Death By Raspberry Ketones And Caffeine Powder: The Dangers Of Otc Supplements

Death By Raspberry Ketones And Caffeine Powder: The Dangers Of Otc Supplements

Supplements aren’t always so harmless. (Facebook) Cara Reynolds, 24, took her first dose of Forza raspberry ketone supplements in February 2013 to help with a new weight-loss regimen. She went to her dad soon after with complaints about heart palpitations. “She’d only taken the recommended amount of pills but was scared because her heart was going 10 to the dozen,” her father told The Daily Mail. “That’s when she said she wasn’t going to take them for weight loss any more — it had really worried her.” However, after a split from her fiance the following month, the British healthcare worker took a lethal dose of the supplements she had bought off Amazon for under $40. Doctors tried 44 times to resuscitate Reynolds, but were unable bring her back. Raspberry ketones are the chemical compound that give the fruit its scent, and have been touted by the media and personalities like Dr. Oz and Kim Kardashian as weight-loss wonders. Although a few preliminary studies have shown ketones may help with weight loss, the evidence of its effectiveness is mixed at best. Outside a few animal and test-tube studies, there’s little science that proves ketones really work for slimming down. Along with raspberry ketones, Forza supplements combine resveratrol and caffeine. These tablets contain up to 250 milligrams of caffeine per pill, or roughly the same amount you’d get from four cans of Red Bull or seven cans of Coke. The dose Reynolds consumed was likely the equivalent of 2.5 cans of Red Bull. Through a representative, Forza issued a statement regarding Reynolds, saying, “This is a tragic and understandably upsetting situation for her family and friends, but it could have been effected through the misuse of any supplement. Forza products meet vigorous health and s Continue reading >>

What Is Raspberry Ketone?

What Is Raspberry Ketone?

MORE A raspberry contains 200 molecules that contribute to its distinct raspberry flavor. One of those, raspberry ketone, was singled out by food manufacturers decades ago for its potent smell. Berry-flavored candy, soaps and candles made today likely use raspberry ketone. More recently, the raspberry ketone garnered public attention again, but this time as a purported weight-loss aid. Raspberry ketone is actually found in cranberries, blackberries as well as red raspberries, or the species Rosaceae Rubus idaeus L. Red raspberries are native to Europe, Northern Africa and Central Asia. They have essential nutrients including beta-carotene and vitamins A, E and C. Only trace amounts of raspberry ketone are found in the fruit, so berry-flavored foods typically use raspberry ketone produced in a lab. Around 2010, scientists noticed that raspberry ketone had a similar molecular structure to capsaicin, which is the chemical responsible for the heat in chili peppers. Preliminary studies also suggested that capsaicin prevents weight gain. In light of these findings, scientists ran studies in mice and on human tissue to see if raspberry ketone also influences weight gain. Does raspberry ketone work? "Reliable research on the use of raspberry ketone for any health condition in humans is currently lacking. Further high-quality research is needed," said Catherine Ulbricht, senior pharmacist at Massachusetts General Hospital in Boston and co-founder of Natural Standard Research Collaboration, which reviews evidence on herbs and supplements. Only a handful of preliminary studies have been done to look at raspberry ketone as a weight loss aid, and none of these were done in humans. But the studies on mice or cells have signaled a potential weight loss effect. A 2005 study on mice fed Continue reading >>

Raspberry Ketone

Raspberry ketone is a chemical from red raspberries, as well as kiwifruit, peaches, grapes, apples, other berries, vegetables such as rhubarb, and the bark of yew, maple, and pine trees. People take raspberry ketone by mouth for weight loss. It became popular for weight loss after it was mentioned on the Dr. Oz television show during the segment called "Raspberry ketone: Miracle fat-burner in a bottle" in February 2012. People apply raspberry ketone to the skin for hair loss. Raspberry ketone is also used in foods, cosmetics, and other manufacturing as a fragrance or flavoring agent. Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate. The effectiveness ratings for RASPBERRY KETONE are as follows: Insufficient evidence to rate effectiveness for... Hair loss (alopecia areata). Early research shows that applying a raspberry ketone solution to the scalp might increase hair growth in people with hair loss. Male pattern baldness (androgenic alopecia). Early research shows that applying a raspberry ketone solution to the scalp might increase hair growth in people with male pattern baldness Obesity. Early research suggests that taking raspberry ketone plus vitamin C might decrease weight and body fat in healthy people. Other research suggests that taking a specific product (Prograde Metabolism, Ultimate Wellness Systems) containing raspberry ketone (Razberi K, Integrity Nutraceuticals) and other ingredients twice daily for 8 weeks reduces body weight, fat mass, waist and hip circumference when used with dieting compared to dieting alone in overweight people.

