TL;DR
- The FDA does not test protein powders for safety or marketing claims.
- Ingredients to potentially limit include added sugars, excessive sugar alcohols, and artificial sweeteners.
- Avoid "proprietary blends" and products with excessive vitamin/mineral fortification unless needed.
- Third-party certifications (NSF Certified for Sport, Informed Sport, USP Verified) confirm product content and test for contaminants and banned substances.
- Organic whey is a personal preference and not necessarily better or more nutritious than non-organic whey; prioritize third-party certification.
- Consuming too much protein powder can overload the liver and kidneys.
- Adequate water intake is crucial when using protein powder, especially if used as fuel.
