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.
Research from 2019 found a strong association between chronic constipation and vitamin D deficiencies. The participants with intestinal disorders that cause constipation had lower levels of vitamin D.
Vitamin D functions in the digestive system to:
Help regulate calcium absorption. Important for absorption of magnesium, phosphate, iron and zinc. Protect the gut by influencing immune cell function and regulating inflammation. Enhance the diversity and richness of the microbiome, and increase healthy bacteria in the ...
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.
Supplements such as magnesium, fiber, probiotics, and senna may be particularly helpful.
CONCLUSION. Vitamin D deficiency, anxiety and depression symptoms are commonly associated with chronic functional constipation induced by intestinal motility disorders. Vitamin D serum levels should be routinely measured in these patients.
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.
The cause of IBS is unknown, although it's believed that certain foods, stress, and hormonal changes may trigger symptoms. Recent research also suggests a possible connection between vitamin D and IBS. There appears to be a higher prevalence of IBS among people with a vitamin D deficiency.
Increased levels of vitamin D and calcium in the body can contribute to several digestive issues like stomach pain, constipation and diarrhea. These can be the signs of other health issues as well, therefore it is important to inform your doctor if you are taking any supplements.
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.
Taking large doses of vitamin C can cause diarrhea. Other supplements which can cause diarrhea when taken in high doses include ashwagandha, NAC (N-acetyl-cysteine), lysine, iodine and kelp supplements which contain iodine, D-limonene, and yacon syrup.
While the best timing has not been established, scientific data to confirm anecdotal reports that supplementing at night may interfere with sleep is unavailable. Current research suggests you can fit vitamin D into your routine whenever you prefer.
While Vitamin D supplements may be taken, be careful not to overdo it. Too much of this fat-soluble vitamin can cause nausea, vomiting, itching, weakness, confusion, heart rhythm problems and kidney damage.
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.
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.
Vitamin D supplementation significantly increased gut microbial diversity. Specifically, the Bacteroidetes to Firmicutes ratio increased, along with the abundance of the health-promoting probiotic taxa Akkermansia and Bifidobacterium.
The vitamin D that is consumed in food or as a supplement is absorbed in the part of the small intestine immediately downstream from the stomach. Stomach juices, pancreatic secretions, bile from the liver, the integrity of the wall of the intestine — they all have some influence on how much of the vitamin is absorbed.
The effect of equivalent oral doses of vitamin D3 600 IU/day, 4200 IU/week and 18,000 IU/month on vitamin D status was compared in a randomized clinical trial in nursing home residents. A daily dose was more effective than a weekly dose, and a monthly dose was the least effective.
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.
Extra amounts of water-soluble vitamins are typically excreted. The fat-soluble vitamins A and D are the most likely to cause toxicity symptoms if you consume them in high amounts.
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.
Vitamin D is not believed to affect anxiety directly. Though it may be correlated with higher anxiety levels, there are likely reasons beyond the vitamin itself - reasons that will be discussed later in this article. Historically, seeing the sun was often a cause for celebration and happiness.
