Can vitamin D be harmful? Yes, getting too much vitamin D can be harmful. Very high levels of vitamin D in your blood (greater than 375 nmol/L or 150 ng/mL) can cause nausea, vomiting, muscle weakness, confusion, pain, loss of appetite, dehydration, excessive urination and thirst, and kidney stones.
Some people may need a higher dose, however, including those with a bone health disorder and those with a condition that interferes with the absorption of vitamin D or calcium, says Dr. Manson. Unless your doctor recommends it, avoid taking more than 4,000 IU per day, which is considered the safe upper limit.
The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Vitamin D toxicity might progress to bone pain and kidney problems, such as the formation of calcium stones.
However, taking too much vitamin D in the form of supplements can be harmful. Children age 9 years and older, adults, and pregnant and breastfeeding women who take more than 4,000 IU a day of vitamin D might experience: Nausea and vomiting. Poor appetite and weight loss.
In summary, long-term supplementation with vitamin D3 in doses ranging from 5000 to 50,000 IUs/day appears to be safe.
Tell your doctor right away if any of these signs of high vitamin D/calcium levels occur: nausea/vomiting, constipation, loss of appetite, increased thirst, increased urination, mental/mood changes, unusual tiredness. A very serious allergic reaction to this drug is rare.
Researchers believe that vitamin D may affect our shut-eye by interacting with the areas of the brain that regulate sleep. We also know that vitamin D plays a key role in supporting the immune system, and managing inflammation may support better sleep quality.
Because vitamin D toxicity can cause side effects like rapid heartbeat, confusion, restlessness and chest pains, it can potentially cause feelings associated with anxiety.
How Long Does It Take for Vitamin D to Work? If you have a vitamin D deficiency, you may notice improvements within 4-6 weeks of consistent supplementation. However, that timeframe can vary depending on what your baseline vitamin D levels are.
There are quite a few differences between vitamin D and vitamin D3, but the main difference between them is that vitamin D is a fat-soluble vitamin that regulates calcium and phosphorous levels in the body, whereas the vitamin D3 is the natural form of vitamin D produced by the body from sunlight.
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].
Yes, a vitamin D supplement can help reduce your stress. This is because vitamin D helps to regulate the production of cortisol. If you take a vitamin D supplement, it can help to reduce the amount of cortisol in your body and improve your stress response.
Vitamin D undergoes two hydroxylations in the body for activation. Calcitriol (1,25-dihydroxyvitamin D3), the active form of vitamin D, has a half-life of about 15 h, while calcidiol (25-hydroxyvitamin D3) has a half-life of about 15 days.
What's more, taking too much vitamin D can also negatively impact our health as well as our joint pain because our body simply can't cope! If toxic levels of vitamin D build up in the body it can interfere with your body's absorption of calcium.
For less frequent dosage, a higher amount is recommended. Overall, though, studies show that the best results come from taking vitamin D as part of a daily regimen, with dosage at the recommended level.
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.
Norman also lists 36 organ tissues in the body whose cells respond biologically to vitamin D. The list includes bone marrow, breast, colon, intestine, kidney, lung, prostate, retina, skin, stomach and the uterus. According to Norman, deficiency of vitamin D can impact all 36 organs.
Vitamin D serves several important functions in the body, including building strong bones and teeth and supporting immune health. Research suggests it also plays an important role in regulating energy levels and mood and may even help reduce the chance of certain diseases.
