How Cranberry Works
What compounds give cranberry juice its health punch?
Cranberries are packed with proanthocyanidins (PACs), vitaminC, flavonoids, and potassium. PACs stop E.coli bacteria from sticking to the urinary tract walls, while vitaminC enhances iron uptake and fights free radicals.
Why are UTIs so common during pregnancy?
Hormonal shifts relax the muscles of the urinary tract, and the growing uterus puts pressure on the bladder, creating a perfect recipe for bacteria to thrive. This is why many momstobe experience their first UTI in the first or second trimester.
How does cranberry juice help with iron absorption?
VitaminC turns nonheme iron (the kind in plant foods) from ferric (Fe) to ferrous (Fe), a form your body can absorb more easily. Pairing a glass of cranberry juice with ironrich meals or prenatal iron pills can improve the amount of iron that actually gets into your bloodstream.
