Comprehensive nutrient support Promotes optimum metabolic activity

Energy & Fat Metabolism Factors is designed to safely enhance energy and fat burning metabolism while also combatting fatigue and promoting feelings of well-being. Most importantly, it does so without deceptive or harmful ingredients. In short, Energy and Fat Metabolism Factors provides comprehensive natural support to safely optimize weight-loss when following a sensible regime of diet and exercise.

Our comprehensive fat-burning support being with high level of Carnitine, which is essential for all fat-burning metabolism. We also include Lysine and Vitamin C to further support the body's internal production of carnitine. Is provides our unique B-Complex, including our absorption protected Methyl B12. We also provide extracts of Green Tea and Guarana as natural sources of caffeine-related compounds. These mild "stimulating" botanicals have a history of traditional use to enhance energy and well-being. To combat fatigue and promote feelings of well-being, we also include standardized extracts of the adaptogens Panax Ginseng, Eleutherococcus and Ashwagandha. These plant extracts have long been used to support the body's ability to adapt and recover from fatigue and physical and mental stress, including diet, exercise and weight loss. We also include the branched chain amino acids (Leucine, Isoleucine and Valine) because of their role in preserving muscle during exercise. This comprehensive list of more than a dozen nutrients and botanical extracts can help compensate for the metabolic challenges and fatigue that can accompany diet, exercise and caloric reduction.

Contains no additives or common allergens Contains No milk, soy, yeast, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
