Suggest the ideal dosage for Quercetin taken for allergy
Hasn't been established for humans yet.
I have looked into using quercetin for countering my own allergic reactions. From all of the studies I've looked at, it has shown effectiveness in vitro (in test tubes) but no dose has been established for treating allergies in humans yet. It hasn't been confirmed that it has the same effects in humans as it does in the lab.
That doesn't mean that it doesn't have potential for helping individual people. It is just still in the realm of folk medicine.
Taking 250 mg - 600 mg total per day, in divided doses (such as a maximum of 200 gm 3 x/day) is a range you may consider for hay fever type allergies. Some people believe that taking it with bromelain helps it to be absorbed or used better.
Do know that it can interact with many medications. If you are on any meds, you can let me know which ones and I can look up whether there is risk of interaction.
Regarding requesting particular doctors on this site, when you type a new question, you can write at the beginning of the first line "For Dr. Bonnie" or whomever you would like, and it will get routed accordingly. People do this all the time.
I hope this information helps. Good luck with your allergies!
From what I can find, quercetin should be ok with most H1 blockers (Benadryl, Zyrtec), and with the leukotriene receptor antagonist (Singulair). Epinephrine should be fine also.
You mention that you take H2 blockers also (Zantac, Prevacid). These stomach acid reducers can have some interaction with quercetin.
I want to correct a typo I made yesterday. I wrote that regarding a maximum dose of quercetin, no more than 200 gm 3x/day. That should read 200 mg (milligrams) 3x/day.
Have a good day.
Generally recognized as safe
This is a tough one for me to answer because I could not find human studies that were done over a long period of time. It is a supplement that is generally considered to be safe.
You can try asking our nutritionist. To do this, close the discussion with me, repost your question, and in the first line of your question write "For Nutritionist/Dietician Only Please". It will be routed to her. It may take time to get an answer as I don't see that she is on the site frequently.
