Vitamin D Deficiency Is Incredibly Common

Vitamin D is an extremely important vitamin that has powerful effects on several systems throughout your body including your immune system and brain. Vitamin D deficiency is very common. It’s estimated that over 1 billion people worldwide have low levels of the vitamin in their blood.

According to a recent study, 42% of adults in the US are deficient. This number goes up to 70 % in Hispanics and 82% in African-Americans. We see vitamin D deficiency in our practice on a daily basis with test numbers well below 20 (normal 20-80). Vitamin D supplementation is a safe and effective way to support health and wellness.


Signs and Symptoms of Vitamin D Deficiency

  1. Increased Frequency of Illness
    • Vitamin D directly interacts with the cells that are responsible for fighting infection.
    • Vitamin D plays important roles in immune function. One of the most common symptoms of deficiency is an increased risk of illness or infections.
  2. Chronic Fatigue and Tiredness
    • Observational study in female nurses found a strong connection between low vitamin D levels and self-reported fatigue.
    • Researchers found that 89% of the nurses were deficient.
    • Excessive fatigue and tiredness may be a sign of vitamin D deficiency. Taking supplements may help improve energy levels.
  3. Bone and Back Pain
    • Vitamin D helps maintain bone health facilitating calcium in the bone.
    • Low blood levels of vitamin D may be a cause or contributing factor to bone pain and lower back pain.
  4. Depression
    • A depressed mood may also be a sign of vitamin D deficiency.
    • Depression is associated with low vitamin D levels and some studies have found that supplementing improves mood.
  1. Impaired Wound Healing
    • Slow healing of wounds after surgery or injury may be a sign that your vitamin D levels are too low.
    • Inadequate vitamin D levels may lead to poor wound healing following surgery, injury or infection.
  2. Bone Loss
    • Vitamin D plays a crucial role in calcium absorption and metabolism.
    • Many older people who are diagnosed with bone loss believe they need to take more calcium. However, they may be deficient in vitamin D as well.
    • A diagnosis of low bone mineral density may be a sign of vitamin D deficiency. Getting enough of this vitamin is important for preserving bone mass as you get older.
  3. Hair Loss
    • Alopecia areata is an autoimmune disease characterized by severe hair loss from the head and other parts of the body. It’s associated with rickets, which is a disease that causes soft bones in children due to vitamin D deficiency.
    • Hair loss may be a sign of vitamin D deficiency in female-pattern hair loss or the autoimmune condition alopecia areata.
  4. Muscle Pain
    • The vitamin D receptor is present in nerve cells called nociceptors, which sense pain.
    • There is a link between chronic pain and low blood levels of vitamin D, which may be due to the interaction between the vitamin and pain-sensing nerve cells.
