Slow metabolism is a result of many aspects including low caloric diets, inactivity and the normal process of aging. By focusing on thyroid activity, Thyrene® uses proven ingredients to increase your metabolic rate, improve energy, and help you achieve your weight loss goals more effectively.* Thyrene has been scientifically engineered to target specific areas that most thermogenic and fat loss products fail to attack. By concentrating on thyroid function, Thyrene uses specific ingredients to help you take charge of your slowing metabolism.* The effects of highly restricted diets, general aspects of aging, and inactivity can wreak havoc on your metabolic rate by reducing the effectiveness of key hormones and enzymes. Thyrene is designed to improve fat mobilization, increase metabolic activity and provide additional energy all day long. Further, due to its unique ingredient combination, Thyrene can be used along with high stimulant pre-workout drinks, stimulant based thermogenics, other energy drinks making it the perfect addition to any serious weight loss program. Since Thyrene is so powerful, we recommend assessing tolerance by using it initially without any other weight loss products.*
