Known as the "fight or flight" hormone, too much cortisol can cause dangerous symptoms including an increased heart rate and insomnia. Whey protein has been shown to help lower cortisol levels which, in turn, offers protection from the negative effects of stress. Whey protein also stimulates the production of lean muscle, helps to reduce body fat, producing a more defined, toned look, and provides long-lasting energy throughout the day. Flex Fit Pro also contains eight essential amino acids that help to boost the body's immune system. Flex Fit Pro provides lean proteins without added carbohydrates and fats and is low in calories. In addition, Flex Fit Pro is lactose friendly, gluten-free and non-GMO. A serving size of one scoop (33gm) of Flex Fit Pro mixes easily in water, milk, or other liquids to provide long-lasting, post-workout energy that lasts throughout the day. Each container of Flex Fit Pro contains 30 servings. Flex Fit Pro comes in two delicious tasting flavors -- angel food cake and chocolate milkshake.
