Apple cider vinegar is often touted to ease morning sickness by supporting digestion and stabilizing blood sugar, but its high acidity can erode tooth enamel, irritate the stomach, and cause nutrient imbalances or interact with medications.

See below for complete details on risk assessment, monitoring, and safer alternative remedies.
Apple cider vinegar (ACV) has become a popular home remedy for a range of complaints, including morning sickness. You may have read about using ACV for morning sickness relief—claims of reduced nausea and better digestion. While some women share positive stories, it's crucial to understand why you should always get your doctor's approval before trying ACV during pregnancy.

Personalized Risk Assessment
Quality Control
Appropriate Dosage and Dilution
Monitoring for Side Effects

Always "speak to a doctor" about anything that could be life threatening or serious.
Your health and your baby's health are top priorities. Before starting any new remedy—including apple cider vinegar—get the green light from your healthcare provider.
