In answer to your queries.
1. I refer to what beardedlady said in the
previous post. Bright yellow urine is simply
the most visible sign that you have given
your body more than it requires at that time.
The analogy most often used is that once your
car's petrol(gas) tank is full it's full and
if you keep pumping the excess will simply
spill over.(I think this analogy may even
have been used by others on this board at
times)
2. Does this place more stress on the kidneys?
Maybe, maybe not. This probably doesn't sound
helpful though I'll do my best to explain.
Unless you are taking absolute mega doses,
the B vitamins are essentially non-toxic.
The B vitamin to be most careful of would be
B6 which may cause nerve damage with
sustained high doses as mentioned in an
earlier post above by Larry Hoover( Larry is
also right that a lot of reports on B6
toxicity are anecdotal reports only though
the consensus amongst vitamin experts seems
to be that caution
needs to be taken in doses above 500mg B6 per
day though there have been isolated reports
of problems occurring from lower doses of say
above 100mg per day) I personally would not
take more than about 30-50 mg per day from
supplement sources (food sources don't cause
a problem)as I prefer to err on the side of
caution and even this amount is possibly
way more than even a highly stressed person
would require each day. (the RDA for B6 is
only about 2.2 mg per day)Also B6 MAY cause nervousness and agitation
above about 75mg per day. So therefore I
would avoid EXCESSIVE B6 before bedtime
and if you suffer from any form of anxiety.
I personally saw an improvement in my
anxiety and sleep problems when I dropped my
daily B6 supplements to below 50mg per day
and taking the supplement no later than
lunchtime. I used to believe more meant
better but I was wrong.
NOTE: you will notice that many stress
formulas and sleep formulas actually contain
B6. This is because in the right amounts B6
is actually necessary in many of the
metabolic processes that promote relaxation
and sleep. The problem occurs at high doses.
Anyway back to your question whether excess B vitamins puts extra stress on your kidneys. I think probably not at reasonable doses but then again if you keep filling your car tank after it's full the spillage may damage the paintwork.These are my views on the subject
keep well
