Whey Protein Isolate

Grass-fed, ultra-pure, cold-processed whey protein isolate. >90% protein by dry weight, sourced from herds never treated with recombinant bovine somatotropin (rBST) or growth hormone (rBGH). Mixes smoothly; taste is mild and clean.

ANTI Labs Whey Protein Isolate pouch
Isolate, not concentrate — which means very low lactose. For my lactose-intolerant patients who want a clinical-grade protein, WP-01 is the one.

The supplement industry's bias is toward complexity. But the clinical literature is rooted in simplicity—single compounds, validated forms, consistent doses. ANTI is grown from the literature side.

Unlike concentrate, whey isolate undergoes additional filtration to remove excess carbohydrates and lactose, leaving a cleaner, more bioavailable protein.

Frequently Asked Questions

Why isolate instead of concentrate?

Concentrate is 70–80% protein; the rest is residual lactose, fat, and milk solids. WP-01 is cross-flow microfiltered to ≥90% protein — gentler isolation that preserves bioactive peptides like lactoferrin and immunoglobulins, which ion-exchange destroys. The cleanest expression of whey, by design.

When should I take it?

Within 60 minutes post-training is the cleanest window — gets amino acids on board before your next meal. On rest days, anywhere a meal would otherwise be light on protein. Daily protein target matters more than per-shake timing.

Is it lactose-free?

Effectively yes — though trace lactose remains. Cross-flow microfiltration removes the bulk during isolation, and most people who don't tolerate concentrate or milk digest WP-01 without GI symptoms. If you have diagnosed lactose intolerance, start with a half-scoop.

How much protein should I be eating daily?

For active adults, 1.6–2.2 g/kg per day is the literature range. WP-01 delivers 25 g per scoop — for a 75 kg adult, one to two scoops typically closes the gap between food and target. A tool, not your whole protein source.

Protein dosing for older adults with sarcopenia or anabolic resistance?

Adults >65 show blunted muscle protein synthesis at standard doses; PROT-AGE consensus recommends 1.0–1.2 g/kg/day (1.2–1.5 g/kg in acute or chronic illness), distributed as 25–30 g of a leucine-rich source like whey per meal.

Why no flavors, sweeteners, or thickeners?

Every additive is a tradeoff. Sweeteners aren't universally tolerated; gums add fermentation load to the gut. Most flavoring exists to mask low-quality whey — ours doesn't need it. Protein, lecithin, nothing else. Add flavor at the blender if you want it.

Why does WP-01 contain lecithin?

For mixability. Whey isolate clumps in cold liquid without an emulsifier; lecithin breaks the surface tension so the powder disperses cleanly. We use a minimal amount (<1% of the formula), GRAS-classified, and a source of phosphatidylcholine — the precursor to choline. The one additive that earned its place.

What about grass-fed and hormone-free claims?

Yes, our cows are grass-fed and never treated with rBST or rBGH.

But honestly: for whey protein isolate, those labels are largely cosmetic. Bovine growth hormone doesn't survive pasteurization or your stomach, and the fatty-acid differences between grass-fed and grain-fed milk are filtered out during isolation. What's left is 90%+ protein — biochemically indistinguishable.

What actually matters here — purity, dose accuracy, heavy metals, microbial load — sits on every batch's third-party COA.
