The Many Benefits Of Vitamin D3

Health & Nutrition : Health Benefits of Vitamin D3

Vitamin D3 can have an impact on as many as 2,000 different genes within the body, and has a direct role on far more aspects of health than many might realize.

Vitamin D receptors are found in nearly every cell, and as soon as D binds to a receptor, it turns genes on or off, prompting changes at the cellular level. Studies completed over the last two decades have proven that this process turns off cancer-causing genes, turns on immunoprotective genes, and even tells cells which vitamins and minerals to absorb. This all has a great effect on many important body processes, including:

Bone health

Strong bones are a result of good vitamin D3 intake because it helps regulate and control the bodys ability to absorb phosphorus and calciumtwo compounds that provide density and strength to the skeletal system and teeth.

Insulin control

Vitamin D3 stimulates the pancreas and triggers the process to make insulin. This is key for managing blood sugar levels more effectively and can help diabetics better control the disease.

Lower blood pressure

A study from Boston University found that those with high blood pressure experienced a drop in numbers when vitamin D levels were increased. D3 actively reduces the concentration of renin, an enzyme secreted by the kidney that has an affect on blood vessels.

Possible cancer prevention

How Is Vitamin D Deficiency Treated

The goals of treatment and prevention are the sameto reach, and then maintain, an adequate level of vitamin D in the body. While you might consider eating more foods that contain vitamin D and getting a little bit of sunlight, you will likely be told to take vitamin D supplements.

Vitamin D comes in two forms: D2 and D3. D2, also called ergocalciferol, comes from plants. D3, also called cholecalciferol, comes from animals. You need a prescription to get D2. D3, however, is available over the counter. It is more easily absorbed than D2 and lasts longer in the body dose-for-dose. Work with your doctor to find out if you need to take a vitamin supplement and how much to take if it is needed.

Should Everyone Get Their Vitamin D Levels Checked Generally No

Karl Insogna, MD, director of Yale Medicines Bone Center

Most people should be fine. Testing is important only for certain populations: for people who are institutionalized for patients with a gastrointestinal disorder or osteoporosis those who have had weight loss surgery those on anti-convulsant medications and children who are immobilized and not outside and active. If youre over 70, I recommend getting your levels checked at least one time.

People whose cultural or religious beliefs require them to be fully clothed, especially if theyre living in northern climates, and whose dietary habits include little or no dairy , may also be vitamin D-deficient and should be tested.

Vitamin D is often referred to as a steroid hormone because it has a potent effect on other hormones. In the research youll often find it labelled as a secosteroid, purely due to its action on the endocrine system.

It acts kind of like a chaperone, guiding nutrients into manufacturing other important hormones.

There are two forms of the nutrient:

  • Ergocalciferol D2

Vitamin D3 its much more bioavailable than ergocalciferol in fact, taking a D2 dose can actually reduce D3 levels .

Considered safe < 100 ng/mL

The largest meta-analysis ever conducted on all of the published studies between 1966 and 2013 regarding 25D levels and all-cause mortality found that the lowest mortality risk is seen when the levels are > 40 ng/mL. According to this, the IOM guidelines are too low and there is a plea calling on the public health authorities to change the recommendations for both the ideal blood level and the requirements needed to achieve this level.

Your 25D level will change by season if you vary how much time you spend in the sun each season. Keep this in mind when scheduling your test.

Drug Interactions Of Vitamin D2 Vs D3

Vitamin D2 and D3 each are metabolized by the liver to 25D, and therefore the potential drug interactions are similar for both forms. Vitamin D may increase the serum levels of aluminum when taken with aluminum hydroxide, a common antacid, and therefore the combination should be avoided. Thiazide diuretics, such as hydrochlorothiazide, may increase the chance of vitamin D raising calcium levels in the blood to a dangerously high level. Patients on both thiazide diuretics and vitamin D supplementation should be monitored for this effect by their healthcare provider. Some drugs may decrease the absorption and effectiveness of your vitamin D supplement. Bile-acid sequestrants, such as cholestyramine, are an example of a drug which will impair vitamin D absorption. Vitamin D and cholestyramine should not be administered at the same time.

The following table may not be a complete list of drug interactions. Please consult your pharmacist or healthcare provider for more information and a complete list of interactions.

Vitamin D Level: Confusion Reigns

There is no universal agreement on what constitutes an ideal vitamin D level, and studies are contradictory. In 2007, Michael F. Holick, M.D., Ph.D. published an article in The New England Journal of Medicine stating that vitamin D levels ranging between 21 to 29 ng/mL were linked to an increased risk of various diseases, including cancer, diabetes, and depression, among others. Thus, he opined that the normal values at that time should be lowered to below 21.

Then, in 2010, the United States and Canadian governments asked the Institute of Medicine to assess data on health outcomes associated with calcium and vitamin D. Their was a vitamin D level of 20 ng/ML or higher was normal and a vitamin D deficiency occurred only in levels below 20 ng/ML.

To make things even more confusing, in 2011 The Journal of Clinical Endocrinology & Metabolism published a study that suggested vitamin D levels of 30 ng/mL were considered normalbut to guarantee an optimal level, 40 to 60 ng/mL was recommended in adults and children.

So, whats the right vitamin D level? Below 20 ng/ML? Above 20? Above 30? Above 40?

Choosing Vitamin D Supplements

Because it’s inadvisable to expose skin to excess UV rays and it can be challenging to get enough vitamin D from food, one way to boost vitamin D intake is with supplements.

There are two forms of vitamin D supplements: ergocalciferol and cholecalciferol . While some experts prefer D3 supplements, there is no strong evidence to believe that one is better than the other when consumed in nutritional doses. At high doses, D2 may be less potent.

Vitamin D supplements come in capsule, gummy, liquid, or chewable tablet forms. Vitamin D is also often found in multivitamins and calcium supplements. Whichever you take, it’s important to read labels so that you know how much you’re getting.

Most vitamin D supplements provide 400 IU per dose, which is several hundred IU shy of the RDA. But most individuals get some vitamin D naturally from sun exposure and by consuming fortified foods.

It is also important to make sure you’re not getting too much vitamin D. The upper limit for children over age 9 and adults is 4,000 IU per day. Too much vitamin D can be harmful. Signs of toxicity include nausea, vomiting, poor appetite, constipation, weakness, and weight loss.

Excess vitamin D also can cause damage to kidneys and increase the levels of calcium in the blooda condition called hypercalcemia that can cause confusion, disorientation, and problems with heart rhythm.
