Quercetin comes in many forms (including dihydrate and anhydrous quercetin), and quercetin dihydrate is another form of quercetin.
Quercetin Dihydrate is a naturally occurring flavonoid compound found in various plant-based foods. It belongs to a class of antioxidants known as flavonols, which are renowned for their health-promoting properties. Quercetin Dihydrate is particularly abundant in fruits and vegetables such as apples, onions, berries, and leafy greens.
This powerful antioxidant has gained significant attention for its potential therapeutic effects on the human body. It is known to possess anti-inflammatory, anti-cancer, and immune-boosting properties, making it a valuable addition to a healthy lifestyle.
Chemically speaking, Quercetin Dihydrate is a yellow crystalline powder that is water-soluble due to the presence of two water molecules in its structure. This unique characteristic allows for better absorption and utilization by the body, enhancing its bioavailability and effectiveness.
Quercetin Dihydrate works by neutralizing harmful free radicals in the body, which are unstable molecules that can cause cellular damage and oxidative stress. Its antioxidant properties enable it to scavenge these free radicals, reducing the risk of chronic diseases, such as cardiovascular conditions, age-related macular degeneration, and certain types of cancers.
Moreover, Quercetin Dihydrate has been linked to various health benefits, including improved cardiovascular health, enhanced immune function, reduced inflammation, and potential anti-cancer effects. Scientific studies have shown promising results, indicating that regular consumption of Quercetin Dihydrate through dietary sources or supplementation can support overall wellbeing.

Research has found that quercetin may be one of the most efficient supporters of a healthy inflammatory response. One meta-analysis of randomized-controlled trials even found quercetin supplementation helps inhibit inflammatory factors to support whole-body health.
Flavonoids all have antioxidant effects, with a clinical study finding that quercetin can positively affect markers of oxidative stress in red blood cells.
While supplements like zinc and vitamin D3 are imperative for immune support and proper nutrition, this fabulous flavonoid is not without its own benefits.
A large randomized-controlled trial was conducted on quercetin evaluating immune challenges. The trial enrolled about 1,000 people, who supplemented with 1,000 mg daily of quercetin or a placebo. After 12 weeks those over the age of 40 with higher self-rated fitness who took quercetin had significantly fewer number of days experiencing immune challenges related to the upper respiratory tract compared to placebo.
Results from a meta-analysis of 9 randomized-controlled trials showed that quercetin supplementation in dosages of 500 mg a day or more with a duration of 8 weeks or more led to significant improvements in healthy glucose levels. People under the age of 45 showed improvements in healthy insulin levels.
Multiple meta-analyses of clinical studies have demonstrated that quercetin may be a helpful tool in supporting already-healthy blood pressure levels.
Some clinical research suggests that at a dose of 500 mg or more daily, quercetin may support already-healthy triglyceride levels, but does not have a significant impact on healthy LDL and HDL cholesterol.
Perhaps one of the most interesting potential benefits of quercetin could be its senolytic properties, meaning it may help the body manage its senescent cell burden, a key component of healthy aging.
1. Dietary Supplement
Quercetin Dihydrate is commonly used as a dietary supplement due to its antioxidant properties. Many individuals incorporate it into their daily routine to support overall health and well-being. As a supplement, it is available in capsule, tablet, or powder form for convenient consumption.
2. Skincare Ingredient
Quercetin Dihydrate has also found its way into the skincare industry. Thanks to its antioxidant and anti-inflammatory properties, it is often included in various skincare products. When applied topically, it may help protect the skin from free radical damage and promote a healthy complexion.
3. Therapeutic Agent
Research suggests that Quercetin Dihydrate may have therapeutic potential for certain conditions. It has been studied for its potential anti-inflammatory, anti-cancer, and anti-allergic effects. While further research is needed, these findings highlight the possibility of Quercetin Dihydrate being used as a therapeutic agent in the future.
First things first: almost all dietary supplements that contain quercetin are found in the dihydrate form, with the main defining characteristic between quercetin and dihydrate coming down to the stability and solubility.
Quercetin exists in either a hydrous or an anhydrous state, which just means with or without water. If a compound has a hydrate, it means it contains a water molecule. “Di” means “two,” so the dihydrate form contains two water molecules. These water molecules play an important role in how quercetin reacts in the body: namely, they allow quercetin to be more stable and soluble.
Quercetin dihydrate is considered a simple and inexpensive way to get more out of your quercetin. It’s so popular and commonplace that even labels and published studies won’t always specify dihydrate, opting to simply refer to the compound as quercetin.
So, in other words, if you’re supplementing, you’re more likely than not getting the superior quercetin dihydrate form and not the anhydrous quercetin. However, it’s important to note that even though quercetin dihydrate is more stable and soluble than anhydrous quercetin, it still lacks bioavailability.
