Found this one:
"Developing a Permanent Treatment for Lactose Intolerance Using Gene Therapy"
Seems very promising. Recently, I discovered that lactase derived from Kluyveromyces lactis is effective for me, whereas lactase derived from Aspergillus oryzae seems to have little to no effect. The latter is used in mose lactase supplements
- dmart 6y agoThis is interesting. Do you know which brands are derived from each source? I wasn't able to find much information online.
- SilasHaslam 6y agoSource info is usually tucked away in fine print, or on the manufacturer's FAQ page, if at all. "Lactose-free" dairy products (milks and yogurts) and OTC supplements in pill form, as far as I know, use lactase derived from A. oryzae. Commercial dairy supply companies sell K. lactis in bulk. I've found one brand on Amazon (SeekingHealth) that's made with K. lactis derive lactose. Maybe they re-package the commercial size product? I've thought about buying a gallon for $1200, but that would probably last me more than a lifetime. Lactase comes from different sources and has different properties [0]. K. lactis has a neutral optimal pH, so it's better for processing dairy prior to consumption; A. oryzae has a lower optimal pH and higher heat tolerance, so it's more suitable for OTC supplements.
