Citric acid is a weak acid found naturally in citrus fruits
Citric acid is a weak acid that occurs naturally in citrus fruits, such as lemons, limes, and oranges. It is what gives these fruits their distinct acidic, tart, and sour taste. In its natural form, citric acid is an odourless and colourless compound with a crystalline structure similar to table salt. It has an acidic taste and is water-soluble, with a pH level between 2 and 6.
Citric acid is an important intermediate in metabolism, which is the process by which our bodies convert food into energy. This process occurs primarily in the liver, muscles, and kidneys. Citric acid helps our bodies derive energy from carbohydrates, fats, and proteins. It also enhances the bioavailability of minerals, allowing for better absorption by the body.
Citric acid is commonly used as a food additive for natural flavouring and as a preservative. It is added to canned and jarred foods to prevent botulism, a serious illness caused by the Clostridium botulinum bacterium. Citric acid is also used in cosmetics and personal care products for skin brightening, correcting dark spots, and minimizing fine lines. Additionally, it is a component in cleaning products due to its antimicrobial properties.
While natural citric acid is generally safe for consumption, some individuals may have allergies or intolerances to synthetic versions of citric acid, which are produced from black mould (Aspergillus niger). These synthetic forms are commonly used as additives in processed foods, beverages, and supplements. In rare cases, they have been linked to adverse reactions, including severe joint and muscle pain, abdominal bloating, and gastrointestinal issues.

It is a common additive in food, beverages, medicines, and supplements
Citric acid is a weak acid that occurs naturally in citrus fruits and other produce. It is a common additive in food, beverages, medicines, and supplements, as well as in cleaning and cosmetic products.
In the food and beverage industry, citric acid is used as a flavouring and preservative agent. It is added to canned and jarred foods to prevent botulism and to extend the shelf life of fresh produce. Citric acid is also used to enhance the acidity of certain products and balance pH levels. It is commonly found in sodas, juices, powdered beverages, candies, frozen foods, dairy products, and canned fruits and vegetables.
In the pharmaceutical industry, citric acid is used to stabilise and preserve active ingredients in medicines. It is added to enhance or mask the taste of chewable and syrup-based medications. Citric acid is also used to treat health issues such as kidney stones and blood clots.
Citric acid is added to supplements to enhance the bioavailability of minerals, allowing the body to absorb them more effectively.
While citric acid is generally safe for consumption, the synthetic version, manufactured using black mould (*Aspergillus niger*), can cause adverse reactions in some individuals. These reactions may include digestive issues and inflammatory responses, particularly in people with mould allergies.

Citric acid has antimicrobial and preservative properties
Citric acid is a weak acid with antimicrobial properties. It is an organic compound that occurs naturally in citrus fruits, such as oranges, lemons, and limes, giving them their characteristic sour taste. The antimicrobial activity of citric acid is influenced by its concentration and the pH of the environment. At higher pH levels, the fully ionized form of citric acid has been found to be highly effective in destroying certain bacteria, such as Escherichia coli and Klebsiella aerogenes.
Citric acid has the ability to slow down the growth of microorganisms like bacteria, yeast, mould, and fungus, making it an excellent preservative. This property is utilized in the food industry to prevent spoilage and prolong the shelf life of various products, including canned foods. Citric acid is commonly added to canned fruits and vegetables to protect against botulism, a serious illness caused by the Clostridium botulinum bacterium.
In addition to its antimicrobial properties, citric acid is also used as a preservative in cosmetics and personal care products. It helps to preserve the colour and fragrance of toiletries and perfumes. Citric acid is also incorporated into face creams and makeup due to its ability to clear skin infections. In soaps, shampoos, and rising agents, citric acid acts as a pH adjuster, clarifying agent, and water softener.
Citric acid is generally considered safe for human consumption and is favoured by manufacturers for its preservative qualities. It is a natural preservative without harsh chemicals, helping to keep food fresh and prevent foodborne illnesses. Citric acid is also used in medicines to kill bacteria and lower acid levels in the urine, making it a component in some kidney medications.
While citric acid is beneficial for preservation and antimicrobial purposes, excessive consumption may have adverse effects on the teeth, stomach, and skin. It is important to note that while natural citric acid is safe, manufactured citric acid produced from Aspergillus niger, a type of black mould, has been associated with allergic reactions and increased inflammation in some individuals.

It may have health benefits, but adverse effects are also possible
Citric acid is a weak acid that occurs naturally in citrus fruits and other foods. It is also produced in a synthetic form derived from black mold, which is added to many processed and packaged foods, drinks, and cleaning products.
Citric acid has many health benefits. It is an antioxidant, helping to counter inflammation and cell damage. It can also help the body absorb nutrients and transform food into energy. Citric acid is also used to treat kidney stones and blood clots.
However, adverse effects are also possible. Synthetic citric acid may cause allergic reactions in people with mold allergies. Some people may also be allergic or intolerant to synthetic citric acid, leading to digestive issues and inflammatory responses. In one case study, a patient reported developing severe joint and muscle pain, abdominal bloating, and cramping within 6-12 hours of ingesting foods containing synthetic citric acid. The severity of symptoms correlated with the amount of synthetic citric acid consumed.
Citric acid may also negatively impact the teeth, stomach, and skin. It can affect blood sugar levels, although studies have found conflicting results. If you have concerns about high blood sugar or other health issues related to citric acid consumption, it is important to consult a healthcare professional.

Synthetic citric acid may cause allergic reactions in some people
Citric acid is a weak acid that occurs naturally in all citrus fruits. It is colourless and odourless, giving fruits like oranges, lemons, limes, and grapefruits their characteristic tart, sour taste. It is also found in lower quantities in other fruits and vegetables, such as pineapples, strawberries, tomatoes, and peppers.
Citric acid is an important intermediate in metabolism, the process by which our bodies convert food into energy. It also enhances the bioavailability of minerals, allowing our bodies to absorb them more efficiently.
Synthetic citric acid, on the other hand, is produced from black mould, specifically Aspergillus niger, which creates citric acid when fed sugar. This mould is a known allergen, proven to cause allergic reactions and diseases in humans. Despite this, synthetic citric acid has been granted GRAS (Generally Recognised as Safe) status by the FDA without any research to substantiate this claim.
Synthetic citric acid is commonly used as a food additive to boost acidity, enhance flavour, and preserve ingredients. It is estimated that food and beverages utilise 70% of manufactured citric acid, with the remaining 30% used in pharmaceuticals, dietary supplements, cleaning agents, and cosmetics.
Due to its widespread use, it is imperative to ascertain the safety of synthetic citric acid, especially for individuals with allergies or sensitivities. Case reports have indicated that ingestion of synthetic citric acid may lead to increased inflammation in susceptible individuals, affecting the respiratory, gastrointestinal, neurological, and musculoskeletal systems. Symptoms may include joint pain and swelling, muscular pain, abdominal cramping, and fatigue. These symptoms typically manifest within 6-12 hours of exposure and resolve within 72 hours.
