Health benefits
- Enhances nutrient absorption by aiding the absorption of minerals like calcium, magnesium, and zinc.
- Supports energy production as a key component of the citric acid cycle (Krebs cycle), which generates energy in the body.
- Preserves food by acting as a natural preservative, extending the shelf life of various food products.
- Improves kidney health by preventing the formation of kidney stones through its alkalizing effect.
- Enhances flavor by adding a sour taste to foods and beverages, making them more palatable.
Health risks
- Potential for digestive irritation such as heartburn or stomach discomfort, particularly in individuals with sensitive stomachs or acid reflux.
- Risk of allergic reactions in some individuals, causing symptoms like itching, swelling, or difficulty breathing.
- Potential for tooth enamel erosion as citric acid is highly acidic and can weaken and erode tooth enamel over time if consumed frequently.
- Interaction with medications particularly those that affect stomach acidity, as citric acid can interfere with the absorption and effectiveness of certain drugs.
How to choose citric acid
Citric acid is often used as a preservative or to add sourness to food and drinks. Look for food-grade quality that is fine and white, without any clumps, ensuring it is pure and untainted.
Avoid citric acid that appears yellowed or has a strange odor, as these characteristics can indicate contamination or degradation. High-quality citric acid should dissolve easily and not alter the flavor of your product beyond the desired tartness.
How to store citric acid
Citric acid should be kept in an airtight container in a cool, dry place. A pantry or cupboard is perfect for maintaining its potency. Properly stored, citric acid can last indefinitely.
Exposure to moisture can cause citric acid to clump and lose effectiveness. Avoid storing it near sources of heat or humidity. Ensure the container is sealed well to prevent contamination and maintain its quality.

What to do with leftovers?
Leftover citric acid can be used in a variety of cleaning and preservation tasks. In the kitchen, it’s often used as a preservative or to add a tangy flavor to foods like jams, jellies, and beverages. Citric acid can also be used to prevent browning in cut fruits or to enhance the flavor of homemade candies.
Beyond cooking, citric acid is a powerful natural cleaner. It can be used to descale kettles, coffee makers, and dishwashers, removing lime and mineral buildup. Citric acid is also effective as a stain remover for laundry, particularly for yellowing or rust stains on clothing. Additionally, it can be used in homemade bath bombs to create the fizzing effect when they dissolve in water, making it a fun addition to your personal care routine. Citric acid can also be used to clean and disinfect surfaces in the kitchen and bathroom, thanks to its natural acidity and antimicrobial properties.
