Quercetin Dihydrate vs Quercetin Anhydrous vs Quercetin Phytosome: What are the Differences?
Quercetin is a type of flavonoid present in many fruits, vegetables, and grains. It’s one of the most abundant antioxidants in the diet and plays an important role in helping your body combat free radical damage, which is linked to chronic diseases. In addition, its antioxidant properties may help reduce inflammation, allergy symptoms, and blood pressure.
Some doctors are advocating its use against SARS-CoV-2 (COVID-19), in combination with vitamin C, noting that Quercetin and Vitamin C have synergistic effects.
Quercetin supplements come in different forms. There are many quercetin forms available out there. Which one is better and which one should you buy?
Quercetin phytosome vs Quercetin dihydrate
That’s why the supplements may include other compounds, such as vitamin C or digestive enzymes like bromelain, as they may increase absorption.
Additionally, some research indicates that quercetin has a synergistic effect when combined with other flavonoid supplements, such as resveratrol, genistein, and catechins.
Most in vitro studies used a form of quercetin called ‘quercetin aglycone’. However, this particular form of quercetin is never found in the blood, even after ingested, as it it gets changed in the liver.
Quercetin Anhydrous vs Quercetin Dihydrate
Most of the quercetin ingredients on the market are in the quercetin dihydrate form. Quercetin anhydrous and dihydrate differ in the amount of water they contain. Quercetin anhydrous contains only 1% to 4% moisture and the sugar molecules that are attached to quercetin in its natural form have been extracted. This translates into 13% more quercetin per gram for quercetin anhydrous vs quercetin dihydrate. For formula manufacturers, this means there is substantially less bulk per capsule or tablet.
Quercetin Dihydrate vs Quercetin
The key difference between quercetin and quercetin dihydrate is that quercetin is a plant flavonoid, whereas quercetin dihydrate is a synthetic chemical compound. Moreover, quercetin is a yellow crystalline powder, whereas quercetin dihydrate is a bright yellow colour powder.
