What Does a Daily Fiber Packet Really Cost?
What Does a Daily Fiber Packet Really Cost? Serving Size and Monthly Budget
A box of WonderBiotics Daily Fiber Mix holds 30 sachets and costs $29.90 one time, or as low as $22.36 a box through Subscribe & Save. What you pay each month depends on how many sachets you take a day, since the label allows 1 to 3.
How Many Sachets Are in One Box, and What Does Each One Cost?
Each box contains 30 sachets, and each sachet is a single 6 g serving of the fiber blend1. At the one-time price of $29.90 per box:
$29.90 ÷ 30 sachets = $0.997 per sachet (a hair under $1.00, and $1.00 once rounded to the nearest cent).
WonderBiotics also sells larger one-time bundles: a 3-box bundle (90 sachets) for $88.90, and a 6-box bundle (180 sachets) for $178.901. The same division on those:
- $88.90 ÷ 90 sachets = $0.988, about $0.99 per sachet
- $178.90 ÷ 180 sachets = $0.994, about $0.99 per sachet
Buying a bigger one-time bundle barely moves the per-sachet price. The 6-box bundle costs $0.50 less than buying six single boxes would ($178.90 vs. $179.40), a real but small discount. The bigger savings come from subscribing, not from bundle size.
Subscribe & Save: Three Tiers, and What Their Percentages Are Actually Measured Against
Daily Fiber Mix has three Subscribe & Save price points, each tied to a shipment frequency and savings percentage1:
| Shipment frequency | Price shown | Savings WonderBiotics displays | Price per sachet |
|---|---|---|---|
| Every month | $25.42/mo | 15% | $0.847, rounds to $0.85 |
| Every 3 months | $23.70/mo | 20% | $0.790 |
| Every 6 months | $22.36/mo | 25% | $0.745, rounds to $0.75 |
For the monthly tier, 15% off the single-box price of $29.90 is $29.90 − $4.485 = $25.415, approximately matching the displayed $25.42. For the every-3-months tier, $23.70/mo × 3 = $71.10 as a monthly-equivalent total; compared with the $88.90 three-box one-time bundle, that's a $17.80 difference, or 20.02%, approximately matching the displayed 20% but only when measured against the $88.90 three-box bundle rather than against three separate $29.90 single boxes. The every-6-months tier follows the same pattern: $22.36/mo × 6 = $134.16 monthly-equivalent total, a $44.74 difference from the $178.90 six-box bundle, or approximately 25.01%.
That pattern suggests the every-3-months and every-6-months tiers ship the matching 3-box or 6-box quantity at that frequency, discounted off the one-time bundle price for that same quantity. The checkout flow should confirm shipment size directly. Until then, read this as a calculation from the displayed prices, not as a separate quoted shipment promise.
How Much Will You Spend a Month at 1, 2, or 3 Sachets a Day?
The label's directions are "take 1 to 3 sachets daily"1. Using a 30-day month, the table below works from the one-time single-box price and each Subscribe & Save tier's displayed monthly price:
| Sachets per day | Sachets needed per month | One-time | Subscribe, monthly | Subscribe, every 3 mo | Subscribe, every 6 mo |
|---|---|---|---|---|---|
| 1 | 30 | $29.90 | $25.42 | $23.70 | $22.36 |
| 2 | 60 | $59.80 | $50.84 | $47.40 | $44.72 |
| 3 | 90 | $89.70* | $76.26 | $71.10 | $67.08 |
*If you're buying one time at 3 sachets a day, 90 sachets is also exactly what the pre-bundled 3-box option contains. Buying that bundle for $88.90 instead of three separate single boxes ($89.70) saves $0.80 a month at that dose.
Each subscribe column is WonderBiotics' displayed per-month price multiplied by how many boxes' worth you need that month (for example, $25.42 × 2 = $50.84, or $23.70 × 3 = $71.10). If you land on two or three sachets a day, check whether the subscription quantity at checkout matches that higher monthly need or whether you need a separate top-up.
Why the Label's "1 to 3 Sachets Daily" Range Changes Your Number So Much
Fiber tolerance is individual. Some people feel their best digestion at one sachet a day; others build up to two or three sachets as their gut adjusts to more fiber over a few weeks. That range also matters if you're trying to close the gap between what you normally eat and general fiber intake guidance: the National Academies' Adequate Intake for fiber is 25 g/day for non-pregnant, non-lactating women ages 19-50, and 21 g/day for women 51 and older.2 A single 6 g sachet is a partial contribution toward that number, not the whole thing on its own.
Starting at one sachet a day is also the simplest way to keep your monthly number at the low end of the ranges above while you find your dose. If one sachet is doing the job, there's no reason to take more; if you and your dietitian decide two or three sachets fits your routine better, the tables above show what that costs before you commit to it.
Keeping Your WonderBiotics Daily Fiber Mix Budget Predictable
We built Daily Fiber Mix as a single 6 g sachet, measured out for you rather than left to a scoop. Every standard box holds 30 of these 6 g sachets; the price differences across the tiers above come from how many boxes you buy and how often.
If you already know you'll want fiber daily for more than a month or two, subscribing at the every-3-month or every-6-month frequency locks in $23.70 or $22.36 a box instead of the $29.90 one-time rate. If you're not sure yet whether daily fiber will fit your routine, WonderBiotics also sells a 7-sachet trial pack1, a lower-commitment way to find your dose before you build a monthly budget around it.
