Supplements with trademarked ingredients (R) might have unlisted substances you could be reacting to.
After a decade or so of experimenting with nutritional therapy, more and more supplements and foods began suppressing my breathing, which needless to say caused me some anxiety.
It’s not like you can power through a suffocation side effect. I did manage last year to narrow down the culprits when I finally figured out that I was reacting to calcium fillers, but that still left B6 and methylfolate.
Several readers had suggested that the MTHFR mutation might be behind health issues I’ve posted about, so if I couldn’t use methylfolate, did that mean that MTHFR was not the issue, or that it could be the issue but my liver was dying, or what?
Eventually someone reminded me of an important self-experimenting rule I have flaunted for years — try several brands of a supplement before giving up on it. The only brand of folate I’d ever used is Solgar, which contains Metafolin, an ingredient with a registered trademark (®). From the murky depths of my magnesium-stearate-addled mind, a memory struggled to the surface — don’t companies trademark ingredients so they don’t have to list them? I googled Metafolin and sure enough, I found a description of it as being about one-quarter “calcium salt and water.”
I switched to a non-trademarked, no-calcium brand of methylfolate and VOILA, my breathing actually improved. A LOT. (Which led me to believe that the other things I react to are futzing with my folate levels.)
How you go about finding ingredients of registered trademarked substances is beyond me. I lucked out with the Metafolin. I couldn’t find any info on another trademarked ingredient that came to mind, ChromeMate.
