Signs of low vitamin D can show up in unexpected ways—from constant fatigue to mood swings and frequent illness. Maintaining optimal vitamin D levels is more than just a wellness trend—it’s essential for mood, immunity, bone health, and energy. Especially for women in the Northern US and UK, where sunlight is limited for most of the year, a vitamin D deficiency can quietly drain your vitality. In this guide, we’ll explore 7 signs you might be low on vitamin D, explain why it matters, and offer science-backed solutions, including supplement recommendations.

Why Vitamin D Matters So Much
Often referred to as the “sunshine vitamin,” vitamin D is essential for:
- Assisting with immune system support
- Increasing the absorption of calcium for healthy bones
- Improving mood and lowering symptoms of depression
- Increasing vitality and muscle performance
“Unfortunately, vitamin D deficiency affects nearly one in three people in regions with overcast conditions, such as the Northern US and the UK. The body finds it difficult to naturally produce enough of this essential nutrient when it isn’t exposed to adequate sunlight, particularly during the winter.”
According to the Cleveland Clinic, vitamin D deficiency is linked to fatigue, depression, bone loss, and a weakened immune system.
7 Signs You Might Be Low on Vitamin D
1. Constant Fatigue
Despite getting adequate sleep, do you still feel exhausted? Your cells’ energy centers, or mitochondria, function more effectively when vitamin D is present. Low levels indicate low vitality.
2. Frequent Illnesses
Getting ill too frequently? Immune protection requires vitamin D. Your body may become susceptible to infections, the flu, and colds if you have a deficiency.
3. Mood Swings or Depression
The production of the feel-good hormone serotonin is strongly correlated with vitamin D. Seasonal sadness, mood swings, and anxiety might be brought on by low levels.
4. Muscle Weakness or Pain
A low vitamin D level may be impairing neuromuscular function if your muscles feel abnormally weak or painful.
5. Bone Pain or Fragility
Calcium absorption is aided by vitamin D. Without it, bones weaken, making fractures and joint discomfort more likely.
6. Hair Thinning
Though less often, persistently insufficient vitamin D has occasionally been connected to alopecia and hair thinning.
7. Slow Wound Healing
Vitamin D facilitates healing and helps control inflammation. A deficiency may cause wounds, surgeries, or infections to take longer to heal.
How to Confirm a Vitamin D Deficiency
A blood test for 25-hydroxy vitamin D is the only reliable method. If you have more than one of the symptoms mentioned above, ask your doctor.
Ideal levels:
- 30–50 ng/mL = Sufficient
- Below 20 ng/mL = Deficient
What to Do If You’re Low on Vitamin D
1. Spend More Time in Sunlight
Several times a week, try to get 15 to 30 minutes of midday sunlight without wearing sunscreen. However, this might not be sufficient in the winter months in the Northern Hemisphere.
2. Add Vitamin D-Rich Foods to Your Diet
- Salmon and sardines
- Egg yolks
- Fortified cereals and milk
- Mushrooms exposed to sunlight
3. Take a High-Quality Supplement
Most adults can safely take 1,000–2,000 IU of supplements per day, though your doctor may recommend higher dosages.
