What Are the Signs You Need Vitamin D?
Many vitamin D patients are asymptomatic and only discover they are deficient during routine physical exams.
Often, there are no clear signs that you need more vitamin D, as many people with a deficiency do not experience obvious symptoms. However, some common symptoms that may indicate a deficiency include persistent fatigue, depression, and mood changes, as well as frequent infections due to a weakened immune system. Other signs can include bone and muscle pain, hair loss, and unexpected weight gain. If you are experiencing any of these symptoms, consult a healthcare provider to check your vitamin D levels.
Vitamin D plays a crucial role in several bodily functions. It works with calcium to protect you from developing osteoporosis, a condition that weakens bones and makes them more prone to fractures. Beyond bone health, vitamin D is vital for muscle movement, as muscles rely on it to function correctly. Nerves also need vitamin D to transmit messages between the brain and the rest of the body. Additionally, the immune system requires adequate vitamin D levels to effectively fight off infections, making it essential for overall health.
While the symptoms mentioned may indicate a D deficiency, repletion should only begin with verification of the blood vitamin D levels. Anything less than 20 ng/ml is listed as deficient and 21-29ng/ml is listed as insufficient.
How to Choose Vitamin D Supplements - Buying Guide
Here are the points to keep in mind when choosing the best vitamin D supplement for you.
Check the Dosage: 1,000 - 2,000 IU per Day for Most Healthy Adults
Despite the currently recommended daily intake for vitamin D being 600-800 IU/day for healthy adults, current research suggests a higher dose of1,000-2,000 IU per day. These guidelines are designed to prevent vitamin D deficiency in the general population. However, specific groups, such as children, pregnant individuals, adults over 75 years, and those with high-risk conditions, such as prediabetes, may require higher vitamin D intakes than these recommended daily allowances. The Endocrine Society suggests that these groups may benefit from increased vitamin D supplementation to meet their unique needs.
The Endocrine Society recommends a more aggressive approach for adults who are deficient in vitamin D. They advise taking 50,000 IU of vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol) weekly for eight weeks, or an equivalent daily dose of 6000 IU, to raise vitamin D levels in the blood quickly. Once adequate levels are reached, a maintenance dose of 1000–2000 IU daily is suggested to sustain those levels and prevent future deficiencies. This approach helps to ensure that individuals who start with low vitamin D levels can achieve and maintain optimal health.
Make Sure to Choose Vitamin D3 for the Most Effective Repletion
D3 shows a 25% higher bioavailability than D2 and is the most recommended form.
Choosing vitamin D3 is important because it is more effective than vitamin D2 at raising and maintaining adequate levels of vitamin D in the body. Vitamin D3 (cholecalciferol) is the form naturally produced by the skin when exposed to sunlight, making it more bioavailable and efficiently utilized by the body. Studies have shown that D3 improves and sustains vitamin D status over time, which is crucial for supporting bone health, muscle function, and the immune system.
Moreover, D3's stability ensures that the supplement remains potent and effective over time. D3 is often derived from animal sources, so it is particularly suitable for individuals without dietary restrictions. For those who require vegan options, plant-based D3 supplements are also available, offering the same efficacy as traditional D3 supplements. Choosing vitamin D3 ensures optimal health benefits and better overall maintenance of vitamin D levels.
Seek Out Supplements with Zinc or Vitamin K2 to Enhance the Absorption and Benefits of Vitamin D
Zinc and vitamin K2 enhance vitamin D’s ability to improve bone health by enhancing mineral absorption and directing calcium to bones and teeth.
Consider a vitamin D3 supplement with K2 or zinc if you want to maximize vitamin D's benefits for your bones, teeth, and overall health. While vitamin D3 helps your body absorb more calcium, vitamin K2 plays a crucial role in ensuring that this calcium is transported to your bones and teeth rather than accumulating in your arteries or other soft tissues. This combination can help improve bone density and prevent conditions like osteoporosis while also protecting your cardiovascular health.
