Where do vegans like me get our vitamin
D? Well, from the sun, of course. I mean c’mon.
-
Can’t you tell? Can you? Probably not…
-
Hi it’s Emily from Bite Size Vegan and welcome
to another vegan nugget. Vitamin D is of course
-
associate with the sun, but with estimates
of around 70% of the population being deficient,
-
we’re apparently not getting the exposure
we require. Now this is an oversimplification
-
of the matter as vitamin D comes in two basic
forms: D2 and D3. D2 is present in vegetables
-
and various supplements and D3 is mainly formed
from our skin’s exposure to the sun.
-
But is also present in a variety of animal products,
like fatty fish and their oils, beef liver,
-
egg yolks, and fortified dairy and grain products.
The fortified products, however, have marginal
-
levels for the most part, and are not well
regulated. So what’s a vegan, particularly
-
a vegan in non-tropical climates, to do? Well,
in this fifth video in my nutrient series
-
with nutrition powerhouse Dr. Michael Greger
of Nutritionfacts.org,
-
We’ll tackled the vitamin D debacle.
-
Could you talk a little bit about Vitamin-D
in, you know, a plant based diet. Where are
-
we getting it...Is it beyond just exposing
yourself to the sun and how does all of that work?
-
So, Vitamin-D is the sunshine
vitamin. It’s actually not a vitamin but
-
a hormone...our skin makes when it’s exposed
to sunlight. Of course, depends on where you
-
live on the planet. We evolved running around,
you know, naked in equatorial Africa getting
-
baked in the sun all day. We just weren’t
meant to live at such latitudes where during
-
the winter months, up in Boston for example,
January, February, no matter how much you
-
sunbathe naked on the commons, you are not
going to make enough Vitamin-D. Now, there
-
are some Vitamin-D you made in the summer
that will be stored in your fat, and so you...
-
...but your levels will dip below which we believe
is optimal. So, particularly during the winter
-
months or anytime during the year for people
not getting enough mid-day sun, and for white
-
enough people at low enough latitudes, you
know, 5 minutes forearms and face...
-
...can be enough mid-day sun. But, particularly at higher
latitudes with darker skin, people that are
-
older, or those that have jobs and they’re
inside all day, no matter how sunny it is
-
outside, should get their Vitamin-D from Vitamin-D
supplements. So, I recommend for people not
-
getting enough mid-day sun to take...2,000
International Units (IU) of Vitamin-D a day which is what I do.
-
Do you know, are there any Vitamin-D
supplements that you are aware of that don’t
-
have their source from Lanolin or any sheep
sources?
-
Oh yeah, so all D2 sources come
from fungi; from mushrooms, and there are
-
now plant based sources of D3 which are made
from lichen. And the studies showing that
-
Vitamin-D, optimal Vitamin-D levels associated
with longer life have come from Vitamin-D3
-
studies, so I encourage people, eh...that
D3 is better just because we have data there.
-
So, you can get plant based or animal based
D3 just as easily.
-
I hope you enjoyed hearing from Dr. Greger
on this matter. Just to note, Vitamin D is
-
essential for bone health as it helps calcium
get from our intestines to our bones.
-
You can find out all about calcium in a vegan
diet in this video. It also helps with muscle
-
function and is associated with lower risks
of breast and colon cancer. Vitamin D may
-
also play a role in mood stabilization and
fighting depression.
-
As Dr. Greger said, depending on where your
live, and even your body’s individual absorption
-
issues, you may not be getting adequate vitamin
D, regardless of your diet. We were intended
-
to get our D from the sun but as most of us
are no longer running around naked in the
-
tropical sun and feeling the rays lap our skin
with their warm embrace.
-
Well, this is...awkward.
-
There are areas of the world where sun-based
vitamin D is simply not available for long
-
stretches of time. Dietarally, there now exists
UV-exposed mushrooms that contain vitamin D
-
Mushrooms naturally produce and store the
vitamin when exposed to sunlight, but don’t
-
tend to grow in sunlight, so farmers have
taken to briefly exposing harvested mushrooms
-
to UV light. This can also be accomplished
by leaving them in the sun, however then...
-
...they shrivel up.
-
Eww!
-
No..Eww!
-
So, if you want to supplement, how do you
ensure the sources are vegan? Well, D2 is
-
always vegan, as it’s a plant-based source,
but D3, which is commonly used in supplements
-
and vitamin D fortified grains, juices, and
other products, comes from lanolin, which
-
is derived from sheep’s wool.
-
Now if you’re thinking “what’s the big
deal? It’s not like sheep are dying for
-
their wool". Please see my video on whether
wool is vegan. Up until more recent years,
-
there were no vegan vitamin D3 supplements.
However, now there are several brands of vegan
-
D3 on the market, derived from lichen.
-
I have links to the vegan D3 supplements and further
reading in the blog post for this video, which
-
is linked in the video description below and in
the infocard sidebar. Now I personally don’t eat any
-
fortified foods so when I enter my food intake into Cronometer,
-
my vitamin D always looks,
kind of sad. But, I am sure to expose myself
-
to sunlight regularly and, when living in
less friendly climates, I will supplement with vegan options.
-
Now, a word of caution- you can take too many vitamin
D supplements, resulting in high blood calcium
-
levels, which can lead to nausea, constipation,
confusion, abnormal heart rhythm, and even
-
kidney stones. So please stay within doctor-recommended
doses.
-
So, to track your own vitamin D, check out
Cronometer. You can enter your meals and activity
-
to make sure you’re right where you want
to be. You can even go and create your own
-
food, select supplement and enter the data
for the supplement you take. Then, in your
-
day’s nutrition report, you can have the option
of showing or hiding your supplements to see
-
where your diet alone measures up. Pretty
freakin’ cool, right? So cool that they’re
-
actually sponsoring this video to get this
information out. And the best part?
-
It's totally free to use these services. Be sure
to use the link in the video description below to make

I myself just found out about the supplement
option on there and kind of had a nerdgasm.
-
Too much?

-
Where do I get my sun from?
-
Vitamin D, not sun...from the sun.
-
These are actually the sunglasses I wear...they go over glasses.
-
Cause I'm to cheap to get a prescription, so.

Rock it out like an old lady who just got her eyes dilated.
