Are protein supplements fake?

The Fitness Industry Scandal

Investigative reports in early 2026 claim many protein supplements contain far less protein than advertised, with some brands using "nitrogen spiking."

The Allegations

Nitrogen spiking: Adding cheap amino acids that test as protein but don't build muscle.

Under-dosing: Some products contain 30-40% less protein than the label claims.

Major brands implicated: Several popular supplement companies are under scrutiny.

How To Protect Yourself

Look for third-party testing certifications (NSF, Informed-Sport). Buy from reputable brands with transparency. Consider whole food protein sources. The supplement industry has limited FDA oversight, making third-party verification crucial.
