What Are Weight Gainers & Muscle Mass Gainers?

Weight gainers and muscle mass gainers are specialised sports nutrition supplements that are a concentrated source of calories. These calories are sourced from a blend of carbohydrates, protein and healthy fats. They help you achieve the calorie surplus and protein intake required to build muscle and gain bodyweight in a controlled way.

Unlike standard protein shakes, gainers have a higher calorie content per serving and are ideal for people who struggle to eat enough food, have fast metabolisms or are training intensely. Many weight gainers also contain vitamins, minerals and digestive enzymes to support energy metabolism and enhance gut comfort.

Benefits and Features of Weight Gainers & Muscle Mass Gainers

High caloric profile: These supplements have extra calories that ensure a caloric surplus without relying on large meals.
Quality protein source: They are sources of high quality proteins to support muscle repair and enhance growth. They increase muscle size and thus lean muscle mass.
Convenient to use: These easy-to-mix supplements must be before or after the gym, or between meals. The replenish glycogen stores in the body to ensure quick post workout recovery.
Complementary sports supplements: Our gainers pair well with BCAA supplements, amino acids and pre-workout formulas to support performance and recovery.
Trusted brands: We stock mass gainers from well-known sports nutrition companies. These brands are present in our wider sports supplements range.

Why Are Weight Gainers & Muscle Mass Gainers so Important?

It is not easy to build lean muscle mass and gain weight with just food. Hard gainers, people with naturally high energy expenditure, and athletes with heavy training schedules quickly burn calories. A structured mass gainer such as a protein shake can help you gain weight in a steady way.

Combination of a gainer and resistance training, adequate sleep and a balanced diet can support muscle growth & recovery rather than uncontrolled fat gain. Our collection complements targeted health ranges such as heart health supplements and joints, bones & muscles support, helping you build mass with long-term wellbeing in mind.

How to Use Weight Gainer & Muscle Mass Gainer Supplements?

Most gainers mix easily with water or milk and should be consumed once or twice a day, depending on your calorie targets. Many people prefer to take a serving:

After training to support recovery and muscle repair.
Between meals as a convenient calorie top-up.
In the evening if they struggle to hit daily calorie goals.

If you’re already using products from our post-workout snacks or recovery supplements collections, you can stack them with a mass gainer, adjusting your total calories accordingly. Always follow label instructions and speak with a healthcare professional if you have underlying health conditions.

What Are the Different Types of mass gainers & protein supplements Available?

We have a variety of weight gainers and you can choose one that fits your training style and dietary preferences:

High-carb gainers: They suit people engaged in high-volume training or endurance athletes who need more carbohydrates to fuel their sessions.
Balanced carb–protein gainers: They are classic choice for strength athletes who want a combination of protein and carbs.
Higher-protein gainers: They suit those who already consume a moderate amount of carbohydrates in their diet but need extra protein.
Specialised formulas: We have options with added creatine, performance ingredients and digestive enzymes.

We have additional products to support your protein intake such as protein bars, meal replacement shakes and vegan protein supplements. They are for you even if you follow a plant-based diet.

Frequently Asked Questions

Who should consider using a weight gainer?

Weight gainers are suitable for people who struggle to gain weight through food alone. They are those with very active jobs and athletes with high training volumes.

Will a mass gainer make me gain fat instead of muscle?

If you combine a moderate calorie surplus with regular resistance training, most of the weight you gain is more likely to be lean tissue. Very large surpluses or a lack of training can increase fat gain.

Can I use a mass gainer shakes on rest days?

Many people continue to use their gainer on rest days to keep their weekly calorie intake consistent, adjusting portion sizes if needed.

Is a gainer better than a standard protein powder?

Neither is inherently better; they serve different purposes. Protein powders focus on protein intake, while gainers provide both protein and higher calories from carbohydrates and fats.

Can I take a gainer if I am new to the gym?

Yes, beginners can use gainers, but it’s important to start with sensible portions, follow a structured training plan and control your daily calorie intake for healthy muscle development.

How long does it take to see results from a mass gainer?

Most people notice changes in weight and strength over several weeks if they are consistently in a calorie surplus and following a progressive training programme.

Can weight gainers upset my stomach?

Some people may experience bloating or discomfort if they use very large servings or have sensitivities to certain ingredients. Starting with smaller portions and choosing formulas with added digestive enzymes may help.

Do I still need to eat regular meals if I use a gainer?

Yes. Weight gainers are designed to supplement, not replace, a balanced diet based on whole foods such as lean proteins, whole grains, fruits and vegetables.
