I don't know what ca. means
its a, i guess german, short term for describing a estimate, like ~100 or ca. 100 which mustnt be exactly 100 but could also be 90 or 110. a value based roughly around that. i dont know what the english term for this is.
But I am inexperienced with any of the following. ALA can cause problems with thiamine, or vitamin B1 deficiency. See below.
thats very interesting, greath thought, thanks.
i will directly check if this is related. though i did take a multivitamin having 10x RDA of thiamin in it. but if it gulps up the thiamin, it might be possible.
i thought it could be something which gets gulped up by ALA. maybe copper or something else.
potassium deficiency can also do numbness in fingers and legs.
though my numbness is specific to the fingers and toes, its not the whole arm and not the whole leg.
the other thing i found was IAS , autoimmune insulin syndrome where after a sulfur containing thing like ALA NAC or benfothiamine the body makes anti bodies to insulin there fore its not working anymore correctly. the symptoms are those of sugar deficiency aka hypoglycemia.
but i did not have those, just this one symptome.
You may consider discussing your reaction to it with your doctor.
there arent any doctors nowadays who even have a slight clue about biochemistry let alone vitamin interactions. if i tell this my doctor , he tells me the same like with for every supplement, that is, leave out all supplements because supplements = bad. without exceptions. of course statins and every pharmaceutical nuke is fine.
