Frequently Asked Questions
What is the best protein powder in Canada?
The best protein powder in Canada depends on your goal also personal customer preference. For lean muscle and post-workout recovery: Dymatize ISO 100 or Rule 1 Whey Protein Isolate are currently 2 of the top selling protein options. For everyday use and value: Basic Supplements Whey Blend or Allmax Allwhey Classic Whey Protein. For bulking: Dymatize Super Mass Gainer or Optimum Nutrition Serious Mass. For dairy-free: a plant-based protein from PEScience Vegan Protein or ANS Fresh1 Plant Based Protein.
What is the difference between whey protein and whey isolate?
Whey protein concentrate retains more fat and lactose from milk — typically 70–80% protein by weight with more calories per serving. Whey isolate is further processed to remove most fat and lactose, resulting in 90%+ protein by weight, fewer calories, and better tolerance for those with lactose sensitivity. Isolate costs more but is superior for lean muscle building and fat loss phases.
When should I take protein powder?
The most impactful timing is after training (whey isolate for fast absorption) and before bed (casein for slow-release overnight recovery). That said, total daily protein intake matters more than exact timing. Use protein powder whenever it helps you hit your daily protein target of 1.6–2.2g per kilogram of bodyweight.
Is plant-based protein as effective as whey?
High-quality plant-based proteins — particularly pea and rice blends — are nearly as effective as whey for muscle building when total protein intake and leucine content are matched. They are an excellent choice for vegans, those with dairy allergies, or anyone preferring a plant-sourced option. Look for plant proteins with at least 20–25g protein per serving.
