Top 15 Best Vitamin D Supplements

Vitamin D is quite an essential nutrient for our health and well-being. Though sunlight exposure is the primary source of vitamin D, vitamin D supplements are often recommended to ensure optimal levels, especially when sunlight is limited or when life keeps us indoors. With the best vitamin D supplement, you have all you need.

However, choosing the best vitamin D supplements from the many options can be overwhelming, but worry less! Whether you want a dietary supplement to keep your kids strong and healthy or boost your vitamin D levels, we've got your back. Here's everything you need to know when looking for the best vitamin D supplement that meets your needs. Let's get started!

What is Vitamin D?

Vitamin D, "the sunshine vitamin," is usually a fat-soluble vitamin belonging to a group of compounds referred to as secosteroids. It's naturally found in some foods, such as fatty fish, egg yolks, beef liver, cod liver oil, fortified dairy products, and mushrooms.

Our body also produces it through the skin when exposed to sunlight. Vitamin D usually comes in different forms, mainly in vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). The body converts both forms into an active state before using them.

Low vitamin D is among the most common essential nutrient deficiencies globally. A study by Harvard Medical School states that vitamin D deficiency is quite common as we age because there aren't many naturally rich foods.

Vitamin D deficiency is usually associated with a higher risk of poor musculoskeletal health, like rickets, falls, osteomalacia, and poor muscle strength.

In cases where sunlight exposure or dietary intake is inadequate, vitamin D supplements may be recommended to maintain optimal vitamin D levels.

What Are the Common Benefits of Vitamin D Supplements?

1. Supports Bones and Teeth Health

Vitamin D usually strengthens and develops teeth and bones. It also helps maintain optimal levels of phosphorus and calcium, which are necessary for healthy tooth and bone mineralization.

Essentially, calcium, which benefits your teeth and bones, would be unable to function without vitamin D. You need vitamin D for strong teeth and bone growth—and to prevent teeth and bones from becoming brittle.

Vitamin D and calcium will prevent osteoporosis, a condition that causes a decrease in bone mineral density and quality.

2. Enhances Immune Function

Vitamin D is vital for supporting the immune system and reducing the risk of autoimmune diseases. It helps activate immune cells and boosts their function, making the body more resistant to infections. Besides, some studies suggest that vitamin D supplementation can reduce the risk of developing inflammatory diseases.

Individuals with inadequate vitamin D levels tend to get infections and autoimmune diseases like type 1 diabetes, rheumatoid arthritis, and inflammatory bowel disease.

3. Muscle Strength and Function

Vitamin D is vital for maintaining muscular strength and health. It helps prevent muscle wasting and atrophy and supports the production and functioning of muscle proteins.

Vitamin D deficiency in your body can cause weak muscles, which increases the risk of falls—a major issue that causes significant impairment and mortality, especially in older adults. Vitamin D supplements may benefit older adults, as they can help lower the risk of fractures and falls.

4. Improves Mood and Mental Health

Sun exposure can brighten up your mood, and so can vitamin D supplements. Vitamin D receptors are present in brain areas involved in mood regulation. Adequate vitamin D levels are associated with improved mood, and deficiencies of this essential nutrient have been linked to higher chances of seasonal affective disorder (SAD) and depression. Therefore, supplementing with vitamin D may help reduce the symptoms of these conditions.

5. Reduces the Risk of Chronic Diseases

Vitamin D inadequacy has been linked to a higher chance of chronic diseases such as diabetes, cardiovascular disease, some types of cancer (colon, breast, and prostate infections), and autoimmune disorders. Vitamin D supplements may help reduce the severity or risk of these conditions.

6. Supports Weight Loss

Individuals with obesity have a greater chance of low vitamin D levels, meaning more vitamin D may help with weight loss.

On the other hand, individuals taking daily vitamin D and calcium supplements may lose more weight than those taking a placebo supplement. This is because vitamin D and calcium have an appetite-suppressing effect.

However, note that although vitamin D supports weight loss, you should incorporate a nutritious diet, regular exercise, and healthy lifestyle habits into your daily routine as part of a comprehensive weight management plan.

Side Effects of Vitamin D Supplements

1. Vitamin D Toxicity

Although recommendations for adequate vitamin D levels vary, research indicates that 30–60 ng/mL levels are likely ideal. Consuming extremely high levels of vitamin D for a long period can result in vitamin D toxicity, also referred to as hypervitaminosis D.

