What are the side effects of Apple Cider Vinegar?

Potential side effects include: Tooth enamel erosion (if undiluted), Throat irritation, Nausea, Low potassium (at high chronic doses).

What is apple cider vinegar and how may it relate to weight management?

Apple cider vinegar (ACV) contains acetic acid, which some research suggests may influence blood sugar responses after meals and promote feelings of fullness. A small number of clinical trials have found modest effects on body weight, but the overall evidence base is limited and study quality varies.

What dosage of apple cider vinegar has been studied in clinical trials?

Clinical studies have used 15–30 mL (approximately 1–2 tablespoons) of apple cider vinegar per day, typically diluted in water and consumed before meals. Most studies lasted 8–12 weeks. Supplement capsule forms vary in acetic acid content and may not be equivalent to liquid ACV.

What are the potential side effects of apple cider vinegar?

Undiluted ACV can damage tooth enamel and irritate the throat and esophagus. Other side effects include nausea and digestive discomfort. ACV may lower potassium levels and interact with diuretics, insulin, and digoxin. Long-term use at high doses has not been well studied for safety.

About

A fermented apple product containing acetic acid that activates AMPK and delays gastric emptying. Clinical trials, including a well-known Japanese RCT, demonstrate modest support for body weight and visceral fat reduction, though effect sizes vary significantly across studies.

How It Works

Acetic acid (5-6% concentration) activates AMPK in hepatic and muscle tissue, increasing fatty acid oxidation and decreasing hepatic lipogenesis. Delays gastric emptying, reducing postprandial glucose spikes by 20-30%. Acetic acid also upregulates PPAR-alpha, promoting fatty acid oxidation genes, and may suppress lipogenic gene expression (ACC, FAS) in the liver.
