Hiya is worth 3x the price for daily clean nutrition
Research-backed recommendation
The $10/month difference between Hiya and Flintstones buys you: zero artificial colors, zero artificial sweeteners, third-party testing transparency, and bioavailable nutrient forms. Even with Hiya's 7.8/10 safety score (reflecting the 2024 testing controversy), it remains dramatically safer than Flintstones' 2.5/10. Over a year, that is $120 extra for significantly cleaner daily nutrition.
