Many of us are at risk of becoming vitamin D deficient during this time of year when the days are shorter and we spend less time outside. According to research, one billion people worldwide are vitamin D deficient, which has serious implications for our health (more on which later).
It is well known that sun exposure is the simplest way to stimulate vitamin D production in the body, which is why we are especially vulnerable to deficiency during the dark winter months.
There are other ways to get our vitamin D fixed if we don’t have access to sunlight. “Most foods are poor sources of vitamin D, but those that include salmon, swordfish, tuna, full-fat dairy fortified with vitamin D, sardines, beef liver, cod liver oil, and egg yolks,” says Stephenson, emphasizing that eating such foods will not provide adequate levels but will help. She warns that vegans are particularly vulnerable to vitamin D deficiency.
Why is vitamin D good for the body?
Vitamin D levels must be optimal for overall health. “It regulates cellular growth and gene expression (essential for cancer prevention), improves cell differentiation, and is involved in immunity, fertility, muscle strength, hormone balance, sexual health, energy, mood, and other functions,” Stephenson explains. Simply put, it is necessary for overall health and well-being.
What happens if you’re vitamin D deficient?
A lack of vitamin D has an impact on both physical and mental health. We’ve all heard of osteoporosis, but low levels have also been linked to poor immunity, depression, and back pain, to name a few issues. “It’s linked to a variety of negative outcomes, including autoimmune conditions, Covid-19, and cancer, as well as general immunity, hormone health, and mood disorders,” says Stephenson. Vitamin D deficiency has also been linked to hypertension, diabetes, fibromyalgia, and neurological disorders such as multiple sclerosis.
What are the symptoms of vitamin D deficiency?
The only way to know for certain if you are vitamin D deficient is to have a blood test performed by your general practitioner. However, there are some warning signs and symptoms to be aware of.
Hair Loss
It is necessary for healthy hair that grows properly. Because a deficiency interferes with the life cycle of a follicle, it can cause hair loss or slow growth. Alopecia is also thought to be linked to a lack of vitamin D.
Depression, Anxiety, and Mood Disorders
According to scientific evidence, vitamin D may play an important role in mood regulation and lowering the risk of depression. Low levels have been linked to feelings of overwhelm, sadness, anxiety, forgetfulness, and sadness, and can contribute to seasonal affective disorder.
Bone and Muscle Pain
Some studies have found a link between a lack of vitamin D and frequent muscle pain and weakness. Meanwhile, bone and joint pain are common, as vitamin D is required for the body to absorb calcium; without it, fragility and pain may occur.
Fatigue
One of the most common symptoms of severe vitamin D deficiency is chronic, profound, or irreversible fatigue. Another symptom is insufficient sleep.
You’re Often Sick
A lack of vitamin D is linked to a weakened immune system. Consider getting a blood test if you’re frequently ill and don’t know why.
