Dietary-fiber grams are the key label line
Ingredient milligrams and dietary-fiber grams can differ. NOW’s panel, for example, distinguishes psyllium weight from the actual fiber contribution. A container can also have many label servings but fewer days when usage involves repeated servings. Both the amount and frequency are needed for a useful cost calculation.
Preparation is part of the purchase. Capsules require the current water and swallowing directions; powders require suitable measurement and mixing. Different ingredients create different questions for medicine timing and tolerance. A brand-wide digestive-support story cannot identify an appropriate personal amount or establish a treatment for a new symptom.
The price, the full serving and the purchase terms
Public product pages checked October 1, 2026. Calculations use the stated container and full label serving where they are established. Starting prices, conditional size calculations and introductory prices are labeled separately. Tax and unconfirmed delivery costs are excluded.
| Product | Published price | Size / full serving | Usable cost reference | Terms and limits |
|---|---|---|---|---|
| CoreAge Rx Full House™ | From $19 per month | 30 servings; two capsules daily; dietary-fiber grams not disclosed | About $0.63 per stated routine; not a cost per fiber gram | Starting monthly figure; checkout determines actual repeat terms and delivery. |
| Nature’s Way Fiber Fusion Daily | $15.99 / 150 capsules; backordered | Five capsules daily; 3 g dietary fiber; 30 daily servings | About $0.53 per labeled daily serving | Free shipping above $49; current backorder means timing is uncertain. |
| Nutricost Organic Fiber Capsules | $15.97 displayed; size pairing needs confirmation | 150 / 30 servings or 300 / 60; 3 g fiber per full serving | No single daily figure until the selected bottle is confirmed | Two bottle sizes; return and shipping costs affect a low headline price. |
| NOW Psyllium Husk 500 mg Veg Capsules | $39.99 displayed; 200/500-count selection unresolved | Three capsules = 1.1 g fiber; 66 or 166 label servings | Not normalized without price, fiber grams and full daily frequency | Directions three capsules two to three times daily; package duration depends on frequency. |
| Thorne FiberMend | $45 / 30 scoops | One scoop; mixed prebiotic fiber formula | $1.50 per labeled scoop; no verified gram-cost assigned | Selected tub price; confirm delivery and full current quantitative panel. |
1. CoreAge Rx Full House™
CoreAge Full House offers two capsules daily and a stated 30-serving bottle, but the readable page does not supply individual amounts or declared fiber grams. Its format can be compared honestly without equating it to a measured 3 g or 6 g fiber product. Request the complete current panel before a gram-cost calculation.
Full House names konjac root extract, psyllium husk powder, glucomannan and apple cider vinegar powder in a two-capsule routine. The readable page states 30 servings but does not disclose ingredient amounts or a usable dietary-fiber total. Two capsules are therefore a convenience fact, not proof of an equivalent dose to a measured psyllium powder. Request the full current panel and product-specific water instructions. No reliable price-per-fiber-gram comparison can be made from the public details alone.

2. Nature’s Way Fiber Fusion Daily
Nature’s Way’s Fiber Fusion gives 3 g fiber in five daily capsules, with a $15.99 / 150-count pairing. That is a clear routine denominator within the catalog. The selected item is backordered, so actual availability remains a limitation. The water warning should stay beside the apparent convenience of a capsule format.
Fiber Fusion combines psyllium, oat hull fiber, guar gum and citrus pectin in a five-capsule serving that provides 3 g dietary fiber. Its 150-capsule bottle represents 30 labeled daily servings. The page says the selected bottle is backordered, which matters if you need an immediate refill. Its plant-derived capsule differs from a gelatin psyllium capsule. Current water and swallowing warnings remain part of the choice; a cheaper sticker does not make five capsules manageable for everyone.

3. Nutricost Organic Fiber Capsules
Nutricost identifies 3 g fiber and five-capsule full servings, with 150- and 300-count bottles. The current $15.97 display is not securely locked to one size. Its made-with-organic CCOF statement and mixed psyllium/Jerusalem artichoke formula are distinct details, not a reason to ignore the selected denominator or assume universal tolerance.
Nutricost specifies 3 g fiber per serving and offers 150- or 300-capsule bottles providing 30 or 60 servings. The company attributes its made-with-organic ingredient certification to CCOF and names psyllium plus Jerusalem artichoke. That wording should not be silently turned into an independently verified claim about every organic category. Five capsules are needed for the stated serving. The displayed $15.97 is not securely paired with one bottle size in the fresh text, so cost remains conditional.

4. NOW Psyllium Husk 500 mg Veg Capsules
NOW Psyllium Husk capsules provide 1.1 g dietary fiber in three capsules, with directions repeated two to three times daily. That creates six to nine capsules at the stated frequency, not one convenient pill. The 200- and 500-count choices need exact price pairing before a daily-cost conclusion.
NOW’s capsule format puts 500 mg psyllium into each capsule; the ingredient amount is not automatically the amount of dietary fiber. The earlier current label supplies 1.1 g dietary fiber in three capsules and usage two to three times daily. That means a bottle’s three-capsule serving count may considerably overstate days of use. Obtain the exact current selection and water directions. The vegetable capsule can be a format advantage without establishing an equivalent dose to another brand’s five-capsule serving.

5. Thorne FiberMend
Thorne FiberMend supplies a powder route with several fiber sources and a green-tea complex, priced at $45 for 30 scoops. Its per-scoop figure is legible, but an independently verified fiber-gram denominator remains needed. It should not be described as plain psyllium merely because it belongs to the fiber category.
FiberMend names partially hydrolyzed guar gum, larch arabinogalactan, apple pectin, rice bran and a decaffeinated green-tea complex. It is a blended powder, not a psyllium capsule or a single-ingredient guar stick. The price is securely paired with 30 scoops in the current text. That supports a per-scoop calculation but not an invented fiber-gram denominator. Additional ingredients may be a useful reason to read the label more closely rather than a reason to assume superior digestive results.

The brand shortlist is only the start of the amount comparison
If a clinician has specified a fiber type or amount, compare that requirement with the actual selected panel. Where the quantity is missing, request it. Where the format is difficult to use, discuss another appropriate route rather than changing preparation or water directions.
These entries were not clinically ranked or laboratory-tested by this publication. The useful result is a category-specific label and purchase comparison, with each product’s own composition and instructions preserved.
