I have a family history of colon cancer and am often asked about prevention. Recommending magnesium supplementation will be an excellent option if it is tolerated (does not cause diarrhea).

Not only magnesium reduces colon cancer risk, magnesium supplementation can also help lower high blood pressure, decrease the symptoms of PMS, lower the risk of developing diabetes, help depression, anxiety and reduce migraine symptoms. Magnesium has been shown to help muscle cramps, constipation, kidney stones, fibromyalgia, osteoporosis, insomnia, and asthma. magnesium is also needed for calcium to be used by bone.

I had recently read the Pre-eclampsia webinar. It’s great to find out that magnesium has so many benefits and it is in many people’s diets. This will be a great natural option for prevention of colon cancer. Magnesium supplementation can be an addition to other preventative measures such as exercise.

Magnesium is also essential for the proper functioning of the heart. it's role in preventing heart disease and strokes has been proven. Numerous double-blind studies have showing its beneficial effects for many types of arrhythmias as well as in angina due to either a spasm of the coronary artery or atherosclerosis.

The one thing all of these (magnesium, probiotics, psyllium) all have in common is that reduce constipation and colonic transit time. That means that anything in your intestines that might be harmful and cancerous now is expelled quicker. It is well-known that fiber can reduce the risk for colon cancer (and conversely, that a low-fiber diet is a risk factor for colon cancer), because fiber helps speed things along. I bet magnesium helps to reduce cancer in a similar way. Just be careful you don’t get too much of a good thing- as high amounts of magnesium can cause diarrhea. As far as using magnesium to treat pre-eclampsia and eclampsia, I once heard magnesium described as “nature’s calcium-channel blocker.” Many people say that it helps relax muscles as well.

Magnesium has been identified as effective in treating several conditions. Results of an extensive review of well-designed trials focusing on colorectal cancer should encourage practitioners to consider advising patients to take magnesium supplements and probiotics to promote better digestive health. This study is a step forward because colorectal cancer is so prevalent. It also points to the need for greater collaboration among researchers.

Colorectal cancer risk increases with a sedentary lifestyle and high-fat/low-fiber diet, obesity, etc in addition to family history. This picture fits the modern American lifestyle perfectly, and it is not surprise that colon cancer affects about 150,000 Americans annually. Although this type of cancer isn't as prevalent as some other cancers such as lung or breast cancer, this is still a plaguing disease that must be prevented. In addition to getting screened for colorectal cancer after the age of 50, incorporating more magnesium into our diets such as from buckwheat, oat bran, artichokes, almonds, pine nuts etc. would be essential. I have a family history of multiple types of cancers, so I would need to do some research on how to incorporate more magnesium into my diet. Thanks for uploading this study.

Colon cancer risk is something I talk about often with patients in my pharmacy, usually when they are picking up medications to prepare for colonoscopies. It is great to see such a large-scale patient population showing effectiveness of magnesium on decreasing colon cancer risk. I am happy to have another natural option to decrease this risk in addition to the usual probiotics and fiber. I also did not realize that magnesium was so helpful in the treatment of eclampsia and pre-eclampsia; this is not something I see often in my workplace, but great information to store away for a later day. Thanks!
