ACV Pre-Meal Glucose Tonic
Acetic acid to blunt the post-meal blood sugar spike

About this remedy
Apple cider vinegar's acetic acid slows gastric emptying and inhibits certain digestive enzymes, which together blunt the post-meal blood sugar spike. A 2004 Diabetes Care study found 2 tbsp ACV before a high-carb meal reduced post-meal glucose by 34% in people with insulin resistance, and similar-sized studies since have replicated the effect. Distinct from the existing ACV Morning Tonic — this one is timed pre-meal specifically for glucose control, not general wellness or weight.
Preparation
Mix 1–2 tablespoons (15–30 ml) raw unfiltered apple cider vinegar into 8 oz (240 ml) of water. Add a squeeze of lemon to brighten the flavour. Drink 15–20 minutes before a carb-heavy meal.
Dosage
1 dose before your largest carb-containing meal of the day
Cautions
Always dilute — undiluted ACV can damage tooth enamel and irritate the esophagus. May interact with diuretics, insulin, and diabetes medications — monitor blood sugar. Not recommended for those with gastroparesis (delayed gastric emptying is undesirable).
