Obtaining optimal vitamin D status will certainly help every reader.
Even if it just saves them from getting 70% fewer colds it is worth
it. The fact it also has been proved to reduce cancer incidence by 77%
is another bonus. The only way to see if your depression responds to a
safe and effective amount of Vitamin d3 is to give it a go. You can be
absolutely certain it is safe. No Observable adverse events have been
recorded under 10,000iu and no one needs to supplement at that level
anyway.

A Google Scholar search throws up

966,000 acedmic references to Vitamin D this isn't just the odd
random article. I follow the Vitamin d new research daily and it is
usually more than 5 new research papers every single day to study.

Prospects for Vitamin D NutritionVery interesting presentation
detailing the human species' need for vitamin D.
Presented by vitamin D expert Dr. Reinhold Vieth.
It's only an hour and it is more aimed at the layperson. But it sets
out the way we evolved to spend time in the sun and explains some of
the reasons why we need it so much. It is now, particularly as I've
just explained how much new research has been published, somewhat out
of date and I think Vieth would be a little more assertive than he was
when this presentation occured.

If you are near the threshold then your response will be much quicker than if you are well below optimal status. The sooner you start taking an effective amount of supplement the sooner you will begin to feel better. Taking 4000iu daily is absolutely safe it will in time raise your status to optimal.

Vitamin D is fat/oil soluble so if you can incorporate it into cod
liver oil, flax oil or something like that you stand a better chance
of it being absorbed well. I've not had any trouble taking it on an
empty stomach or with food. You could incorporate it (by sliding the
capsule apart and dropping the contents into the fat/oil you are
cooking with) into your baking, It will survive cooking so you could
easily make Cookies/biscuits with high Vitamin D3 content.

I think there are more benefits from getting it from sunlight than
from supplements. Your body was designed to absorb it this way so I
think if you can get it for free by laying near naked in the sun at
midday (when UVB<>UVA ratio optimal) for 10-20 minutes (without
allowing your skin to go red and certainly NEVER EVER BURN) regularly,
then this is certainly more effective for skin cancer prevention.

Should those of us living in the darker states

Yes
How do actually know how much to take?
Without a blood test it's impossible to know. The simplest answer is
to say that NO OBSERVABLE ADVERSE EVENTS have been reported under
10,000iu/daily so providing you never take more than that you are
unlikely to suffer adverse consequences, but you will be even less
likely to suffer adverse consequences if you stick to 4000iu as a
daily maximum intake. Bruce Hollis, whose been researching Vitamin D
for 30 yrs and who lives works in Maryland says " No one should have a
circulating 25(OH) D level-this is the metabolite that defines
nutritional vitamin D status-less than 80 nmol. I try to keep my own
level at 125 nmol minimum and consume between 2,000-8,000 IU/day
depending on the season" So anything within that range is fine.

That's true but lots of people think that providing they are outside
they will get Vit d . All Sunscreen, sunblock sun protection factor
cosmetics will stop Vitamin d production. They work by blocking UVB
without UVB there is no vitamin D3.

You do but not as much as quickly. So a brown skin will take 5 times
as long as a white skin to make the same Vitamin D3 A BLACK skin will
take TEN times as long to make the same amount so this explains why
Black skinned individuals have higher cancer diabetes incidence and
lower Vitamin d status particularly when living above latitude 45.
