Compare a complete purchase, not a headline
Use the exact variant and quantity selected for the order. Record the amount due today, delivery and any separate service fee before estimating continuing spending. Where an offer is a monthly equivalent on a longer term, record the full advance charge and the ordinary renewal. Do not normalize unlike products to a guessed month of use. If the source does not identify a denominator, preserve that uncertainty instead of filling it with an assumption.
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™
Confirm the complete selected invoice, quantity and ordinary renewal. A figure without that supply information should remain a starting reference, rather than a price for every version of the product.
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
Compare the quoted order with the same purchase period, and ask which extra charge is excluded. Do not multiply an introductory rate into a year of ordinary spending.
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
A larger quantity can lower an arithmetic unit cost while requiring more money now. Obtain the exact container or prescribed supply before deciding whether the order fits the budget.
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
The purchasing model matters as much as the label price. Identify any separate service fee, prepaid term and shipping condition, and compare the actual order rather than a broad brand offer.
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
Keep this alternative’s complete payment beside its real supply. Missing quantity or an unresolved renewal prevents a reliable like-for-like value conclusion, even when the headline looks inexpensive.
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.

Make the order fit the actual routine
Put the answers beside the actual label and selected order. Keep any unresolved formula, supply or renewal question visible before deciding whether this option fits the routine.
