Beta glucan and fulvic acid can be combined in a dietary supplement as a partial substitute or complete replacement for blue green algae and/or brown seaweed and its derivatives. Beta glucans are widely available as derivatives of Brewers yeast and fulvic acid is widely available as well. These supplements are not subject to the vagaries of weather-influence growing seasons as is the case with blue green algae and brown seaweed. When combined, beta glucan and fulvic acid can provide a less costly dietary supplement than blue green algae and brown seaweed and its derivatives such as fucoidan.
