What You Might Not Know About Fiber Supplements Could Hurt You

Eating a high fiber diet has many advantages, including keeping your gut healthy and happy, boosting heart health, gut health, and improving weight loss efforts. The majority of Americans fail to meet the recommended daily amounts of fiber and turn to supplements to fill in the gap. However, most consumers are unaware that there are some potential health dangers associated with the consumption of these supplements. Let’s take a closer look at these.

The dietary guidelines for Americans recommend adequate daily fiber intake for adult men is 33.6 grams per day and 38 grams for women. Sadly, most people don’t even come close to this goal. The average fiber intake in America is 17 grams, and only 5 percent of people meet the adequate daily intake

Fiber supplements are lacking in essentials

One of the main drawbacks of any supplement is that it lacks vitamins, minerals, and protective antioxidants that you get when you eat high-fiber foods such as vegetables, fruits, whole grains, beans, and lentils.

Fiber supplements may interfere with the absorption of certain minerals and drugs

Fiber supplements may reduce the absorption of certain, necessary minerals and interfere with some prescription drugs, including antidepressants, cholesterol, diabetes, thyroid, and heart medications, to name a few. Be sure to speak with your physician if you are considering a fiber supplement and currently take prescription medication.

Fiber supplements may cause constipation and even bowel obstruction

According to the Cancer Treatment Centers of America, too much fiber supplement can turn what most people think is a remedy for constipation, into something very painful. If you don’t drink adequate water with a fiber supplement, the extra fiber can get stuck in the intestines causing constipation or even bowel obstruction.

Fiber supplement warning

If you are taking a fiber supplement, be sure that it has a high level of water-soluble fiber, such as psyllium. Be leary of products that contain sugar or artificial ingredients. Always, always, add fiber into your diet slowly to avoid painful gas and bloating. Talk to your physician about how much fiber is best for you and recommendations on how to meet your personal fiber goals that vary with age and gender.
