A sensible amount of apple cider vinegar is about 15 ml (one tablespoon) a day, diluted in a full glass of water. Beginners can start with 5 to 10 ml. There is no proven benefit in taking more, and larger amounts raise the chance of throat, stomach and tooth problems.
The simple rule
- Starting out: 5 to 10 ml in a glass of water, once a day.
- Usual serving: about 15 ml (one tablespoon) in a 250 ml glass of water, once a day.
- Ceiling: do not take it undiluted, and do not take several servings a day just because it feels easy to.
Why not take more?
Apple cider vinegar is acidic. Higher amounts have been linked in case reports to throat irritation, stomach upset and enamel erosion. Research on benefits is limited, and studies that did find small effects used modest daily amounts, not large ones. More is not better, and it can be worse.
How to measure it
Use a measuring spoon or a small cup with ml markings. One tablespoon is roughly 15 ml. A 250 ml bottle of Mevva Apple Cider Vinegar gives about 16 servings at 15 ml, so a bottle lasts a little over two weeks.
How to build up
- Days 1 to 3: 5 ml in a full glass of water.
- Days 4 to 7: 10 ml.
- From week two: 15 ml if it feels comfortable.
If you feel heartburn, nausea or a sore throat at any point, stop and reduce the amount. If it keeps happening, stop altogether and speak to your doctor.
Does body size or age change the amount?
The same general guidance applies to most healthy adults, but children, pregnant women and people with medical conditions should speak to a doctor before using it. Mevva's label advises against use during ulcer, low blood pressure or kidney disease unless advised by a healthcare professional.
Can I spread it through the day?
You can split the 15 ml into two smaller servings in two glasses of water, for example one in the morning and one in the evening. Keep the total at about 15 ml for the day.
