Why Choose a Mass Gainer Protein?

If you’re struggling to hit your calorie goals through food alone, a mass gainer can be a powerful tool in your training plan. Unlike standard protein powders, weight gainers combine high-quality protein with carbohydrates and fats to create a more calorie-dense shake. Ideal for building mass or recovering from intense training blocks, a mass gainer protein helps bridge the nutritional gap and supports muscle development. 

How to Use a Weight Gainer Effectively

Consistency is key when it comes to getting the most out of your weight gain shakes. We recommend adding it to your post-workout routine or between meals for a calorie boost, but make sure you’re pairing it with a balanced diet and progressive strength training for best results.

Frequently Asked Questions about Mass Gainer

What are mass gainers?

Mass Gainers, like Kinetica Sports Oatgain are supplements that offer a higher calorie option compared to traditional whey protein. The aim of a mass gainer is to increase an individual’s overall calorie intake, particularly if they find it difficult to consume the calories through food alone. Mass gainers contain a blend of carbohydrates and protein, both which are important macro-nutrients for providing energy and supporting lean muscle growth.

Read our blog explaining what is a mass gainer.

Are mass gainers good for your body?

Mass gainers can be beneficial, especially for people who struggle to gain weight (often referred to as ‘hard gainers’). They’re designed to provide a high number of calories from a mix of carbs, protein and sometimes fats, making them a convenient way to support muscle growth and weight gain. They can be used as a meal replacement if you’re short on time, or as a post-workout recovery option thanks to their blend of macros.

Who should use mass gainers?

A mass gainer can be used by anyone involved in field sports such as rugby and football, but also in sports like rowing where energy expenditure is high and there would need to be an increase in overall calorie intake due to the demand of the sport.

You do not need to be involved in sport to use a mass gainer. If you perform resistance training and are looking to increase lean muscle mass, then a mass gainer like Kinetica Sports Oatgain can be of benefit.