Raspberry Ketones — Do They Really Help With Weight Loss?

Raspberry Ketones — Do They Really Help With Weight Loss?

Raspberry ketones are chemicals from red raspberries that are thought to help you lose weight fast. Ketones are natural chemicals that give raspberries their enticing aroma, and they also occur in blackberries and cranberries. When ketones are taken from raspberries, they can be used to add fragrance and flavor to foods and products, such as colas, ice cream and cosmetics. The raspberry ketone is actually one of the most expensive products used in the food industry — the natural compound can cost as much as $20,000 per kilogram. That’s why supplement companies use synthetic raspberry ketone, which is much cheaper. Some research in rodents or in test tubes shows that raspberry ketones might increase measures of metabolism and affect a hormone in the body called adiponectin, which regulates metabolism. Raspberry ketones are claimed to cause the fat within cells to be broken down more effectively, which helps the body burn fat faster. The big issue here is that these claims are not supported with human research, as there is no reliable scientific evidence that proves raspberry ketones improve weight loss when taken by people. Are raspberry ketones another common unhealthy way to lose weight? Studies Involving Raspberry Ketones A 2005 study published in Life Sciences evaluated whether or not raspberry ketones help prevent obesity and activate lipid metabolism in rodents. The study involved two groups of mice — one that was fed a high-fat diet and took raspberry ketone doses for 10 weeks and another group that was given a high-fat diet for six weeks first and then began receiving raspberry ketone doses for the remaining five weeks, along with the high-fat diet. The results of the study suggest that raspberry ketones prevent the high-fat-diet-induced elevations in body Continue reading >>

Why Raspberry Ketones Don’t Have Anything To Do With Ketosis

Why Raspberry Ketones Don’t Have Anything To Do With Ketosis

Ever since Dr. Oz promoted raspberry ketones on his show back in 2012, they’ve been all the rage and hailed as the biggest fat-burning miracle supplement. You’ve likely seen the Google ads, the advertisements on TV, and the online “testimonials” talking about its amazing weight loss benefits. But how true is all of this, really? And do these raspberry ketones actually have anything to do with real ketosis? The truth is: raspberry ketones are pointless when it comes to ketosis, and we’ll go into the details here. But first, let’s get a good understanding of what they are and what they claim to do. What are Raspberry Ketones? In its true form, a raspberry ketone is actually found naturally in trace amounts in red raspberries and other fruits like blackberries, cranberries, and kiwis. It’s what gives berries their nice, appealing scent and flavor. Before being sold as supplements, raspberry ketones were mostly used in processed foods like ice creams and soft drinks and in perfumes and cosmetics. How Do Raspberry Ketones “Work”? The claim is that raspberry ketones help the body burn fat faster and more effectively because they supposedly increase levels of adiponectin, which is a hormone that regulates metabolism and blood sugar levels. This is appealing because adiponectin typically increases when you lose weight and those with low levels of the hormone tend to have a higher risk of suffering from type 2 diabetes, obesity, heart disease, and fatty liver disease. Also, the molecular structure of raspberry ketones is close to molecules that have been shown in studies to boost metabolism: synephrine, a stimulant, and capsaicin, a component in chili pepper. The claim here is that raspberry ketones can also boost metabolism because of the similarities. However Continue reading >>

Ask The Diva: Are Raspberry Ketones Safe?

Ask The Diva: Are Raspberry Ketones Safe?

