Weight Gainer

What Are Weight Gainers and What Are They For?

Weight gainers, also known as mass gainers, are high-calorie dietary supplement powders formulated with a blend of proteins, carbohydrates and fats. They are designed primarily for hard gainers and ectomorphs — people who struggle to put on weight — and for anyone who needs a significant caloric surplus to support a muscle-building phase.

What types of mass gainer are there?

Not all gainers are the same. Depending on their composition, the main categories are:

• Classic Mass Gainer: very high in carbohydrates (up to 250–300 g per serving) and protein. Best suited for those with a very fast metabolism who need large amounts of calories.
• Lean Gainer: a more balanced formula with fewer simple carbs and higher protein content. Ideal for those who want to gain muscle while minimising fat accumulation.
• Vegan Gainer: made with plant-based proteins (pea, rice, soy) for those following a plant-based diet.

The right choice depends on your metabolism, goals and daily diet.

When and how should you take a weight gainer?

The best time to take a mass gainer depends on your schedule and daily calorie needs:

• Post-workout: straight after training to support recovery and muscle growth.
• As an extra meal: between meals or before bed to hit your daily calorie target.
• Pre-workout: to fuel your training session with readily available energy.

Mix the powder in water or milk following the label instructions. Food supplements are not intended as substitutes for a varied and balanced diet or a healthy lifestyle.
