Protein bars and powders safety: experts explain third-party testing
Some people worry that protein bars and powders might not be safe to eat.
A nutritionist named Layla Al-Naif said that many of these products contain tiny bits of heavy metals, toxins, and pesticides.
She said that if the package doesn't say a product was "third-party tested," it probably wasn't tested at all.
A health expert named Anshul Singh said her worry is understandable.
He explained that ingredients like whey, soy, and rice protein can soak up tiny amounts of these substances from the soil.
But he also said that good companies do their own careful testing.
"Third-party tested" means an outside laboratory checked the product to make sure the label is correct and that there are no harmful chemicals or germs inside.
Not having that stamp does not mean a product is bad, says Singh.
Still, experts say it's best to eat real foods like eggs, milk, fish, and beans for protein most of the time, and only use bars and powders when you are busy.
Nutritionist Layla Al-Naif said on The Masoom Minawala Show that most protein powders and bars are “heavy on the heavy metals, toxins, pesticides” and are not tested unless they state they are third-party tested.
Anshul Singh, Team Lead of Clinical Nutrition & Dietetics at Artemis Hospitals, says the worry is valid because ingredients like whey, soy, pea and rice proteins may absorb trace contaminants from soil during cultivation or processing.
Third-party testing means an independent laboratory verifies ingredient accuracy and purity and checks for contaminants such as heavy metals and harmful microbes.
Singh says the absence of third-party certification does not automatically mean a product is unsafe, since many reputable manufacturers conduct rigorous in-house quality testing.
Experts advise choosing reputable brands with certifications like NSF Certified for Sport, Informed Choice, Informed Sport or USP Verified, and never replacing whole-food protein sources with bars.
