Weight Gain

If you’re trying to put on mass, our range of weight gain supplements can help you put on mass and build muscle.

Weight gain supplements can help you increase your muscle mass or maintain your body weight by increasing your calorie consumption and protein intake. These formulas are usually high in slow & fast-releasing proteins, as well as carbohydrates from different sources and creatine.

Maximise Results with Weight Gain Supplements

Weight gain supplements commonly come in the form of mass gainers, protein powders and creatine to help you put on weight and maintain weight. When it comes to choosing the right supplements, it is important to consider your goals.

To put on weight, a mass gainer like Evolve Incredible Mass, Optimum Nutrition’s Serious Mass, Rule 1 LBS and MuscleTech’s Mass-Tech can help you improve your caloric intake while increasing your consumption of protein and carbs.

What are the ingredients in weight gain supplements?

Who should take weight gain supplements?
If you struggle to gain weight, maintain weight, or meet your desired caloric intake, then you may find a weight gain supplement beneficial. If you need more protein and calories to support muscle building after intense training, then a weight gain supplement or mass gainer may help you achieve your goals (Richards, L et al. 2022).

Who should not take weight gain supplements?
Weight gain supplements are high in protein and carbohydrates and may not be suitable for people with diabetes or insulin resistance. Additionally, if you are already meeting your caloric intake or are overweight, you may not need a weight gain supplement. As most supplements use whey protein, you may find these formulas ineffective if you are lactose intolerant or sensitive. There are plant-based alternatives that may suit you (Richards, L et al. 2022).

How do I choose a supplement for weight gain?
Choosing the right weight gain supplement will depend on your goals, dietary needs and preferences. You should look at the nutritional panel and determine whether the macronutrients and calories suit what you are looking for. Some formulas will contain vitamins, minerals and creatine to support muscle building, while others may contain ingredients more suitable for weight gain and muscle recovery.
