Natural Flow Options+ Glass Bottle
Dr. Brown's is the only brand with a clinically proven internal vent system that reduces colic, spit-up, and gas by preventing air bubbles. The glass version eliminates any concerns regarding chemical leaching during high-heat sterilization.
Ingredients & Purity
Constructed from pharmaceutical-grade borosilicate glass. The vent system is BPA-free plastic, though it does not come into contact with the milk as much as the bottle walls do.
Scientific Evidence
Clinical studies have shown that Dr. Brown's bottles preserve milk nutrients (like Vitamins C, A, and E) better than standard bottles by reducing oxidation.
Brand Transparency
Clear labeling regarding BPA/PVC/Lead-free status; however, detailed COAs for the glass sourcing are not publicly hosted but available upon request.
Value Assessment
Excellent value when purchased in multi-packs; widely available in the US and compatible with most breast pumps.
Why Not Alternatives?
While Comotomo is easier to clean, it lacks the sophisticated vacuum-free feeding system that Dr. Brown's offers. Many plastic anti-colic bottles still utilize internal straws made of lower-grade plastics; this glass version is the safest iteration of a proven design.
