High fiber diets are essential for healthy digestion. Varieties of beans such as split peas, black beans, legumes, lima beans, cereals, artichokes, and fruits such as raspberries, bananas, mangoes, etc. are some of the high fiber sources that are available.

The Dosage of Fiber Supplements

The majority of the fiber supplements are available in powder form. They are convenient to use as it can be mixed with water or any other liquid of your choice. Fiber supplements are also available as capsules, gummies, caplets which are portable and easier to consume.

Generally, the dosage can vary depending on factors such as age, medical conditions for which it is consumed, and the health of the user. Usually, it is preferred to start with a low dose and gradually increase the dosage daily. The maximum fiber that an individual can consume is 25 grams for women and 38 grams for men.

If you want to take a supplement to get relief from conditions such as IBS (irritable bowel syndrome) and IBD (inflammatory bowel disease), consult a doctor before starting a supplement. Fiber supplements are best taken with meals for efficacy.

Generally, the recommended dosage is split across a day and for good reason. This has a two-fold benefit. First, a divided dosage gives your body ample time to process a supplement and second, taking it with meals ensures you don’t miss out on a dose.

Fiber supplements contain soluble fibers, which are more effective with water. So, drink at least a glass of water while taking the supplement. Also. taking it right before a meal might help with a faster feeling of fullness that helps prevent overeating. 

The Side Effects of Fiber Supplements

The key components of most of the fiber supplements are psyllium and methylcellulose.  The side effects of ingesting these ingredients are very minimal though scientific evidence suggests that sensitivity to psyllium dust can induce side effects in certain people. (1)

Though fiber supplements can offer immense benefits, fiber supplements can cause bloating, gas or even loose stools at least for the initial period of intake. Taking the supplements in smaller doses with meals can help alleviate this issue.  Drinking less water too can aggravate bloating as water is required to help push the fiber through the digestive tract. (2)

If you have any previous medical history of intestine related issues, like Crohn’s disease consult a doctor before taking any fiber supplements. Check with your doctor about taking fiber supplements especially if you have any medical conditions or are under prescribed medications as fiber supplements can reduce the absorption of certain medications. (3)

The Final Note

Adding fiber-rich food items like whole grains, cereals, fruits, vegetables, and legumes into your daily diet can be an excellent way to consume the advised amount of fiber. But a majority of individuals find it difficult to obtain an adequate amount of fiber from food sources alone. In such cases, fiber supplements come in handy to make up for the deficit in fiber from diet.

A sudden increase in fiber intake can result in temporary gastrointestinal troubles that subside after a few days once the body gets used to the extra fiber. Taking smaller doses and increasing the fiber intake gradually as long as there are no major gut issues, will prove to be beneficial for maintaining good gut and overall health.
