Top 16 Best Vitamin D Supplements

Written by Andrew Le, MD

UpdatedOctober 23, 2024

Vitamin D is actually one of the most important nutrients for our health and well-being. While natural food sources are the main source of vitamin D, vitamin D supplements can be recommended when one cannot get enough sunlight or when life restricts one’s time in the sun. So with the best vitamin D supplement, you have everything you want.

Nevertheless, it may be challenging to determine which vitamin D supplement is the best from the many available choices, but don’t worry! From multivitamin supplements for kids that would help them grow strong to vitamin D to help your body function properly, we’ve got you covered. Here’s a guide that will help you when you are searching for the right vitamin D supplement for you. Let's get started!

What is Vitamin D?

Vitamin D is known as the sunshine vitamin, it is a fat soluble vitamin that is a part of a group of compounds referred to as secosteroids. It is present in some foods in its natural state including fatty fish, egg yolk, beef liver, cod liver oil, dairy products that are fortified, and mushrooms.

It can also be synthesized in the body through the skin when one is exposed to the sun. There are different types of vitamin D, mainly vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). The body transforms both forms into an active state prior to using them.

Vitamin D deficiency is one of the most widespread nutrient deficiencies in the world. According to Harvard Medical School, vitamin D is not very abundant in foods as we get older and therefore the deficiency is common.

Most of the time, vitamin D deficiency is linked to increased risks of poor musculoskeletal health such as rickets, falls, osteomalacia, and poor muscle strength.

Vitamin D supplements may be prescribed in instances where a person cannot receive adequate sun exposure or get enough vitamin D from their diet.

What Are the Common Benefits of Vitamin D Supplements?

1. Supports Bones and Teeth Health

Vitamin D commonly enhances and builds teeth and bones. It also assists in maintaining adequate phosphorus and calcium levels which are required for proper mineralization of the teeth and bones.

In other words, calcium, which is good for your teeth and bones, becomes useless without vitamin D. You cannot have strong teeth and healthy bones and they become brittle if you lack vitamin D.

Vitamin D and calcium will prevent osteoporosis, a condition that leads to a reduced rate and quality of bone formation.

2. Enhances Immune Function

Vitamin D plays a crucial role in the functioning of the immune system and prevention of autoimmune diseases. It helps stimulate immune cells and increases their effectiveness, thus enhancing the body’s ability to fight infections. In addition, some research has shown that vitamin D may help decrease the chances of contracting inflammatory diseases.

Lacking vitamin D, people get infections and autoimmune diseases such as type 1 diabetes, rheumatoid arthritis, and inflammatory bowel disease.

3. Muscle Strength and Function

Vitamin D plays an important role in the health of muscles and their ability to remain strong. It assists in avoiding muscle loss and deterioration and contributes to muscle protein formation and utilization.

Deficiency of vitamin D in your body leads to weakness of muscles and can lead to falls which is a major problem that leads to disability and high mortality rates in elderly people. Older people may get some benefits from vitamin D supplements because these products can reduce the chance of bone fractures and falls.

4. Improves Mood and Mental Health

The sun and the rays can lighten up the mood and so can the Vitamin D supplements. Vitamin D receptors are found in areas of the brain that are associated with the regulation of one’s mood. Vitamin D helps to boost the mood and deficiency of vitamin D makes a person more prone to SAD and depression. Therefore, the use of vitamin D supplements could alleviate the symptoms of such diseases.

5. Reduces the Risk of Chronic Diseases

Deficiency of Vitamin D has been associated with increased prevalence of non-communicable diseases such as diabetes, cardiovascular diseases, colon, breast, and prostate infections, and autoimmune diseases. Taking Vitamin D supplements may also be useful in lowering the occurrence or severity of these conditions.

6. Supports Weight Loss

Obese people are more likely to have low vitamin D levels which implies using more vitamin D can assist in weight loss.

Conversely, people who consume a daily vitamin D and calcium supplement may shed more pounds than those taking an inactive supplement. This is because vitamin D and calcium suppress appetite.

However, it is important to note that while vitamin D aids in weight loss, ensure that you undertake a proper weight loss regime that involves proper diet, exercise, and a healthy lifestyle.

Side Effects of Vitamin D Supplements

1. Vitamin D Toxicity

Different guidelines exist for sufficiency of vitamin D, but data suggest that 30-60 ng/mL is probably optimal. Taking extremely high amounts of vitamin D for a long time leads to hypervitaminosis D which is also known as vitamin D toxicity.

Hypervitaminosis D signs and symptoms may include anorexia, vomiting, nausea, fatigue, polyuria, polydipsia, constipation, and confusion. However, hypervitaminosis D is very uncommon and it is characterized by excessive intake of high doses of vitamin D supplements for a long time which is more than 10,000 IU per serving.

For how many vitamin D supplements you should take, we suggest seeking the advice of a healthcare professional.

