Metamucil Fiber is a brand-name over-the-counter psyllium fiber supplement. It is marketed as “3-in-1 Fiber” and “4-in-1 Fiber.” The difference between the two products is the amount of fiber per serving: 3-in-1 Fiber contains 3 grams of psyllium and 4-in-1 Fiber contains 6 grams. With the larger amount of psyllium, 4-in-1 Fiber is marketed as an appetite control supplement in addition to the health benefits claimed for the 3-in-1 Fiber.
The fiber in Metamucil Fiber, psyllium, is a soluble, gel-forming fiber that can relieve constipation and promote bowel regularity. Used daily it can reduce cholesterol, blood sugar levels, and blood pressure. For appetite control and weight loss, psyllium, when taken before a meal, can provide a “full” feeling earlier in the meal so that less food is consumed at the meal.
Metamucil Fiber is taken as a tablet or powder one or more times a day.
Metamucil Fiber has few and minimal side effects including gas, bloating, and diarrhea. Metamucil Fiber should always be taken with an adequate amount of water or it might cause choking or bowel obstructions.
Metamucil Fiber is marketed as reducing blood sugar, which is one of the effects of psyllium, but Metamucil Fiber itself contains sugars, so it should be used with caution by people with insulin insensitivity or diabetes.
Psyllium allergies are rare but they may be severe, including anaphylaxis, a dangerous drop in blood pressure. If accidentally inhaled, which is possible in its powdered form, psyllium may cause asthma.
