Comparison of immunological properties of various bioactive combinations - Part II

Biologically active, safe and most of all natural stimulators of the immune system have been sought throughout history. Some of those, like β-glucan, are intensively studied and now, over 15,000 publications later, are being used in numerous clinical trials1 and in some countries already represent an established drug.2 However, the search for even better effects continues. Along with the testing of new natural molecules, more and more manufacturers are offering various cocktails or mixtures with potential immunostimulating properties. The main problem with these combinations is the limited research that would support the healthy claims. Individual components are often biologically active or at least have established effects on human health (in the case of vitamins and minerals), but the effects of these combinations are rarely tested. In these cases, there can be dozens of different ingredients and we have absolutely no clue if they have any synergistic activities.
