Whether you’re a seasoned bodybuilder or someone who struggles to put on muscle, bulking powders can be an essential part of your fitness regime.
Bulking powders are protein supplements that can help you build muscle.1,2
“If we don't have an adequate protein intake alongside exercise, we won't be able to build muscle,” explains H&B nutritionist Emily Foster.
You should get your protein from your diet wherever possible, but sometimes you might need a little extra help.
Discover what protein powders you can use for your fitness journey and how to use them. We’ll also share our top choices to help you choose the right one for your individual goals.
What is bulking?
Bulking is a popular method used by bodybuilders and athletes to gain weight and muscle.3,4
During the bulking phase, a surplus of calories is consumed to gain weight.5 This is combined with weight training and exercise to help build muscle and fat. Bodybuilders then follow up with a cutting phase to lose excess weight.3
While it’s generally agreed that eating more calories helps lead to weight gain,5 extreme fluctuations in weight may put you at risk of poor health outcomes.6 Overconsumption of junk food and highly processed foods, also called ‘dirty bulking’, may put you at risk of high blood sugar levels, obesity and type 2 diabetes.7-9
A ‘clean’ bulking approach involves eating a tightly controlled calorie surplus and sticking to healthier or unprocessed food.10
Can protein powders help with bulking?
If bulking is your goal, getting enough daily protein and carbs is essential to putting on muscle mass and maintaining strength.2 Research has found that combining exercise and resistance training with sufficient dietary protein and a balanced diet can also help you to build muscle.11
“For someone who’s regularly doing sports and exercise – particularly strength training – research suggests that around 1.2-2 grams of protein per kilo of bodyweight is optimal,” Emily says.12
When used as part of a clean bulking diet, protein powders can help you achieve your daily protein goals.1
Some common protein powders that you can use for bulking up include:
- whey protein powder
- casein protein powder
- mass gainers
- vegan protein powders (soy, pea, hemp and rice)13,14
What is mass gainer protein powder?
Mass gainers are just one type of bulking protein powder. They’re specially formulated blends that combine protein (typically whey protein) with high-carbohydrate ingredients and fats.15
If you want to gain weight and muscle mass by increasing your calorie intake, you may find that mass gainers can help you meet your daily calorie goals – especially if you struggle to do so through diet alone.5,15
How to use bulking protein powders
“For a lean bulk, you might want to moderately increase your calories using nutritious foods that provide your body with vitamins and minerals. An easy way to do this is simply to upgrade your protein smoothie. So instead of just having protein powder with water or skimmed milk, you might switch to full fat milk and throw in some oats, nut butter, fruit and chia seeds,” says Emily.
“For a bigger bulk-up, a mass gainer will deliver a high protein content, which will contribute to muscle growth and maintenance, along with carbs which act as your body's main energy source to help fuel recovery.”
You can incorporate bulking powders into your diet however works best for you. Many people mix or blend their protein powder with water, milk or their favourite beverage. You can also add them to smoothies, stir them into soups or even use them in your favourite baking recipes.
Some people also like to take bulking powders after their workout. When ingested immediately or up to two hours after your workout, protein supplementation may help stimulate muscle growth.16,17
However, the latest research suggests that hitting your overall daily protein goal is more important than timing. If your goal is bulking up and maintaining muscle mass, it may be best to time your high-quality protein consumption throughout the day in three-to-four-hour increments.11,16,18
Preferably this protein should come from a range of food sources in your diet including plant proteins, but if you’re struggling, then you can supplement with protein powders ‒ more on this below.

But that’s not the only way to fuel your body. Learn how to get enough protein in your diet and why rest is essential for muscle growth too.
Finally, always consider your fitness and nutrition goals and check with your GP, dietitian or healthcare professional before starting any new weight-related programme.
