You hear about them everywhere -- superfoods. They are natural and nutrient dense, packing a punch and promising health and wellness in a tiny pill.
"I have been taking supplements for years," Suzette Lang said.
Elizabeth Long agreed, "Probably for about 15 years I've been taking them."
"I start my morning with an array of supplements and I take some with breakfast and I take some at lunch and then with dinner and if I don't take them, I immediately notice a difference and I hear that from my customers all the time," said Amrita Menon, who owns a vitamin store in Houston.
Kimberly Olson is a certified nutritionist, personal trainer, and author of The FitKim Lifestyle and revealed some of her favorite slimming superfoods.
She said, "Look at me! I have so much energy and I swear it's because of all these superfoods I take."
You've probably heard of one -- green coffee bean extract.
Olson said, "That is absolutely hands down out of all of them my favorite."
The craze over green coffee bean extract took off after getting a stamp of approval from Dr. Oz. "It'll help you lose about a pound a week faster than you would've lost (without it)," he said.
Dr. Oz said you should buy green coffee bean extract containing 45 percent chlorogenic acid, the key ingredient.
Olson added, "When you take it before a meal, the chlorogenic acid inhibits your body from using your food as fuel and forces your liver to metabolize your stored fat and use that as your energy source."
Dietician Carol Wolin-Riklin said before you jump on the bandwagon, read the label carefully.
"Everybody's looking for hope in a bottle. The one thing you have to be careful of is every brand of green coffee bean is different. Some have fillers such as caffeine and other products added to it, so it's not always the same product in the bottle," she said.
Another superfood to add to the mix -- raspberry keytone. Olson refers to as the "triple threat."
"It's going to help your body burn more calories at rest. It inhibits how much fat it stored in your body and it breaks down fat cells," she explained.
Suzette Lang swears by it.
"It's really picked up my metabolism. I have energy (and it) really helps suppress those urges to kind of pig out," Lang said.
Another superfood has been around for generations. It's called moringa tree. Known around the world as the miracle tree, it's believed to reduce cravings, curb the appetite and more.
Olson said, "It has over 45 different types of antioxidants. Ounce for ounce, it has 25 times the amount of iron found in spinach, 15 times the amount of calcium found in milk and nine times the amount of protein found in yogurt."
Another superfood may be hard to pronounce -- garcinia cambrogia, but fans of it believe in what Dr. Oz has called the Holy Grail of weight loss supplements.
