If you are an older adult with vitamin D deficiency, you are at more risk of fractured (broken) bones due to low calcium levels and a weakened immune system. In cases of long-term vitamin D deficiency, you may develop osteoporosis or osteomalacia (soft bones in adolescents or adults, similar to rickets).
Vitamin D deficiency can lead to a loss of bone density, which can contribute to osteoporosis and fractures (broken bones). Severe vitamin D deficiency can also lead to other diseases: In children, it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend.
Not getting enough vitamin D may raise your risk for other diseases and conditions — some of them life-threatening.
Serum 25(OH)D, the hydroxy derivative of vitamin D and functional indicator of vitamin D status, has a reported half-life of approximately 20 to 30 d in humans; our observation that it took 3 wk for 25(OH)D concentrations (falling approximately 2 nmol/L daily) to reach a deficient state in reproductive age female mice ...
Recent studies have confirmed an association between cognitive impairment, dementia, and vitamin D deficiency.
Having inadequate levels of vitamin D may correlate with unintentional weight gain. A study on women over the age of 65 found that participants with a lower vitamin D level experienced more weight gain.
Levels of 12 ng/ml are too low and levels of 50 ng/ml are too high. High or low levels may affect a person's health. However, needs vary between individuals. The body depends on vitamin D for a variety of reasons, but it is especially important for bone health.
Levels of 50 nmol/L (20 ng/mL) or above are adequate for most people for bone and overall health. Levels below 30 nmol/L (12 ng/mL) are too low and might weaken your bones and affect your health. Levels above 125 nmol/L (50 ng/mL) are too high and might cause health problems.
Vitamin D levels change throughout the year. Your levels are highest in late summer and lowest at the end of winter. Healthy Bones Australia recommends a vitamin D level of at least 50 nmol/L at the end of winter and during summer higher levels are common in the range of 60-70 nmol/L.
Recent findings: Low vitamin D levels are associated with increased symptoms of depression and anxiety. For this reason, vitamin D screening should be performed in the prevention and treatment planning of these mood disorders.
Many studies show that overweight and obese people have low vitamin D levels when compared to their slimmer counterparts. And some studies link increased belly fat to vitamin D deficiency. In fact, according to a Medical News Today article, an increase in overall body fat and low vitamin D seem to go hand in hand.
Besides boosting mood and promoting calcium absorption, recent studies have shown that vitamin D may also aid in weight loss. For people with extra belly fat, a vitamin D supplement may be beneficial.
Vitamin D deficiency means you don't have enough vitamin D in your body. It primarily causes issues with your bones and muscles. Vitamin D is an essential vitamin that your body uses for normal bone development and maintenance.
The meta-analysis provided evidence that low vitamin D is cross-sectionally associated in adults with impaired episodic memory and executive dysfunction, especially mental shifting, informational updating and processing speed.
While too little vitamin D can cause brain fog, weakness, and frequent infections, taking too much in supplement form (overdosing on vitamins from food is unlikely) can cause dangerous adverse effects, including kidney failure, she explained.
The literature shows that vitamin D deficiency is a significant risk factor for ischemic stroke, with sun exposure, sex, age, race, diabetes, and genetics playing a role as well. Stroke severity and short- and long-term outcomes also worsen with vitamin D deficiency.
Magnesium is a critical factor in making Vitamin D bioavailable. Without magnesium present, Vitamin D is stored in the body and not used. The body depends on magnesium to convert Vitamin D into its active form within the body.

Caffeine has a mild diuretic effect, which leads to an increase in urination. As a result, water-soluble vitamins, such as B-vitamins and vitamin C can be depleted due to fluid loss. Research also demonstrated that the higher the level of caffeine, the more it interfered with vitamin D absorption.
Growing evidence has demonstrated that vitamin D has a role in sleep regulation [12]. Specifically, vitamin D deficiency (VDD) can increase risk of sleep disorders and is associated with sleep difficulties, shorter sleep duration, and nocturnal awakenings in children and adults [13,14,15].
If you find that you are more irritable than usual, it could be a sign of vitamin D deficiency. Without enough vitamin D, you may experience an increase in irritability and a decline in mood.
