Is dihydroquercetin safe?

Dihydroquercetin (DHQ), also known as taxol, is a naturally occurring organic molecule with strong antioxidant properties. It is often extracted from plants, especially extracts from plants such as larch, which are widely used around the world. In recent years, dihydroquercetin has been increasingly used in food, medicine, agriculture and other fields due to its various biological effects, such as antioxidant, anti-cancer, and anti-radiation. However, the safety of dihydroquercetin has always been a key issue in whether the substance can be widely used. This article will discuss in detail the safety of dihydroquercetin, especially dihydroquercetin extracts.

Dihydroquercetin is one of the flavonoid compounds and is found in many plants, including grapes, lemons, oranges and larch. Among them, larch is one of the main sources for extracting dihydroquercetin. According to the process flow, dihydroquercetin is usually extracted by physical treatment, tearing, extraction, concentration, crystallization and other steps of larch roots. This physical extraction method ensures its relatively pure extract with high antioxidant activity and bioavailability.

However, there are certain differences in the composition, activity and safety of dihydroquercetin extracted from different plants. At present, only dihydroquercetin extracted from larch has passed the safety certification of authoritative agencies such as the European Union and China. According to the opinion of the European Food Safety Authority issued on February 14, 2017, dihydroquercetin extracted from larch was approved as a new food raw material and food additive. China also included the substance in the list of safe food additives in 2021.

As a natural food raw material, the safety of dihydroquercetin has been recognized by authoritative agencies in many countries. In 2017, the European Food Safety Authority conducted a detailed evaluation of dihydroquercetin extracted from larch and concluded that the extract was safe for humans at the recommended dose. In 2021, the National Health Commission of China also issued an announcement approving the legal use of dihydroquercetin as a new food ingredient.

These evaluations are based on extensive research on dihydroquercetin in animal experiments and human trials. Studies have shown that dihydroquercetin has no significant toxicity or mutagenic activity within the normal dose range and does not cause acute or long-term adverse reactions. This lays the foundation for its widespread use as a food additive and drug ingredient.

In daily life, dihydroquercetin can be taken in the form of dietary supplements, and its recommended use period is generally 3 to 6 months. During this period, taking dihydroquercetin in moderation can help resist oxidative stress, improve immunity, and help prevent the occurrence of certain diseases. Its safety mainly comes from its properties as a natural antioxidant. As one of the strongest natural antioxidants, dihydroquercetin can effectively remove free radicals in the body, thereby reducing cell damage and delaying aging.

Dihydroquercetin is not only safe, but also attracts attention for its various biological effects. Its strong antioxidant property is one of its core functions, which can protect cells from damage by free radicals and delay the aging process. In addition, dihydroquercetin also has anti-cancer potential. Studies have shown that it can inhibit cancer cell proliferation and differentiation by interfering with the signaling pathways of cancer cells, thereby playing an anti-tumor role. Its unique anti-cancer mechanism makes it a promising natural anti-cancer substance.

Dihydroquercetin also has a good hepatoprotective effect, which can protect the liver from toxins and promote liver cell regeneration. In addition, it is able to regulate blood lipid levels and prevent the development of atherosclerosis. Due to its excellent anti-radiation properties, dihydroquercetin is also widely used in radiation protection and radiation sickness treatment.

Dihydroquercetin not only performs well in the medical field, but also has a wide range of applications in food processing and agriculture. In the food industry, it is used as a natural antioxidant to extend the shelf life of food. For example, it can be used as a preservative in dairy products, meat and baked goods to prevent food from oxidative deterioration. In agriculture, dihydroquercetin can be used as an additive in animal feed to help improve livestock immunity and promote growth. It can also be used as a biostimulant for crops to enhance their resistance to diseases and adversity.

Although existing research and certification by authoritative institutions have shown that dihydroquercetin extracts are safe when used in moderation, attention should still be paid to its long-term safety monitoring. In daily life, consumers should strictly follow the relevant dosage standards, especially in dietary supplements and foods containing this ingredient, to ensure that the total intake does not exceed the recommended upper limit.

In the future, as the research on dihydroquercetin continues to deepen, its potential in preventing and treating various diseases will be further explored. At the same time, the differences in the efficacy and safety of dihydroquercetin extracts from different plant sources also need more research to verify. This will help people choose dihydroquercetin products suitable for themselves more scientifically, ensuring health while getting the maximum benefits.

In general, dihydroquercetin, as a natural antioxidant and functional ingredient, is safe when used in moderation. In particular, dihydroquercetin extracted from larch has passed safety certification from multiple authoritative organizations. However, consumers should pay attention to its source when choosing, and use it appropriately according to their personal physical condition and expert advice to ensure health. In the future, as the application of dihydroquercetin in medicine, food, and agriculture continues to expand, its safety and effectiveness will receive more recognition and attention.
