The best colon cleanse

What to know before you buy a colon cleanse system

What is a colon cleanse?

The large intestine and the colon are the digestive tract area that absorbs water and turns your digested food into a stool. Some individuals believe that toxins gather in the colon and then absorb into your body. These individuals believe this can cause fatigue, headaches, decreased energy and weight gain. A colon cleanse flushes the colon, removing elements that may be harmful to your body.

Are there any side effects associated with a colon cleanse?

A colon cleanse should only be performed with your doctor’s knowledge and approval. While most of the side effects are related to discomforts such as gas, cramping, constipation, diarrhea and nausea, some of them can be more dangerous. It is possible to deplete your beneficial gut flora during a colon cleanse, so it is important to include probiotics to help maintain or rebuild that flora. Even more serious, a colon cleanse may cause dehydration, leading to excessive thirst, tiredness, dizziness, confusion or an electrolyte imbalance.

What to look for in a quality colon cleanse system

Oral colon cleanse systems include a series of tablets or capsules that deliver a range of specific active ingredients to help the body initiate and achieve a colon cleanse. Because there can be a wide range of ingredients, it is crucial to understand what is included in your colon cleanse system to know how those ingredients may affect you. 

Insoluble fiber

Insoluble fiber does not break down during its journey through the digestive tract. Instead, it absorbs water and adds bulk, acting, in some ways, like a brush as it moves through your system.

Soluble fiber

Soluble fiber breaks down into a gel-like substance which is vital for reducing blood cholesterol and sugar. It also helps a stool pass smoothly through the intestines.


Laxatives work in a variety of ways. Some may irritate nerves to stimulate activity in the large intestine, while others may add bulk to the stool, increasing the frequency of bowel movements. Still, other laxatives may function as softeners or lubricators. If there is a laxative in a colon cleanse system, make sure you understand which type it is so you know what to expect. 

Digestive aids

Since there will be increased digestive tract activity, this can result in excessive gas and cramping. The best colon cleanse systems have additives that will reduce these uncomfortable symptoms.

Probiotics, vitamins and minerals

A colon cleanse can remove good gut bacteria and essential vitamins and minerals from your body. The best colon cleanse systems include probiotics, vitamins and minerals to keep you healthy and adequately nourished during your cleanse.

How much you should expect to spend on a colon cleanse system

At the low end of the price scale, you can get a simple colon cleanse system for less than $15. However, if you are interested in a more complex system that contains multiple capsules and powders, you may be spending upward of $100. The average price range is roughly $15-$40.
