How We Tested the Best Unflavored Protein Powders

In our quest to identify the top unflavored protein powders, we employed a streamlined yet thorough testing methodology. We focused on five key criteria to ensure quality, effectiveness, and user satisfaction. Here's a brief overview of our approach:

Protein Content

We measured the protein per serving in each powder. This step was crucial to ensure that the products provided adequate protein for muscle building and recovery, aligning with daily nutritional needs.

Digestibility and Side Effects

We assessed each powder for its digestibility, paying close attention to any side effects such as bloating or gas. Products with digestive enzymes or lactose-free formulations were noted for their enhanced digestibility.

Solubility

We tested each product's mixability in various liquids using both a shaker cup and a spoon. Our goal was to ensure a smooth, clump-free experience for users.

Price per Serving

Affordability is key. We calculated the cost per serving for each protein powder to offer options that deliver good value without compromising on quality.

Third-Party Testing

To verify the purity and accuracy of product labels, we focused on powders that had undergone third-party testing. This step is essential to ensure that the products are free from contaminants and accurately represent their nutritional content.

This concise approach allowed us to effectively differentiate, rate, and rank the top unflavored protein powders, offering a trustworthy guide for consumers.
