Type O Nonsecretor with Allergies


I have been doing the BT diet now for two years. We have also recently moved from the N.E. to the Mid West. My allergies are worse off than they have been in a loooong time! I'm taking extra B vitamins, nettle, and quercitin. Is there anything else I could be doing? I am an O non-secretor.


I've found that O non-secretors with allergies often respond to anti-fungal medications. A safe and effective one is caprylic acid (a distant relative of olive oil) that is manufactured by several reputable companies. A typical does is anywhere from 500-650mg capsules taken 2 capsules three times daily.

Liver extracts (preferably 'aqueous extracted') are also quite effective for many type Os with allergies. Although known to be effective since the 1930's the rational for their action is still unknown.

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.
