Vitamin D3 Benefits - New Guidelines

Vitamin D3

Vitamin D3 is a fat soluble vitamin that is found in dairy products, some foods, and it is produced from ultraviolet rays from the sun. It is necessary for promoting calcium absorption, in order to have healthy bones and prevent osteoporosis. You used to hear about sailors getting rickets from a lack of vitamin D when on long sea journeys, but there is no reason for anyone to be low on vitamin D today.

Evidence and Amount of D3 Newcessary

There is a growing consensus that people need higher Vitamin D levels than had previously been recommended. The recommended dose for years was individuals under 50 years of age take 200 IU daily, and those 50-70 years of age take 400 IU. Now these dosages are considered too low. Years ago there was much concern about fat soluble vitamins building up in your system and causing negative effects, but at this time scientist can’t even agree on the exact amount an individual needs, and they are not concerned about toxicity, although obviously you wouldn’t take tablets by the handful.

A recent study showed that vitamin D levels in the range of 1000 IU range had excellent outcomes for the elderly and for people with type II diabetes. However, you can not eat enough vitamin D food to get to this level. There are some foods with vitamin d that you will see on the chart below, but the selection is limited, unless you are really fond of cod liver oil.

Vitamin D Deficiency

Treating Vitamin D deficiency treatment is quite simple. You can buy Vitamin D pills over the counter, and you can get them combined with calcium. Doctors also prescribe vitamin D if your level is low, which typically would be a dosage of 50,000 IU once a week. Quite often a short course of the prescription will get you to a healthy level. Researchers, of course, are not going to recommend you live your life in the sun for the sake of vitamin D levels due to the concern of skin cancer. Some sun using sun screen is very healthy but it won’t get your level high enough either.

Osteoporosis (a disease that makes bones thin and brittle, thus causing fractures more easily) is certainly one of the main reasons for increasing your vitamin D level, but it will also help prevent fractures at any age, and help bones grow strong and healthy. If your level of vitamin D is too low you won’t absorb the amount of necessary calcium. Post-menopausal women are at the highest risk for problems.

Other Diseases that Vitamin D Helps Prevent

Another very important reason to be concerned about vitamin d is a low intake is associated with cardiovascular disease, heart failure and possibly type II diabetes. There is a vast amount of ongoing research to determine the healthiest levels. I imagine there will be changing guidelines as they learn more about vitamin D.

Several studies have shown a higher intake correlates with lower incidences of cancers well, particularly colon and colorectal cancers.

Greater sun exposure has also been shown to reduce cancer deaths also.

Autoimmune Disease Require Higher Levels

In my personal situation, I don’t drink milk or eat any dairy products, and yes I do miss cheese and ice cream. I quit drinking milk some years ago. Therefore, there are very few foods to eat that have vitamin D but I do enjoy fish. I take a supplement and the doctor periodically checks my blood level. They recommend that the blood level is higher for people with autoimmune diseases such as lupus, rheumatoid arthritis and multiple sclerosis. Doctors are checking the vitamin D with routine lab work much more frequently now for many people, and if yours is not, then ask.

Many people are taking Vitamin D3 supplements, which are vitamin D tablets along with magnesium and calcium. This is a good way to insure you are getting important protectors available in your bloodstream. Calcium, vitamin D and magnesium have been shown in numerous studies to work well when taken together and the vitamin D is more effective when taken this way.

Summary

I hope this article explains the importance of vitamin D, and the problem with vitamin D deficiency. Also, most people are probably not getting enough vitamin D in their diet, particularly if they are post menopausal or elderly.

Of course, vitamin D is important for growing children as their bones grow so rapidly. At least most children are milk drinkers which is important, but children's vitamins are a good idea. We will be hearing more about this vitamin as new research is completed.

