Efectiv Grass fed Whey Protein Isolate 2kg

Efectiv Grass Fed Whey Protein Isolate – 27g Protein. 90% Purity. Zero Compromise.

Not all whey protein is created equal. Whey Protein Concentrate is the industry standard — good, reliable, but diluted with lactose and fat that don't contribute to your protein goals. Whey Protein Isolate is the refined version: ultra-filtered to strip away the unnecessary, leaving behind a purer, leaner, more concentrated protein source.

Efectiv Grass Fed Whey Protein Isolate takes that refinement a step further. Using ultra-filtered WPI90 sourced exclusively from European grass-fed dairy cattle, every 30g scoop delivers a substantial 27g of protein — naturally low in fat, low in sugar, and significantly lower in lactose than standard whey, all without compromising on the smooth texture and great taste Efectiv have built their reputation on.

This is whey protein stripped back to what actually matters: maximum protein, minimum everything else.

Key Benefits

27g of Protein Per Serving — 90% Protein Content

Efectiv's WPI90 designation isn't marketing — it's the actual protein content of the isolate used, achieved through an ultra-filtration process that concentrates the protein fraction of whey while filtering out the majority of fat, lactose, and other non-protein components. The result is one of the highest protein-per-scoop ratios available in a whey isolate, at 27g of protein from a single 30g serving — a 90% protein yield that few products on the market can match.

Low in Fat & Sugar by Nature, Not by Compromise

At just 0.81g of fat and 0.39g of sugar per serving, this isn't a "diet" protein with artificial low-fat reformulation — it's simply what ultra-filtration naturally achieves. The filtration process that concentrates the protein content simultaneously removes the fat and lactose that would otherwise dilute it, making WPI90 inherently lean without any trade-off in protein quality or taste.

Low Lactose — Friendlier on Digestion

Standard whey protein concentrate retains meaningful levels of lactose, which can cause bloating, discomfort, or digestive issues for those with lactose sensitivity. Because Whey Protein Isolate is filtered far more extensively than concentrate, the lactose content drops to incredibly low levels — making Efectiv Grass Fed WPI a genuinely good option for those who find standard whey protein difficult to digest, without needing to switch to a more expensive or less effective alternative protein source.

100% Grass-Fed Sourcing

Sourced exclusively from European grass-fed dairy cattle, this isolate reflects a more natural feeding and farming approach compared to grain-fed dairy production. Grass-fed dairy is widely associated with a more favourable fatty acid profile and a cleaner overall nutritional footprint — an important consideration for those who care about the sourcing standards behind their supplements, not just the numbers on the label.

No Proprietary Blends — Full Transparency

What you see is what you get. Efectiv don't hide ingredients behind proprietary blend labelling — every component is listed clearly, with the isolate itself standardised and consistent batch to batch. No guesswork, no inflated label claims, just a clean, verifiable protein source.

Smooth Texture, Genuinely Great Taste

Whey isolate has a reputation for being thinner and less satisfying to drink than whey concentrate — Efectiv set out specifically to fix that. Using modern flavour technology and careful formulation, this isolate delivers a smooth, creamy mixing experience without the watery texture isolates are sometimes known for, while still keeping the macros lean.

Whey Isolate vs Whey Concentrate — What's the Difference?

Both are excellent protein sources, but they're processed differently and suit slightly different priorities:

• Whey Protein Concentrate (WPC) – typically 70-80% protein, retains more naturally occurring fat and lactose, generally more cost-effective, and excellent for general daily protein needs
• Whey Protein Isolate (WPI) – filtered further to 90%+ protein, significantly lower fat, sugar, and lactose, faster digesting, and the preferred choice for those tracking macros tightly, managing lactose sensitivity, or wanting the leanest possible protein source

If you want maximum protein with minimum everything else, isolate is the smarter choice — and Efectiv's WPI90 sits right at the top end of what's achievable through ultra-filtration.

How to Use

Mix 1 scoop (approximately 30g) with 200ml of chilled water in a shaker.

• Consume 30 minutes post-workout for optimal recovery support, or any time extra protein intake is needed throughout the day
• For a creamier shake, use milk instead of water — note this will add extra calories and fat
• Add to smoothies, porridge, or recipes for a versatile way to boost the protein content of any meal
• Try it as a frappe: blend with chilled water, ice, and a shot of espresso for a high-protein iced coffee treat
• Store in a cool, dry place with the lid tightly sealed

• Those who prioritise grass-fed, naturally sourced dairy over standard grain-fed alternatives
• Gym-goers and athletes who want maximum protein per scoop without unnecessary added bulk or calories
• Anyone who values full ingredient transparency and wants to avoid proprietary blends
• Those who've found other isolates thin or unsatisfying and want a smooth, great-tasting alternative
