What is Fiber Smart?

Fiber Smart is a range of products from a company that goes by the name ReNew Life. The product is marketed as a digestive health product that promotes and supports the inbuilt digestion system in our bodies. Fiber Smart is available in both powder and pill form, and it all comes down to the tastes and preferences of a buyer.

According to ReNew Life, Fiber Smart is a probiotic formula with quite a number of probiotics contained in the formula christened 900 CFU probiotic formulas. However, Fiber Smart is primarily composed of Flax Fiber unlike many products marketed for similar use. For this reason, you will not find psyllium as you would find in the many alternatives.

The producers also claim that the products are free from GMOs, preservatives, gluten, wheat, salts, artificial flavors, animal products, and fillers. Basically, it is advertised as an all-natural ingredients product. Although Fiber Smart doesn’t contain added sugar, it has a mild, sweet taste that will blend well with meals.

Does Fiber Smart Really Work?

Fiber Smart is said to be an all-natural way of promoting digestive health. Most customers confuse it for a cure for ailments related to the digestive system, but the truth is the product is only useful when it comes to promoting digestive health. It doesn’t cure or repair any damage, caused by either physical injuries or health-related injuries, to the gut.

With this in mind, we can conclude that the list of ingredients suggests that this product is designed to promote digestive health. Most of the ingredients are popular within health circles and have been subject to many research studies.

Taking a lesser scientific approach to determining whether Fiber Smart really works, we asked customers who have bought and used this product for at least one complete dose. From the customer feedback, we can deduce that the product works. In fact, to put things figuratively, the product works for 9 out 10 people interviewed. All the same, the product is also rated highly by online retailers.

The product ( it is a range of them) can easily be purchased from the official website and other online and brick-and-mortar retailers. The official website doesn’t give free samples nor does it have a money-back guarantee. This might be quite a letdown, especially for customers who want to try out the product first.

Fiber Smart Ingredients – Are they Safe & Effective?

Flax seed

Flax is abundant in insoluble fiber, which encourages regular bowel motions. Flaxseed’s natural fiber absorbs water, softening the feces and allowing it to travel rapidly through the colon[1].

Slippery Elm bark

Recent research suggests that slippery elm bark can help alleviate the symptoms of inflammatory bowel illnesses such as Crohn’s disease, ulcerative colitis, and irritable bowel syndrome (IBS).[2]

Fennel Seed

Fennel seeds may also help reduce constipation by relaxing intestinal muscles. Soothing stomach and intestine muscles helps to reduce gassiness caused by constipation or acid reflux. The key component that gives fennel seeds their positive properties is anethole.

Marshmallow root

Marshmallow root has a history of use in treating various digestive problems, including constipation, heartburn, and intestinal colic. In 2011, researchers found that marshmallow blossom extract could help heal stomach ulcers in rats. It is traditionally known for its soothing effects on the digestive tract and for its potential health benefits. In our Viome Review article, we provide all the essential information about this ingredient to help readers make informed decisions.

Q: How Should You Take Fiber Smart?

A: If you are taking the capsule variant of Fiber Smart, you should take at least four capsules a day. You may want to spread them across two servings (two capsules in the morning and two capsules in the evening or late afternoon) or you may spread them over four servings (that is, with every meal and perhaps with the ten o’clock or 4 o’clock snack). If you are taking the powdered version, take two teaspoons twice a day. Make sure to take it with lots of liquid to avoid choking.

Q: Does fiber powder actually work?

A: Fiber has a variety of health benefits, including the ability to normalize digestive function and avoid constipation. Fiber is best obtained through food because supplements lack the vitamins, minerals, and other nutrients that fiber-rich meals do. However, fiber supplements can help you meet your daily fiber requirements.

Q: How long does it take for fiber supplements to work?

A: It works for 12 to 72 hours. It should result in a bowel movement between 12 to 72 hours. If your constipation lasts longer than seven days, see your doctor because it could be an indication of something more serious. Bulk-forming fibers, such as psyllium husk, may impair the effectiveness of medications.

Q: What are the directions of uses?

A: This product can be mixed with food and drinks or taken orally, whether in capsule or powder form. Typically, it is best taken in the morning with fruit juice (or whatever it is you take in the morning) and can follow up with an afternoon or evening dose with the evening meal.

Warning Before Use
