How much whey protein should I take per day?
1–1.6g of protein per kg of bodyweight per day is well-supported for muscle building. Most people need 1–2 scoops across meals. Get as much as possible from whole foods first, and use whey to bridge the gap.
Whey concentrate vs isolate — which should I buy?
Concentrate is the better value for most people — 75–80% protein, cheaper per gram. Isolate (90%+ protein, near-zero lactose) is worth the premium only if you're lactose intolerant or cutting and need calories tight.
When is the best time to take whey protein?
Post-workout is classic, but total daily protein matters most. Whey at breakfast, post-workout, or before bed all work. Don't overthink timing — consistency over weeks beats perfect timing.
Is whey protein vegetarian?
Yes — whey is a byproduct of cheese-making and contains no meat. It's lacto-vegetarian. Vegans should look at pea protein or soy isolate instead.
How do I verify if my whey protein is genuine?
Buy from Amazon.ca official brand stores or authorised distributors. Look for a Health Canada Natural Product Number (NPN) on the label, plus third-party lab certification (Informed Sport or NSF Certified for Sport) where available.