Good question! For those who haven’t yet heard of them, raspberry ketones are the latest weight loss fad. The evidence on raspberry ketones as a weight loss aid is limited to one or two small studies done in test tubes and on rats, showing that ketones increased fat-burning metabolism. Although anecdotal testimony abounds, no scientific trials have been conducted in humans. Not surprisingly, those hawking raspberry ketones note that they work best when used in conjunction with exercise and a reduced calorie diet. Hmmm. As for safety, raspberry ketones have been used as a flavoring agent in food manufacturing for years and have GRAS status (generally recognized as safe). Unfortunately, we don’t know very much about the short or long-term effects of using raspberry ketones as a dietary supplement, which involves much higher dosages than are used in food manufacturing. Chemically, raspberry ketones resemble ephedrine--the stuff that’s kept behind the pharmacist’s counter to prevent its being used to produce methamphetamine. People with high blood pressure, diabetes, kidney disease, anxiety disorders, or who are pregnant or on asthma medicine are advised to avoid medications containing ephedrine or pseudoephedrine. If you’re in that category, I’d strongly advise that you avoid raspberry ketones as well. Bottom line: The alleged benefits of raspberry ketones are too small to warrant either the cost or the unknown risks and side effects. Join me on Facebook and Twitter!

What They Don’t Want You To Know About Raspberry Ketones

What They Don’t Want You To Know About Raspberry Ketones

Before you jump on the raspberry ketone bandwagon, there are a few things you should know about this over-priced, proclaimed weight-loss miracle in a bottle. What is it? Raspberry ketone is the natural phenolic compound found in red raspberries (Rubus idaeus). In simple terms, this chemical compound gives berries their signature scent. Until recently, raspberry ketones were used primarily by the perfume and manufactured food industries, but now the compound is being sold in supplement form. Raspberry ketones have been touted as the next weight-loss miracle drug, with manufacturers claiming that the ketones help your body break down fat more efficiently, helping you to lose more weight. Is it true? Before you run to the pharmacy to pick up a bottle, at least finish reading this blog. What I’m about to share with you might surprise (or downright shock) you! Raspberry ketones have never been tested on humans in scientific studies. That’s right. You read that correctly. To date, there have been no human studies showing that raspberry ketones burn fat or benefit your weight loss. Now, if you are a rat, there are two studies of interest. One study gave male rats raspberry ketones, which resulted in an increased secretion of adiponectin, a hormone secreted by fat cells that helps the body break down fat. The result was less fat on the rat. In another rat study, the rodents were fed a high-fat diet with differing amounts of raspberry ketones. The rats that received more raspberry ketones burned more body fat and gained less fat tissue. A third study exposed fat cells in a test tube to raspberry ketones and found that the raspberry ketones stimulated the breakdown of the fat cells. I’ll agree that this is all very interesting research, but it is also considered very prelim Continue reading >>

Raspberry Ketones

Maybe you've heard the claim that raspberry ketone supplements can melt away fat and prevent weight gain -- even if your diet is high in fat. But what are they, and can they really do that? Raspberry ketones are natural chemicals that give raspberries their enticing aroma. When ketones are taken from raspberries, they can be used to add fragrance and flavor to things such as colas, ice cream, and cosmetics. Experts say that investing in a bottle of raspberry ketone supplements amounts to little more than wishful thinking. And it may or may not be harmful. In one small study, people who took 200 milligrams of raspberry ketones combined with 1,200 mg of vitamin C daily for 4 weeks lost weight and body fat. But the study did not follow good scientific methods. It doesn't show whether any benefit was from either the vitamin C or the raspberry ketones or from the combination. Until more is known, experts say you're better off holding onto your money. Instead, stick to a healthy, balanced diet and regular exercise. Both of those have been shown to be effective ways to manage weight. Raspberry ketones in food and cosmetics are generally considered safe. But no one knows what short- or long-term effect raspberry ketone supplements could have on your overall health. No study has been done to document potential side effects. There are also no studies that look at potential drug or food interactions. The fact that raspberry ketones chemically resemble other stimulants suggests the potential for certain side effects. And there are anecdotal reports of jitteriness, increased blood pressure, and rapid heartbeat among people taking raspberry ketone supplements. Without scientific evidence, no one can say what dosage of raspberry ketone supplements, if any, might be safe to take. Talk Continue reading >>

Is Raspberry Ketone Safe?

Is Raspberry Ketone Safe?

