How to choose a good whey protein
A checklist for reading any whey protein label, run against our own product like any other — including the checks it doesn't clear.
A good whey protein label answers six questions without you having to guess: how much protein it actually delivers, whether it discloses the isolate-to-concentrate split, how the dose compares to what's been studied, what else is in the tub, what you're paying per serving, and whether an independent lab has checked any of it. Here's the checklist, run against our own label like any other.
1. Is the protein-per-serving amount printed clearly?
Protein powders vary widely in both serving size and protein content, so the gram number matters more than the scoop count. Our panel states 22 g of protein per 2-scoop serving (about 35 g), 130 calories, and 2 g of sugar — printed plainly on the Supplement Facts panel, not buried in marketing copy.
2. Is the isolate-to-concentrate split disclosed?
"Whey protein isolate" and "whey protein concentrate" are genuinely different ingredients — isolate is more heavily filtered, carries less lactose and fat, and typically costs more per gram of protein. A product labeled as a "blend" of the two should, ideally, tell you the ratio, because that ratio is what you're actually buying. Ours doesn't clear this check: our panel lists "Whey Protein Blend (Whey Protein Isolate and Whey Protein Concentrate)" in the Other Ingredients statement, with a combined 22 g protein total and no split between the two components. We're stating that plainly rather than letting the word "blend" imply more than the label actually says.
3. How does the dose compare to the trials?
Acute dose-response research on whey protein has tested single doses between 10 g and 40 g: a 2014 trial found 20 g raised muscle protein synthesis significantly above a no-protein control in trained young men, and a 2016 trial found 40 g raised it further after a full-body workout. Our 22 g serving sits just above the lower end of that tested range. Those trials used whey protein isolate specifically, though, not an undisclosed isolate/concentrate blend — a gap worth knowing rather than glossing over. See how much whey protein to take a day for the full breakdown.
4. What else is in it?
Beyond the protein source, our tub contains Solnul® (Resistant Potato Starch), Natural Flavors, Pink Himalayan Crystal Salt, Guar Gum, Xanthan Gum, and Stevia Leaf Extract. The guar and xanthan gums are texturizers and contribute to the 2 g of dietary fiber on the panel; Solnul is a branded resistant starch with its own published research on gut bacteria, but our panel doesn't state how much is in a serving, so we can't and don't make a digestive claim about it. The sweetener is stevia leaf extract rather than added sugar — the 2 g of sugar on the panel comes from the dairy protein itself.
5. Allergens and diet claims
Our label states "Contains: Milk," and carries Gluten-free, Non-GMO and Vegetarian claims. It is not vegan and is not labeled lactose-free — whey is a dairy protein by definition, so neither claim would be accurate here, and we don't make either.
6. What's the price per serving?
Bottle price alone doesn't tell you what you're paying for the protein, because serving sizes and container sizes both vary between products. Ours is as low as $39.75 on a subscription for 15 servings, which works out to $2.65 a serving.
7. Has an independent lab checked it?
Third-party testing means a lab with no financial stake in the brand verifies what's actually in the tub, separate from whatever the label claims. We do not hold a third-party certification on this product, and we're not going to imply otherwise with a badge or a vague "tested" claim. If independent verification matters to you, ask any brand — including us — to show a current certificate, not just a logo.

Questions people ask
Which whey protein is best?
There's no single answer, but there is a consistent way to check any candidate: run it through the checks above. A label that states protein per serving clearly, discloses its isolate-to-concentrate split (many don't), lands close to a studied dose, discloses its other ingredients, and is priced and tested transparently has done what it can do — the rest comes down to taste and price.
What should I look for in a whey protein isolate?
An isolate-only product is a different purchase from a blend like ours: it typically carries less lactose and fat per gram of protein, usually at a higher price per serving. If a pure isolate — not a blend — is specifically what you want, check that the label says "isolate" as the sole protein source, not "blend" or "isolate and concentrate."
Are there whey protein options with no artificial sweeteners?
Check the ingredient list rather than the front-of-tub marketing. Ours is sweetened with stevia leaf extract, a plant-derived, non-artificial sweetener; other products use sucralose or acesulfame potassium, which are artificial. The ingredient list will say which.
Are there whey protein powders with added digestive enzymes?
Some products add a protease enzyme blend intended to speed digestion; ours doesn't include one. If digestive comfort is a priority for you, that's worth checking on any label rather than assuming.
Where can I buy whey protein?
Ours is available directly through our product page, including a subscription option. Shipping costs and thresholds are shown at checkout.

- The response of muscle protein synthesis following whole-body resistance exercise is greater following 40 g than 20 g of ingested whey protein In 30 trained young men, 40 g of whey after a full-body workout built muscle protein faster than 20 g did.
