Warnings Of Vitamin D And D3

Vitamin D 50,000

Vitamin D toxicity may occur with excessively high doses. Symptoms could include nausea, vomiting, loss of appetite, constipation, dehydration, fatigue, and confusion. Due to the fact that vitamin D is a fat-soluble drug, the effects of vitamin D therapy can last 2 months or more after therapy is discontinued. It is also important to know the vitamin D content of other supplements you may be taking, such as a daily multivitamin. You should not take high doses of vitamin D supplements without your doctors instruction.

What Should I Watch For While Using This Medication

Visit your care team for regular checks on your progress. You may need blood work done while you are taking this medication. Tell your care team if your symptoms do not start to get better or if they get worse.

Do not take any non-prescription medications that have vitamin D, phosphorus, magnesium, or calcium including antacids while taking this medication, unless your care team says you can. The extra supplements can cause side effects.

What Are The Main Differences Between Vitamin D And D3

The term vitamin D is kind of a misnomer because you will not find anything labeled simply as vitamin D in a pharmacy vitamin aisle. Rather, your choices will be vitamin D2 or vitamin D3 . Generally, when one mentions vitamin D, the implied selection is vitamin D2. For the purpose of this article, when vitamin D is mentioned, it will refer to vitamin D2. The names can be confusing, because many times, patients go into the pharmacy looking for vitamin D and are surprised that there is a D2 and a D3.

Vitamin D comes from plant sources, such as wild mushrooms, as well as fortified foods, such as milk or cereal products. Its strength is typically measured in international units, which is abbreviated as IU on labeling. The 50,000 IU capsules are prescription only, while lower strengths are available over-the-counter. Vitamin D is less expensive to produce and therefore is the form most commonly found in fortified food products.

Vitamin D3 mainly comes from animal sources such as fish oil, fatty fish, liver, and egg yolks. When your skin is exposed to sunlight, it produces vitamin D3. For this reason, it is sometimes referred to as the sunshine vitamin. Its strength is also measured in international units. All forms of vitamin D3 are available over-the-counter.

Weekly And Biweekly Vitamin D2 Prevents Vitamin D Deficiency

Boston University Medical Center
Researchers have found that 50,000 International Units of vitamin D2, given weekly for eight weeks, effectively treats vitamin D deficiency.

Boston University School of Medicine researchers have found that 50,000 International Units of vitamin D2, given weekly for eight weeks, effectively treats vitamin D deficiency. Vitamin D2 is a mainstay for the prevention and treatment of vitamin D deficiency in children and adults. Continued treatment with the same dose of vitamin D2 every other week for up to six years after the initial eight-week period prevents vitamin D deficiency from recurring with no toxicity.

The BUSM study appears online in the journal Archives of Internal Medicine.

Vitamin D is essential for strong bones because it helps the body absorb calcium and phosphorus from the food we eat. Vitamin D deficiency can lead to rickets in children and the painful bone disease osteomalacia in adults. Vitamin D deficiency can also cause osteoporosis and has been linked to increased risk of cancer, heart disease, diabetes, autoimmune diseases and infectious diseases including influenza, according to senior author Michael F. Holick, PhD, MD, director of the Bone Healthcare Clinic and the Vitamin D, Skin and Bone Research Laboratory at Boston University School of Medicine.

Quest Diagnostics, the nation’s leading provider of diagnostics testing, information and services, analyzed the specimens used in the study.

Surrogate Versus Clinical Outcomes

Best Vitamin D2 1.25 Mg 50000 Unit

Although 25-hydroxyvitamin D levels are a better surrogate than a rat binding study, clinical outcomes are the most relevant. Low levels of 25-hydroxyvitamin D are very common in North America and have been associated with a wide variety of diseases including osteoporosis, bone fractures, malignancy, cardiovascular disease, infections, and more. The majority of the data supports association, not causation, of low vitamin D levels. In other words, much of the data does not clearly support the idea that vitamin D supplementation in a patient with low vitamin D levels reduces the risk of these diseases.

With that said, a recent Cochrane review analyzed the all-cause mortality benefit of vitamin D supplementation by pooling 95,286 participants from 56 randomized clinical trials. In this meta-analysis, about 80% of participants received cholecalciferol and about 20% received ergocalciferol . The vast majority were women , and most were older than 70 years of age.

Scientists have shown this may be due to vitamin Ds effect at the cellular level where it augments mitochondrial oxidative phosphorylation in skeletal muscle. This decreases muscle fatigue.
