Why Oligolean

How many calories you eat versus how many calories you burn impacts your weight, but it’s not the whole story. If you start eating less and exercising more, your metabolism may respond like it did for our caveman ancestors when food was scarce — namely, by slowing down. When that happens, you may stay at the same weight despite consuming fewer calories.

When it comes to how much you weigh, all kinds of metabolic factors are in play, including your blood sugar, your fat metabolism, your hormones (we’re looking at you, insulin and cortisol!), and your appetite.

Unlike supplements focused solely on calorie burn, Oligolean™ is a holistic weight management formula that gives your whole metabolism a tune-up. In addition to targeting calorie expenditure, it also supports healthy body weight; abdominal circumference; fat metabolism; hormone, blood sugar and blood lipid levels; and appetite.*

our ingredients


Oligonol® is a low-molecular-weight, highly absorbable polyphenol made from lychee fruit and green tea. When used in conjunction with a healthy diet and exercise, Oligonol® has been clinically shown to decrease body weight, waist circumference, and abdominal fat.* It may work in part by decreasing cortisol, a hormone linked to belly fat, and increasing lipolysis (the breakdown of triglycerides for energy).* Oligonol® also helps maintain blood sugar and blood lipids already within normal limits.* Oligonol® won the prestigious NutraCon “Top Evidence-backed Products of the Year” NutrAward in 2008.

Yerba Maté

Yerba Maté is native to South America, where the plant’s antioxidant-rich leaves have been steeped and consumed as a beverage for hundreds of years. Clinical research has shown that combining yerba maté with exercise significantly increases fat burning and energy expenditure.* Yerba maté has also been shown to decrease hunger and keep appetite in check.*

Packaged in the USA

We package almost all of our products in glass bottles with metal lids for one simple reason: Glass and metal do the best job of protecting our supplements from light, oxygen, and moisture — all of which can degrade vitamins, minerals, botanicals, and other nutraceuticals and lessen their potency and freshness.


When you choose Quality of Life, you can trust your supplements to work, because 100 percent of the ingredients in every product we manufacture are provided in dosages that match the clinical research.
