Formulation Notes

Note This product contains a small amount of natural caffeine-related compounds and is not intended for children or those sensitive to caffeine.

This formula’s comprehensive fat-burning support begins with optimum levels of all B-complex vitamins, along with trace minerals such as chromium, as well as all-important carnitine, without which, no fat could be transported or burned. This formula also includes lysine and vitamin C to further support your body’s internal production of essential carnitine. We also provide extracts of green tea and guarana as mild, natural sources of caffeine-related compounds.

To further combat fatigue and promote feelings of well-being, we also include standardized extracts of the adaptogenic herbs, Panax ginseng, eleutherococcus, ashwagandha and Rhodiola.

We also include the branched chain amino acids leucine, isoleucine and valine because of their role in preserving lean muscle tissue during exercise. In short, our Energy and Fat Metabolism Factors supplies natural tools to help you safely maximize your weight-loss potential when you have made the commitment to lose weight via a sensible regime of diet and exercise.

Contains no milk, soy, yeast, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens or manufacturing additives. Contains no additives of any kind.

Comprehensive nutrient support Promotes optimum metabolic activity

All-Solar manufacturing

Andrew Lessman’s Energy and Fat Metabolism Factors is designed to safely enhance energy levels and promote fat burning metabolism while also providing a general sense of well-being. Most importantly, unlike typical formulas, it does so without deceptive or harmful ingredients.

These botanicals have a long history of traditional use to enhance energy and well-being.

These plant extracts have long been used to support the body’s ability to adapt and recover from physical and mental stress, such as diet, exercise and weight-loss. These nutrients and extracts can help us compensate for the natural slowing of our body’s metabolism and the fatigue that occurs when we diet, exercise and reduce our caloric intake.
