Taking vitamin D can increase levels of calcium in the blood, and too much calcium can cause side effects. If you take large doses of vitamin D, you may experience stomach pain, loss of appetite, constipation, or diarrhea as a result of elevated calcium levels.
Constipation is a possible side effect of taking too much vitamin D3 (the form of D that the body produces from sunlight). According to the National Institutes of Health's Office of Dietary Supplements, the maximum daily amount of vitamin D3 that people should consume is: 1,000 to 1,500 IU for infants.
Too much or too little of necessary nutrients, such as vitamin D, can cause significant health problems. That being said, when you intake excess or toxic levels of vitamin D, you may experience constipation, in addition to other digestive problems, loss of appetite, and muscle weakness.
Vitamin D
The participants with intestinal disorders that cause constipation had lower levels of vitamin D. These findings do not suggest that increasing vitamin D will relieve constipation, however, as the low vitamin D levels may be a consequence of chronic constipation.
Try taking it alongside breakfast or with a bedtime snack — as long as it doesn't interfere with your sleep. The key is to find what works for you and stick with it to ensure you're meeting your vitamin D needs. Taking vitamin D with a meal can increase its absorption, but studies on specific timing are limited.
Vitamin D Provides Benefits to Our Digestive Health
Vitamin D levels correlate with intestinal motility. In patients with stomach paralysis from inflammatory enteric neuropathy, the correction of vitamin D deficiency improved gastrointestinal motility and related symptoms.
Interactions. Possible interactions include: Aluminum. Taking vitamin D and aluminum-containing phosphate binders, which may be used to treat high serum phosphate levels in people with chronic kidney disease, might cause harmful levels of aluminum in people with kidney failure in the long term.
Taking vitamin D can increase levels of calcium in the blood, and too much calcium can cause side effects. If you take large doses of vitamin D, you may experience stomach pain, loss of appetite, constipation, or diarrhea as a result of elevated calcium levels.
We recommend taking it with a source of quality fat in the morning or when you break your fast. Avoid taking vitamin D in the evening (we'll talk about why below). Since vitamin D is a fat-soluble vitamin—meaning it doesn't dissolve in water—your body can most easily absorb it when you take it with food.
Vitamins in general won't cause constipation, but certain components, such as calcium and iron, can be a problem. "I would tell a patient to stop taking the iron [or calcium] unless they really need it and, if they do need it, I would put them on a stool softener to counteract that," says Dr.
IBS and Vitamin D deficiency
Symptoms include a combination of diarrhoea or constipation, bloating, urgency (the need to use a restroom in a hurry), white or yellow mucus in the stool and the sensation of incompletely passing stools.
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(OD)D by 10 ng/ml after a few weeks.
Despite these findings, the current body of research suggests that consuming higher amounts of vitamin D has little effect on weight gain or loss. Still, more studies differentiating between body weight and body fat may be needed to properly evaluate this effect ( 7 , 8 , 9 , 10 ).
Increasing serum vitamin D levels even higher produced greater colorectal cancer preventive benefits. Lead researcher Edward Gorham, Ph. D. explained, “We project a two-thirds reduction in incidence with serum levels of 46 ng/ml, which corresponds to a daily intake of 2,000 IU of vitamin D3.
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.
Vitamin D undergoes further chemical changes, first in the liver and then in the kidneys, to become calcitriol. Calcitriol acts on the intestine, kidneys, and bones to maintain normal levels of blood calcium and phosphorus.
2. Vitamin D may regulate mood and reduce depression. Research has shown that vitamin D might play an important role in regulating mood and decreasing the risk of depression. A review of 7,534 people found that those experiencing negative emotions who received vitamin D supplements noticed an improvement in symptoms.
Is there a benefit to taking vitamin D at night? There's been some buzz suggesting a link between supplementing with vitamin D before bedtime and the ability to drift off to dreamland. Some studies have shown that vitamin D is connected to the production of melatonin, which regulates circadian rhythm and drives sleep.
No interactions were found between caffeine and Vitamin D3.
In very high doses, many minerals (like iron) and vitamins can harm your body. Current guidelines say adults shouldn't take more than the equivalent of 100 micrograms a day. But vitamin D is a 'fat-soluble' vitamin, so your body can store it for months and you don't need it every day.
Health problems such as irritable bowel syndrome, celiac disease, and inflammatory bowel disease like Crohn's disease can interfere with the absorption of vitamin D. Surgeries that remove or bypass part of the stomach or intestines, such as gastric bypass, can also lead to low vitamin D.
Our results have shown that 6 weeks supplementation with Vitamin D improves the symptoms and QOL in patients with IBS. It seems that Vitamin D supplementation improves the IBS characteristics through improving the factors involved in the development of IBS.
If you're not getting enough vitamin D, a vitamin D deficiency could be the cause of gas and gas-related bloating. In fact, one study showed that people who increased their levels of vitamin D had fewer gastrointestinal issues overall.
