We all know that Vitamin D is important for bone density, but it is also an important nutrient for many important functions in the body that are often overlooked. Even active people who are outside every day can experience symptoms of Vitamin D deficiency, and it is actually very common for individuals to be low in this nutrient - sometimes even while supplementing with Vitamin D! Below are some of the most common symptoms related to Vitamin D deficiency.
1. Fatigue
Vitamin D is needed by the body to create energy by the mitochondria. Without adequate Vitamin D levels, you can end up feeling tired for the majority of your day. This tiredness can lead to a lack of energy and motivation, which may impair your overall health.
2. Bone and Back Pain
Vitamin D well known for it's involvement in maintaining bone health through a number of mechanisms. It improves your body's absorption of calcium, and with the help of Vitamin K2 directs that calcium into your bones to maintain adequate bone density and prevent osteoporosis. Bone pain or frequent stress fractures may be signs of inadequate vitamin D.
3. Depression
Vitamin D helps your brain’s neurotransmitters produce serotonin, which affects our feelings of happiness. Studies have linked low levels of vitamin D with episodes of depression.
4. Chronic Illness
The immune system requires a healthy amount of Vitamin D to be able to fight off infections and disease. A lack of Vitamin D can make you more susceptible to illness, and may delay your ability to recover from the common cold or flu.
5. Inability to Lose Weight:
Vitamin D deficiency can interfere with the function of the leptin, the hormone that signals the brain you are full. Without proper activation of leptin, it is much harder to stop eating and to resist cravings. Studies have found a strong correlation between Vitamin D deficiency and obesity.
"Normal" Vitamin D levels currently range from 30-100 ng/ml while research has shown a much narrower window to be ideal. It is recommended you check with a trained health care provider to maintain optimal levels of Vitamin D.
