Choosing the Best Vitamin D Supplement for Your Health If you choose to go the supplement route, Clifford recommends taking around 400 to 800 IU of vitamin D3 (cholecalciferol) per day. “Vitamin D3 is the form that is already stored in the body, so some studies have found it to be more effective,” Clifford says.
A meta-analysis of randomized controlled trials that compared the effects of vitamin D2 and D3 supplements on blood levels found that D3 supplements tended to raise blood concentrations of the vitamin more and sustained those levels longer than D2. [76,77] Some experts cite vitamin D3 as the preferred form as it is ...
“Vitamin D3 cholecalciferol is the most absorbable and potent form, [whereas] Vitamin D2 (ergocalciferol) is typically plant-based and not as effective at raising vitamin D levels in the body and thus is not recommended as often,” she explains.
Studies have shown that vitamin D3 supplements may be superior in raising the body's vitamin D stores. There are many health benefits to vitamin D supplementation, but your doctor should use lab tests to recommend the amount of vitamin D you should take and which form.
Half of the study's participants received a dose of 50,000 IU of vitamin D3 every two weeks for six months. The other half were given a placebo. On top of major increases in vitamin D levels, participants also reported significant improvements in their IBS symptoms.
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.
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.
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.
In our study, the microencapsulated form of vitamin D was the most bioavailable.
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.
What to look for in vitamin D supplements. In supplements, two forms of vitamin D are available: D2, called ergocalciferol, and D3, called cholecalciferol. Both are effective, but D3 seems to be more effective at higher dosages.
The health of your gut.
Therefore, conditions that affect the gut and digestion, like celiac disease, chronic pancreatitis, Crohn's disease, and cystic fibrosis, can reduce vitamin D absorption.
Studies have repeatedly shown that vitamin D3 is superior at raising levels of vitamin D in the body. These findings were supported by a recent review of the evidence which found that vitamin D3 supplementation increased vitamin D levels in the body better than vitamin D2.
Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys.
People considering starting a Vitamin D3 regimen without the advice of a doctor should consider supplementing with magnesium as well to prevent the adverse effects of unabsorbed calcium.
With a meal: Vitamin D is a fat-soluble vitamin. This means it does not dissolve in water. Your body absorbs Vitamin D better when it is consumed with healthy fats, such as avocados, nuts, eggs, and seeds. Taking your supplement with breakfast or lunch is recommended, or you can even take it with an afternoon snack.
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.
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.
Vitamin D is vital for making our muscles work efficiently and boosting energy levels, new research from Newcastle University has shown.
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.
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].
What causes vitamin D deficiency? In general, the two main causes of vitamin D deficiency are: Not getting enough vitamin D in your diet and/or through sunlight. Your body isn't properly absorbing or using vitamin D.
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.
