Jessica,
My apologies on not seeing this post. These computer systems are complicated with a lot of moving parts and sometimes postings don’t transfer over.
The oxalate is probably yeast related and diet. However, not a bad idea to cut back on Vitamin C dosing to no more than 400mg daily. Focus on diet and yeast treatment and I would personally add in Cal/Mag Citrate with meals and VSL#3 (one capsule) at bedtime.
The glutathione markers look okay, so the Citric may be related to intake as well. I like the idea of heavy metal testing to be sure so I would suggest doing a Hair Metals Analysis either from Great Plains or Doctors Data.
Sincerely,
Dr. Woeller
