Swanson Vitamins Quercetin – Higher Strength (60 capsules) is a supplement with a high dose of quercetin, a flavonoid found naturally in foods such as onions, apples, and berries. The form used, quercetin dihydrate, is often chosen for its stability and precise dosing. This product is suitable for those who want to supplement their intake of bioactive plant compounds and can be easily combined with other supplements as part of a personal routine.
The quercetin in this supplement comes from quercetin dihydrate. This variant is chosen for its purity, good processability during production, and the possibility of precise dosing. Quercetin dihydrate is a synthetically identical version of the flavonoid also found in plants.
Quercetin is a flavonoid found in many plant-based foods. Well-known sources include red and yellow onions, apples (especially with skin), berries such as blueberries and elderberries, grapes, capers, kale, and green tea. The amount of quercetin in foods can vary greatly depending on the type, freshness, and preparation method of the food.
Quercetin is a substance that does not naturally dissolve well in water. Taking it with a meal, especially one that contains some fat (such as nuts, seeds, avocado, or olive oil), can improve absorption in the body. Meals also ensure the supplement is processed more gradually by the body, which can help with regular absorption of the ingredients.
Quercetin dihydrate is a form of quercetin that is bound to water molecules. This means it has a slightly higher molecular weight compared to pure quercetin, but the active component remains the same. Quercetin dihydrate is commonly used in supplements because it is stable and can easily be processed into capsules or tablets. This form also ensures a consistent dose per capsule.
