Thanks ... I was thinking it might help with immunity, energy and vitality. I'll probably 'give them a go' and see if I notice anything. Or perhaps taking beta glucans would be a more direct approach.
Beta glucans are simply immune stimulating polysaccharides with a fancy name so they can make it sound exotic and charge more. You can obtain beta glucans from nutritional yeast and oats to name a few. And other immune stimulating polysaccharides can be found in numerous plants such as seaweeds, most mushrooms, myrrh, astragalus, aloe, echinacea, birch, etc.
