Choose the Quercetin Delivery Route
Before comparing prices, confirm what the stated milligrams represent: quercetin, a quercetin-containing complex, or the complete liposomal powder. These are different costing bases.
Depending on the quercetin form and processing history, aqueous dispersibility and particle characteristics can affect capsule fill, liquid appearance, and powder handling. Sophora japonica material may arrive as quercetin dihydrate or as an extract standardized to quercetin. The route determines the costing basis.
Route | What you are buying | Quote basis | Key checks |
|---|---|---|---|
| Conventional quercetin | Quercetin, quercetin dihydrate, or a standardized extract | Quercetin amount | Assay, source, contaminants |
| Phytosome | A defined quercetin–phospholipid complex | Complex weight + quercetin assay | Ingredient identity, assay, authorization to use the name |
| Liposomal liquid | A phospholipid suspension | Quercetin content + carrier system + liquid formulation | pH, preservation, dispersion, stability |
| Spray-dried liposomal powder | A dry delivery system | Quercetin content (%) + fill weight | Assay, moisture, redispersibility |
| Other colloidal system | A defined solubilization system | System-specific | Surfactant or carrier, process, stability in the chosen format |
A phytosome is not automatically interchangeable with a liposomal system simply because both use phospholipids.
Choose the Liposomal Quercetin Formula
Use when: Quercetin is the sole active, with the delivery system as the product differentiator.
Specify: Dihydrate, anhydrous, or Sophora japonica extract; the assay; the phospholipid source.
Trade-off: A phytosome raw material is costed on complex weight plus assay. This SKU is costed on quercetin in a liposomal carrier.
Default format: Capsule from spray-dried powder, or a bottled liquid when the brief is a suspension.
Use when: Vitamin C is the second active in a seasonal-wellness or antioxidant SKU.
Specify: Vitamin C form and milligrams, and whether it shares the liposomal system. For a liquid, set the pH target.
Trade-off: Ascorbic acid can lower pH and change phospholipid dispersion. A dry capsule or stick pack avoids that liquid-formulation constraint. Liposomal vitamin C
Default format: Capsule or stick pack.
Use when: The reference product is the three-ingredient seasonal-wellness SKU.
Specify: Zinc salt and elemental zinc as two numbers.
Trade-off: The zinc form can affect taste, moisture sensitivity, and dispersion. Separate delivery systems for each active are a different project from one blend.
Default format: Capsule or stick pack.
Use when: The reference label pairs quercetin with bromelain.
Specify: Bromelain activity in GDU or CDU, and whether the enzyme stays outside the liposomal carrier.
Trade-off: Heat and moisture can affect enzyme activity and should be considered in the blending and processing specification.
Default format: Hard capsule.
Use when: Fisetin is the second flavonoid in a healthy-aging capsule.
Specify: Fisetin source and assay, and whether the liposomal fraction contains quercetin, fisetin, or both.
Trade-off: A shared carrier can simplify one SKU but increases phospholipid load and capsule count. Fisetin
Default format: Hard capsule.
Use when: Spermidine is specified beside the two flavonoids.
Specify: Spermidine measurement basis before costing. Extract weight, free spermidine, and salt weight are separate numbers. Spermidine
Trade-off: The spermidine basis can materially affect capsule count and cost, particularly when the flavonoid load is high.
Default format: Hard capsule.
Use when: Both quercetin and resveratrol are specified in one polyphenol capsule.
Specify: Trans-resveratrol milligrams separately from polygonum-extract milligrams, and which active uses the phospholipid system.
Trade-off: If resveratrol is the primary active, its delivery system and assay requirements become part of the primary specification. Liposomal resveratrol
Default format: Hard capsule.
Liposomal Quercetin Format: Capsules, Liquids, Stick Packs or Powder
A spray-dried powder and a bottled suspension are quoted as separate projects.
Best for: Spray-dried liposomal powder.
Why this format: Dry filling avoids a liquid suspension and its preservation requirements.
Typical formula cards: Single-active. Quercetin + bromelain. Quercetin + fisetin. Quercetin + fisetin + spermidine. Quercetin + resveratrol.
What to lock: Shell, capsule size, fill weight, quercetin amount, desiccant, and bottle barrier.
Manufacturing note: Moisture and redispersibility are the process checks for the powder fill.
Best for: A bottled phospholipid suspension measured as a daily liquid.
Why this format: pH, preservation, and sediment behavior form part of the liquid release specification.
Typical formula cards: Single-active. Quercetin + vitamin C.
What to lock: Quercetin milligrams per milliliter, phospholipid source, pH, preservative system, flavor, and storage after opening.
Manufacturing note: Microbiology is included in liquid release.
Best for: Spray-dried powder used as a single-serve drink.
