Overview
Apple cider vinegar (ACV) is made by fermenting crushed apples through a two-stage process: first converting sugars to alcohol (by yeast), then to acetic acid (by bacteria). Raw, unfiltered ACV contains the "mother" — a colony of beneficial bacteria, enzymes, and proteins. ACV has been used as a folk remedy for thousands of years and has gained significant modern popularity. Its primary active compound, acetic acid, has documented effects on blood sugar regulation, antimicrobial activity, and digestive health.
Traditional Use
Apple cider vinegar has been used medicinally for over 2,000 years. Hippocrates (460-370 BC) used vinegar mixed with honey (oxymel) to treat coughs and colds. Ancient Babylonians used vinegar as a preservative and condiment. During the American Civil War, ACV was used to treat wounds and prevent scurvy. Folk medicine traditions across Europe and America have used ACV for everything from weight loss and digestive complaints to skin conditions and sore throats.
Key Active Compounds
Acetic Acid (5-6%)
The primary active compound responsible for most of ACV's therapeutic effects. Inhibits digestive enzymes that break down starch, slowing glucose absorption. Has antimicrobial properties and may support weight management.
The "Mother" (Acetobacter bacteria)
A colony of beneficial bacteria, enzymes, and proteins in raw unfiltered ACV. May provide probiotic-like benefits for gut health.
Polyphenols (Chlorogenic Acid)
Antioxidant compounds from the apples that provide anti-inflammatory and cardiovascular-protective effects.
Organic Acids (Malic Acid, Citric Acid)
Contribute to ACV's sour taste and may support energy metabolism and digestive health.
Evidence-Based Benefits
Blood sugar regulation
Moderate evidenceMultiple clinical trials show ACV taken before or with meals significantly reduces post-meal blood glucose spikes by 20-34% in both healthy individuals and type 2 diabetics. Acetic acid inhibits starch-digesting enzymes.
Antimicrobial activity
Moderate evidenceAcetic acid has broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses. Used topically for skin infections, nail fungus, and as a natural food preservative.
Weight management support
Some studiesA 12-week Japanese clinical trial showed daily ACV consumption reduced body weight, BMI, visceral fat, and waist circumference compared to placebo, likely through appetite suppression and improved fat metabolism.
Digestive support
Traditional useACV may stimulate digestive enzyme production and stomach acid, supporting digestion of proteins and fats. Traditionally used for heartburn, bloating, and indigestion.
Common Preparation Methods
ACV Tonic Drink
Mix 1-2 tablespoons of raw, unfiltered ACV in 8 oz of water. Add honey and lemon to taste. Drink before meals.
Dosage: 1-2 tablespoons in water, 1-3 times daily before mealsALWAYS dilute — never drink undiluted ACV. Use a straw to protect tooth enamel.
Salad Dressing
Use ACV as the acid component in salad dressings: 2 tablespoons ACV, 3 tablespoons olive oil, herbs, and honey.
Dosage: 1-2 tablespoons daily in foodConvenient way to incorporate ACV into daily diet.
Topical Application
Dilute ACV 1:1 with water. Apply to skin conditions (acne, fungal infections, sunburn) with a cotton ball. Leave for 5-10 minutes, then rinse.
Dosage: Apply 1-2 times dailyAlways dilute before applying to skin. Patch test first. Avoid on broken skin.
Safety & Cautions
Please read carefully before use
Contraindications
- Tooth enamel erosion: always dilute and use a straw

Possible Side Effects
- Tooth enamel erosion with undiluted or excessive use
- Throat irritation if undiluted
- Digestive upset at high doses
- Low potassium with excessive long-term use
Special Populations
- Pregnancy: safe in food amounts; avoid large medicinal doses