Raspberry ketone skyrocketed to fame when Dr. Oz dedicated a special episode of “The Dr. Oz Show” to exploring the weight loss potential of this raspberry compound. The primary aroma compound of red raspberry, raspberry ketone is said to stimulate fat burning and even suppress the appetite. Over time, this should translate to weight loss. Dietary supplements have since jumped on the raspberry ketone bandwagon, full of promises of smaller dress sizes and washboard abs. But hardly anyone is talking about potential side effects of raspberry ketone. Is raspberry ketone safe? Let’s find out. How Raspberry Ketone Works To know whether or not raspberry ketone is safe, we first have to know how it works. Biologically speaking, raspberry ketone works in two ways to promote weight loss. First, raspberry ketone increases the release of the hormone norepinephrine. Norepinephrine is the same hormone released when you’re in stressful situations. It causes your heart rate to speed up and your body to release more glucose, combining to give you greater energy and physical performance. The second weight loss mechanism works through a protein called adiponectin. Found in fat cells, adiponectin regulates insulin function and reduces inflammation in the circulatory system. This prevents weight gain and risk for type 2 diabetes. One study even found adiponectin increased weight loss by between 18 and 48 percent[1]. Raspberry ketone promotes this process by increasing the secretion of adiponectin. Both mechanisms of action promote weight loss, but they also involve side effects. Here’s a look at a few of the most common raspberry ketone side effects and the reasons why they occur. Jittery Feelings and Rapid Heartbeat As a stimulant, raspberry ketone triggers faster reactions in the Continue reading >>

Raspberry Ketone: The Truth Behind This Banned Fat-burning Slimming Aid

Raspberry Ketone: The Truth Behind This Banned Fat-burning Slimming Aid

In recent years, Raspberry Ketone’s apparent qualities in aiding weight loss have been popular. It’s a chemical compound found in raspberries, blackberries and cranberries, which is not only found in weight loss products, but also in foods as a flavouring and fragrance agent. Results from clinical animal studies have revealed Raspberry Ketone can help enhance the fat burning process and reduce fatty tissue in the body. But while hundreds of versions of the product have hit shelves all over the world it was band in the UK in 2003 by the Food Standards Agency. The reason for its ban came after concerns emerged over its safety and there being no conclusive studies conducted on humans supporting its use as a weight loss supplement. The Food Standards Agency classified Raspberry Ketone as a ‘novel food’ - a type of food that does not have a significant history of consumption or one that is produced in a way that has not previously been used for food. In making Raspberry Ketone a novel food, the Foods Standards Agency has also made it illegal to sell the substance within the European Union. The FSA has put the ban in place to encourage clinical study on the substance while attempting to keep the public safe from any potential dangers that may arise. An FSA spokesperson outlined: “The legal situation with raspberry ketones depends on how they are extracted. “‘Rapsberry Ketone’ (4-(p-hydroxyphenyl)utan-2-one) when used as a flavouring, in compliance with the EU Flavourings Regulation, are permitted on the market. “It is a requirement for all food places on the market that it must be safe and this would include raspberry ketones. Other uses must be compliant with the relevant law.” So what clinical evidence does stand for raspberry ketone aiding weight loss? Continue reading >>

What Is The Recommended Dose Of Raspberry Ketones Extract I Can Safely Take?

What Is The Recommended Dose Of Raspberry Ketones Extract I Can Safely Take?

Are you wondering what the maximum safe dosage of raspberry ketones is? Or are you more concerned about the minimum dosage needed in order to get results? Well the short answer is…It depends on the company selling you the supplements and we will explain why in a moment. First, we need to understand how raspberry ketone supplements work and the studies behind the stats Two key studies have found that raspberry ketones appear to1: Stimulate a reduction in fat build up in the liver and overall reduction of bodyweight after 10 weeks. Improve the fat burning ability of norephinephrine Reduce triglyceride levels at high dosages Raise metabolism Increase levels of adiponectin (which has been found to improve insulin sensitivity) But it is important to note that both these studies were performed on lab mice, using a dosage of 0.5-2.18g/kg which correlates to a human estimated dose of 80-340mg/kg. This would therefore equate to equivalent dosages of: 870-3,700mg raspberry ketone for a 150lb (68kg) person 1,100-5,000mg raspberry ketone for a 200lb (90kg) person These studies also showed that higher doses of raspberry ketone led to improved results. Due to these doses being comparatively high relative to other fat burning compounds, the standard daily supplement dosage is usually found within the 100-500mg range. But the most conclusive human study found that Raspberry Ketone is most effective combined with stimulants such as caffeine. Second, how much raspberry ketone are you getting in your supplement? The second important factor to consider is cost. Due to its highly concentrated nature, Raspberry ketone is an expensive compound, and this has led to many low quality raspberry ketone supplements being released featuring more filler than actual raspberry ketone extract. As a re Continue reading >>
