Experts warn consumers to check protein powder ingredients for hidden risks
Registered dietitians interviewed by The Guardian advise buyers to scrutinize whey protein labels for added sugars and artificial sweeteners after noting the US FDA does not test these supplements for safety.
FDA oversight gaps on supplements
The US Food and Drug Administration does not test the safety of protein powders. Officials also do not verify marketing claims promising improved muscle growth or recovery. This lack of regulation leaves consumers to rely on third-party certifications like NSF.
Ingredients to limit in powders
One expert suggests people may want to limit added sugars found in many blends. Others advise caution with excessive sugar alcohols such as erythritol or sorbitol if they cause digestive issues. Some consumers should also avoid artificial sweeteners that trigger their specific stomach problems.
Plant options carry lead risks
The report notes that plant-based powders carry a higher risk of containing lead compared to whey. Despite this, whey prices have surged recently while plant alternatives remain popular among buyers. Experts interviewed for the story did not recommend one type over the other universally.
