Available Specifications
Grades, sources, and marker rules should be locked for your final projects.
RFQ tip: Same “40%” from different suppliers is not automatically interchangeable if the source, marker ratio, or assay basis differ.

20%: Cost-efficient blends,tablets&powders, Higher fill weight at same active target
40%: Workhorse private label/mainstream capsules, Most common starting grade
60%: Concentrated programs, Better fill economy vs 20%/40%
80%: High-concentration fills, Tighter weighing & blend control
90%: Specialty / assay-locked premium, Confirm assay basis at RFQ

Fermented soy isoflavones: Project-scoped specialty briefs
Isolated genistein/daidzein (≥98%): Specialty high-purity programs
Appearance: Light yellow to brown free-flowing powder
Active marker: Total isoflavones (HPLC); genistein/daidzein / glycitein as locked
Testing method: HPLC (state calculation basis)
Extraction/concentration: Project-locked pathway

Dietary attributes: Vegan pathway · Non-GMO · Organic (project-scoped)
Raw Material Quality Standards
Release Logic
Check | Why it matters |
|---|---|
| Identity testing | Confirms material matches the locked soy isoflavone definition |
| HPLC assay | Total isoflavones (and markers if locked) inside spec |
| Heavy metals | Botanical OEM baseline safety control |
| Pesticides | As required by grade / market / customer brief |
| Residual solvents | As required by extraction pathway |
| Microbiology | Standard botanical release item |
| GMO status | Conventional vs Non-GMO pathway must match claims |
| Allergen statements | Retailer/import onboarding |
Documentation Pack (Typical)
- Specification Sheet / TDS
- Certificate of Analysis (COA) by lot
- Identity/assay/metals/micro reports as scoped
- Non-GMO/organic /allergen statements as scoped
- Third-party testing when required
If COA does not match the locked BOM grade and source pathway, material should not be released into finished production.
By Applications
Use soy isoflavone extract across these finished dosage forms. Open each card for the matching OEM manufacturing page.
Turn standardized soy isoflavone extract into hard-capsule SKUs for the fastest private label and Amazon / DTC launch path.
Fit: Most mainstream soy isoflavone path
Best for: Assay-locked private label · Amazon / DTC first launches
Watch-outs: High-load menopause stacks may need larger shells or split servings
Compress soy isoflavones into coated or custom tablets when you need bone-support mineral stacks and high-count retail economics.
Fit: Mainstream · strongest for bone / mineral stacks
Best for: Soy + calcium + D3 + K2 · high-count retail
Watch-outs: Compression and coating engineering for high-mineral loads
Use softgels as oil-companion or dual-SKU systems — typically Vitamin D3 / K2 twins beside a soy capsule or tablet hero.
Fit: Oil companions / dual-SKU — not the default dry-extract hero
Best for: D3 / K2 twins beside a soy capsule or tablet
Watch-outs: Dry soy extract alone usually stays in capsules/tablets
Build flavored chewable women’s wellness or beauty gummies when lifestyle trial matters more than matching capsule assay targets.
Fit: Growing lifestyle format · higher technical barriers
Best for: Beauty / women’s wellness trial SKUs with realistic mg/piece
Watch-outs: Dose, taste masking, and moisture control must clear before scale
Blend soy isoflavones into drink mixes and premixes for multi-ingredient beauty or wellness formulas that exceed capsule fill limits.
Fit: Multi-ingredient / beauty drink mixes
Best for: Collagen + soy systems · tubs and premix programs
Watch-outs: Mixability and flavor systems must be engineered early
Finish powder formulas into unit-dose sticks or sachets for travel, sampling, and convenience export channels.
Fit: Convenience and export unit-dose
Best for: Travel packs · sampling · stick-ready premix finishing
Watch-outs: Barrier film, fill weight, and print MOQ drive feasibility

| Stack direction | Typical companions | Why brands combine | Where to manufacture |
|---|---|---|---|
| Bone / midlife | Calcium · Vitamin D3 · K2 | Broader midlife SKU than soy alone | Tablets · Capsules |
| Menopause botanical | Black Cohosh · Red Clover | Recognizable aisle architecture | Capsules |
| Mineral support | Magnesium (± D3) | Daily women’s wellness extension | Capsules · Tablets |
| Beauty-from-within | Collagen · HA · Vitamin C | Soy as botanical companion | Powder · Stick Pack · Gummies |
| Hero SKU | Standardized soy only | Fastest private label start | Capsules |
A COA-compliant extract is only the first step. Finished success still depends on format engineering, overage policy, and pack design.
| Process attribute | Practical implication |
|---|---|
| Flowability | Affects capsule fill weight accuracy and blend uniformity |
| Compressibility | Critical for tablets — especially with calcium systems |
| Heat stability | Limits aggressive gummy / hot-process pathways |
| Moisture sensitivity | Pack barrier and storage rules for powders/sticks/gummies |
| Taste | Masking required for powders, sticks, and gummies |
| Color | Can show through clear capsules or light gummy matrices |
| Compatibility | Marker profile, minerals, and botanicals must be co-formulable |

Yes. Ingredient supply connects to finished soy isoflavone supplement manufacturing — private label, OEM, and ODM.
Yes within manufacturable ranges — grade %, marker locks, source pathway, and documentation scope.
Sample and commercial lead times depend on grade availability, documentation scope, and whether finished OEM is included. Confirm after brief review.
Pathway is project-locked to the ordered grade; HPLC standardization and source pathway are stated on documentation. Ask for the process summary with your RFQ.
