Meal Replacement formulas are designed to take the place of a regular meal in order to either reduce your calorie intake to lose weight or to supplement your calorie intake in order to gain weight. Meal Replacements contain nutrients that ensure your body is well fed, such as vitamins, minerals, amino acids, proteins and carbohydrates. Meal replacements for losing weight tend to be low in carbohydrates and contain appetite suppressants and stimulants to reduce your hunger and increase your ability to burn calories. We also stock low carb proteins and bars that can be used to curb hunger in order to reduce your daily meals. Meal Replacements to gain weight are high in carbohydrates and proteins and will contain limited stimulants and no suppressants. For sports strength weight gain, have a look at our category called Weight Gain. It is very important to always read the label and follow the instructions on all supplements as each manufacturer has different requirements. Please also note that these products are not suitable for people under the age of 15.
