Protein powder is a convenience product, not a magic muscle-builder. If you can hit your protein target from food, you don’t need it. If you can’t, a scoop a day is the cheapest way to close the gap.
Who actually benefits
Active adults targeting 1.6+ g/kg/day who struggle to get there from food. Older adults fighting sarcopenia. Vegan Canadians consolidating amino-acid coverage.
Whey vs. plant-based
Whey isolate remains the cheapest high-quality option at Canadian retailers. Pea protein or a pea-rice blend is the best plant-based alternative. Soy protein isolate works fine for most adults — despite decades of outdated rumours.
What to avoid
Proprietary “blends” that hide protein amounts. Mass-gainer products (mostly sugar). Brands with no NPN or third-party testing.
The bottom line
One 20–30 g scoop a day if your protein target is hard to hit. Whey isolate for most Canadians; pea+rice blend for plant-based.
