Frequently Asked Questions
How do I pick between soluble, insoluble, and a blended fiber for my brand?
Start with the claim story. Soluble fibers (psyllium, inulin, acacia, glucomannan, beta-glucan, pectin, wheat dextrin, resistant starch) dissolve and gel or ferment, carrying satiety, glycemic, cardiovascular, and prebiotic narratives. Insoluble fibers (cellulose, plus the insoluble fraction of psyllium) add bulk for regularity and transit. Digestive SKUs run soluble-led blends (psyllium is roughly 70 percent soluble plus 30 percent insoluble, which is why it works for both regularity and LDL). Weight and GLP-1 SKUs lean viscous-soluble (glucomannan plus psyllium). Prebiotic SKUs lean fermentable-soluble (inulin, resistant starch).
Is dietary fiber a viable GLP-1 adjunct product? What goes in the formula?
Yes, and the channel is underbuilt. Roughly 25 million Americans are on GLP-1 medications (semaglutide, tirzepatide, liraglutide) and clinicians routinely recommend viscous soluble fiber for satiety and glycemic support alongside the protocol. A defensible stack: glucomannan 1-3 g plus psyllium 3-5 g in a single-serve stick pack 30 minutes pre-meal. Pair with our existing GLP-1 catalog (berberine 500-1000 mg, chromium picolinate 200-400 mcg, B-complex) for a full protocol line under one PO. Claim posture stays in structure-function (supports satiety, supports healthy blood sugar already within normal range) and never references the drug class on the label.
What is your sample policy and MOQ for a private label fiber SKU?
Samples: $150 base for the first SKU including UPS, $20 per additional SKU. Stock samples ship in roughly 7-14 business days from spec lock; custom samples add 1-2 weeks. Bulk MOQ: 500 units (stick packs, powder jars), 3,000 units (HPMC capsules), 1,500 units (pectin gummies), 2,000 units (RTD bottles). Terms: 50 percent deposit at quote acceptance, 50 percent before shipping. Most competitors publish none of these numbers.
Can you build a synbiotic SKU that combines fiber with a probiotic strain?
Yes, this is one of the highest-margin lanes we ship. Two house stacks: psyllium husk 5 g plus Bacillus coagulans GBI-30 6086 at 1-5 billion CFU (shelf-stable spore-former, survives stick-pack production, no cold chain); and inulin 3 g plus Lactobacillus acidophilus or L. rhamnosus GG at 1-10 billion CFU (delayed-release HPMC capsule, since these strains are moisture-sensitive). Other adds: L. reuteri DSM 17938, Bifidobacterium longum, and prebiotic-only stacks using FOS or GOS. CFU is guaranteed through expiry on the COA, not just at manufacture.
Is your psyllium husk gluten-free and certified for sensitive consumers?
Psyllium is naturally gluten-free (Plantago ovata is a seed husk, not a cereal grain). The risk vector is cross-contamination during handling. We source from suppliers with dedicated psyllium processing lines, third-party gluten testing on incoming raws under 20 ppm (FDA threshold), and segregated finished-goods QC. For celiac positioning we carry the spec at under 10 ppm with documented allergen-control SOPs. Our oat beta-glucan SKU requires a separate certified-GF oat sourcing program because oats are routinely contaminated in shared rotation with wheat and barley.
What is the FTC structure-function rule and what fiber claims can I legally put on a label?
FDA and FTC jointly police supplement labels under 21 USC 343(r)(6). Structure-function claims describe how an ingredient affects normal body structure or function and are the only claims usable without FDA pre-approval. Defensible fiber claims: supports healthy regularity, supports satiety, supports a balanced gut microbiome, supports digestive comfort, supports healthy blood sugar already within normal range, supports healthy cholesterol already within normal range. Off-limits: treats constipation, prevents diabetes, reduces risk of heart disease. Beta-glucan and psyllium have FDA-authorized NLEA claims under 21 CFR 101.81 with strict dose and wording rules we evaluate per SKU. Our regulatory team reviews every label and confirms Supplement Facts compliance per 21 CFR 101.36.
