Broad spectrum refers to a type of extract that contains a wide range of compounds from the original source, rather than isolating and concentrating just one or a few specific compounds. In the context of T-kat Ali extract, a broad-spectrum extract would aim to retain a variety of beneficial compounds naturally found in the T-kat Ali root, such as quassinoids, eurycomanone, glycoproteins, and other bioactive components.
This is in contrast to a "standardized" extract, where the focus is on isolating and concentrating one or more specific compounds to a standardized level. For example, a standardized T-kat Ali extract might specify a certain percentage of eurycomanone, one of the active compounds believed to contribute to the herb's benefits.
Both broad-spectrum and standardized extracts have their advantages depending on the desired outcomes and the specific properties one is looking for in a supplement. The choice between them often depends on the goals of the manufacturer and the preferences of consumers.
