Exclamation too much Zinc AND too mcuh B6!

Please suspend these 2 additional supplements for now:

Are you sure it is mgs - milligrams - on both those? - as opposed to %RDA or %AI (Adequate Intake).

Assuming they are in fact milligrams, as you have typed.....

=======================
on B6:
=======================

1. B6 additional supplement: The Adequate Intake (AI, formerly RDA) for B6, females 19-50 is 1.3 mg (MILLIGRAMS). did you mean 100% (PERCENT) AI? Very big safety difference. Please check the back of the bottle minutiously, noting whether it says mg or %.

100 mg with your other sources could bring you to a neurotoxic intake level. 100 mg total daily B6 is considered the uppermost tolerable limit. remember you get some in food! 1 cup of chick peas already gives you half of what you need in one day (50% AI).

2. Multivitamin supplement: Please check the %RDA or %AI (adequate intake) of the B's contained in your multivitamin. Many multivits provide 100% to what we need, or close. if it already contains ~100% (which is ~ 1.3 mg) or more of B6, that should be plenty, supplement-wise.

A caution on multivits: There are many products that are called B-100, B-50 or similar etc. They are misleading. The labeling intuitively suggests a percentage whereas the '100' actually refers to mass measure. For instance, the B-100's provide 100 mg (in some cases mcg) of each B vit. That is totally unbalanced in terms of requirements. For B6, since 100mg is the tolerability threshold, that amount is also potentially dangerous, depending on the person's diet and other supplements. Hopefully you do not have this kind.

Quote:
you can go up to 150% on the b's comfortably, as they do not accumulate.
that's percent. not milligrams. i am sorry if i was confusing going back and forth between the units and the percentage RDA.

=======================
on ZINC:
=======================

Quote:
15mg (100%) Zinc per day should be fine, even a little more (up 20ish ok). i would not exceed 30 mg so as not to upset copper balance.

the RDA/AI is 15mg. you can go up to 30 mg, but NO MORE unless, as Bizi says, you take copper too.

Wondering - does your multivitamin have any minerals in it as well? if so, which? and especially, does it have any Zinc in it? if so you need to consider that amount with any other supplements. does it include copper?

======================================

please be careful. if you want, you can type in what your various supplements have here. just be sure to copy the units correctly. then we can help do the math.
