Brands like Gaia Herbs (Trust Score 85/100, third-party tested) and NOW Foods (Trust Score 78/100, third-party tested) have higher scores due to their commitment to third-party testing and certifications. Other brands such as Nature's Bounty (Trust Score 40/100) have lower scores due to similar transparency concerns.
