Quick Facts

Who Progressive Grass Fed Whey Isolate Is For

• Adults wanting New Zealand grass-fed whey isolate with clean-label natural sweetening
• People who specifically prefer stevia-sweetened protein over artificial sweeteners
• Customers who've been using Precision All Natural Whey Isolate Protein and want to continue with the rebranded Progressive product
• Strength trainers and athletes wanting clean whey isolate sourcing
• Adults with mild lactose sensitivity — isolate format has minimal lactose
• Canadians supporting sports nutrition from one of Canada's long-trusted natural health brands

Who this product is NOT for: If you have a dairy allergy (not just lactose intolerance), avoid whey isolate — even isolates contain milk proteins. It also contains soy. Plant-based protein is the right alternative — see Progressive Harmonized Fermented Vegan Protein or Progressive VegEssential All in One. If you don't like stevia (some people taste it as bitter), this may not be the right fit. If you prefer a whey concentrate, see Progressive Grass Fed Whey Protein. If you want whey with added collagen and MCT, see Progressive Grass Fed Whey + Collagen & MCT.

Vitamart's Take

Progressive Grass Fed Whey Isolate is 100% New Zealand grass-fed whey protein isolate, sweetened only with stevia and no artificial sweeteners. The formula keeps things simple with quality whey isolate and a straightforward ingredient list. If you've used Precision All Natural Whey Isolate in the past, this is the same product under the Progressive name, now with updated branding.

How Progressive Grass Fed Whey Isolate Compares

Why New Zealand Whey Matters

New Zealand has a unique position in the global dairy supply:

• Year-round pasture-raised: New Zealand's mild climate allows cows to graze on grass year-round, producing whey with a cleaner profile than industrial dairy operations that rely heavily on grain feeding.
• Strict regulatory standards: New Zealand has some of the strictest dairy quality and traceability standards globally, including bans on certain hormones and antibiotics used in other industries.
• Naturally higher CLA and omega-3: Grass-fed dairy contains naturally higher levels of conjugated linoleic acid (CLA) and omega-3 fatty acids compared to grain-fed dairy.
• What this means for the protein: The amino acid profile is the same, but the overall nutritional context is cleaner — lower environmental contaminants, no synthetic hormones, and a healthier fatty acid profile in any residual fat.
• Price reflects sourcing: New Zealand whey is higher-cost than industrial dairy whey. The cost reflects the sourcing standards, not marketing markup.

How To Use

Adults: Add 1 scoop (40 g) to 250 ml of cold water, milk, or the beverage of your choice. Best consumed within 30-60 minutes after training for post-workout recovery, or anytime during the day to support daily protein intake.

For most adults, 1-2 scoops daily covers protein supplementation needs. Total daily protein intake of 1.2-2.0g per kg of body weight supports muscle growth and recovery for active adults. Talk to a healthcare practitioner before use if you have kidney disease or a chronic medical condition.
