Pure chlorogenic acid is a type of antioxidant polyphenol that is mainly found in green coffee beans, some fruits such as pears, and even some vegetables like potatoes. This acid is however mostly popular for its presence in coffee. It is a compound that has gained quite a lot of attention because of its presumably weight-loss benefits and the ability to control blood pressure.
Allocated below are some of the common types of chlorogenic acid:
CGA
Chlorogenic acid is CGA's short form. It is the most common and widely available chlorogenic acid in coffee, fruits, and vegetables. CGA is green coffee bean extracts that most dietary supplements comprise because of its potential health benefits.
Isomers of CGA
Caffeoylquinic acids are CGA's esters, which are an acid formed by the reaction between an organic acid and any alcohol, which has no carbon atoms. These acid-ester complexes comprise several isomers, including meta-chlorogenic acid and orbital chlorogenic acid, that have varying degrees of antioxidant properties.
Green coffee bean extract
GCAE contains a higher concentration of chlorogenic acid compared to regular coffee. It is mainly used as a supplement to weight loss and general well-being. It is often unfiltered and caffeine-restricted.
Coffee cherry extract
Both caffeine and caffeoylquinic acid are found in this extract, which comes from the outer pulp of the coffee cherry. Blood pressure may be potentially protected by this extract.
CgA standard
This is normally synthetically manufactured and refined to high purity concentrations. It is very common in scientific studies.
The specifications and characteristics of chlorogenic acid powder are mainly determined by its source. For instance, it is commonly found in green coffee beans and coffee fruit. However, the purity level and concentration in each supplement are determined by how it is extracted and processed.
Chlorogenic acid has multiple uses as a chemical. Some are still being studied, while others are more well-known and widely used. Below are some common uses of chlorogenic acid:
Dietary supplements: Weight loss is one of the main health benefits of chlorogenic acid. It is thought to slow down glucose absorption from the intestine and hence reduce body weight. It is often high in chlorogenic acid content green coffee bean extracts. These extracts are widely marketed as dietary supplements for weight control and management. Sometimes, supplements combine chlorogenic acid with other weight loss ingredients to boost effectiveness.
Antioxidant properties: Chlorogenic acid has high antioxidant properties and a high tendency to scavenge free radicals. This helps reduce oxidative stress in the body which can lead to chronic diseases like cancer, cardiovascular problems, and neurodegenerative diseases. It is therefore widely used in dietary supplements to promote general health and well-being and to mitigate the destructive effects of oxidative stress.
Blood sugar control: One of the most valuable properties of chlorogenic acid is its ability to control blood sugar levels. Coffee and green tea are commonly known to decrease post-meal blood sugar spikes due to their chlorogenic acid content. This helps cause the slow absorption of glucose in the bloodstream.
Weight management: Green coffee extracts that contain chlorogenic acid are widely used in weight management products. This is because it helps inhibit the absorption of carbohydrates.
Cosmetics: The antioxidant and anti-aging properties of chlorogenic acid find applications in skincare and beauty products. It helps to protect the skin from oxidative damage and may reduce the appearance of wrinkles and fine lines.
Chlorogenic acid is mainly extracted from green coffee beans and has a wide range of health benefits. To avoid the negative side effects of roasted coffee intake, most of these benefits will still be available to the user if they use chlorogenic acid.
Antioxidant properties: One of the common benefits of chlorogenic acid is its antioxidative properties. It scavenges free radicals and reduces oxidative stress, which is linked to aging and chronic diseases.
Weight management: Green coffee extracts that are rich in chlorogenic acid are widely used to support weight loss. This acid slows down glucose absorption in the gut, reducing the post-meal sugar spikes and helping the body to burn fat for energy.
Blood sugar control: Inhibition of carbohydrate absorption by chlorogenic acid helps in controlling blood sugar levels and reducing insulin resistance. This makes it suitable for people with type 2 diabetes.
Heart health: Coffee drinking populations with normal blood pressure have a lower concentration of hypertensive individuals who might find coffee to be a contributing factor. Chlorogenic acid is particularly responsible for curbing this effect It may help lower high blood pressure by blocking catecholamine receptors and allowing it to moderate norepinephrine and epinephrine activity.
Liver protection: Because of its antioxidative properties, chlorogenic acid is probably protective to the liver. It slows down the progression of liver-related diseases and conditions like fatty liver disease and liver cirrhosis.
Anti-inflammatory effects: Chlorogenic acid reduces inflammation in the body and helps bring down chronic inflammation linked to diseases like arthritis, heart disease, and certain types of cancer.
Long-term storage of chlorogenic acid extraction will allow users to enjoy the benefits over an extended period. Here are some key points on how to store chlorogenic acid properly:
Cool and dry place: Store chlorogenic acid in a cool and dry environment, away from direct sunlight and heat sources. Ideally, keep it at room temperature (15-25°C or 59-77°F). Avoid areas with high humidity, as moisture can degrade the compound and reduce its effectiveness.
Airtight container: Keep the chlorogenic acid powder in an airtight container to prevent exposure to air. Oxygen can lead to oxidation, which may degrade the compound over time. Use containers made of dark glass or opaque plastic to protect it from light exposure as well.
Refrigeration for longer storage: If storing pure caffeine for extended periods (several months), refrigeration can help maintain its stability. Ensure it is in an airtight container to prevent moisture absorption while in the fridge.
Labeling: Always label the container with the date of storage and the contents. This helps track the freshness and ensures that the most stable compounds are used first.
Avoid contamination: When accessing the stored chlorogenic acid, ensure that hands are clean and dry, or use a scoop to avoid contamination. Water, oils, or residues from hands can lead to degradation or reduced potency.
Short-term storage for extracts: Chlorogenic acid extracts from coffee beans should ideally be consumed within a few weeks if not refrigerated. If refrigerated, it can last longer, up to several months.
Yes, chlorogenic acid is generally considered safe for most individuals when consumed in moderate amounts, particularly as a component of coffee or dietary supplements.
Green coffee beans are the most concentrated source of chlorogenic acid. Other sources include coffee berries, certain fruits like pears, and some vegetables.
Chlorogenic acid is sometimes used in dietary supplements marketed for weight management. It helps reduce the absorption of carbohydrates from the digestive tract.
Usually, chlorogenic acid takes several weeks of consistent intake to manifest its effects, particularly regarding weight management and blood sugar control.
Chlorogenic acid may have some mild side effects, such as gastrointestinal discomfort, headaches, or allergic reactions. This is particularly the case when taken in high dosages or when the individual is sensitive to caffeine.
