Green Tea L-Theanine supplied by Changsha Vigorous-Tech Co., Ltd. is a natural amino acid extracted from Camellia sinensis leaves. The product is offered in both capsule and powder forms, each batch processed to retain high purity. The supplier states that the extraction follows a natural leaf method without synthetic additives. Certification records list ISO and FSSAI compliance.
In the dietary‑supplement market, L‑Theanine powders commonly contain 95 % - 98 % L‑Theanine by weight and are dried to a moisture level below 5 %. Powder grades are often milled to a particle size around 150 µm to ensure uniform dissolution. Capsules are usually gelatin hard‑capsules of 0.68 ml volume, providing 100 - 200 mg of active ingredient per dose. Such specifications align with standard functional‑food ingredient standards.
The amino acid is used to formulate stress‑relief or focus‑enhancing supplements and is popular among nutraceutical manufacturers. Buyers should confirm the supplier’s minimum order quantity, lead time, and preferred Incoterms such as FOB or CIF before placing an order. Payment options reported include T/T and L/C, but exact terms must be negotiated directly. The product is shipped from ports in China, typically under standard container loads.

Before confirming an order, importers should request the supplier’s latest certificate of analysis and copies of the ISO and FSSAI certificates to verify product quality. It is also prudent to ask for a sample batch to evaluate purity and dissolution characteristics. Clarify any minimum order quantity, packaging specifications, and whether the product is shipped in bulk powder or pre‑filled capsules.
Logistics planning should confirm the departure port in China and the expected transit time to the buyer’s destination. The supplier mentions typical shipping terms such as FOB or CIF, but the exact Incoterm must be agreed in the contract. Lead‑time is not disclosed, so ask for a production schedule and estimated shipment date. Payment methods listed include T/T and L/C; the buyer should verify any advance payment requirements.
Importers are advised to arrange third‑party inspection either pre‑shipment or at the loading port to confirm that the batch meets the agreed specifications. Request a full batch certificate of analysis, moisture and heavy‑metal test results, and a compliance statement with the relevant food‑supplement regulations. Maintaining records of these documents will facilitate customs clearance and assure downstream customers of product integrity.
