Last updated: 11 October 2026
Sea buckthorn juice and apple cider vinegar are generally well tolerated by healthy adults in small, diluted servings, but both are acidic and tart. Possible problems include heartburn, stomach upset and tooth sensitivity, and people with ulcers, reflux, low blood pressure or kidney disease should check with a doctor first.
Shared precautions
- Acidity: both can irritate the stomach and throat if taken strong or on an empty stomach.
- Teeth: frequent acidic drinks can wear enamel. Rinse your mouth with water afterwards.
- Dilution: always mix with a full glass of water.
- Quantity: keep to the suggested servings, 15 ml of each at most (10 ml for sea buckthorn if you are new).
Specific to apple cider vinegar
Avoid undiluted use. The label advises against use in ulcer, low blood pressure and kidney disease unless advised by a healthcare professional. Some diabetes medicines and diuretics may interact with vinegar.
Specific to sea buckthorn juice
Sea buckthorn is a fruit juice and also tart. If you take blood-thinning medicines, have bleeding issues, are due for surgery, or are pregnant, speak to your doctor before using it, because concentrated plant products can matter in these situations. Mevva's juice contains 0.1% food-grade sodium benzoate as a preservative.
