A shopper picks up a bottle of fiber gummies, reads 5 grams per serving on the front, and puts it in the cart. The same shopper walks past the powder that delivers the same 5 grams for a third of the price. The gummies are not a bad product. They are a bad deal dressed as a convenient one, and the label explains exactly why.

The dose is the first thing to check. Metamucil gummies deliver 5 grams per three gummies, from inulin and corn fiber, with no psyllium in the formula. Konsyl powder delivers 5 grams per teaspoon, 3 grams of it soluble. Garden of Life delivers 9 grams per 27-gram scoop. Capsules deliver about 1.1 grams per three capsules. Labeled doses across the category range from 0.5 to 9 grams, and adults need 25 to 38 grams a day from food and supplements combined.

## What the gummy dose actually buys

Five grams is a meaningful dose for one serving, but it is a small share of the daily target. A person getting 15 grams from food still needs 10 to 23 grams more, which is two to five servings of gummies a day. At three gummies per serving, that is six to fifteen gummies, and the bottle empties in a week. The powder that delivers the same 5 grams per teaspoon lasts months at the same daily dose.

The fiber type matters as much as the dose. Psyllium is the best-supported fiber for constipation and IBS-C, with the strongest trial record in the category. The gummies use inulin and corn fiber instead, because psyllium does not set into a gummy. Inulin ferments in the gut, which means gas and bloating for the people most likely to buy a fiber gummy. The product solves the taste problem and creates a tolerance problem.

## The cost per gram, done honestly

The comparison that matters is cost per gram of fiber, not cost per bottle. A bottle of gummies that costs 15 dollars for 30 servings of 5 grams delivers 150 grams of fiber, or 10 cents a gram. A canister of psyllium powder that costs 12 dollars for 100 servings of 5 grams delivers 500 grams, or about 2 cents a gram. The gummies cost five times as much for the same fiber, before the sugar and the flavoring are counted.

The gummies also carry what the powder does not: added sugar or sugar alcohols, flavoring, and the calories that come with them. Three gummies add roughly 15 to 25 calories a serving, which is trivial on its own and real at five servings a day. A person taking gummies for regularity is adding sugar to solve a problem that a spoonful of powder solves without it.

## When gummies are the right call anyway

There is a real case for gummies, and it is not the dose. It is adherence. A person who will not mix powder into water, who travels, or who needs a fiber source that fits in a desk drawer will take the gummies and skip the powder. A supplement that gets taken beats a supplement that sits in the cupboard, and the trial record is clear that the fiber has to be taken daily to work.

The honest way to buy them is to treat the dose as a supplement to food, not a replacement for it. Get the bulk of the 25 to 38 grams from food, use the gummies for the gap, and check the label for the fiber type before the price. If the label says inulin and the buyer is gassy, the powder was the right call all along.

## Frequently asked questions

### How much fiber is in a serving of fiber gummies?

Usually 5 grams per three gummies, from inulin and corn fiber. Labeled doses across fiber supplements range from 0.5 to 9 grams per serving, and adults need 25 to 38 grams a day from food and supplements combined.

### Are fiber gummies as effective as psyllium powder?

Not for constipation. Psyllium has the strongest trial record in the category, and gummies do not contain psyllium because it does not set into a gummy. The inulin in most gummies ferments in the gut, which can cause gas and bloating.

### Why do fiber gummies cost more than powder?

Cost per gram is the honest comparison. A typical gummy bottle delivers about 150 grams of fiber for 15 dollars, or 10 cents a gram. A psyllium canister delivers about 500 grams for 12 dollars, or 2 cents a gram. The gummies cost about five times as much for the same fiber.

### When are fiber gummies the right choice?

When adherence is the problem. A person who will not mix powder into water, who travels, or who needs a desk-drawer source will take the gummies and skip the powder. Treat the dose as a top-up on food fiber, not a replacement for it.
