Most people don't experience side effects with vitamin D, unless too much is taken. Some side effects of taking too much vitamin D include weakness, dry mouth, nausea, vomiting, and others.
“If one is deficient then weekly dose is better but if one wants to maintain the level, then a daily dose of 800 international unit (iu) is recommended. Also taking the sachet once a month if one has normal levels of Vitamin D, helps maintain that level.”
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.
“Most patients who require vitamin D supplements should take a small daily dose,” Nate Wood, MD, Instructor of General Medicine at Yale Medicine, told Health. “For patients who are severely deficient in vitamin D, a larger weekly dose may be prescribed for the short-term.”
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 side effects of taking too much vitamin D include weakness, dry mouth, nausea, vomiting, and others. Taking vitamin D for long periods of time in doses higher than 4000 IU (100 mcg) daily is possibly unsafe and may cause very high levels of calcium in the blood.
Oranges are one of the fruits rich in Vitamin D as its juice is fortified with calcium & vitamin D. This is one of the best sources of vitamin D for people who are lactose intolerant and cannot include milk & dairy products in their diet.
It is not necessary to take vitamin D every day. If you need to take vitamin D because your blood levels are low, you can take it every few days, weekly, or even monthly, because, as you mention, it is fat-soluble and, therefore, stored for future use within the fat in your body.
For people who've been ingrained with the one-a-day-concept as the sensible way to take supplements, nutrition experts say vitamin D is a forgiving vitamin, and many different approaches work equally well. People can pop a lot at once, even a week's worth at a single sitting, with no adverse effects.
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.
If you are taking a supplement for a true deficiency, such as a low iron, B12, folic acid or vitamin D, then you should consult your doctor before making any changes. But Dr Fenton added: “If however, you have been taking general vitamin supplements, it is absolutely fine to just stop.
That means your body can mobilize its own reserves if your daily intake falters temporarily — but it also means that excessive doses of vitamin D can build up to toxic levels. At those extremes, vitamin D can raise blood calcium to levels that can cause grogginess, constipation, and even death.
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].
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.
There's no set time of day that's best to take vitamin D supplements. Some people say taking vitamin D supplements at night is an insomnia risk. There's no research to confirm this, but you might want to take your supplement earlier in the day if you think it's screwing with your sleep.
When vitamin D levels are low and the body isn't able to properly absorb calcium and phosphorus, there is an increased risk of bone pain, bone fractures, muscle pain and muscle weakness. In older adults, severe vitamin D deficiency (levels less than 10 ng/mL) may also contribute to an increased risk of falls.
Does Vitamin D Deficiency Make You Tired? Yes, if you're not getting enough vitamin D you will likely experience low energy and feel tired. An observational study, this one in 200 female nurses, found that only 9.5% of them had normal vitamin D levels, while 89% were found to have vitamin D deficiency.
