Our commitment doesn't end with the first batch. From day one, Wellgreen works with you across your product's full lifecycle - keeping quality consistent, performance on track, and our partnership built for the long term.
Our support doesn't end at delivery. Wellgreen works with you across your product's full lifecycle - stability monitoring, performance evaluation, formula adjustments, batch optimization and one-on-one expert consultation - each with a dedicated point of contact who knows your product history.
Reach us any time through the channels at the bottom of this page; we will agree the execution plan for your specific product together before we start.
We track the key performance indicators of your ingredient across its shelf life and under real storage conditions.
What's included: monitoring parameters tailored to your product (e.g. assay/potency, moisture, appearance), a review cadence agreed with you, and results delivered in a clear report.
When it applies: routine monitoring during long-term supply, or when storage conditions change.
We assess how your ingredient performs in its real application - dosage levels, delivery methods and expected results.
What's included: an evaluation protocol designed together with your R&D team, clearly defined metrics, and actionable results and recommendations.
When it applies: new product introductions, supplier benchmarking, or application changes.
We refine formulations based on your feedback or market requirements.
Confidentiality: your formulation and application details are treated as business confidential and covered by the same confidentiality commitments as your supply agreement.
How it works: share your feedback → internal evaluation → adjusted proposal and sample → acceptance criteria agreed with you → updated batch production.
When it applies: sensory improvements (taste, solubility), cost optimization, or regulatory and market changes.
We make targeted improvements to future production runs to strengthen batch-to-batch consistency.
What's included: lessons from after-sales work are captured into production records and process parameters, reducing batch variation over time.
When it applies: long-term supply programs and orders with strict consistency requirements.

Q1. How can I request stability data or technical documentation for my Wellgreen ingredient?
A: Contact your account manager or email liu@wellgreenxa.com with your product name and batch number. Wellgreen will provide the available stability data, COA and technical documentation and confirm timing with you directly.
Q2. Can I get a re-issued Certificate of Analysis for a past batch?
A: Yes. Wellgreen retains complete records for every shipment - request a COA re-issue through your account manager with the batch number printed on the original label.
Q3. What storage conditions does Wellgreen recommend for botanical extracts?
A: Store in a cool, dry place away from direct sunlight, keep containers sealed, and use within the shelf life stated on the COA. Our technical support can confirm conditions for your specific extract format.
Q4. How does a formula adjustment or custom reformulation request work?
A: Share your feedback with your account manager or R&D contact. Wellgreen evaluates the request, proposes adjustments, provides an updated sample, and agrees acceptance criteria with you before the next production batch.
Q5. How long does a typical reformulation iteration take?
A: Timelines depend on the scope of change and validation requirements. Wellgreen confirms a lead time with you before starting, and prioritizes iterations that affect an existing supply schedule.
Q6. Is my formulation or application information kept confidential during after-sales support?
A: Yes. Wellgreen treats customer formulations and application details as business confidential, and technical discussions are covered by the same confidentiality commitments as your supply agreement.
Q7. What information should I prepare when reporting a quality or performance issue?
A: Product name, batch number, delivery date, storage history and a description of the observed issue (photos or test data if available). Preparing these speeds up root-cause analysis and corrective action.
Q8. Can I request samples of an optimized or reformulated batch before full production?
A: Yes. Every after-sales optimization includes a sample validation step with your team before Wellgreen proceeds to full batch production.
