Best Vitamin D Supplements in 2024

Vitamin D is a fat-soluble vitamin that improves and supports bone development, teeth, muscles, cardiovascular health, immune function and mental cognition through calcium and phosphorous absorption. While vitamin D can be absorbed naturally through a diet consisting of fatty fish, milk, eggs, and liver, taking a vitamin D supplement will help ensure that the body always has adequate amounts.

There are many health brands that sell vitamin D products as it is cheap to produce and easy to get. Some of these brands outsource production while others produce it in their own facilities. If you are looking for the best vitamin D supplement, choose a company that manufacturers the product itself.

Vitamin D is not only beneficial for improved body functioning, but it is also a cheap supplement that anyone can take. Some popular brands that sell vitamin D include Thorne, Ora Organics, NOW Supplements, Ritual, and BrainMD. While Thorne provides the safest option with it’s NSF certification, all of these trusted brands produce a science-backed product, that is well researched and tested.

What are the Benefits of taking Vitamin D Supplements?

Vitamin D plays a crucial role in the body by promoting calcium absorption in the gut, essential for normal bone mineralization and growth. It also prevents rickets in children and osteomalacia in adults, skeletal diseases that result in weak, brittle bones.

Beyond bone health, Vitamin D is important for muscle function, immune response, and inflammation reduction. Studies suggest that adequate levels of Vitamin D might be protective against certain cancers, heart disease, type 1 diabetes, and multiple sclerosis.

The Institute of Medicine suggests a daily intake of 600 IU (15 mcg) for individuals up to age 70 and 800 IU (20 mcg) for those older to achieve a blood level of 20 ng/ml, considered adequate for bone and overall health in healthy individuals.

What are the Risks of Taking Vitamin D Supplements?

One of the main concerns is Vitamin D toxicity, which can lead to hypercalcemia – a condition characterized by elevated levels of calcium in the blood. Symptoms of hypercalcemia can include nausea, vomiting, weakness, and in severe cases, can result in kidney problems and calcium deposits in the heart and lungs. This condition is most often the result of taking high doses of Vitamin D supplements over an extended period, rather than from dietary sources or sun exposure.

Beyond the risk of toxicity, Vitamin D supplements can interact with various medications, potentially altering their effectiveness. For instance, they can decrease the absorption of certain heart and weight-loss medications and affect the metabolism of drugs used to treat epilepsy. There’s also a potential increased risk of kidney stones, as high doses of Vitamin D can lead to excessive calcium absorption and excretion.

Individuals with specific health conditions, such as hyperparathyroidism or certain lung diseases, may experience complications from increased calcium levels due to high Vitamin D intake. Following recommended dosages and having regular blood tests to monitor Vitamin D levels can help mitigate these risks, ensuring that supplementation contributes positively to overall health without unintended side effects.

Who should take Vitamin D?

Vitamin D is safe for everyone as it is found within many foods naturally. However, it is recommended that young children, as well pregnant or breastfeeding women, take a smaller dose. If you fall within this category, speak with a professional before taking a vitamin D supplement.

What is the recommended intake of Vitamin D?

The recommended intake of Vitamin D is a dosage of 5,000 IU. While the body absorbs vitamin D naturally through some foods, it is safe to take up to 5,000 IU’s.

Can you have too much Vitamin D?

While Vitamin D is essential for health, excessive intake can lead to toxicity, known as hypervitaminosis D. This condition can cause a buildup of calcium in the blood (hypercalcemia), leading to nausea, vomiting, weakness, and serious complications like kidney damage. The safe upper intake level for adults is set at 4,000 IU (100 mcg) per day.

Vitamin D toxicity is usually caused by excessive use of supplements rather than dietary sources or sun exposure. Symptoms of toxicity include persistent nausea, vomiting, muscle weakness, and frequent urination. Treatment involves stopping Vitamin D supplementation and restricting dietary calcium.

Can You Take Vitamin D with Other Supplements

Yes, you can take Vitamin D with other supplements, but it’s important to consider interactions and absorption. Vitamin D pairs well with calcium, magnesium, and Vitamin K for enhanced bone health and overall health benefits. However, always consult a healthcare provider to tailor advice to your specific health needs and to avoid any potential negative interactions.

What are the signs of Vitamin D deficiency?

Vitamin D deficiency can lead to several health issues due to its essential role in calcium absorption and bone metabolism. Early signs of deficiency may be subtle or non-specific, including fatigue, bone pain, muscle weakness, mood changes such as depression, or a general sense of not feeling well. Chronic deficiency can lead to more serious conditions such as rickets in children, and osteomalacia in adults, resulting in bone pain and muscle weakness.

How does Vitamin D Supplementation affect mood?

Research suggests a link between Vitamin D levels and mood regulation, including the risk of depression. Vitamin D receptors are found in many parts of the brain, including areas linked to depression. Some observational studies have found that low Vitamin D levels are associated with an increased risk of depression, though the relationship is not fully understood.

Vitamin D is one of the first supplements given to those that suffer from PTSD as well. However, clinical trials on Vitamin D supplementation for depression have shown mixed results, indicating that while it may benefit some people, especially those with a deficiency, it is not a universal remedy for depression.

Is there a best time of day to take Vitamin D Supplements?

Vitamin D is fat-soluble, meaning it is best absorbed when taken with a meal containing fat. The time of day may not significantly impact absorption as long as it accompanies dietary fat. Some studies suggest taking Vitamin D with the largest meal of the day can significantly increase blood levels, compared to taking it on an empty stomach or with a light meal.

However, consistency is key to maintaining adequate levels, so choosing a time that fits with your daily routine and sticking to it is more important than the specific time of day. This approach ensures that you do not forget to take your supplement.

How long does it take for Vitamin D levels to improve with supplementation?

The time it takes for Vitamin D levels to improve with supplementation can vary depending on the baseline level of deficiency, the dosage of Vitamin D supplement, and individual factors such as body weight, gut health, and how consistently the supplement is taken. Generally, it takes about 2-3 months of regular supplementation to significantly increase Vitamin D levels.

For those with severe deficiency or conditions affecting absorption, it may take longer to reach optimal levels. Monitoring Vitamin D levels through blood tests is crucial to adjusting the supplement dose as needed to avoid deficiency or toxicity. It’s important to work with a healthcare provider to determine the most appropriate regimen for your specific needs.

How much it will cost for Vitamin D supplements?

A vitamin D supplement is a low priced supplement that ranges in price based on ingredients and certifications. Generally, a top of the line vitamin D supplement will cost $0.25 per 5,000 IU, such as Thorne.

What are the brands that sell Vitamin D Supplements?

There are many brands that sell vitamin D, these include; Thorne, Ora Organics, NOW Supplements, Ritual, Brain MD, Garden of Life, Pure Encapsulation, NatureWise, Nature Made, and Sports Research.
