Signs of an allergic reaction, like rash; hives; itching; red, swollen, blistered, or peeling skin with or without fever; wheezing; tightness in the chest or throat; trouble breathing, swallowing, or talking; unusual hoarseness; or swelling of the mouth, face, lips, tongue, or throat.
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.
Calcium overdose can impair the functioning of the kidneys, increase the pH of the blood, and can cause nausea and vomiting, confusion or changes in thinking or mentation, itching, and in extreme cases irregular heartbeat. Vitamin D overdose can contribute to high levels of calcium in the blood.
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.
Vitamin D deficiency is associated with the risk of psoriasis and atopic dermatitis, and several clinical/observational studies have suggested the beneficial effect of vitamin D in the therapy of these 2 inflammatory skin disorders.
Taking too much colecalciferol over a long period of time can cause a skin rash. It can also cause high levels of calcium. Too much calcium in your body (hypercalcaemia) can cause stomach pain, weaken your bones and damage your kidneys and heart.
The intake of pharmacologic doses (much higher than the recommended daily allowance -RDA) of niacin or related compounds is known to induce facial flushes and/or facial erythema. Other skin reactions from vitamin B3 compounds include itching, dry skin, dermatitis, hives, sore mouth, dry hair, and acanthosis nigricans.
But how do you flush vitamin D out of your system – and can you even do that? Yes, by ensuring you consume plenty of water. This will encourage urination, allowing your body to shed the excess vitamin D and calcium more quickly. Prescription diuretics like furosemide can also be helpful.
While it is possible to take enough vitamin D once a week to keep yourself balanced, the best results were found to be a lower dose (1,000-2,000 IUs or 25-50 mcg ) taken daily. Taking vitamin D consistently with a meal containing healthy fats will ensure that your body absorbs it properly.
There is no simple answer as to the amount of time it takes vitamin D to leave the body. However, with the knowledge that calcidiol provides the best indication of vitamin D levels, it can be asserted that in a time period of 15 days, your body will deplete half of its supply of serum vitamin D.
Skin rashes
You may experience red, dry and itchy skin due to vitamin D deficiency. Intake of vitamin D can help you treat such skin problems. It can also reduce skin rashes. Vitamin D is also beneficial for treating eczema which is also a skin condition.
Dry skin: Your body loses moisture at night, which can make your skin itchy. Hormonal changes: At night, your body doesn't produce as many hormones as it does during the day and certain hormones reduce inflammation (swelling). As you have fewer hormones at night, your skin could be itchy.
And some will find that taking vitamin D supplements makes them feel worse; probably because the high PTH turns the supplements into high concentrations of 1, 25 dihydroxy vitamin D which is the active form, causing symptoms of vitamin D toxicity. When taking vitamin D makes you feel worse, you should immediately stop.
The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years.
Mayo Clinic recommends that adults get at least the RDA of 600 IU. However, 1,000 to 2,000 IU per day of vitamin D from a supplement is generally safe, should help people achieve an adequate blood level of vitamin D, and may have additional health benefits.
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.
If your blood levels are exceptionally low, you may need higher doses that should be used under the direction of a healthcare provider. In patients with vitamin D levels less than 20 ng/mL, start with 50,000 IUs of vitamin D3 once a week for 6 to 8 weeks.
If you've been prescribed high-dose vitamin D, work closely with your doctor to monitor your blood levels. It can take three months or more to bring them back up, but once they're good, you can stop the high doses and return to a lower vitamin D supplement for maintenance.
Symptoms of too much vitamin D
The symptoms include: Increased thirst. Frequent urination.
Allergic Reactions
This occurs when your body mistakenly recognizes the vitamin D-3 as a potentially harmful chemical and mounts an immune response against it. Mild allergic reactions can cause rashes, hives and nasal congestion, while more severe reactions can affect your ability to breathe and even prove fatal.
