How it Works

Nature’s Sunshine draws on traditional Chinese medicine in the blend of herbs that make up its KB-C, Chinese, formula. The herbs are used in Chinese medicine to support kidney and bone function; in fact, the Chinese name for the formula means “strengthen the bones.” It supports the element of water, according to Chinese philosophy. KB-C assists in promoting the health of the urinary system by eliminating water and the structural system by support the joints. It includes achyranthes and eucommia.



Eucommia bark, cistanche stem, achyranthes root, dipsacus root, drynaria rhizome, hoelen sclerotium, morinda root, rehmannia root tuber, astragalus root, cornus fruit without seeds, dioscorea rhizome, epimedium leaf, ligustrum fruit, liquidamber fruit, lycium fruit, ginseng root, tang-kuei root, atractylodes rhizome