Why this format: The powder stays in a barrier pack. Taste and sediment are checked after mixing.
Typical formula cards: Quercetin + vitamin C. Quercetin + vitamin C + zinc.
What to lock: Grams per stick, quercetin milligrams per stick, flavor, and moisture barrier.
Manufacturing note: Reconstitution is a finished-product check, separate from the dry assay.
Best for: An ingredient buyer or a contract packer filling its own units.
Why this format: The quote is a kilogram price at a stated quercetin percentage.
Typical formula cards: Single-active liposomal quercetin.
What to lock: Quercetin percentage, carrier, moisture, redispersibility, foil or drum pack, and assay method.
Manufacturing note: Redispersibility and moisture are checked on the powder lot.
The following specification fields can materially change the quote.
1. Active basis
Quercetin dihydrate, anhydrous quercetin, or a Sophora japonica extract standardized to quercetin. Name the assay method, normally HPLC, and the result basis.
2. Phospholipid and carrier
Sunflower lecithin, soy lecithin, or a higher-phosphatidylcholine grade. The source sets the allergen position and the cost. A phosphatidylcholine target is locked when the label or the technical file states one. Liposomal supplement manufacturing
3. Delivery format
Capsule, bottled liquid, stick pack, or bulk powder.
4. Testing named in the specification
Particle size, polydispersity index, encapsulation efficiency, and zeta potential belong in the quote when the method and the batch result are part of the specification. A published target range is not a batch-specific result and should not be presented as one.
5. Pack
Quercetin and phospholipids can oxidize. Oxidation risk depends on the active form, carrier system, processing conditions, and packaging. HDPE with desiccant, foil stick, amber liquid bottle, and nitrogen-flushed bulk are selected with the format.
6. Quantity
Starting quantity, film or bottle, and testing scope.
Examples below are commercial label observations, not recommended intakes or KS formulas. Verify the current label before using a product as a costing reference.
Panel | What the serving is counting |
|---|---|
| Conventional quercetin capsule | Often 250–500 mg quercetin or quercetin dihydrate. Confirm the form. |
| Phytosome capsule | A common commercial format uses 250 mg of the phytosome complex. The quercetin contribution depends on the documented HPLC assay of that complex. |
| Liposomal liquid | One bottled product lists 166.6 mg quercetin dihydrate and vitamin E per 5 mL, in a sunflower-phospholipid suspension. |
| Liposomal healthy-aging capsule | One product lists 77 mg quercetin, 35 mg fisetin, and 3 mg spermidine trihydrochloride in the same serving. |
| Bulk liposomal powder | Quercetin milligrams equal the stated powder percentage times the fill weight. |
A raw-material CoA supports incoming release. Finished-product release follows the agreed specification. The two documents answer different questions.
The project file can include:
- Raw-material CoA for the quercetin and the phospholipid
- Finished-product CoA
- Product specification
- TDS and SDS
- Allergen statement
- Non-GMO statement where that statement applies
- Stability data when the project has it
- Third-party testing when the specification requires it
The following are planning figures, not guaranteed minimums. A bottled liquid is quoted after the suspension, bottle, and preservation system are confirmed.
| Format | Typical starting quantity |
|---|---|
| Capsules | About 3,000–5,000 finished units |
| Stick packs | 30,000 sticks |
| Bulk liposomal powder | 300 kg on the powder program; the liposomal grade is confirmed at quote |
| Bottled liquid | Quoted after formula, pack, and preservation are confirmed |
| Stage | Typical lead time | Starts after |
|---|---|---|
| Sample | 7–15 days | Approved specification |
| Commercial production | Often 30–45 days | Formula, artwork, packaging, testing scope, and production schedule approved |
Project Work Path:
- Brief. Send a concept, a reference label, or a formula.
- Route. Confirm conventional quercetin, phytosome, liposomal liquid, or spray-dried powder.
- Specification. Confirm identity, assay basis, dose, carrier, format, market, and pack.
- Sample. Produce the sample after that specification is approved.
- Production quote. Receive the price, MOQ, and lead time for the approved specification.
- Production. Manufacture, pack, and release the agreed batch documents.
What to Include in the First Inquiry
A reference label is enough to start. We separate the active amount, carrier or complex weight, format, and remaining specification fields before pricing.
- Product concept, formula, or reference label.
- Destination market.
- Format: capsule, liquid, stick pack, or bulk powder.
- Quercetin form and the costing basis.
- Other actives, with the measurement basis for each.
- Expected quantity and pack.
- Target cost range, if there is one.

If You Are Comparing Suppliers
Compare suppliers on the same basis: quercetin amount, assay basis, carrier system, phosphatidylcholine content where specified, finished-product testing, pack, starting quantity, and lead time. Compare like with like: a price based on complex weight is not directly comparable with a price based on quercetin content.
