Apple cider vinegar is a fermented vinegar used for culinary and wellness routines—most commonly for digestion support and a modest improvement in post-meal blood sugar response for some people. The big rule is simple: always dilute it and protect your teeth and throat. ACV is helpful as a food tool, not a miracle cure.

Key Benefits

May support healthier post-meal blood sugar response when used with meals (supportive)
Can support digestion for some people (supportive)
Aids flavor and appetite satisfaction in low-sugar meals (supportive)
Simple pantry tool for dressings, marinades, and tonics (diluted)

Common Issues It May Help With

Blood sugar support (supportive)
Indigestion (supportive)
Cravings (supportive, appetite/meal satisfaction)

How To Use (Simple)

Dilute 1–2 tsp in a full glass of water, taken with or before meals if tolerated. Use in salad dressings and marinades. To protect teeth: drink diluted, use a straw if desired, and rinse mouth with water after.

Taste / Notes

Sharp, sour, acidic, fruity.

Evidence Level

Some human evidence supports small improvements in post-meal glucose response in certain contexts, but effects are modest and depend on the meal and individual.

Cautions

Always dilute—undiluted vinegar can irritate the throat and damage tooth enamel. Avoid if you have severe reflux, ulcers, or esophagitis. Use caution if you have low potassium or kidney disease. Stop if it causes burning pain.

Interactions

Diabetes medications/insulin (may contribute to lower glucose—monitor) Diuretics and medications that lower potassium (risk of low potassium—caution) Digoxin (low potassium risk—caution; clinician guidance recommended)
