The value is the level of concentration and time for fermentation. Through trial and errors over the last 20 years, we know the concentration needs to be at least 25 time stronger than a single strength in order to make nopal work at its best. The concentration need to be done with heating, evaporation, and at least 30 days of fermentation to make the amino acids inside nopal absorb-able to human body. It's a patented process that makes nopal work at its best level, and Desert Bloom owns this patent. Desert Bloom nopal extract juice is 30 times stronger than single strength nopal juice. We see others offer nopal extract juice that is only 1.5 times stronger than single strength, we just dont' understand why they dare to call it nopal EXTRACT juice. If you have tried other nopal juice and achieve little or no result, it's not because nopal does not work; it's becasue they don't know how to make nopal work. Most nopal juices are manufacutured by an OEM manufacture that produce dozens or hundreds of products for others. Their facility and equipments are not set up to produce quality nopal extract juice. They will not set a side a large space for at least 45 days for fermentation. The cost is just too high for them. Study, ask questions before you purchase any nopal product. The level of concentration is gauranteed on Desert Bloom website, that means they are willing to back it up legally of what they claim. Desert Bloom's cost of production is extremely high compare to others, that's because we want to provide the best to the market with excellency in every way.
