Magnesium is a major mineral in your body and is found in more than 300 enzyme systems. It’s essential for regulating various biochemical functions in the body, as well as for bone health, heart health, and more. You can get magnesium through an array of magnesium-rich foods, such as almonds, green leafy vegetables, and peanuts. And you can also boost your magnesium intake by taking a magnesium supplement.
Magnesium citrate is one of the most popular magnesium supplements now on the market. It’s a form of magnesium that’s bound with citric acid. Citric acid is naturally found in citrus fruits.
What may set magnesium citrate apart from other magnesium supplements is its known laxative-like properties. There’s also some research to suggest that magnesium citrate might be among the more bioavailable forms of magnesium.
Magnesium citrate is especially popular for its potential use as a laxative. Indeed, physicians will often recommend this supplement as part of a colonoscopy preparation plan. One study looked at the effect of taking magnesium citrate and sodium phosphate in preparation for a colonoscopy and found that these supplements did help encourage bowel movements. Another study likewise found that magnesium citrate combined with a laxative helped clear the bowels for a colonoscopy. There are good reasons to believe that magnesium citrate helps support healthy bowel movements.
When taking supplements, it’s important to remember that everybody’s different. A supplement’s effectiveness often depends on the person and the dose being used.
With that said, people taking magnesium citrate usually notice changes in bowel movements in a fairly short time – sometimes within minutes, sometimes within hours. A liquid magnesium citrate supplement may work more quickly than a capsule form.
Milk of magnesia is magnesium hydroxide, which is commonly found in some antacids. Magnesium hydroxide and magnesium citrate are both sometimes taken for their laxative-like effects.
Both milk of magnesia (magnesium hydroxide) and magnesium citrate can work within the same timeframe, sometimes between 30 minutes and 6 hours. The speed with which they work can depend on a variety of factors, including the individual person taking the supplement, the dose, and the form of supplementation (liquid, capsules, softgels, and so on).
However, when it comes to colonoscopy prep, studies have found milk of magnesia to be less effective overall.
Most any supplement you take will have the potential for some side effects. While most people who take magnesium citrate don’t experience any side effects, some do report some digestive discomfort. Magnesium supplements can also interact with other medications you may be taking. It’s best to check with your doctor before changing your supplement routine.
If you’re experiencing occasional constipation, magnesium citrate may be able to help this problem. Talk to your doctor about your particular situation and see if a magnesium citrate supplement might be right for you. Studies clearly show that this supplement can help with bowel movements.
When getting ready for a colonoscopy, always talk to your doctor about the recommended preparation. Of course, you’ll want to make sure you’re clearing your system properly.
Studies have shown that magnesium citrate can help with colonoscopy preparation by helping with bowel movements. Still, people with kidney or digestive issues should use caution before adding a magnesium supplement.
You can also strive to maintain healthy bowel movements by eating a balanced diet that includes fiber, fruits, veggies, and hydration, and by getting enough exercise and movement.
Magnesium citrate is a form of magnesium supplement that’s commonly used to support bowel movements. It’s magnesium combined with citric acid, which is what you naturally find in citrus fruits. Some studies show that magnesium citrate can be helpful for those times when you’re preparing for a colonoscopy.
Magnesium supplements in general boast a range of health benefits, since magnesium is a mineral that serves many functions in your body. Care/of’s magnesium – dubbed “The Dream Weaver” – can support bone health and improve sleep. It’s not magnesium citrate, but it might do the trick.
