Whey isolate, concentrate, casein, vegan — what is the difference?

All protein powders provide concentrated dietary protein, but they differ in source, processing, digestion rate, and price per gram of protein.

Whey isolate — most filtered form. ~90% protein by weight, typically 25–30g protein per serving with minimal carbs/fat and very low lactose. Premium price.
Whey concentrate — less filtered. ~70–80% protein. More flavour, more lactose, more affordable per gram of protein.
Whey blends — concentrate + isolate (sometimes + casein). Balances cost and protein density. Most popular format.
Hydrolysate — pre-digested whey, absorbed faster. Premium positioning.
Casein — slow-digesting milk protein. Often used before bed or as a meal-replacement that stays satisfying longer.
Vegan blends — typically pea + rice + hemp combinations. Lactose-free, plant-based.

Choose by lactose tolerance, dietary preference, training goals, and cost per gram of protein. Consult a healthcare professional for guidance specific to your situation.

Frequently asked questions

What is the best whey protein in Canada for beginners?

For most beginners, a whey blend (concentrate + isolate) like PEScience Select Protein or Mutant Whey gives a good balance of cost and protein density. If you have lactose sensitivity, choose a pure isolate like Allmax IsoFlex or PVL IsoGold.

How much protein powder should I take per day?

Most dietary guidelines suggest 1.2–2.0g of protein per kg of body weight daily for active adults, depending on training intensity and goals. Protein powder is one tool to help meet that target alongside whole foods. Consult a healthcare professional or registered dietitian for personalised guidance.

What is the difference between whey isolate and concentrate?

Isolate is more filtered — ~90% protein by weight, minimal carbs/fat, and very low lactose. Concentrate is ~70–80% protein, more affordable per gram, more lactose, and typically more flavourful. For lactose sensitivity, choose isolate.

Is whey protein safe?

Whey protein is widely used as a dietary protein source. As with any supplement, consult your healthcare provider before starting, particularly if you have kidney concerns, dairy allergies, or are managing a medical condition.

What is Informed Choice / Informed Sport certification?

Informed Choice and Informed Sport are third-party testing programs that verify a product is free from banned substances. Useful for athletes subject to drug testing. In our protein powder collection, Allmax products carry Informed Choice certification.

Can vegans use protein powder?

Yes — plant-based protein powders use blends of pea, rice, hemp, and other vegan sources. Our collection includes options from North Coast Naturals and other vegan-formulated brands.

Is whey protein safe for women?

Whey protein is a dietary protein source used by both men and women. Many women include protein powder as part of meeting daily protein targets. Consult a healthcare professional for guidance specific to your situation.
