What is the cost Eric?
May I ask?


You can get over a hundred 5,000 IU pills of D-3 at iHerb for less than $10.  Use the code ZEB079 when you check out to save $5 and support the site.

Their supplements are the best quality and price with high turnover, ensuring freshness.

Hi Eric,
Just to say that I got 6 months supply of good quality vitamin D3 5000iu gel capsules, from Iherb. No other crap in them :) They came all the way from CA to England for 8 dollars shipping. so £19 has got me 6 months supply. VERY reasonable.
I shall start dosing with 10,000 per day straight away :)
thank you!

It is really not, according to my understanding, necessary to artificially supplement with high doses of any nutrient, vitamin or mineral if you eat properly.  Organ meats, fish, fish oils, etc are good sources of calciferol.  Calciferol, or Vitamin D, is not a true vitamin in that an ongoing ingestion of it is not necessary to sustain normal levels in the body.

Also, the sun is not a source of vitamin D.  Sunlight catalyzes production of vitamin D from a specific type of cholesterol in the skin.

Someone already touched on this in an earlier post, but I think it bears repeating.  It is possible to get too much of a good thing.  If you've had a good complete blood work up lately and everything is in balance, just keep doing what you're doing.

no wisdom,just a comment. my GF (62 y.o) and my youngest (17 y.o) both have documented deficiencies. my doctor is great and very ok with my self management,to a point. she digs in at some testing-homocystine and c-reactive. will push her for D levels on next lab. i am old school,where > 400u/day would make your liver explode and you would die. new tech/labs show much deficiency in the general population. i am thinking about going to 1000u D-3/day and await future labs. comments/input? thanks.

One sardine a day. You could live in a cave it has so much D! Eat the bone for calcium. I suspect pills are no good. And RDA probably exeeds actual need on cavemane diet, as grains and dairy deplete calcium.

No Vit D supplementation is required if you get out into the sun for 15mins a day.
Its definitely recommended to take up to 400UI a day together with calcium for the older population to prevent osteoporosis.

I don't know where she got it, but grains and dairy products do deplete calcium.  They cause the blood to become more acidic, and the body leaches calcium from its own bones to buffer the blood pH.

i can understand dairy product making blood more acid, as high protein intake tends to do that.

but Ca+ to buffer? no sure about that

since years we were told to drink milk and cottage cheese to get more calcium so it's hard to believe adding calcium to your body depletes it...

Dairy Foods     Serving     calcium (mg)
Milk, with added calcium    
1 cup 430

Milk, whole, 2%, 1% skim    
1 cup 300

Milk, evaporated    
1/2 cup  367

Cheese, hard    
50 gm  360 (average)*

etc

One of the things you'll find out here is that the accepted "common wisdom" in nutrition "science" is often highly questionable.

Milk does contain a lot of calcium, but it seems that calcium balance for pH maintenance is a more important issue in adults than is calcium intake.  Probably the only thing in milk that helps bones in adults is the artificially added vitamin D.  For example:

Quote
An adequate vitamin D intake is associated with a lower risk of osteoporotic hip fractures in postmenopausal women. Neither milk nor a high-calcium diet appears to reduce risk.

http://www.ajcn.org/cgi/content/abstract/77/2/504

Apparently the actual milk is bad enough to offset the added vitamin D.

I take 5,000 IU every second day and I get it very cheaply here:
http://www.iherb.com/Now-Foods-Vitamin-D-3-Highest-Potency-5-000-IU-120-Softgels/10421?at=0

Be sure and get D3 though. AFAIK it's hard to over do the D unless you're taking around 10,000IU daily for over three months.

The vitamin D council has a good newsletter you can subscribe to:
