Are there any supplements out there which contain only Naringenin and/or Naringin ? I get some good effects from OJ, unfortunately I also seem to have an allergy to oranges, with sneezing, runny nose, short breath... Since no other fruit juices produce the beneficial effects of orange juice, I'm assuming either naringenin or naringin could be responsible for the good effects. However, all the supplements I have seen on the market with these two flavonoids also contain something like a dozen other ingredients. Is it even possible to get them in pure powder form or something like that?
