Fit & Co One Whey

One Whey – Fit & Co®

Whey protein with naturally superior product properties. Exclusively available in the Netherlands from Fit & Co®.

What makes One Whey so premium?

One Whey is filtered directly from fresh milk, giving it a naturally higher content of EAAs and BCAAs, and even 14% more leucine—the most important amino acid for muscle protein synthesis—compared to "standard" whey protein derived from cheese production.

How is One Whey made?

As described above, One Whey is obtained directly from fresh milk rather than being a by-product of cheese manufacturing, as is the case with conventional whey protein.

Using a gentle, cold-processing method called microfiltration, the whey protein is separated from the other naturally occurring milk components, such as casein proteins, milk fat, and lactose.

Because our whey protein is sourced directly from milk, it undergoes fewer heating and processing steps. Most importantly, it naturally retains a superior amino acid profile compared to whey protein derived from cheese production. It contains higher levels of the amino acids most important for muscle growth, including the essential amino acids (EAAs), branched-chain amino acids (BCAAs), and leucine—the amino acids your body cannot produce on its own.

With every sip, One Whey delivers a real nutritional advantage.

A Product You Can Trust

While many manufacturers and retailers—including drugstores, supermarkets, and large online sellers—source their whey protein from multiple cheese producers that may change regularly, we work with one dedicated supplier for our ultra-premium whey protein.

When you choose Fit & Co®, you're always getting the same naturally pure whey protein, filtered directly from fresh milk.

100% Dutch. That's something you can rely on.

It Costs (Almost) Nothing Extra

Compared to standard whey protein, One Whey is a rarer ingredient. Availability can sometimes be limited, and the raw material is consistently more expensive.

Yes, you'll find cheaper whey proteins on the market—but not with the same natural product characteristics as One Whey.

We work hard every day to keep our prices and margins as low as possible. Why? Because we believe every athlete deserves the opportunity to benefit from our unique One Whey.

We're here for you.

Amazingly Delicious Flavours

Our flavours weren't created overnight.

They were developed by a Dutch company specializing in authentic Italian gelato and milkshake flavour development.

Just like our protein, we wanted our flavours to stand out—and we've succeeded. Every shake is something to look forward to, a genuine treat.
