Pure Nature Resveratrol Powder, supplied by our brand Landnutra, is a botanical extract standardized to ≥98% trans‑resveratrol derived from Polygonum cuspidatum root through a clean water‑ethanol extraction - no synthetic solvents, no harsh acids, no chemical modification. The result is a free‑flowing, off‑white crystalline powder that retains trace levels of naturally co‑occurring polyphenols, giving it a more complete plant profile than synthetically produced resveratrol. We offer both standard and micronized grades, the latter with a D90 ≤15 μm for superior dispersibility in aqueous systems like functional beverages and topical serums. Every batch is tested for trans‑resveratrol potency, emodin (kept below 0.5%), heavy metals, and microbial limits, and ships with a full certificate of analysis. For brands that prioritize clean‑label ingredients and transparent supply chains, Pure Nature Resveratrol Powder provides a reliable, nature‑identical active backed by 15+ years of botanical refinement.
