Safety & Testing
No batch of Rosewyn leaves the facility untested. Every production run is verified with a Certificate of Analysis (COA) — independent confirmation that what the label says is exactly what's in the capsule.
Heavy Metal Testing
Because botanical ingredients grow in soil and water, trace heavy metals can occur naturally. That's why every Rosewyn batch is screened for lead, cadmium, mercury, and arsenic, and confirmed to fall within safe limits:
- Lead: ≤ 6.0 mcg/serving
- Cadmium: ≤ 4.1 mcg/serving
- Mercury: ≤ 2.0 mcg/serving
- Arsenic: ≤ 10 mcg/serving
Microbial Safety
Each batch is also tested for microbial contaminants and must pass before it's released:
- Total Plate Count: Not more than 500,000 cfu/g
- Yeast & Mould: Not more than 10,000 cfu/g
- E. Coli: Absent
- Salmonella: Absent
Transparency
Every lot comes with a signed Certificate of Analysis listing the exact raw materials, the dosage per serving, and the full heavy metal and microbial results. That's not marketing language — it's the same paperwork our manufacturing partner issues for every single batch we make.
