This DAA Acid is derived from a plant-based fermentation process rather than chemical synthesis. Comparative analysis shows that its purity, optical rotation, and batch stability make it highly suitable as a raw material for export-grade supplements. If you have previously used synthetic versions, you will find that this product yields a clearer solution upon dissolution and lacks the characteristic pungent, acidic odor.

FAQ
1. Which countries do you ship to? How are shipping costs calculated?
We have shipped to the USA, Germany, the Netherlands, Poland, Brazil, Australia, South Africa, and others.
Shipping costs are not included in the price quote; a reference price based on actual weight and destination will be provided before you place an order.
Long-term partners can arrange shipments on CIF or FOB (Qingdao/Shanghai) terms.
2. What precautions should be taken for storage?
Keep the container sealed; tie the inner bag tightly immediately after use.
Storage conditions: Cool, dry, and away from light; temperature 15–25°C.
Do not store in the refrigerator (it may absorb moisture and clump).
Do not store together with strong alkalis, strong acids, or chemicals with strong odors.
3. What is the shelf life? Can it still be used after the expiration date?
Unopened: 2 years (see the drum label for the production date).
After opening: Recommended use within 6 months.
Continued use after the expiration date is not recommended; expired DAA Acid must absolutely not be used in human supplements.
