If you’ve ever had problems going #2 💩, chances are you’ve been told to up your fiber intake. But what is fiber, and where do we get it from?

Fiber is an indigestible carbohydrate, aka a food your body can’t naturally absorb. Instead, fiber must pass through your stomach, small intestine, and colon, which is why it helps your bowel movements. But wait, there’s more!

There are two types of fibers: Soluble and insoluble. Soluble fiber dissolves in water — in that way, it becomes more like a gel that can sweep your intestines clean as it moves through your digestive system. We often find soluble fiber in foods like oats, peas, legumes, fruits, and psyllium. Insoluble fibre, however, doesn’t dissolve — so it moves everything in your digestive system along and increases stool bulk (which is ideal for those with constipation). Insoluble fiber is found in whole-wheat products, nuts, vegetables, and potatoes. If you consume a combination of the above, a high-fiber diet will help enable regular bowel movements, lower cholesterol and blood sugar levels, and reduce the risk of cardiovascular disease.

“If you’re lacking on the fiber front and can’t find it in your day-to-day diet due to dietary restrictions, lifestyle, or otherwise, a fiber supplement could help.”

According to the Mayo Clinic, women need between 21 and 25 grams of fiber a day. Pregnant people could increase their fiber intake for additional health benefits as well, up to 30 grams a day. If you take too much fiber too soon, you could experience negative effects like bloating, gas, or constipation. But if you’re lacking on the fiber front and can’t find it in your day-to-day diet due to dietary restrictions, lifestyle, or otherwise, a fiber supplement could help.

We’ve rounded up nine of the fiber supplements we recommend most for women. These fiber supplements offer 5–7 grams of fiber per serving (or about 20-30% of the recommended daily amount). It’s a good boost to help regulate your body’s digestive and gut health!

As always, though, we recommend speaking with your physician or nutritionist to see if a fiber supplement is right for you.

Our criteria:

Four different fiber supplements for women in various packaging, displayed on a cream background with circular accents.

We’ve researched and personally tried the best brands in the wellness space and have found the following supplements to be the most reliable and generally tolerated of the bunch. We update this list regularly with our emerging favorites that meet the following criteria.

HIGH-QUALITY INGREDIENTS | The supplements below use natural or organic ingredients that have been checked (in some cases, triple-checked) for quality and efficacy. Ingredients mimic natural sources of fiber we mentioned above, like organic fruits and veggies, beans, oats or bran, etc. None of the formulas includes fillers.
TRUSTED BRANDS | The seven brands below are highly reputable, leverage clinical research to inform their practices, and test formulas via third parties for efficacy and safety.
TOLERABILITY | These supplements include a generous yet gentle amount of fiber per serving — none should be more than 30% of your daily needs, which reduces the likelihood of negative side effects. The formulas are also made for several dietary lifestyles, so we’ve noted which options are gluten-, GMO-, or sugar-free and/or suitable for vegans and vegetarians.

1. Thorne

Best For | Prebiotic fiber powder
Fiber Content | 7 grams per scoop (11g of powder per scoop)
Ingredients | Green tea phytosome, guar gum, larch extract, apple pectin, rice bran

Balance your belly’s gut health with Thorne’s FiberMend. This plant-based powder combines decaffeinated green tea, larch tree extract, apple pectic, and rice bran into a gentle formula — one that will simultaneously help digestive function, promote regularity, and balance healthy blood sugar levels. Since it’s odorless and flavorless, you can simply add one scoop a day into your preferred beverage. The fiber in this prebiotic formula is soluble, so you shouldn’t experience any bloating or gas like you might with other brands. See why many doctors, athletes, and even the Mayo Clinic recommend Thorne.
