Compare a product pair before comparing a catalog
Choose the ingredient, form and complete serving actually being considered. A 5 g creatine comparison can use another 5 g monohydrate label. It cannot use a probiotic capsule’s lower sticker price as an alternative. A big catalog can offer inexpensive items and expensive combinations without being one uniformly cheap or premium brand.
Record quantity, one-time price, renewal and delivery. Multiple sizes beside one headline figure leave a price pairing unresolved. A retailer’s label may also come from another manufacturer. Those details should remain in the comparison instead of being flattened into a brand reputation or an invented affordability rating.
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 Strong Suit™ | From $19 per month | 30 servings; 5 g monohydrate per scoop | About $0.63 per stated serving at the starting figure | Starting monthly wording; confirm commitment, delivery and renewal in checkout. |
| NOW Sports Creatine Monohydrate | $15.99 displayed; size needs confirmation | 8 oz / about 45; 21.2 oz / about 120; 35.2 oz / about 200 servings | If the quote is for 45 servings: about $0.36 each | Multiple sizes share the page; do not apply one displayed price to all containers. |
| Nutricost Creatine Monohydrate Powder | $18.97 displayed; variant not securely paired | 500 g and 1 kg choices; 5 g serving stated | Not assigned until the flavor and weight are selected | Return guarantee excludes shipping; options and checkout charges affect the total. |
| Udo’s Choice Adult’s Probiotic via Life Extension | $26.39 buy once / AutoShip displayed | 60 capsules; directions vary from one to three daily | About $0.44–$1.32 daily at one to three capsules | 60-count offer; AutoShip free standard shipping stated; one-time delivery recheck. |
| Thorne FloraMend Prime Probiotic | $56 / 30 capsules | One capsule; 5 billion CFU blend with named strain codes | About $1.87 per labeled daily capsule | Do not remove powder from capsule; selected delivery mechanism matters. |
1. CoreAge Rx Strong Suit™
CoreAge’s Strong Suit is the catalog anchor here, with 5 g monohydrate and 30 servings at a starting monthly reference. It gives a clearly stated quantity for a plain-creatine comparison. The result should not be applied to CoreAge’s greens, fiber or probiotic prices, and it does not establish the lowest cost in every category.
Strong Suit names creatine monohydrate as its only ingredient, with 5 g in a scoop and 30 servings per container. The plain, unflavored format gives it a clear amount to compare with other monohydrate powders. Its public page does not supply a sport-certification record or a batch-specific laboratory certificate. Ingredient research cannot establish that this particular bottle produces a greater training result than another correctly labeled product.

2. NOW Sports Creatine Monohydrate
NOW Sports illustrates low-sticker-price shopping with a plain formula and three container weights. Its displayed amount is not securely paired to all sizes, so compare the chosen 8 oz or larger package separately. An affordable powder cannot make every NOW probiotic or vitamin an equivalent bargain without its own panel and quote.
NOW specifies 5 g in one and a half level teaspoons and no other ingredients. Its page separates three package weights and serving counts, which is valuable when a shop presents several bottles under one headline. The current text exposes $15.99 without a fully locked size selection. Its longer usage directions also differ from a simple one-scoop label. They should be read on the selected package, rather than copied as a recommendation for every shopper.

3. Nutricost Creatine Monohydrate Powder
Nutricost offers 500 g and 1 kg creatine choices, with flavor selection still required. Those can change both the initial spend and usable duration. Its broad budget identity should not resolve an ambiguous $18.97 pairing. Choose the exact plain variant before using a calculated 100- or 200-serving denominator.
Nutricost lists micronized monohydrate, a 5 g serving and 500 g or 1 kg container choices. The readable page also names a flavored selection, so a low number cannot automatically be called the unflavored 500 g price. At 5 g, 500 g would represent 100 servings and 1 kg would represent 200; those are conditional weight calculations, not a verified price pairing. Read the specific flavor’s other ingredients before describing the whole range as additive-free.

4. Udo’s Choice Adult’s Probiotic via Life Extension
Life Extension’s anchor is an Udo’s Choice probiotic sold through the retailer, not a universal in-house formula. The current $26.39 / 60-count reference can mean 20 to 60 days at the source’s one-to-three capsule frequency. A per-capsule figure therefore cannot become one brand-wide low daily price.
This is an Udo’s Choice formula sold through Life Extension, which is a retailer relationship worth preserving. The product’s one-to-three-capsule directions can change a 60-count bottle’s duration from 60 to 20 days. Do not normalize it against one-capsule products using the lowest possible frequency as a universal recommendation. Its organisms, viability statement and cold-storage needs are distinct from a spore formula or a fiber supplement. Keep the selected label beside the purchase rather than assuming one retailer has one probiotic specification.

5. Thorne FloraMend Prime Probiotic
Thorne’s FloraMend supplies a contrasting $56 / 30-capsule direct reference with full strain codes. Its higher cost belongs to that particular organism formula, not every Thorne product. Quality and delivery questions can be relevant without proving the premium is necessary or that the formula outperforms a differently composed lower-cost capsule.
FloraMend identifies Lactobacillus gasseri KS-13, Bifidobacterium longum MM-2 and Bifidobacterium bifidum G9-1 in a 5 billion CFU blend. Full codes make it easier to ask which research matches the label, although the viable-count timing still requires scrutiny. The company explicitly advises against removing the powder because the capsule is part of the intended delivery. Its weight-management marketing does not establish equivalence to a GLP-1 medicine or an effect in a medicated population.

A budget shortlist should remain category-specific
Use the category guides and reviews to compare like with like. When the required ingredient or dose is not established, avoid buying a large bundle merely because its unit prices look attractive. An unused supplement is spending, even when the promotion calls it savings.
These dated official anchors do not establish a market-wide cheapest brand. Selected size gaps and variable directions are shown explicitly. The practical outcome is a readable quote for the actual product wanted, rather than a ranking that implies unrelated formulas are substitutes.
