Nutricost vs. Optimum Nutrition. When it comes to choosing a whey protein powder, two names that frequently pop up are Nutricost and Optimum Nutrition (ON). Both brands enjoy strong followings and sell high volumes, but they differ meaningfully in formulation, reputation, and user experience. In this article, we’ll pit a top‐seller from Nutricost against the flagship whey from Optimum Nutrition, side by side, to help your readers decide which might be a better fit for their goals.

(Note: “top seller” here refers to Nutricost’s popular whey concentrate/isolate offerings and ON’s Gold Standard Whey, which is widely regarded as ON’s flagship whey product.)

Comparative Analysis: Key Metrics

Let’s look at how they stack up across the most relevant criteria.

Criterion	Nutricost Whey	Optimum Nutrition Gold Standard Whey
Protein per serving	~30 g (isolate version)	24 g (blend of isolate/concentrate)
Protein source / formulation	Pure isolate (in isolate version), or concentrate in other lines.	Blend (isolate first, then concentrate + hydrolysate)

Third-party / quality assurance	Nutricost claims independent testing, though details of testing laboratories are often not fully disclosed.	ON’s Gold Standard is often lauded for its reputation, distribution, and more transparent history of testing.
