Is it true that Vitamins A & D mediate each other, that when you take both of them you are able to ingest more than you would normally without having toxic effects?

fish oil?

Not him. It's you~

YOU ARE A USELESS YANKEE DICKHEAD

HAHA geese?!!?

i know, but what I needed, you can only get through prescription. I'm from the US by the way,lol..it was only for a short time anyway.

I love you.

A interesting poeitic and close look to our paradox (with reference to the video response) of sun dependecy of vitamin D and to where (western) society has evolved to. Hypothesis: If humans can maintain there vitamin D status well by exposure to the sun, then the amount of consumed vitamin D supplementation should signal society's health.

Your medical knowledge aside, You are brilliant at conveying the info to the public. You should consider that as a gift.... THANK YOU!!!

Check your mailbox, man!

Too much traffic noise to really enjoy the video and bad sound quality on top of it. Milk in no way contains enough Vitamin D to sustain healthy levels, just forget about milk. Besides, many people are lactose intolerant. Fish may be contaminated with mercury or other toxins like antibiotics if it's from fish farms, not really serious to recommend this either. Besides, the fish dies in the process and the oceans are "overfished" already. Just get supplements or go in the sun. Shirt off, leg free

nice!

You know what i mean about sun and skin cancer.. Also its only curable when its caught early, there is an advert going around on tv right now saying that a guy has gotten it and he didnt see a doctor intime, it is now incurable.

Haxmuch: The sun doesn't CAUSE cancer. Frying yourself in the sun for too long is what MAY cause cancer. And skin cancer is the most curable, treatable form of cancer... Excellent video -- especially re the dangers of sunscreens and suntan lotion.

This was a great vid.I take 1000 IU of vitamin D,probiotics,and other supplements as well.I have ADD and anxiety and my symptoms have greatly improved with the combination of supplements I'm taking.

Ironcily enough, vitamin D stops cancer, but to get vitamin D, you need to get in the sun. The sun causes cancer, such as skin cancer. :)

Great topic! Most people I know definitely aren't getting enough sun. =(

There is only one type of cholesterol. Cholesterol itself. It is is one substance NOT 2. HDL and LDL are NOT cholesterol AT ALL. They are liproteins and noether is good or bad. They are both very important. The Cholesterol Theory of CHD has repeatedly been shown to be false. Look into Dr. Uffe Ravnskov and ANTHONY COLPO The Cholesterol Theory is a SCAM

Is there a way to get too much Vitamin D? Let's say I take a multi-vitamin with 600IU and then eats foods such as OJ with Vitamin D. If I'm also in the sun then would I get an "overdose"?

1000 IU vitamin D3 supplements, 200 capsules sell for about 6.99$. 400IU vitamin D3 supplements, 80 capsules sell for about 2.99$. You don't have to buy them at some complicated place, if you live in canada you can easily walk into a Loblaws store, go in the supplement section near the organic stuff and pick up a 6.99$ D3 supplement. Read the label for D3 as it is better than D2 (from 3 to 10 times stronger).

This one was for parduspilot!!!

There are diferent types of cholesterol: you have LDL cholesterol which is the bad one that can block your artheries, and there is HDL cholesterol which is the good one, and actually cleans your artheries.This one is gained by consuming healthy fats, such as omega 3 and 6 found in crude extra virgin olive oil, fatty fish such as salmon and tuna, nuts,avocado,etc. So I believe that the precursor is HDL cholesterol, rather than LDL cholesterol, which is what people want to reduce.

I looked into Vitamin D3's precursor. Guess what? Its precursor is CHOLESTEROL. Makes me wonder if so many people should be concerned about reducing their cholesterol. Would it be true the less cholesterol one has the less is available to become Vitamin D3?

What is the precursor compound that sunlight turns into vitamin D? Are lots of people deficient in the precursor?

In the USA vitamin D is available as a non-prescription health supplement, and its quite cheap.