If you are looking to enhance the effectiveness of vitamin D3 for immune support and overall cellular function, choosing a supplement that includes zinc is a smart option. Zinc is an essential cofactor for the activity of vitamin D-dependent genes, which helps vitamin D do its job more effectively. The interplay between zinc and vitamin D also supports zinc/vitamin D homeostasis, ensuring your body maintains balanced nutrient levels. Including zinc in your vitamin D3 supplement can thus enhance immune function, support vitamin D’s cellular function, and support numerous biological processes that rely on both nutrients.
If You're Vegan, Keep an Eye on Brands That Provide Plant-Based Options Like Sports Research
Plant-based vegan vitamin D3 supplements sourced from lichen algae have the same chemical structure as non-vegan supplements made from animal products like lanolin.
Check for plant-based D3 supplements if you follow a vegan or vegetarian lifestyle and want to ensure you’re getting an effective source of vitamin D. Unlike traditional vitamin D3, which is derived from animal sources like lanolin, plant-based D3 is sourced from lichen, a type of algae, making it suitable for those avoiding animal products. Brands like Sports Research offer vegan D3 supplements made from lichen, ensuring you can meet your vitamin D needs without compromising your dietary choices.
If you’re concerned about getting adequate vitamin D while adhering to a plant-based diet, checking for supplements that use lichen as the source of D3 is important. These plant-based options provide the same bioavailable form of vitamin D as animal-derived sources, supporting your bone health and overall well-being while aligning with your ethical or dietary preferences.
Oil-Based Capsules Offer More Concentrated Doses; Gummies for Difficulty Swallowing Pills
Opt for vitamin D capsules or softgels if you are looking for a more concentrated supplementation that is more readily absorbable. Capsules and softgels often contain higher doses of vitamin D, making them a more efficient option for those who need larger amounts to address deficiencies. They are also typically free of added sugars and flavorings, which might benefit those following a strict diet or managing health conditions like diabetes. Softgels, in particular, are easy to swallow and are usually made with a gelatine-based shell that allows for faster absorption, making them a practical choice for quick, effective supplementation.
Select vitamin D gummies if you prefer a tasty, easy-to-consume option that feels more like a treat than a supplement. Gummies are a great choice for those who have difficulty swallowing pills or who want to make their supplement routine more enjoyable. They are also a convenient option for children and adults sensitive to pill textures. While gummies provide an enjoyable way to take vitamin D, they may contain added sugars or flavorings, so it’s important to check the ingredients if you are watching your sugar intake.

Can You Take Vitamin D When Pregnant and Breastfeeding?
It is recommended that pregnant and breastfeeding mothers take a daily vitamin D supplement to support their own health and ensure their baby receives adequate amounts of this essential nutrient. Breastfed infants are particularly vulnerable to vitamin D deficiency due to breast milk's naturally low vitamin D concentration.
To meet their infants’ vitamin D requirements, mothers can provide a direct supplement to the baby or enrich their breast milk by taking daily or intermittent high-dose vitamin D supplements. The current recommendation for breastfed and partially breastfed infants is to receive 10 mcg (400 IU) of vitamin D daily, starting within the first few days of life.
For families who prefer not to give a supplement directly to their infant, high-dose maternal vitamin D supplementation can be an alternative. Daily maternal intakes of 100 mcg (4,000 IU) or more have been shown to meet the 10 mcg daily intake needed for the infant, depending on the mother's vitamin D status and the amount of breast milk consumed. Research indicates that high-dose maternal vitamin D supplementation (4000-6400 IU per day or a single monthly dose of 150,000 IU) can adequately enrich breast milk to meet infants’ needs without causing toxicity.
However, families need to discuss the risks and benefits of high-dose maternal supplementation with a healthcare provider, as factors such as obesity may require even higher dosages to achieve adequate vitamin D levels in breast milk.
The amount of vitamin D to take prenatally is based on serum vitamin D levels, with the goal being to maintain serum levels greater than 30-50 ng/ml. When serum levels are unavailable, daily amounts of 2,000 IU (up to 4,000 IU/day) should be maintained throughout pregnancy and lactation.
Research shows that for exclusively breastfed infants, mothers who receive 60,000 IU for ten days postpartum have infants with adequate vitamin D levels at six months.
