Why Protein Powder Prices Vary

Many people assume that expensive protein powders are significantly better than cheaper alternatives.

In reality, the biggest factors affecting price are:

• Product size

Most mainstream whey protein products provide similar amounts of protein per serving.

This means budget-conscious shoppers can often save money without sacrificing results.
