Mass Gainers

Shop Mass & Weight Gainers at Holland & Barrett

Whether you're underweight and looking to gain healthy mass or a fitness enthusiast aiming to build muscle, we've got the perfect solution to support your journey.

Mass gainers are dietary, weight gain supplements that help you build lean muscle mass, and gain weight safely. While similar to other protein powders, mass gainers are different in that they typically contain a high number of calories, carbohydrates, proteins, and sometimes fats.

These powerful protein supplements are packed with concentrated protein from various sources like whey or casein, to allow you to gain lean mass. Usually, mass gainers are consumed in the form of a shake, mixed with water or milk.

At Holland & Barrett, we want to support you on your healthy weight and muscle gain journey. That’s why we supply a wide variety of mass gainer protein powders from top brands like USN, Optimum Nutrition and PE Nutrition. With a range of mouth-watering flavours like strawberry, vanilla, and chocolate, we have a weight gainer for every palate.