Excellent and interesting article. I started taking Vitamin D at 2,000 IU every day a couple of years ago after my sister sort of introduced me to the idea. For what it's worth, I do think it helps. It especially seems to help during the winter in curtailing the wintertime blues. Not sure why, but that's my take.

Interesting article. As such I have seen that today's lifestyle is not too good for health. We spend time mostly indoor. This might hinder the process of natural vitamin synthesis from Sunlight. But I am not quite sure, if it has any scientific findings.

I do believe that vitamin D is really useful for our body. We need this substance to prevent some serious disease and good for body defense. Good presentation between text, picture, video and table. Thank you very much. Rating up. Take care!

Springboard, If it works why analyze it? You are certainly taking the right amount according to my doctor. Thanks for the comment.

Bandrocker, We do get vitamin D from sunlight, but not enough to meet all our needs. You make a good point about today's lifestyle. Thanks for your comment.

Prasetio, I very much appreciate your comments as always.

I take 2000U a day, and tried the doctor prescribed 50000U per week. Unfortunately, every time I try the larger dose, it seems to coincide with some incidental exposure to posion ivy or mold or some other skin irritant. So now I have stuck in my head 'Big Dose' = 'ugly skin rash', and shy away from the 50000U.

Great article.

I take some Vitamin D but at a much lower dosage. Will rethink the amount I should be taking. Fortunately we generally pick up some sun on our walks and like fish and dairy products. Good article Pamela! Rating it useful as I am sure it will be to many people.

Great information Pam. My mum who is a type 1 diabetic is going through this now with her doctor. After a vast amount of stress she became very tired and lethargic. Her Doctor tested her and told her that she was severely lacking vitamin D. Because she was caring for her sick husband who was house bound and then her sister. She was not getting any sunlight much at all. Thanks for sharing this great information.

Love and Hugs

Jim, I didn't know the higher dose was related to any type of skin rashes. Unless there is a specific reason 2000 IU is a good daily dose. Thanks for your comments.

Peggy, Eating a lot of fish and getting enough sun may be adequate with a small supplement. Thanks for your comments.

Love to Read, It is more common for women than men to be very low anyway. At least the doctor is on top of things. Thanks so much for your comment.

Excellent article on Vitamin D we tend to take things for greated these days - important to have a well rounded diet and be exposed to sun - of course sensible exposure to avoid melanoma and skin damage.

What a great and informative hub, Pamela!

I'm extremely fair and sun-sensitive, so must supplement with Vit. D with my calcium supplement. You've clarified a misconception I've had though. I knew sailors get rickets and that they often lack Vitamin C in their diets, especially the non-officers. I'd always assumed they get plenty of sunshine on ships (one reason I forego cruises is the sun exposure) - so I associated rickets with deprivation of that vitamin. I'd read somewhere that the British sailors were called "limeys" because they tried to carry along a supply of limes to get their Vit. C on long voyages.

But I just read that it is scurvy they get from the lack of Vitamin C and indeed do get rickets from insufficient Vit. D.

I'm pleased to have that misconception sorted out!

Great hub from you, as usual. Thanks for expanding our knowledge. There seems to be some controversy about vit. D deficiency being related to usage of sunscreen. We have a lot to learn about what was once the "norm" in medicine and I appreciate this latest on such an important vitamin.

RTalloni, I agree that we have a lot of learn but I am glad that physicians are finally looking at nutrition as they didn't for many years. I appreciate your comments.

It is good to let people know about vitamin D. But you mixed up something. "You use to hear about sailors getting rickets from lack of vitamin D when on long sea journeys" There is plenty of sunshine on ships, but a lack of fruit. So many sailors got scurvy from lack of vitamin C in fruits. So the English started bringing limes with them and that cured it. They are still called limeys. So vitamin C cured scurvy.

Rickets is a game that English people play. Just kidding! That is cricket. Rickets was an epidemic among American children causing severe bone problems. That was cured with vitamin D. But now rickets is making a comeback since children are avoiding the sun or using sunblock.
