Grapefruit Seed Extract CapsulesPlus contain Citricidal (grapefruit seed extract), a natural quaternary compound synthesised from the seed and pulp of certified organically known grapefruit. This process converts grapefruit bioflavonoids (polyphenolics) into a very potent compound that has been found to be highly effective in supporting health, particularly for its antimicrobial activity on the gut. Grapefruit Seed Extract CapsulesPlus combines citricidal, echinacea and artemisia annua for added immune support. The formula includes the pulp, seeds and inner rind of grapefruit – all the components of grapefruit that are known to be beneficial to health – and provides a full spectrum of bioflavonoids, which are rich antioxidants. Grapefruit Seed Extract CapsulesPlus is easy to swallow and avoids any bitter or unpleasant taste. Each capsule is equal to 12-13 drops of grapefruit seed liquid extract.
