Carlson Labs Vitamin D3

Carlson Labs makes a vitamin D pill that uses the most effective form of supplemental vitamin D available and provides a healthy vitamin D dosage.

Experts contend that vitamin D3 is a superior form for supplementing because your body is familiar with digesting and absorbing this form through the intestines. Vitamin D2 is naturally produced endogenously (in your skin) and immediately used by the body, so taking it orally is not its natural pathway. This is an affordable vitamin D supplement that has no gluten, milk or preservatives.

Frequently Asked Questions About Vitamin D Supplements

What Is Vitamin D?

Vitamin D, often referred to as “the sunshine vitamin,” is well known to be an important nutrient for your health. It is made by the body when sunlight hits the skin, activating its production. This necessary vitamin can also be acquired through certain vitamin D foods, but dietary sources are slim.

The majority of vitamin D foods are fortified with vitamin D, and do not otherwise contain the nutrient. The difficulties in obtaining it contribute to the widespread vitamin D deficiency epidemic that is largely ignored!

Those at the highest risk of deficiency include those who have darker skin, less sun exposure, are older in age and those who use sunscreen. Taking a vitamin D supplement may be necessary for many people.

As an essential nutrient to your health, Vitamin D can be made by the body and consumed through dietary sources. Some vitamin D foods include cold-water fish, eggs, mushrooms and fortified foods like milk. However, these sources do not provide much. Vitamin D supplements are most often in soft gel capsules, tablets, and liquid forms. Some multivitamins are fortified with vitamin D as well.

What Are Vitamin D Supplements?

Vitamin D, an essential nutrient to your health, can be made by the body and consumed through dietary sources. Some vitamin D foods include cold-water fish, eggs, mushrooms and fortified foods like milk. However, these sources do not provide much.

Vitamin D supplements are most often in soft gel capsules, tablets, and liquid forms. Some multivitamins are fortified with vitamin D as well. They can be taken to prevent vitamin D deficiency, and treat symptoms associated with deficiency. There are many benefits to taking vitamin D supplements, which we will go over below.

What Are the Uses & Benefits of Vitamin D

Vitamin D is an essential nutrient that affects a huge number of functions in the body. It’s a very important nutrient to have, and a vitamin D deficiency (which is quite common) can cause a host of problems. There are a ton of vitamin D benefits, the most noteworthy of which include:

  • Deficiency: Vitamin D deficiency is very common, and can cause an increased risk of cardiovascular disease, cancer, cognitive impairment, weak bones, and more. Supplementing with vitamin D can help prevent deficiency, even if you do not live in a sunny climate or have other risk factors for a deficiency. A lot of the vitamin D benefits are really just preventions for the symptoms of vitamin D deficiency.
  • Bones: Vitamin D is required in order for your body to absorb calcium. Thus, getting more vitamin D helps your body to properly absorb calcium, which in turn helps to strengthen bones and reduce the risk of osteoporosis and related issues.
  • Immunity: Vitamin D can help to strengthen the immune system and help reduce the risk of infection. Conversely, a deficiency in vitamin D can increase the risk of autoimmunity and susceptibility to infection.
  • Blood Pressure: Vitamin D plays an important role in the regulation of blood pressure. It is thought that low levels of vitamin D in the body can increase the risk of high blood pressure – although, more research is needed.
  • Diabetes: There is a relationship between vitamin D levels in the body and insulin sensitivity and glucose tolerance. Thus, ensuring sufficient vitamin D intake may help to lower your risk of developing type 2 diabetes.
  • Cancer: Vitamin D plays an important role in regulating cell growth and enabling cell-to-cell communication. One study found that vitamin D can potentially reduce the progression of cancer cells by slowing their growth. Vitamin D deficiency has also been linked to an increased risk of developing certain types of cancer.
  • Pregnancy: Vitamin D deficiency has been linked to an increased risk of preeclampsia, leading many experts to recommend that pregnant mothers take vitamin D regularly. One side effect worth noting is that high levels of vitamin D during pregnancy were linked to a higher-than-average development of food allergies in children for the first 2 years of life.

Harvard University estimates that vitamin D deficiency is a global concern, affecting at least 1 billion people. Vitamin D deficiency can cause symptoms such as bone pain, difficulty thinking clearly, muscle weakness, unexplained fatigue and more.

Overall, there are many reasons to take vitamin D, particularly because so many people are deficient in the key nutrient.

Unless you spend a lot of time outdoors without sunscreen on or eat a very healthy diet with lots of fish, mushrooms, and dairy, it’s likely that you are at least somewhat deficient in vitamin D.

