Vitamin A and B6 are critical.

This is a good site about vitamins:

Vitamin A and B6 are critical.

Vitamin D as well.
(This is just the vitamins however, minerals can also be overdosed).

That is quite theoretical. I recall that Reinhold Vieth, one of the leading
vitamin D researchers, has said that only to achieve physiological levels of
circulating vitamin D - 25(OH)D - produced by sunlight, we have to take 100
µg vitamin D. And that is far from being toxic. Personally I take 25 µgs
daily in winter time.

Vitamin D deficiency is fairly common.

Fat-soluble vitamins -- vitamins A, D, E and K build up in the fat
tissues, which means that you do not need to take them every day. If
you do take a lot daily you may end up with more in the system than is
good. You can get too much of these.

The water soluble vitamins like the B vitamins and C can be taken daily
in rather high amounts with no toxicity issues. Your body will store
some in the liver and any excess will flush out with the urine.

Yeah its also good to remember that the extent of vitamin storage can
be quite large in some cases. A healthy adult has a year's supply of
Vitamin A, Vitamin K for about 6 months. People can be overly cautious
at times.

This is not true. Long term use of high doses vitamin B6 (pyridoxine) can
cause neuropathy, which is usually reversible if the daily doses are about
250-500 mg, but irreversible, if doses are grams. Vitamin B3 (niacin) is
not harmless either: large doses can cause liver damage.

In an attempt to find all avenues to control homocysteine, I've taken doses
as high as 1000 mg/day of B6 for 3+ months without any side effects.

You have been very lucky. More than 10 years ago I developed a mild sensory
neuropathy in my feet after taking 250 mg/d for a lengthy period (I think at
least 6 months, probably over a year). Fortunately the symptoms disappeared
a few months after the discontinuation of B6. With larges doses, say 2 g/d
or more the condition is usually more severe and irreversible.
