What Is The Use Of Vitamin D3

What Are The Main Differences Between Vitamin D And D3

Is it Safe to Take 10,000 IUs of Vitamin 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.

And when we do venture out into sunny weather, many of us use SPF creams and cosmetics to protect our skin. However, the ingredients in these products block the UV rays that the skin needs to be able to produce vitamin D.

  • people who dont get much exposure to the sun
  • older adults

Does Vitamin D3 Give You Energy

Increasing vitamin D intake is thought to improve energy. A clinical trial was done examining fatigue levels in patients who were identified as vitamin D deficient. These patients were given vitamin D3 supplementation to increase blood levels of vitamin D, and the results showed a significant improvement in fatigue levels. 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.

Are Vitamin D Or D3 The Same

When we refer to vitamin D, we are talking about Vitamin D2. Vitamin D2 and D3 are both widely used vitamin D supplements but are not the same. Vitamin D2 is ergocalciferol and comes from plant-based sources. Vitamin D3 is cholecalciferol and comes from animal-based sources. Both supplements are processed in the body by the liver to 25-hydroxyvitamin D, though vitamin D3 is thought to provide higher levels of 25D. Some formulations of vitamin D2 are prescription only, while all formulations of vitamin D3 are over-the-counter.

What Is Vitamin D

The D vitamins are fat-soluble vitamins that play an important role in calcium absorption and bone health, as well as immune function. Our skin produces vitamin D when exposed to sunlight, but due to the skin cancer risk, many people avoid sun exposure or use sunscreen, which prevents the body from producing vitamin D. Many types of milk and dairy products, along with orange juice, are also fortified with vitamin D. Still, many of us do not get enough vitamin D and need to take a supplement. There are two forms of vitamin D dietary supplements: vitamin D2 and vitamin D3 , and it is important to understand their differences when choosing which vitamin D supplement to take.

Drug Interactions Of Vitamin D2 Vs D3

Nature

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.

What Is The Optimal Intake For Vitamin D

There is still debate about which vitamin D blood levels produce benefits. The very latest evidence suggests that circulating levels in excess of 50 nmol/L, or even 75 nmol/L, may be optimal for overall health. Those below 30 nmol/L, on the other hand, are associated with adverse effects on health.

Achieving a blood concentration of 75 nmol/L often requires supplementation with at least 2000IU a day. In the same vein, taking 3000IU a day for eight weeks has been shown to result in a concentration of more than 75 nmol/L of 25D .

In 2010, more than 40 international scientists called for greater awareness among doctors of the importance of vitamin D in preventing osteoporosis and cardiovascular disease. They recommended that the entire Western population should supplement with 1000-2000IU, especially from October to March.

Vitamin D3 Helps Build A Strong Body

D3 benefits your body physiologically. It helps build strong muscles, and along with calcium it builds strong bones, too. Vitamin D3 benefits your body throughout your life, but as you age it can become harder for your skin to absorb it in the sun. Additionally, if you wear sunscreen or T-shirts to protect your skin from the sun, D3 does not develop in your body. If there is not enough D3 in your body, you can have severe problems like ongoing deficiency or bone issues.

Vitamin D May Fight Disease

In addition to its primary benefits, research suggests that vitamin D may also play a role in:

  • Reducing the risk of multiple sclerosis . A 2018 review of population-based studies found that low levels of vitamin D are linked with an increased risk of MS (

9 ).

In one study, people with obesity who received vitamin D supplements in addition to following a weight loss diet plan lost more weight and fat mass than the members of the placebo group, who only followed the diet plan .

In an older study, people taking daily calcium and vitamin D supplements lost more weight than subjects taking a placebo supplement. The researchers suggest that the extra calcium and vitamin D may have had an appetite-suppressing effect .

The current research doesnt support the idea that vitamin D would cause weight loss, but there appears to be a relationship between vitamin D and weight.

What Are Signs Of A D3 Deficiency

Vitamin D may be the sunshine vitamin, but you can also get it from your diet.

Either way, most Americans are not getting enough of vitamin D. , more than 90 percent of American men dont get enough vitamin D in their diets. But that doesnt necessarily mean theyre deficient, says Yawitz. Your body makes vitamin D3 when your skin is exposed to sunshine. So even if you dont eat a lot of foods that are naturally high in D3, your D levels could be fine if you regularly spend even a few minutes in direct sunlight.

And a true vitamin D3 deficiency can be difficult to identify, simply because there arent a lot of easy-to-spot symptoms. Severe deficiency can lead to osteomalaciaa condition that causes weak and painful bones and sometimes dental issues, she says.

One large study also found that people with low vitamin D levels are more likely to experience depression. However, depression alone isnt a good indicator of low vitamin D3 status.

How Is Vitamin D Deficiency Diagnosed

Healthcare providers dont usually order routine checks of vitamin D levels, but they might need to check your levels if you have certain medical conditions or risk factors for vitamin D deficiency and/or have symptoms of it.

Your provider can order a blood test to measure your levels of vitamin D. There are two types of tests that they might order, but the most common is the 25-hydroxyvitamin D, known as 25D for short.
