One of the groups of polyphenols found in plants. It includes compounds with various structures and properties. The amount of the entire extract does not automatically provide information about the flavonoid content if the manufacturer has not provided appropriate standardization.
Characteristics and context
Flavonoids are the term for a group of compounds found in plant raw materials. The name itself does not indicate a single substance, plant or mode of action of the finished preparation. In the descriptions you can see both the general group and the name of a specific compound. It's a good idea to keep this distinction before you start collating numbers from different labels.
When the manufacturer standardizes the extract for flavonoids, check which ingredient it applies to. The amount in a serving results from the weight of the extract and the given share. Don't assume that all the plant ingredients in a mixture have the same content. If the table already declares the amount of flavonoids, do not multiply it again by the percentage given next to it.
Meaning and application
Words about cell protection or natural formula are sometimes combined with the word flavonoids. However, they do not replace data on a specific substance and formulation. Results for one compound do not describe all members of the group. Conscious choice requires separating knowledge about plant ingredients from the promises attributed to the product in advertising.
In practice
Record the plant species, part of the raw material, amount of extract and the exact standardization parameter. Also check the number of recommended servings per package. If declarations have different bases, do not compare them without further explanation from the manufacturer. Such a list is more useful than choosing the preparation with the most plant names in the title.
