If you take too much supplemental or prescription vitamin D, it can lead to vitamin D toxicity. The main complication of this is moderate to severe hypercalcemia, which can cause symptoms like vomiting, increased thirst and frequent urination.
High vitamin D levels also can cause nausea, vomiting, muscle weakness, confusion, loss of appetite, dehydration and frequent urination.
When taken by mouth: Vitamin D is likely safe when taken in recommended amounts. 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.

Thirst is normally just the brain's way of warning that you're dehydrated because you're not drinking enough fluid. But excessive and persistent thirst (known as polydipsia) could be a sign of an underlying problem such as diabetes.
According to the National Institutes of Health, vitamin D promotes calcium absorption in the gut and helps regulate the concentration of calcium and phosphorus in the blood, which supports building and maintaining healthy, strong bones and helps regulate skeletal and neuromuscular function.
Together with calcium, vitamin D also helps protect older adults from osteoporosis. Vitamin D has other roles in the body, including reduction of inflammation as well as modulation of such processes as cell growth, neuromuscular and immune function, and glucose metabolism [1-3].
A study found that higher serum vitamin D levels were associated with a reduced risk of weight gain in normal weight adults [10]. Another study reported that subjects who gained ≥5% weight had lower vitamin D levels than subjects who lost >5% weight [11].
Examples of medications that cause dry mouth are oxybutynin ER (Ditropan XL), diphenhydramine (Benadryl), and Adderall (amphetamine salts). If you're experiencing dry mouth, it's recommended to talk to your pharmacist or healthcare provider. They can help you find a treatment plan that addresses or fixes your symptoms.
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.
They may do a blood test to check your levels of vitamin D. "The blood test will tell us whether you're within normal ranges of vitamin D or whether it's too low," says Dr. Lacey. Call 800.922.0000 to make an appointment with a primary care provider.
Although this might sound similar to relieving stress, strong levels of vitamin D not only correlate with reduced stress – it also improves the production of “feel good” hormones. Vitamin D actively fights depression by increasing serotonin, the hormone key to stabilising mood and increasing happiness.
So, when it comes to vitamin d deficiency treatments, how long till you start to feel better? Those with the lowest levels should feel an improvement after just a few days, while those who only need to top up their levels may have to wait a week or two before they begin to feel healthier and more energised.
Official answer. Generally, it takes a few weeks of taking daily vitamin D supplements for vitamin D levels in the body to rise. Each 1,000 IU of vitamin D3 taken daily is expected to raise blood levels of 25(OH)D by 10 ng/ml after a few weeks.
Too much vitamin D can cause harmful high calcium levels. 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.
However, vitamin D then needs to be converted to its active form (calcitriol, also called 1,25-dihydroxycholecalciferol or 25(OH)D). After taking a high dose of vitamin D3, a study showed it can take approximately seven days for it to convert and cause a peak in 25(OH)D levels, the form tested by your doctor.
Dehydration. Dehydration means your body doesn't have enough water to carry out normal tasks, and thirst is the main symptom. It can happen for a lot of reasons, such as exercise, diarrhea, vomiting, and too much sweating.
Anemia can cause thirst. When you have anemia your body struggles to produce enough healthy red blood cells [2]. A variety of different things can cause anemia such as a poor diet or another disease. When you have serious signs of anemia, it can make you feel thirsty, dizzy, tired, and weak.
For instance, eating a particularly salty or spicy snack or meal just before bed can cause thirst that's temporary, but intense — potentially intense enough to wake you up. Additionally, alcohol and caffeine can dehydrate your mouth, so it's best to limit both before going to bed to avoid dry mouth.
It's also likely that you'll feel thirsty all the time and have a "dry" feeling that's always present, no matter how much water you drink. If you need to pee regularly and always feel thirsty, your sleeping patterns and daily activities may be disrupted.