Which fiber source works best in a gummy, and why is the dose so low?
Gummies are taste-driven habit-stack products. Pectin gummies max at 1-3 g fiber per 2-gummy serving because higher loads either gel the gummy (psyllium turns the batter into a brick) or leave a chalky mouthfeel consumers reject. Inulin and acacia gum survive gummy production cleanly at 1-3 g and both ferment in the colon for a prebiotic claim. We will not put 5 g psyllium in a gummy because the dose math fails and the format damages the brand. Gummies belong in the daily-habit lane alongside a stick pack or capsule that carries the real clinical dose.
Do you publish certificates of analysis (COA) and fiber-content test results?
Yes. Every lot ships with a finished-goods COA confirming fiber content gravimetrically (AOAC 991.43, soluble and insoluble fractions broken out where warranted), heavy metals against California Prop 65 limits (stricter than FDA defaults), microbial limits (total plate count, yeast and mold, E. coli, Salmonella, S. aureus), allergens (gluten under 20 or under 10 ppm if specified), and CFU at expiry for synbiotic SKUs. Probiotic strain identity is confirmed via 16S rRNA sequencing. The documentation pack satisfies Whole Foods, Amazon Aplus, EU retailer, and big-box due diligence.

Buying Guide: Fiber Source + Format + Channel Fit
Fiber stopped being a niche digestive aid the day GLP-1 prescriptions crossed 25 million Americans. The category now spans three commercial shelves: digestive health (regularity, gut comfort, prebiotic), weight management (satiety, glycemic blunting, GLP-1 adjunct), and gut-axis stacks (synbiotic, skin-gut). Each shelf rewards a different source, format, and claim posture, and most contract manufacturers will sell you the same psyllium powder for all three. This page walks you through the decision in the order a founder actually faces it: shelf positioning, source (soluble vs insoluble, viscous vs fermentable), format (capsule, stick pack, gummy, RTD), synbiotic stack, MOQ and label. By the end you know what to ask for, what we charge for a sample ($150 base for the first SKU plus $20 per additional SKU, UPS shipping included), and what the 500-unit bulk MOQ commits you to.
Source is the first real choice. Soluble fiber dissolves and ferments (satiety, prebiotic, cholesterol); insoluble adds bulk (regularity, transit). Pick from: psyllium husk (Plantago ovata, soluble, 5-10 g, gold standard for regularity and LDL); inulin (chicory root, soluble fermentable, 3-5 g, prebiotic); acacia gum (Acacia senegal, soluble, 6 g, gentle low-gas); glucomannan (konjac root, soluble viscous, 1-3 g, satiety and GLP-1 adjunct workhorse); cellulose (insoluble, plain bulking); wheat dextrin (soluble, tasteless, Benefiber-style functional); oat beta-glucan (soluble, healthy cholesterol; sourced from certified gluten-free oat); apple or citrus pectin (soluble, gel-former, bile-acid binding); and type II resistant starch from high-amylose corn (prebiotic plus glucose-blunting). Most brands pick one hero source plus one supporting source; we will not blend more than three actives because dose math gets diluted fast.
Format follows shelf. HPMC capsules cap effective dose at roughly 600-900 mg per pill, which means a 5 g psyllium serving runs 6-9 capsules: niche only, fine for boutique gut-health brands, ruinous for adherence. Single-serve stick packs are the CRO winner across digestive, weight, and GLP-1 shelves because you can ship a full clinical dose (5-10 g) in one neutral or lightly flavored sachet that mixes into water, juice, or coffee; 500-unit MOQ, 10 g fill, three-side-seal foil laminate, optional flavor system. Pectin-based gummies work only as a habit-stack format at 1-3 g per serving (taste mandates low dose; we will not put 5 g psyllium in a gummy and call it functional). Ready-to-drink bottles are the premium-shelf play: higher per-unit cost, lower MOQ ceiling, best paired with a clean flavor system and a hydration-occasion narrative.
