Vitamin D Deficiency: Top 5 Symptoms
According to the National Institutes of Health, children ages nine and up need 1,300 mg of calcium per day to grow up healthy and strong. This is just one of the many reasons why you should order calcium supplement online. Vitamin D is similarly critical to a healthy body, as one of its primary roles is strengthening the immune system. Without it, you won't be able to avoid and fight off disease as well as you should. If you’re looking to order vitamin D supplements for you and your family, then you probably already know how important vitamin D is to your overall health. Unlike most vitamins, vitamin D works similarly to a hormone; this means every single cell throughout your body has receptors for it. However, vitamin D deficiency is quite common, especially during the winter or for people who work inside all day. A lack of vitamin D can show up in several ways because it directly effects several of your bodily systems. And likewise, when you order vitamin D supplements, you may see multiple benefits throughout your overall well-being. The following are five of the top most-common symptoms of vitamin D deficiency.

1. Fatigue or Tiredness

Although feeling tired all the time can have many different causes, a lack of vitamin D is one of the more common reasons for it. Interestingly, this potential cause is frequently overlooked. Different case studies have demonstrated that extremely low levels of vitamin D in the bloodstream can cause fatigue so bad that it significantly lowers one’s quality of life. However, even moderately low levels of vitamin D can have an impact on your overall energy. While sleep aid supplements can be helpful for improving your night’s sleep and boosting daytime energy, you may just need to order vitamin D supplements to get rid of your chronic tiredness and fatigue.

2. Frequent Sickness and Infections

As noted above, keeping your immune system healthy and strong is one of vitamin D’s core roles in your body. Vitamin D interacts directly with all the cells responsible for fighting off infections. Without it, your immune system is compromised, weakened, and unable to effectively protect your body from dangerous and unpleasant illnesses. If you frequently become sick, and especially if you often contract colds or the flu, it may be a sign of vitamin D deficiency. Multiple large-scale studies have also shown connections between vitamin D deficiency and illnesses like pneumonia and bronchitis. Fortunately, this cause may be avoidable altogether when you order vitamin D supplements. Different studies show that taking a daily dosage of up to 4,000 IU might lower your risk of contracting infections in the respiratory tract. If you work in a hospital or school, taking vitamin D supplements is vital to help avoid infections and illnesses.

3. Back or Bone Pain

Vitamin D can help support the health of your bones in multiple different ways. It does this partly by helping your body absorb more calcium, which is essential for strong, healthy bones. Pain in your bones or in your lower back can be signals of lower-than-normal levels of vitamin D in your body. Multiple studies have shown connections between lower back pain and too-low vitamin D levels. Even worse, at least one controlled study has demonstrated a connection between vitamin D deficiency and bone pain in ribs, joints, and legs. It's no wonder people who suffer from chronic pain might order vitamin D supplements regularly.

4. Slower Wound Healing

When wounds from injury or surgery take a long time to heal, it may also be a symptom of vitamin D deficiency. Multiple studies have shown that aspects of healing are compromised when levels of vitamin D in the blood aren’t high enough. This can be partly because vitamin D boosts the production of compounds which help form new layers of skin during wound healing. It may also be because vitamin D helps to control inflammation and fight infection, which are both critical for effective healing.

5. Depression

Studies have suggested that depressed moods can result from a vitamin D deficiency, especially in older adults. While some people may feel dejected from time to time, long-term mental health issues can be exacerbated by the lack of vital supplements like vitamin D. This also includes seasonal depression, as it’s been found that providing vitamin D supplements to people with the deficiency during the colder months tended to boost their mood.


These are just a few of the many ways vitamin D is essential for your health, and how your health can suffer when vitamin D levels are too low. To help combat these and other symptoms of vitamin D deficiency, order vitamin D supplements and begin taking them regularly. For more information, don't hesitate to reach out to FitFormula today at