2. Digestive Issues

Some people get side effects like bloating, stomach aches, poor appetite, diarrhea or constipation after they have taken vitamin D supplements. Most of the time, the side effects of the above medicines are mild and temporary. Another important thing to consider is the fact that not all individuals manifest similar symptoms.

In case the symptoms are not relieved, or they get worse, it is advised to seek medical help.

3. Allergic Reactions

It has been reported that vitamin D supplementation may cause allergic reactions but in rare cases. Possible reactions could be skin rash, itching, hives and even breathing difficulties. We suggest that you consult a doctor as soon as possible if you get any of these signs.

4. Interference with Certain Medical Conditions

It is important to note that vitamin D supplements can sometimes interact with some medicines and health conditions. For example, patients diagnosed with lymphoma, sarcoidosis, hyperparathyroidism, or granulomatous diseases should not take these dietary supplements as they may exacerbate the conditions.

5. Kidney Problems

The use of vitamin D supplements in large amounts may pose the risk of causing harm to the kidneys in the long run. This is because, normally, kidneys are supposed to convert vitamin D into its active form, and taking more vitamin D supplements may lead to straining of the kidneys and formation of kidney stones or possibly kidney failure.

Factors to Consider Before Buying the Best Vitamin D Supplement

1. Ingredients

When choosing the right vitamin D supplements you ought to consider certain ingredients. If you are a vegan or a vegetarian then the individual components of the supplement must be derived from animal-based products. On the other hand if you have a preference for organic or non GMO foods and products then use supplements that bear such labels.

Furthermore, if you have allergies or other sensitive issues, do not take supplements that contain compounds or chemicals that cause the allergies including gluten among others.

2. Types of Vitamin D Supplements

Vitamin D supplements usually come in three main types: liquids, capsules, or chewable.

I). Liquid Supplements

These supplements are in bottles with droppers and the dosage is in drops. These are ideal for individuals who have a problem with swelling capsules like toddlers and older people. In addition, these supplements can be incorporated into foods and beverages.

ii). Capsules

These supplements are mostly liquid based but are encapsulated in a gelatin capsule. They are advised to be taken by people who do not enjoy the plain taste of liquid vitamins.

iii). Chewables

There is also chewable vitamin D if you do not enjoy the idea of liquid or capsule supplements. They are also known as gummy vitamin supplements and are meant to be sweet. These are suitable for children who do not like taking vitamin D drops or those who cannot swallow tablets. They are also suitable for children since they can be taken as candies and hence, it becomes easier to administer them.

3. Forms of Vitamin D

As mentioned earlier, vitamin D has two primary forms: Vitamin D2 and vitamin D3. Vitamin D2 is derived from plants and the common sources include wild mushrooms. On the other hand, vitamin D3 is obtained from sunbathing or from animal products or supplements.

Vitamin D2 is often prescribed by a doctor while vitamin D3 can be purchased without a prescription. This is because vitamin D2 has a potency of more than fifty thousand international units while vitamin D3 has comparatively lower quantities. Moreover, D3 is better absorbed in the body than D2.

4. Vitamin D Dosage

Excess or deficiency of vitamin D in the body is not healthy for you. Follow the NIH's recommended daily allowance (RDA) for your intake and upper limit. Alternatively, you might want to seek advice from your health care provider.

  • Elderlies above 70 years old: 800 IU to 4,000 IU
  • Adults between 19 & 70 years of age: 600 IU to 4,000 IU
  • Teenagers between 14 & 18 years of age: 600 IU to 4,000 IU
  • Kids between 1 & 13 years of age: 600 IU to 2,500 IU
  • Infants between birth and one year old: 400 IU to 1,000 IU
  • Breastfeeding and pregnant women: 600 IU to 4,000 IU

This recommended dietary allowance helps avoid shortfalls rather than adding value to the body. Hence, if a person has a likelihood of having low vitamin D levels, for example, they may need to take larger servings of vitamin D.

Moreover, it is important to note that the RDA is for the total intake between supplements and foods. If you get vitamin D in other ways such as by exposure to sunlight or foods rich in vitamin D, you may require a different dosage of your vitamin supplement.

5. Third-Party Testing

When choosing the proper vitamin D supplement, always check the third-party verification. Choose a vitamin D supplement brand that tests its products for purity, potency, and quality through third parties. Look for certifications by well-known organizations including NSF International or the USP (United States Pharmacopeia).

Information about third-party certifications can be found on the packaging of the supplement or on the manufacturer’s website. If you see certifications pointing to independent testing the product has been tested.

However, even though third-party testing gives reliability to the product, it does not provide assurance for efficacy or even to each consumer. It is therefore advised to seek the advice of a healthcare provider or a registered nutritionist before using any new vitamin D supplement to know whether or not it meets your needs and circumstances.
