Supplements and Medications to Avoid on the Low Oxalate Diet

Some of these are to be avoided because they can contribute to an oxalate problems. Others are to be avoided only in some specific cases. Read on to learn more…

Substances Which May Cause Oxalate Production in the Body

Vitamin C: This should be avoided primarily because it can be metabolized to oxalate. Note that this will not necessarily be an observable phenomenon, as the effect may be delayed by as much as two weeks. For this reason, many folks prefer to get their Vitamin C from their diet alone. It is recommended that if you must supplement, that you not exceed 250mg per day.

PEG (Polyethylene Glycol) compounds like Glycolax or Miralax: These may be converted with the help of microbes into oxalate. Especially discontinue if you see symptoms, or if your symptoms began shortly after you started one of these.

I have also noticed that an alarming number of supplements have PEG in theme as an ingredient. While it presumably occurs only in tiny amounts in this case, I do my best to read labels and avoid it whenever possible.

Substances Whose Absorption May be Affected by the Low Oxalate Diet

In truth, leaky gut is a problem for many if not most individuals who need the LOD. For this reason, the efficacy of almost any substance could be noticeably altered by the gut healing that occurs on LOD. However, these substances are some which have specifically been mentioned on the Trying Low Oxalates group.

Iron: Some have seen improvements in iron status on diet, but it may be needed at the beginning.

Fish oils: If there is poor fat digestion, this may cause more absorption of oxalate. Try the diet both with and without to see which is better. In addition, the vitamin D in some fish oils may be a problem for some children.

Nystatin: This may possibly keep the gut leaky through effects on the membrane that lies at the at the tight junction. Try eliminating it and see if that works better.

Other supplements or medicines: If already take supplements or medicines, be sure to check these against the list of supplements which have been tested for oxalates. Also, if your supplement contains an ingredient which shows up as high (for example, beet root powder or powdered spinach), be wary of that as well. Some supplements have only tiny amounts of these high-oxalate ingredients, whereas others are high enough to count as an infraction all by themselves. The only way to know is to have it tested.

Also note: Needs for supplements and medications tend to change on this diet; sometimes rapidly so! Many find that they are able to eliminate parts of their supplement program gradually, including anti-yeast strategies. Others find their gut heals so well that they no longer require gastrointestinal medications. Work this out with the help of your or your child’s doctor.
