Facts About This Vitamin Essential For Your Health

( Don't let your health suffer from Vitamin D Deficiency!)

The most accurate way to know you are vitamin D deficient is with a blood test. The 25-hydroxyvitamin D level should be 50-150 ng/mL for general health, 70-100 ng/mL for optimal bone pain and heart health. To keep your levels in this range, make sure 15 minutes of sun exposure each day or take 1,000 IU of vitamin D3 once per day. You can also make sure you ingest about 600 mg of calcium daily to avoid the risk of falling below the lower level plateau boundary for 25-hydroxyvitamin D.

Vitamin D: A Public Health Crisis


A public health crisis is an event, policy, or situation that threatens the well-being of society. The recent obesity epidemic has led to the emergence of two classifications for this type of crisis: chronic and acute. Chronic public health crises are those for which prevention is complicated by socio-cultural norms and values less responsive to government initiatives. Critical problems occur suddenly due to external events or short-term trends that can be resolved via governmental prevention efforts with various degrees of ease. A public health crisis relating to vitamin D would fall under the category of chronic. It takes years for bone damage caused by low vitamin D levels (which one gets primarily through sun exposure).

Vitamin D deficiency is reaching epidemic proportions with humans and can be considered a public health crisis. Worldwide, 15% of the population has clinical vitamin D deficiency after factors such as age, skin pigmentation, and sun avoidance are considered. In addition, there has been increasing evidence that vitamin D plays an essential role in regulating calcium metabolism, leading to bone disease and other conditions associated with aging. The primary source of our daily requirements is sunlight exposure, even though it weakens moderately over time or increased protection from UV radiation leads to lower levels in the bloodstream. Sources for this secondary active form include dairy products fortified with vitamin d3, fish oil supplements, nitrite-rich foods like cured meats or bacon, and egg yolks.


Vitamin D Deficiency Symptoms

Vitamin D deficiency symptoms are nonspecific and may include fatigue, lowered immunity, depression, hair thinning, weight gain, or loss. Low levels of vitamin D correlate with an increase in cancer risk in all tissues of the body. Studies have found that people who maintained blood levels above 40 ng/mL had a reduced overall cancer rate than people with lower vitamin D levels and the general population when normalized by age cohort.

Including also muscle pains or weakness, which may be caused by increased levels of an enzyme made in muscles. Other investigations have not been able to find a link between vitamin D and muscle strength. It is known that blood calcium levels can affect muscle strength, and vitamin D insufficiency might somehow lower the calcium absorption level in your gut. Still, there has been no evidence to support this finding either.

It is typically suggested that people, including pregnant women and infants up to about 12 months old, consume 1000 IU of vitamin D daily. It also appears that some individuals may need more than 1000 IU of vitamin D a day. Varying the dose by individual needs may help avoid deficiency or keep levels in a more optimal range. As with any supplement, it is best not to take high doses of vitamin D without first discussing it with your healthcare provider since there are risks associated with too much vitamin D intake, such as calcium deposits in the kidneys and muscles; bone thinning, and impaired kidney function (hypercalcemia).

What Does Vitamin D Do for Our Bodies?

Vitamin D is a fat-soluble vitamin that grew out of the need to find a way to provide a nutrient that could remain stable and potent, especially during storage. Vitamin D is activated upon contact with the body's outermost membrane, the epidermis, and was first derived from cod liver oil. It helps control excessive cell growth in different cells, including those found in soft bones and blood vessels. In addition to this critical role, it also assists calcium absorption, making sure you have all your bases covered nutritionally. Severe vitamin d deficiency can lead to osteoporosis or increases susceptibility for chronic pain syndromes such as fibromyalgia or arthritis. 

Vitamin D also helps in calcium metabolism, and bone growth helps prevent colon cancer, breast cancer, and tuberculosis. Improves insulin sensitivity in diabetic patients. Prevents respiratory infections such as pneumonia in children. And maintain a healthy heart, strengthens our immune system, and assists with blood clotting. It has also been shown to help prevent colorectal cancer risk, type 1 diabetes, and bone disorders such as osteoporosis.