Who Can Benefit from Vitamin D?

  • Those at Risk for Vitamin D Deficiency – Some people have a higher risk of developing vitamin D deficiency due to various factors pertaining to lifestyle, geographic location, skin tone, age, and bodyweight. People who spend less time outdoors, for instance, have a higher risk of vitamin D deficiency due to lack of sun exposure. Using sunscreen and living in a colder climate can have the same effects. Having darker skin increases your risk of deficiency because the pigment in darker skin blocks more UV rays from being absorbed. As you age, you lose vitamin D levels because your body gets less efficient at producing it. Those who are overweight have lower levels of vitamin D as well. If you fit into any or multiple of these categories, you should consider taking a vitamin D product.
  • Those at Risk for Osteoporosis – Vitamin D helps to improve your digestive system’s ability to digest and absorb the mineral calcium, which is extremely important to bone strength and density. This makes vitamin D a good supplement for helping to fight against the development of osteoporosis; a bone condition that occurs when the body does not make enough bone, loses too much bone, or both. Those at risk of osteoporosis include women, smokers, heavy alcohol drinkers, and those older than 30 years old. If people in your family have had osteoporosis, that also raises your risk.
  • Those With High Blood Pressure – High blood pressure is a cardiovascular condition that does not generally cause symptoms, but it increases your risk of cardiovascular diseases and heart attacks. It refers to an elevated amount of pressure that your blood circulation is putting on your artery walls. There are certain factors, including age, race, weight, gender, lifestyle habits and family history that can increase your risk of developing high blood pressure. However, anyone can develop this condition. A Boston University study found that high blood pressure can be improved by increasing vitamin D levels in the body.
  • Athletes – Vitamin D may play an important functional role in muscle tissues. Athletic coaches throughout the 20th century felt that exposing athletes to more sunlight enhanced their performance, which studies have discovered may have been due to enhanced vitamin D levels. Muscles contain a receptor for vitamin D that was discovered in 1985, called a VDR, which has been shown to play a role in muscle growth and function. This means that taking a vitamin D supplement may help to improve muscle growth and function, enhancing athletic performance. At the very least, it can help you avoid a deficiency that helps your body stay in peak condition for training.

Are There Any Side Effects of Vitamin D?

Vitamin D is considered a very safe supplement, and it is well tolerated by most people. However, some people may experience side effects such as sleepiness, weakness, fatigue, headache, loss of appetite, etc. Taking a high vitamin D dosage for a long period of time may cause increased levels of calcium in the bloodstream, or vitamin D toxicity.

How Do I Take Vitamin D?

Vitamin D is a fat-soluble supplement, so it is best taken with a source of fat. It makes no difference if you take it in the morning, midday or afternoon. However, there are some supplements and over the counter medications that may interfere with vitamin D absorption, such as antacids and mineral oils. If you are on prescription medication, talk to your doctor before taking a good vitamin D supplement.

Can I Stack Vitamin D With Other Supplements?

Stacking refers to the idea of combining supplements that have beneficial effects when taken together. There are some supplements that have synergistic benefits when stacked with vitamin D supplements. Here are some supplements go well with vitamin D:

  • Magnesium – Magnesium is an important mineral that can be found in abundance in the human body. Most magnesium in the body is located in your bones. It is important to bone strength and development, and it also plays a role in nerve impulse conduction and muscle contraction. Vitamin D and magnesium are interdependent nutrients. Magnesium plays a role in vitamin D metabolism, and vitamin D plays a role in magnesium levels in the body. Taking these nutrients together prevents magnesium deficiency and improves vitamin D benefits.
  • Calcium – For bone health, taking calcium alongside vitamin D makes a good stack. Taking a calcium supplement can improve vitamin D absorption. If you do not consume enough calcium and you are vitamin D deficient, lack of calcium intake will aggravate the symptoms of vitamin D deficiency. It is also a good vitamin D stack for the elderly. Calcium and vitamin D together can reduce the risk of falls in elderly women by 49% in comparison to taking just calcium alone. This is because these nutrients improve muscle control, strength and bone density.
  • Fish Oil – Fish oil contains healthy omega-3 fatty acids that have cardiovascular health benefits and bone health benefits. Fish oil supplements can help to reduce levels of triglycerides in the bloodstream and lower risk of cardiovascular diseases. Altogether, the benefits of fish oil complement the benefits of vitamin D, and it also provides a source of fat to improve vitamin D absorption.
