Q: Can it be shipped via SF Express? How long will it take?

A: Yes, we exclusively use SF Express for all orders to ensure the maximum probiotic activity. All products are shipped in insulated packaging and sent via SF Land Transportation (standard for powder products). Estimated delivery times: Shandong: Next day Jiangsu, Shanghai, Zhejiang, Anhui, Beijing, Tianjin, Hebei: Next day Fujian, Jiangxi, Guangdong, Henan, Hunan, Hubei, Shaanxi, Shanxi, Liaoning, Jilin, Heilongjiang: 3 days Guangxi, Hainan, Inner Mongolia, Ningxia, Qinghai, Gansu, Sichuan, Guizhou, Yunnan, Chongqing: 3-4 days Xinjiang, Tibet: 4-5 days Hong Kong, Macau: 5-7 days

Q: How to ensure the probiotics to remain active during shipping?

A: We use a three-layer cold-chain protection system to maintain optimal freshness: Primary Cooling: Microbe-specific, high-polymer cold packs. Insulated Liner: A triple-layer bag made from 600D Oxford cloth, 0.5cm EPE foam, and 16S PEVA biodegradable film. Protective Outer Box: A high-density, shock-absorbent foam cooler. Products are stored frozen before shipment and remain cool throughout transit, ensuring the strains to arrive alive and keep effective.

Q: Will the product's effecacy be affected if the ice pack melts during shipping?

A: No. We use German high-molecular-weight polymer cold packs with our triple-layer insulation system to maximize cooling duration. While ice packs may melt in extreme heat, our probiotics use an 8-layer microencapsulation technology for heat resistance. We also add an extra 20% viable bacteria at production. This ensures that the loss of live cultures is less than 3% even after 7 days in transit, so the product's effectiveness remains largely unaffected.
