St. John's Wort Supplement Manufacturer

St. John’s Wort extract is not a complete specification. Hypericum perforatum extract quotes are comparable only after the fields below match.

Material Types

Six fields to specify

Botanical → Plant part → Extract type / DER → Marker → Assay method → Solvent / carrier

Extraction solvent belongs on the specification because it affects marker profile and residual solvents. Final specification is project-dependent.

Five procurement rules

1. Define the botanical — Hypericum perforatum L., flowering herb / aerial parts.
2. Define the extract — Powder, ratio, or standardized. Ratio ≠ marker potency. A 10:1 extract is not 10× hypericin.
3. Name the marker — Hypericin ≠ total hypericins ≠ hyperforin. Hyperforin may be a minimum or a maximum.
4. Name the assay method — UV ≠ HPLC. Two lots that both say “0.3%” are different materials if the methods differ.
5. Compare price only after specifications match — $/kg is comparable only after these fields match.

Serving math

Extract weight × assay = marker amount per serving

300 mg × 0.3% hypericins = 0.9 mg hypericins. A 300 mg extract line is not 300 mg hypericin. 300 mg / 500 mg are fill starting points, not a factory daily dose.

Standardized botanical pathways: Standard Extracts.

Before comparing $/kg, match these fields:

If two quotes do not match these fields, the lower price may simply reflect a different material specification.

Confirm classification before you finalize the extract grade. The same botanical can sit on a dietary-supplement label in one market and on a herbal-medicinal-product file in another. The EMA maintains an EU herbal monograph for Hyperici herba; it informs herbal-medicine classification in the EU, not a global food-supplement claim list.

Regulatory checkpoints before formula freeze

1. Product classification — Food supplement vs herbal medicine.
2. Permitted claims — Mood / emotional-wellness structure/function where allowed.
3. Interaction / warning review — CYP3A4 / P-gp concerns are a label issue; literature often discusses them together with hyperforin level. A low-hyperforin grade does not by itself clear interaction language.
4. Hypericin / hyperforin specification — Agree analyte, method, and min vs max before artwork.
5. Finished-label review — Pregnancy, medication-use, and photosensitivity cautions follow market-specific requirements.

KS Nutripharma supports manufacturing feasibility and technical documentation; final classification, claims, and labeling remain the brand owner’s responsibility.

Consistency is built in process — incoming assay, fill, pack, and dating — rather than copied from a drum COA onto the bottle.

01 — Marker stability. Hyperforin may need tighter handling, headspace, and pack than a hypericins-only specification. A photostability check on hypericins is a separate decision.

02 — Odor, color, and sensory. Capsules isolate characteristic herb odor and dark color. Powders and gummies need a sensory and staining plan before artwork.

03 — Flow and fill. Herb powder (F02) and some extracts are low-density. Particle size and equipment set-up are confirmed at sample, especially for F04 mineral stacks.

04 — Packaging and shelf life. HDPE/PET + induction seal is a common capsule/tablet start. Final dating follows formulation, pack, storage, and stability data. Incoming extract stability is not finished-SKU dating.

Humidity, barrier, and dating: Moisture Control & Stability Engineering.

The commercial batch is released against the same approved specification used for the sample: specification → sampling → testing → release.

A usable COA has four blocks: identity, potency (named analyte + named method), safety, and physical. A file that only says “0.3%” without analyte or method is not a comparable grade.

Lab: in-house release; SGS or Eurofins when the RFQ requires it. Methods: Quality Control.

01 RFQ → 02 Market & specification review → 03 Extract specification → 04 Formula → 05 Sample → 06 Pilot → 07 Stability / QC as scoped → 08 Production → 09 Shipment

Target-market review happens before formula freeze.

MOQ and lead time

Final MOQ depends on formula, packaging, testing, and production schedule. A bulk kilogram and a finished capsule SKU are quoted separately.

Subject to pack, testing, and schedule.

Seven fields for a usable RFQ

1. Finished SKU or bulk extract
2. Material type (herb powder / ratio / hypericins / hyperforin min or max / “recommend”)
3. Marker % + HPLC or named method; attach a CoA if matching
4. F01–F09 or BOM
5. Format
6. First PO + annual forecast
7. Country + classification + channel
