Protein bars and powders: How to choose safer products and what ‘third-party tested’ means

Concerns have been raised about the safety of popular protein bars and powders. Nutritionist Layla Al-Naif expressed worry about heavy metals, toxins and pesticides found in many protein supplements, which are often not independently tested. According to Anshul Singh, Team Lead at Artemis Hospitals, while manufacturers do typically test their products, third-party testing provides an extra layer of assurance.

Third-party testing involves an independent lab checking the product's accuracy, purity and absence of contaminants. However, the lack of third-party certification doesn't necessarily indicate poor quality or safety; many reputable manufacturers also conduct thorough in-house testing. Protein bars can be a convenient option during busy times or after workouts, but they should not replace whole foods.

Singh advises choosing products from transparent brands with independent certifications, minimal added sugars, no artificial additives, and proper packaging. Checking nutrition labels, reviews and asking about manufacturing dates can also help consumers make safer choices.
