You don't know what your talking about on some of this,
Peter. My comments are mixed in below. <snip>

Quoted message said:of the consumer if they stuck to the following rules,
among others.. Unfortunately they are more usually trying
to "keep up with the Jones's"
by
Quoted message said:outdoing whatever other people are doing in the market.
1. The product would not have any unneeded herbal content.
No herbs are known to be safe or useful for long term
use in the healthy and it merely allows the seller to
charge more.
I agree that a most vitamin supplement should not have
herbs. And most don't and even when they do the doses of the
herbs are tiny. Anyway all supplements aren't just vitamins
and herbals, to frame the discussion in such a manner
betrays a hostile attitude.

2. They should not contain unneeded or possibly harmful
levels of
minerals.
Quoted message said:Iron is a definite no no in the non-anaemic. Yes. Selenium
is dangerous if taken in amounts not much more than normal
requiremnets, and should probably
only
Quoted message said:be needed in geographical areas of selenium deficiency
associated with a higher incidence of some cancers
(e,g, NZ)..
Animals studies indicate otherwise. And 200 mcg
supplementation doses are considered safe for adults. In
some area of mainland China people get rather large doses of
Se from their locally based diets without adverse events.
Quoted message said:Sodium and potassium are completely unnecessary, but may
have to be present in vitamin salts.
In the case of Na, it a case of simple reporting on the
label. Anyway, some people try to restrict their Na. And K
is limited by regulation here in the States to 99 mgs for
OTC preparations.
Quoted message said:Too little is known to justify other minerals such as
zinc, or suggest what
dose
Quoted message said:may be appropriate in a population within which most or
even all are not going to be deficient..
Many will be short on zinc. ACE inhibitors cause excessive
excretion of Zn. Higher levels of Zn reduce Cd uptake which
is a very good thing.
Quoted message said:
3. They should be marked "NOT FOR CHILDREN". Adult
preparations are dangerous in children and you should
be teaching your kids to eat better, not rely on pills.
This comment is pure horse feathers. Just look at a label
and it will say something llike the following: "Suggested
Use: As dietary supplement use One (1) softgel in
adults..........." People know to adjust doses down to lower
levels for kids.
Further,in modern lifestyles in which people are in doors
far too many (perhaps most) are short on vitamin D. With
this vitamin, adult doses are too low for optimal health
even in infants and more so in adults..
Infants and small children might get a little too much
preformed vitamin A but only slightly from an adult dose
sized tablet. Most people are aware that small children and
infants have different needs. Such authoritarian thinking
results in having bathroom heaters bearing labels advising
buyers not to use heater in the bathroom.

4. Megavitamin usage has not been reliably shown to be
safe and effective for any condition, despite the
elapse of thirty years of study.
Your eyes are closed or a best looking in the review mirror.
You pulled the 30 year number out of your hat; if you are
focused on Linus Pauling that was longer ago .....try 35 to
40 years. Nor was he the first.
Inositol is quite effective in preventing panic attacks, and
treating various OCD disorders.
Vitamin E helps slow the onset diabetic complications.
Niacin is used to lower cholesterol.
Vitamin D and K can be used in the treatment of
osteoporosis. to help slow or even halt its progression. And
I mean 10X of the AIs. Not the tiny amounts found in most
supplements.
Vitamin D supplement at 2000 IU (not a typo) in infants
prevents type 1 diabetes in kids and young adults.
Coenzyme Q can be used to slow the onset of drug
toxicity. It modestly reduce blood pressure and improve
cardiac function.
High dose folic acid helps women genetically prone to
bearing neural tube defectives not to have a repeat
experience.
Combined high dose vitamin E and niacinamide slow the
progression of type 1 diabetes.
Modest doses of b6 (5x of RDA) and Mg lower the odds of
kidneys stones.
Many elderly are B-12 short, folic acid status impaired and
getting suboptimal levels of Mg. Some of this is due to meds
and some is due to impaired digestion and absorption. Not
all of this is due to poor diet choices.
Andropausal farts and their post-menopausal buddies will
wring their hands and say 'lets study it more before we act'
which is cowardly nonsense.On many of these things it time
to go mainstream and sort it out later.
Cowardly attitudes like yours have resulted in an inadequate
folic acid program which has added too little folic acid.
Result the reduction in NTD births was only 30% not the
possible 70% the research indicated as possible. Vitamin
fortification is just vitamin supplementation of the sly.
Quoted message said:Benefits for added vitamins in studies are inconsistent,
and those that are seen
are
Quoted message said:from modest additional intake, especially if from the
diet. So a simple multivitamin with about normal
requirements and at most a little selenium might be
beneficial. I would expect most brands made in the USA by
major firms, even if cheap, would probably suffice.
And ask those who say they are selling "natural vitamins"
where they
really
Quoted message said:get their vitamins from. You may have to take more
synthetic vitamin E than of the natural isomer to get the
same effect, but the evidence also suggests you will do
even better getting it from food.
Dietary levels are likely too low to help slow the onset of
diabetic neuropathy. The evidence that food sources are
absorbed better aren't surprising as solublized forms of E
have been available since at least the early 70's and the
caution to take with the most fatty of meal of the day goes
back to at least the 60's. And anyway the reseach you refer
to if you refer to the latest research by Maret Tauber
(think I got the name right) doesn't compare vitamin E from
food (as I recall) rather it compares E fortified cereal to
a vitamin E capsule source as I recall. And the E capsules
used in the study weren't solublized.
Quoted message said:
Since big pharmaceutical companies make the vitamins that
the public has been consuming in such monumental amounts,
who on earth can you trust in this matter?
DISCLAIMER I.don't hold myself out to be any ultimate
authority on
vitamins,
Quoted message said:but suspect I have looked at more of the relevant evidence
than most of those promoting them..
You don't show signs of it. IMO
