Immune Boosters in Koi and Pond Fish Food
Some foods are made with immune boosters. These are certainly harmless and they may very well perform as promised depending on what we’re talking about. Look for any combination of following putative immune-boosting ingredients like: Optimun, Aquagen, Nucleotides, Torula Yeast, Brewer’s Yeast, Bee Propolis, Colostrum, Aspergillus niger, beta carotene, lactoferrin. Don’t hang your hat on any particular ingredient as a miracle supplement or life saver – okay? …but recognize that the addition of these items represents the manufacturer as a little more attentive and knowledgeable, and the food worth a little extra money.