Vitamin D benefits all body cells because it performs many different tasks such as regulating calcium levels, supporting optimal muscle function, reducing inflammation, improving immunity, and safeguards against autoimmune diseases like Type I Diabetes. One study has even found that those with high vitamin D levels living within 5km of coastlines were 50% less likely to suffer from major coronary events.

Supports Bone Health

Supports Bone Health because vitamin D is a steroid hormone that interacts with virtually all body cells. It has a role in mineral metabolism and bone formation. There are multiple mechanisms by which vitamin D may support bone health. Vitamin D is necessary for the prevention of rickets, osteomalacia, and osteoporosis because it helps with calcium absorption from food or supplements, increases levels of serum ionized calcium, promote resorption of bone tissue after periods of disuse due to immobilization or illness, enhances synthesis and activity of insulin-like growth factors (IGFs) 1, 2 and 3 which have been implicated in stimulating new bone-cell formation. Additionally, there is a potential blood pressure-lowering effect that occurs through regulation by vitamin D1.

Vitamin D is essential for maintaining healthy bones. Deficiencies in vitamin D are associated with an increased risk factor of osteoporosis and bone fractures, including hip fractures that often result in decreased mobility or death. As more than half of Americans may be an inadequate vitamin or deficient in vitamin D, just about everyone can benefit from including it in their diet. Eating food rich in Vitamin D will allow the body to process the nutrient more efficiently. Therefore, many foods have been fortified with it, and several nutritional supplements daily to achieve their needed dose. 

Supports Muscle Health

Vitamin D supports muscle health because it plays a role in calcium regulation and synthesis, both of which are crucial for muscle integrity. Vitamin D is one of the few well-known vitamins that can improve muscle function to some extent. Research has shown that having enough vitamin D strengthens your ability to stand up, sit down, hold on to things, walk short distances without losing balance or becoming fatigued, and have more muscular endurance. If you have vitamin d deficiency, symptoms could lead to fatigue, slower walking speed, muscle weakness, and smaller muscles. 

The most important source of vitamin d comes from sunlight exposure. Still, vitamin d supplements also provide high-quality vitamin d, but how much you need is debatable, so consult with your doctor.

Supports Immune Health

Vitamin D is necessary to support immune health because the body needs to produce vitamin D for its immune system to function correctly. This includes preventing or combatting colds, the flu, and even skin cancer (or any other disease). Furthermore, dietary calcium (dietary supplements) containing vitamin d supplementation is sold widely across the United States. Still, we should be cautious before trying them out because many of these products are not regulated by FDA regulations.

Supports the Nervous System

Vitamin D supports the nervous system by increasing nerve cells' production and reduces inflammation that may lead to MS. In other words, vitamin d is a fat-soluble vitamin that you might want to consider having additional doses of as it supports your nervous system and possibly can help fight against Multiple Sclerosis.

Causes of Vitamin D Deficiency

Vitamin D deficiency is a condition in which the human body does not receive enough of this vitamin. Low levels may be a consequence of diet, sun exposure, geography, and season. Low levels can also result from certain medical conditions, dark skin pigmentation, time spent indoors, and older age. However, it's scarce to lack vitamin D because of a lack of sunlight exposure or if you're wearing full-body clothing for religious reasons.

People should be aware of the leading causes for Vitamin D Deficiency - other than just not getting enough vitamins (insufficient vitamin) through any means. These include medical conditions such as Coeliac Disease or Crohn's disease, particularly if you're on treatment with steroid medication that causes increased levels of glucose in your body because it interferes with vitamin absorption; lack of sunlight due to the time of year (i.e., winter), location (living inside due to poor weather) or current medical circumstances.


Final Thoughts

Vitamin D is an essential serum vitamin for human health. It's found in a few food sources, but sunlight exposure and supplementation is the best way to get enough of this vital nutrient. If you think that you may be deficient or your children are not getting enough sun time, we have some advice on how to know if you're wrong, as well as what can happen when someone suffers from deficiency.
