What Foods Contain Taxifolin
Taxifolin powder is an essential natural antioxidant necessary for the human body. Dihydroquercetin is a rare and extremely valuable pharmaceutical and health food ingredient worldwide. Presently, it is only found in yew, yellow fir, and larch, and there is also a minimal amount in the mother tree and wild black cherry.
Apples are found in the skin of apples, especially in varieties with darker pigmentation.
Onions: Red onions, mainly, are a good source of dihydroquercetin.
Buckwheat: This whole grain is a rich source of dihydroquercetin. Buckwheat groats, flour, and noodles are all excellent options.
Green tea: It is present in green tea, contributing to its antioxidant properties.
Red wine and grapes: Red wine and grapes, especially those with darker skin, contain it.
Cacao and dark chocolate: Cacao beans and dark chocolate are known to contain it, but the content can vary depending on the processing.
Citrus fruits: Oranges, lemons, and grapefruits are some fruits that contain them in varying amounts.
Capers: Capers contain the edible flower buds of the caper bush.

What Is Dihydroquercetin Used For
Dihydroquercetin has a wide range of applications, which can be summarized into four main aspects:
One is the food processing industry: using its super antioxidant and biological activity as a food additive can extend the validity period of food by 2-3 times;
The second is the medical and health products industry: used to manufacture and treat high blood pressure, delay aging and genetic abnormalities, resist radiation, improve immunity, and inhibit the function of diseased cells;
The third is industry: Dihydroquercetin exceeds many known antioxidants in use, such as anti-vibration agents for engines and jet rocket materials, stabilizers for rocket and hydrocarbon materials, and antioxidants for pigments and paints.
Fourth, agriculture and forestry: "Plant growth regulators" that use taxifolin extraction waste as the primary raw material can reduce the impact of bacteria and fungi on plant germination, growth, and fruiting stages, enhance their cold resistance, drought and storage properties, and improve the quality of crops. It can also be used for seedling cultivation in forestry systems to improve seedlings' quality and the afforestation's survival rate.

Taxifolin VS Quercetin
Taxifolin and quercetin are flavonoids belonging to the same class of compounds. While they share some similarities, there are differences between dihydroquercetin and quercetin:
Chemical Structure: Dihydroquercetin, is a flavanonol, while quercetin is a flavonol. The main structural difference is its additional hydrogen atoms, resulting in its dihydro form.
Occurrence in Nature: Dihydroquercetin is found in various plant-based foods such as apples, onions, buckwheat, and green tea. On the other hand, quercetin is more widely distributed and can be found in foods like onions, capers, citrus fruits, leafy greens, and berries.
Antioxidant Activity: Both dihydroquercetin and quercetin exhibit strong antioxidant properties, helping to neutralize free radicals and reduce oxidative stress in the body.
Bioavailability: Dihydroquercetin has been suggested to have higher bioavailability than quercetin, meaning it may be more easily absorbed and utilized by the body.
Supplement Availability: Both taxifolin and quercetin are available as dietary supplements. However, taxifolin supplements are less common compared to quercetin supplements.

Dihydroquercetin Side Effects
The safety of DHQ is relatively well-studied. Toxic effects from overdoses in men have not been reported in the literature, presumably because they have not been observed. Based on the available information, the side effects of dihydroquercetin are not well-documented. It is considered to have a low toxicity profile. When eaten in large quantities, some people may occasionally have moderate gastrointestinal symptoms such as nausea, diarrhea, or stomach distress. If you experience any unexpected or concerning symptoms after taking dihydroquercetin, it is advisable to discontinue use and consult a healthcare professional promptly.
