Immune-stimulatory compositions and methods of manufacture are described with an unexpectedly greater immunostimulatory effect on the immune system than the individual components alone. The compositions include a combination of arabinogalactan protein (AGP) compounds, particularly those derived from honey or with similar activity to honey derived AGP's along with apisimin proteins, peptides or functional fragments thereof, particularly those isolated from royal jelly or apisimin produced via recombinant methods.
