These capsules contain quercetin, a plant compound naturally found in onions, apples, and berries, among other sources. Osavi uses FlaviPure, which is quercetin derived from the flowers of the Japanese pagoda tree (Sophora japonica). Each capsule provides 500 mg of quercetin, with no unnecessary additives. The capsule itself is plant-based, making it suitable for vegans. With 120 capsules per jar and one capsule per day, it lasts for four months. Pure and simple, for those who wish to supplement this specific plant compound.
Quercetin is a bioflavonoid, a group of plant compounds also known as polyphenols. You find quercetin naturally in all kinds of plant-based foods: onions (especially red), apples, berries, capers, buckwheat, and green tea. It is one of the most common bioflavonoids in our diet. The substance helps give color to plants and is often found in the peel and outer layers. In this supplement, quercetin is isolated from the flowers of the Japanese pagoda tree, one of the richest plant sources. This way, you get a fixed amount of this substance in one capsule, whereas you would otherwise have to eat a considerable amount of onions.
FlaviPure is the brand name of the quercetin used by Osavi. It is a standardized raw material, meaning that the origin and composition remain consistent per batch. Quercetin is extracted from the flower buds of Sophora japonica with an extract ratio of 12:1. In practice, this means that the 500 mg of quercetin in one capsule comes from approximately 6000 mg of flower. Because it is a standardized extract, you know exactly how much quercetin you are getting with each capsule. This is the difference from an unstandardized plant powder, where the content can vary per harvest. The Japanese pagoda tree, also known as the honey tree, has historically been known as a rich source of these types of bioflavonoids.
The amount of quercetin in food varies greatly by product and even by individual item. Red onions are among the richest sources, but even in them, it's only a few tens of milligrams per serving. Apples, berries, buckwheat, capers, and green tea provide smaller amounts. To get a consistent, higher amount, you would have to eat quite a lot of onions and fruit, and even then, the content varies by season and storage time. This is why many people choose a supplement with a fixed amount in addition to their diet. This capsule consistently delivers the same 500 mg, so you don't have to guess how much you're getting.
The formula has been deliberately kept simple. Besides quercetin, it only contains a vegetable capsule shell (HPMC) and a small amount of acacia gum as an excipient. No colorants, no unnecessary fillers. What many people don't know: quercetin naturally has a yellow color, which you sometimes see in the capsule or powder. The capsule is free from gluten, lactose, soy, and GMOs. For those who pay attention to a clean label, this is a welcome bonus. You take the capsule with some water, preferably after a meal. In short: quercetin from a plant source, 500 mg per capsule, in a jar that lasts four months.
Each capsule provides 500 mg of quercetin, extracted from approximately 6000 mg of Sophora japonica flower (extract ratio 12:1). One capsule per day is sufficient.

Quercetin is a bioflavonoid, a plant compound from the group of polyphenols. It occurs naturally in onions, apples, berries, capers, and green tea. In this product, quercetin is isolated from the flowers of the Japanese pagoda tree (Sophora japonica).
Each capsule contains 500 mg of quercetin (FlaviPure). This is due to the 12:1 extraction ratio from approximately 6000 mg of Sophora japonica flower. You take one capsule per day; the jar contains 120.
From the flower buds of Sophora japonica, the Japanese pagoda tree, one of the richest plant sources of quercetin. Osavi uses the standardised raw material FlaviPure, ensuring a consistent content per batch.
Yes. The capsule shell is made from HPMC (a plant-based material) instead of gelatin. The capsules are also free from gluten, lactose, soy, and GMO.
Bioflavonoids are a large group of plant compounds, also known as polyphenols, that give colour and flavour to many vegetables, fruits and plants. Quercetin is one of them and is among the most common in our diet. It is mainly found in the skin and outer layers of plants.
It means that twelve parts of plant material have been concentrated into one part of extract. For this quercetin, 500 mg is derived from approximately 6000 mg of Sophora japonica flower. A higher ratio means a more concentrated extract.
