What to Avoid

Proprietary Protein Blends

Some products list “proprietary protein blend” without disclosing amounts of each protein type. This lack of transparency makes it impossible to assess quality or value.

Excessive Sugar

Some “protein shakes” contain 20-30g sugar, essentially making them protein-enhanced milkshakes rather than serious nutrition products. Check nutrition facts carefully.

Unrealistic Marketing Claims

Be skeptical of claims about dramatic muscle gains, extreme weight loss, or proprietary formulas that supposedly outperform standard protein. Quality protein works through providing amino acids, not marketing magic.

Amino Acid Spiking

Some manufacturers add cheap individual amino acids to inflate apparent protein content without providing complete protein. Third-party testing helps identify products with accurate protein claims.
