Today, 25(OH)D less than 12 ng/mL is considered evidence of severe
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.
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 ...
How Long Does It Take To Recover From Vitamin D Deficiency? It can take a few weeks for your vitamin D levels to rise once you start taking supplements. Expect a 4-6 week recovery time if you don't have any underlying health issues that could slow down the recovery phase.
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.
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. A systematic review of 23 different studies found similar associations between vitamin D deficiency and obesity.
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.
(Rickets; Osteomalacia) Vitamin D deficiency is most commonly caused by a lack of exposure to sunlight. Some disorders can also cause the deficiency. The most common cause is lack of exposure to sunlight, usually when the diet is deficient in vitamin D, but certain disorders can also cause the deficiency.
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.
In this longitudinal study of schoolchildren, vitamin D deficiency in middle childhood was associated with higher parent-reported externalizing problems scores such as higher aggressive and rule-breaking behaviors and internalizing problems scores such as anxiety disorders in adolescence.
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.
Vitamin and mineral deficiencies
Other vitamin deficiencies linked with muscle weakness include: calcium deficiency (hypocalcemia) potassium deficiency (hypokalemia) iron deficiency (anemia)
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.
The short answer is yes. Dizziness is a common symptom of vitamin D deficiency, along with fatigue and brain fog. If you are feeling dizzy all the time, it is worth checking your vitamin D levels. Insufficient vitamin D can cause dizziness because it plays a role in maintaining blood pressure and fluid balance.
Use of super-high dosing (eg, 50,000 to 2.604,000 IU/day) that result in vitamin D levels of 150 ng/mL and greater can lead to vitamin D toxicity with side effects that mimic MS relapse/progression, including muscle weakness and neuropsychiatric disturbances/psychosis.
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].
Vitamin deficiencies are a common cause of paresthesias. The B vitamins — vitamin B12 and vitamin B6 — are the most common ones. Deficiencies in copper, calcium, and magnesium can also lead to tingling in your hands and feet. Most of the time, correcting the deficiency can help reverse the symptoms.
Estrogen imbalance: Vitamin D deficiency may lead to lowered estrogen levels, which can cause depression, hot flashes, mood swings and more. Impaired immune system: Vitamin D deficiency may lead to an impaired immune system, putting women at an increased risk of infection and illness.
Humans with vitamin D deficiency exhibit muscle pain in muscles at multiple locations. However, the strongest association between vitamin D deficiency and pain is reported to occur in leg muscles (Heidari et al., 2010).
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.