Symptoms of hypervitaminosis D may include loss of appetite, vomiting, nausea, weakness, frequent urination, excessive thirst, constipation, and confusion. However, hypervitaminosis D is rare and occurs when a person takes extremely high dosages of vitamin D supplements, exceeding 10,000 IU per serving for a lengthy period.

We recommend consulting a healthcare expert on how many vitamin D supplements you should take.

2. Digestive Issues

Some individuals may experience digestive issues such as bloating, stomach pain, poor appetite, diarrhea, or constipation after taking vitamin D supplements. These side effects are mild and temporary, most of the time. Also, note that not all people experience the same symptoms.

If the symptoms persist or worsen, we recommend consulting a healthcare professional.

3. Allergic Reactions

Vitamin D supplementation has been linked to allergic reactions, although in extremely rare cases. Symptoms of an allergic reaction could include rashes, itching, hives, or difficulty breathing. We recommend seeking medical help immediately if you experience any of these symptoms.

4. Interference with Certain Medical Conditions

Vitamin D supplements may interfere with certain medications or health conditions. For instance, individuals with lymphoma, sarcoidosis, hyperparathyroidism, or granulomatous disorders should be cautious when taking these dietary supplements, as they can worsen these conditions.

5. Kidney Problems

Excessive intake of vitamin D supplements might potentially damage the kidneys over time. Since the kidneys are usually responsible for converting vitamin D into its active form, excessive vitamin D supplements might overwork them, resulting in kidney stones or, in the worst case, kidney failure.

Factors to Consider Before Buying the Best Vitamin D Supplement

1. Ingredients

Before buying the best vitamin D supplements, pay attention to the ingredients. If you are a vegan or vegetarian, you'll want to ensure that the components of the supplements are made from animal-based foods. On the other hand, if you prefer organic or non-GMO products, go for supplements with these certifications on their labels.

Moreover, if you have allergies or other sensitive issues, avoid supplements that contain ingredients that might cause the allergies, such as gluten, among other compounds and chemicals.

2. Types of Vitamin D Supplements

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

I). Liquid Supplements

These supplements come in bottles with droppers and are administered in drops. It is recommended for those with difficulty swelling capsules, such as toddlers and older adults. Besides, these supplements can be added to food and drinks.

ii). Capsules

These supplements are usually in liquid form but contained inside a gelatin capsule. They are recommended for people who don't like the direct taste of liquid vitamin supplements.

iii). Chewables

Another option is chewable vitamin D if you don't like liquid or capsule supplements. They are also called gummy vitamin supplements and are designed to be sweet. They are ideal for those who dislike vitamin D drops or swallowing tablets. They are also perfect for kids since they can take them as treats, making it 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 plant-based and comes from plants such as wild mushrooms. Conversely, vitamin D3 comes from sunlight exposure, animal sources, or dietary supplements.

Most vitamin D2 is sold as a prescription, while vitamin D3 is sold over the counter. This is because vitamin D2 has a potency of over 50,000 IU, while vitamin D3 has lower amounts. Also, D3 is more readily absorbed in the body.

4. Vitamin D Dosage

Too little or too much vitamin D will harm you. Follow the NIH's recommended daily allowance (RDA) for your intake and upper limit. Alternatively, you can consult your healthcare professional for guidance.

• 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 prevents shortfalls instead of enhancing overall health. Therefore, if an individual is at a greater risk of vitamin D inadequacy, for instance, a larger vitamin D dosage may be required.

Furthermore, keep in mind that the RDA represents the total intake from supplements and dietary sources. You may need to adjust your vitamin supplement dosage if you get vitamin D from other sources, like sunlight exposure or fortified foods.

5. Third-Party Testing

When shopping for the best vitamin D supplement, ensure it's third-party tested. Go for a vitamin D supplement brand that conducts third-party testing to ensure its products' purity, potency, and quality. Check out certifications from reputable organizations such as NSF International or the USP (United States Pharmacopeia).

Look for information on the product label or the manufacturer's website to see if a vitamin D supplement has passed third-party testing. If you find certifications mentioning independent testing, the product has been tested.

However, though third-party testing adds credibility to a product, it does not guarantee effectiveness or individual results. It's therefore recommended to consult a healthcare practitioner or a certified nutritionist before starting any new vitamin D supplement to determine its suitability for your specific requirements and circumstances.
