product as a whole hasn’t been subjected to a clinical trial, so this is a difficult suggestion to trust. There are many customer reviews on websites that sell QuadraLean to gain a greater insight into how successful it is. But another way to judge the effectiveness of QuadraLean is to analyse the studies into each of its active ingredients to examine how they work.

Conjugated Linoleic Acid (Clarinol)

This study aimed to examine the effect that CLA may have on body composition and weight loss. The subjects were all overweight or obese and were given either CLA or a placebo supplement for a 12-week period. The results showed that there was a decrease in not only body weight, but also fat percentage and waist-to-hip ratio. However, this reduction was quite small and other studies have shown that CLA isn’t able to maintain body weight after weight loss.

Garcinia Cambogia

This trial included testing an assortment of supplements to examine their weight loss abilities, but each ingredient was analysed individually. The Garcinia cambogia study involved administering either a dose of Garcinia cambogia or a placebo drug to subjects with a BMI of 32 or greater. The results showed very little difference in weight loss between the people who received Garcinia cambogia and those that took a placebo, although some reduction did occur among the Garcinia group. Other studies have also indicated that the ingredient’s effects on weight loss may be slight.

Raspberry Ketones

As stated before, there have been relatively few thorough studies into the benefits of raspberry ketones considering the supplement’s prevalence in the media. However, this study aimed to analyse whether raspberry ketones helped to prevent obesity, as well as affect metabolism, in rodents. Some of the mice were fed various levels of raspberry ketones and a high-fat diet for ten weeks and the others were fed the same high-fat diet for just six weeks, which was then followed by an identical diet plus the raspberry ketones for the subsequent five weeks. The results suggested that the raspberry ketones hindered weight increase that should have resulted from the substantially calorific diet and that this may have been due to their influence of increasing the rodents’ metabolism and lipolysis function. Obviously, this doesn’t prove that a similar outcome would be evident in humans.

L-Carnitine

This study looked at the effectiveness and contribution of l-carnitine on the weight loss of slightly obese females. The study involved 36 women who were then paired with each other depending on body mass index (BMI). Half of each couple received a twice daily, 2g dose of l-carnitine for eight weeks while their partner ingested a placebo. Every subject walked for half an hour per day, four days a week. The results showed that there was no substantial difference in total body or fat mass among any of the participants, although some of those taking the l-carnitine dose suffered nausea or diarrhoea and left the trial. The evidence that eight weeks of l-carnitine did not reduce the women’s weight over those taking the placebo throws doubt on the value of l-carnitine as a weight-loss drug.

RSP Nutrition QuadraLean Side Effects

Woman With Stomach Ache 538
Checking for dangerous side effects is a must when purchasing dietary supplements. QuadraLean has the bonus of being caffeine-free, often a source of many adverse reactions, but there hasn’t been a definitive clinical study to verify any of its negative side effects. However, that doesn’t mean QuadraLean is entirely side-effect-free. These ingredients are relatively safe in the recommended dose, but side effects may still occur depending on the user. Some of the elements making up QuadraLean may merely cause minor discomfort, such as sickness or diarrhoea, but could also harmfully react with other medication so it’s always worth checking before buying.

Conjugated Linoleic Acid (Clarinol)

When CLA is ingested naturally through eating or when taking the recommended dose in QuadraLean, CLA is generally classed as a safe and nutritional fatty acid. However, some studies have shown quite an adverse effect of CLA on blood sugar levels, both on people suffering from diabetes and those who aren’t. Diabetics taking CLA suffered a worsening control of their blood sugar, whereas overweight but non-diabetic subjects showed a lowering level of insulin sensitivity that could create a prediabetic state. Large amounts of CLA also have the potential to cause minor ailments such as diarrhoea, sickness and tiredness, but there isn’t enough in the daily dose of QuaraLean to trigger these side effects.

Garcinia Cambogia

Similar to CLA, Garcinia cambogia is generally a safe substance and shouldn’t cause issue as part of QuadraLean. However, some reports have indicated adverse reactions such as nausea, headaches and gastric discomfort if taken in large amounts and pregnant or lactating mothers should not use it.

Raspberry Ketones

Raspberry ketones are another natural ingredient of QuadraLean, but there are some reported side effects worth considering. Raspberry ketones are quite similar to the stimulant synephrine, which means the user may experience a level of adverse side effects associated with it. These could include jitteriness, rapid heart rate and high blood pressure. There is probably not enough in a dose of QuadraLean to cause these effects, but the fact that there has been no clinical studies into raspberry ketones should warrant some caution.

L-Carnitine

L-carnitine is a naturally-occuring chemical that is invaluable to the functioning of the human body. Taken in large doses, such as 3g per day, can cause vomiting, diarrhoea and stomach cramps, as well as some far rarer side effects. Fortunately this daily-dose is greater than the one recommended in QuadraLean, so should not occur as adverse reactions of taking this supplement.

How To Use

woman_weight_loss_538
There’s no information available on the RSP Nutrition website explaining how QuadraLean should be taken, but the instructions are presented briefly on the packaging. It recommends that the user take three capsules of QuadraLean on an empty stomach twice every day. Users are instructed to not ingest more than six in one day and to consult a healthcare practitioner before amending the recommended daily dose. The final health warning states that the user should also ask a dietician before using QuadraLean if they are pregnant, breast feeding, taking medication or have a health condition. Research has suggested that those suffering from diabetes or heart problems should be particularly cautious.

Who Makes RSP Nutrition QuadraLean

The manufacturer of QuadraLean is an American firm called RSP Nutrition, which is based in Florida. The company mission seems to be boosting physical performance by providing nutritional supplements and it diversifies itself by claiming to concentrate on enhancing athleticism ability rather than creating fat-burning products. RSP makes and sells a range of apparently nutritional supplements, including glutamine and fish oil, as well as sports apparel. It appears to have a revolutionary outlook on the world of exercise and athleticism, stating that its merchandise is designed to complement the individual sport and body type of its customer. RSP even claims that it is the first nutritional company to recognise the progression of training in the past ten years. There doesn’t appear to be any negative comments regarding the company, although there’s no money back guarantee on their products . It also has popular social media pages that include: Facebook, , YouTube and Instagram.

Where To Buy

where_to_buy_538
Buying QuadraLean may be more difficult if the customer’s not based in the US. The buyer must go to the American site to purchase it from
Amazon, which sells at $24.99 (approximately £16.67) for 150 capsules with free shipping for orders over $35. Possibly the best site to buy from is Dolphin Fitness, as it claims to sell QuadraLean for £22.45 and deliver it within 1-2 days for free with its Super Saver Delivery. Its retail price according to the RSP website is $34.97 (£23.32) for 150 capsules and $9.97 (£6.65) for 30, so customers probably get better value for money by ordering from an alternative retailer based in the UK or even paying for the shipping from the US.

Overall Verdict

RSP Nutritional’s QuadraLean targets multiple areas of weight loss and customer reviews regarding the product have been reasonably positive. There are few expected or reported adverse side effects thanks to its absence of stimulants. However, there is an overall lack of clinical or scientific support for QuadraLean and studies into the ingredients don’t show a significant weight reduction. Whilst the company behind the product may be reliable, they do not offer a money-back guarantee, and there is a lack of information on the official website regarding ingredient quantities and the manufacturing process.
