Vitamin D: Benefits, risks, deficiency, and how to get enough
Vitamin D is a fat-soluble vitamin essential for bone and immune health. It belongs to a group of compounds that includes vitamins D1, D2, and D3.
Your body produces vitamin D naturally when your skin is exposed to sunlight, but you can also get it from certain foods and supplements.
Vitamin D plays several key roles in the body as follows:
- Supports the absorption of calcium and phosphorus
- Promotes strong bones and teeth
- Helps regulate the immune system
- May improve resistance to infections and diseases
Health Benefits of Vitamin D
Research suggests vitamin D may help:
- Lower the risk of multiple sclerosis (MS)
- Reduce heart disease risk, including hypertension and stroke
- Prevent severe respiratory infections, including flu and possibly COVID-19
- Support immune health, lowering the risk of autoimmune conditions like type 1 diabetes and rheumatoid arthritis
May Regulate Mood and Reduce Depression
Studies show a link between vitamin D and improved mood. Supplementation may ease symptoms in people with:
- Depression
- Anxiety
- Fibromyalgia
May Support Weight Loss
People taking vitamin D and calcium supplements have reported more weight loss than those on placebos, possibly due to reduced appetite. However, the connection between vitamin D and weight is still being studied.
You may be at risk if you:
- Live in high-pollution areas
- Use sunscreen often
- Stay indoors frequently
- Have darker skin
- Live in cities with limited sunlight exposure
Symptoms of deficiency include:
- Fatigue and muscle aches
- Bone pain or weakness
- Frequent fractures, especially in legs or hips
A blood test can confirm deficiency, and doctors may recommend supplements or high-dose treatments.
While sunlight and food rarely cause overdose, excessive supplementation can raise calcium levels, leading to:
- Nausea, vomiting
- Abdominal pain
- Confusion and dehydration
- Frequent urination and extreme thirst
Getting enough vitamin D is crucial for maintaining bone strength, preventing diseases, and promoting mental health.
Sun exposure, diet, and supplements can help maintain healthy levels. However, always consult a healthcare provider before starting supplementation, especially in high doses.
