Mass Gainers & Weight Gain Supplements in Canada

Shop mass gainers and weight gain supplements at SupplementSource.ca. This collection brings together powders with protein and carbohydrates in a range of protein sources, flavours and package sizes. Compare labelled calories, nutrient amounts and servings to choose a formula that fits your food choices and goals.

Compare servings

Serving sizes can vary considerably between mass gainers. Check the amount of powder per serving and whether the nutrition information describes a shake prepared with water or milk. Compare calories, protein and carbohydrates on an equivalent basis, then consider the number of servings in the container and the cost per serving.

Choose your protein source

The collection includes whey-based formulas and plant-based options. Read the full ingredient list to identify protein sources and allergens such as milk or soy. Formulas also differ in their carbohydrate sources and added ingredients. Use the With Creatine filter to find matching products within this collection.

Fit it into your routine

Consider your meals, preferences and the manufacturer’s directions when comparing products. Check the recommended liquid volume, serving size and preparation instructions. If you already use other supplements, compare ingredients and amounts to identify overlap, including creatine. Choose a flavour and format that suit how you plan to prepare your shake.

Make a comparison that fits your needs

Use the filters to explore whey-based formulas, plant-based options or products with creatine. Check each product page for the full ingredient list, allergens and directions. A mass gainer complements your food intake; it does not guarantee a specific result.