Synbiotic stacks (fiber plus probiotic) are where the highest-margin SKUs and most defensible claims live right now. Two we ship: psyllium husk 5 g plus Bacillus coagulans GBI-30 6086 at 1-5 billion CFU (shelf-stable spore-former, no cold chain, survives stick-pack production), positioned for regularity plus microbiome support; and inulin 3 g plus Lactobacillus acidophilus or L. rhamnosus GG at 1-10 billion CFU (delayed-release capsule or moisture-controlled stick), positioned for prebiotic plus microbiome diversity. The claim story holds because each ingredient does measurable work, doses are at clinical levels, and our regulatory team writes labels to FTC structure-function rules (supports healthy regularity, supports a balanced gut microbiome) and never wanders into disease territory. That discipline keeps brands off the FTC warning-letter list in a category where competitors regularly overclaim.
Our Manufacturing Process
From initial concept to finished product, every step is managed under one roof with dedicated quality oversight and transparent communication.
Positioning + Source Brief
Brief us on shelf (digestive, weight, GLP-1 adjunct, prebiotic, synbiotic) and target consumer. We map it to one hero fiber plus optional support, name the Latin source, set the per-serving dose to a clinical range, and confirm the claim posture (structure-function only, no NLEA disease claims). One-page formulation brief, no cost, no commitment.
Sample + COA Review
Samples ship at $150 base for the first SKU including UPS, $20 per additional SKU. Each sample arrives with a raw-material COA (heavy metals, microbial, allergen, identity) so your QA can sign off before commercial commit. Stock-formula samples ship in roughly 7-14 business days from approved spec; custom samples add 1-2 weeks.
Pilot or Full Production
Production in our Shenzhen cGMP facility under 21 CFR Part 111. Stock formula MOQ: 500 units stick pack or powder jar; 3,000 units capsule; 1,500 units gummy; 2,000 units RTD. Standard lead time 30-40 days from artwork lock plus 50% deposit clearance, balance due before shipping. Volume tiers step at 5K, 10K, 25K, 50K.
QC + Fulfillment
Every lot is third-party tested through ISO 17025 accredited labs for fiber content (gravimetric AOAC 991.43), heavy metals, microbial limits, allergens, and gluten where relevant. Finished goods ship UPS for samples, air freight (5-10 days) or sea freight (30-45 business days) for bulk to your warehouse, 3PL (ShipBob, ShipMonk, Easyship, Amazon FBA prep), or dropship partner.

No cold chain. Defensible 'supports a balanced gut microbiome plus healthy regularity' claim under FTC structure-function rules.
GLP-1 Adjunct Lane
Viscous soluble fibers (glucomannan 1-3 g plus psyllium 3-5 g) target the satiety mechanism semaglutide and tirzepatide patients are told to support. Stick-pack format, mixed into water 30 minutes pre-meal. Pairs with our existing GLP-1 catalog (berberine, chromium, B-complex) for a full protocol line. First-mover shelf, private label competition still thin.
Certified Gluten-Free Oat Beta-Glucan
Oat beta-glucan is the only fiber with broad consumer recognition for cardiovascular support, but oat cross-contamination is a real label risk. We source from certified GF-oat suppliers with documented segregated handling, third-party gluten testing per lot (under 10 ppm), and allergen-control paperwork built for Whole Foods and Amazon Aplus due diligence.
Multi-Format on One Line
Stick packs (5-10 g, neutral or flavored, foil laminate), HPMC capsules (low-dose niche), pectin gummies (1-3 g habit-stack, taste-driven), and RTD bottles (premium shelf). Same facility, same QC, same lead-time window. Launch a 3-SKU line (capsule daily, stick functional, gummy habit) under one PO.
