Liposomal Quercetin
Quercetin has been a favoured herb for some years and, as with all botanicals, absorbability and bioavailability is an important issue.
Many reputable brands offer herbs in phytosomal form and recently botanicals in liposomal form (the herbal extract is then encased in a fat globule) have been gaining popularity. The liposomal forms are also easy to absorb.
