Nutritional information may vary depending on flavour. What is a weight gainer? If you’re looking to gain weight, build strength, or increase size then you’re going to have to consume more calories than you burn throughout the day - known as a calorie surplus. And, although that sounds really simple, eating the wrong types of foods can lead to an increase in body fat, which isn’t ideal. To gain muscle you must combine a calorie surplus, with high-quality protein sources - which contribute to the growth and maintenance of muscle mass1 - and a well thought-out strength training plan. We know that getting your nutrition right, when leading an active lifestyle, can be difficult - and that’s where we come in. Our weight-gainer supplements combine high-quality ingredients with ultimate convenience, delivering the fuel you need, wherever you are. What is Impact Weight Gainer?
