Raspberry ketones are the compounds within raspberries that give the fruit its characteristic aroma. More important to dieters, however, is new research showing these compounds can also melt away the pounds.

According to Lisa Lynn, a leading weight-loss expert and television health contributor, many of her clients have been supplementing with raspberry ketones and experiencing stunning fat-loss results in as few as five days

Lynn described the compounds as "very healthy" with "no side effects" and says the pills enable the body to "burn fat easier" by stimulating the production of adiponectin, a hormone found in fatty tissue that improves our ability to metabolize fat.

Studies show that thin people have higher levels of adiponectin than overweight individuals. What's more, researchers agree that the hormone improves insulin sensitivity and helps regulate weight.

Stores Struggle to Keep the Fat Buster in Stock

Indeed, supplements containing raspberry ketones have become nearly impossible to find in stores after a popular TV doctor, mentioning no specific brand, proclaimed it "The number one miracle in a bottle to burn fat" on his daytime TV show.   

Health food stores across the U.S. have been barraged from customers seeking the slimming superfruit extract. At Planet Nutrition in Charlotte, N.C., the phone has been ringing off the hook as soccer moms, fitness buffs, and people who just want to slim down search for raspberry ketones, according to FOX NEWS.

Manager Gage Bryant says, “It's just crazy with the amount of calls, customers coming in, and having it on back order for another week or two from the distributors. I mean, it's a big deal."

Even stores that don't typically stock the product are taking note.

Healthy Home Market Natural Remedies Consultant Joy Fanning says, “So many people have come swarming in we've had to take special orders." The Healthy Home Markets have fielded lines and placed more than 200 orders for the fat burner.

Note: Raspberry Ketone Has Sold Out in Most Stores — As Of Today, , Supplies Still Available Online.

Good luck trying to find raspberry ketones in stores. Many U.S. health-food retailers like GNC have been on backorder since February. Even stores in the United Kingdom are completely sold out of the fat buster, according to a new report in Britain's Daily Mail online.

A few online retailers, who stocked up on raspberry ketone before the craze hit, still have supplies available to customers.

Consumer Tip: Avoid most bargain-basement "Raspberry Ketone" products advertised on Google, as well as other online search engines — more often than not, these are cheap imitation knock-offs imported from China. These low-quality rip-offs will not deliver the same results of pure American-manufactured, pharmaceutical-grade Raspberry Ketone products.

According to consumer and Better Business ratings, the Raspberry Ketone Fat-Loss Formula from Applied Nutritional Research is considered one of the most effective and trustworthy, with laboratory tests certifying the product's potency and quality.

Each serving of the Raspberry Ketone Fat-Loss Formula contains 300 mg of raspberry ketones — one of the highest concentrations currently available (most products offer just 100 mg per serving).

The website offers a 100% risk-free trial of the product, with each serving working out to be just 62 cents — less than what you'd spend on a small sugary softdrink at McDonald's.

What's more, each an every order of the Raspberry Ketone Fat-Loss Formula is a one-time-only transaction. In other words, there are absolutely no reoccurring charges or hidden offers.
