L-Theanine Gummy Manufacturer for Calm and Focus

Our Guangdong plant runs two gummy lines with a combined capacity of 120,000 pieces per shift. Depositing tolerates 2.5-4.0 g pieces at 100-200 mg L-Theanine. We cook, deposit, and cure in a humidity-controlled room to prevent sticking. Pectin bases suit vegan and halal markets; gelatin gives a firmer chew. Both run on the same line with a 4-hour changeover.

After curing, gummies pass through a polishing drum and a metal detector. We bottle in 30, 60, 90, or 120 counts, or pack in stick packs and pouches. Bottling lines handle child-resistant caps, induction seals, and desiccant sachets. Retail-ready cartons print lot numbers and expiry dates. Typical run sizes are 5,000-50,000 units per SKU, with repeat orders scheduling in 15-20 working days.

L-Theanine has a mild umami note that can read as savoury in a sweet gummy. We mask it with natural flavours at 0.3-0.8% of the batch. Common profiles are mixed berry, citrus, green tea, and peach. Pectin formulas need a pH of 3.2-3.8 and a soluble solids range of 78-82 Brix. Gelatin formulas set at 76-80 Brix. We adjust the sweetener system to hit a 10-12% sugar load or a zero-sugar claim using allulose or maltitol.

For focus positioning, we can combine L-Theanine with 50-100 mg caffeine, 50-100 mg L-tyrosine, or 25-50 mg Rhodiola extract. Each active is weighed and blended in a separate room to avoid cross-contact. We run a 3-batch taste panel with 5-8 internal tasters before shipping samples. Stability testing at 25°C/60% RH and 40°C/75% RH for 3 months confirms dose retention and texture.

The facility holds GMP, ISO 22000, and HACCP certifications. We can produce halal, and vegan batches where the formula and supply chain allow. Every incoming lot of L-Theanine is tested for identity, assay, heavy metals, and microbials by an ISO 17025 lab. Finished gummies are tested for dose uniformity, water activity, and total plate count. Certificates of analysis ship with each batch. We are an FDA-registered facility for US-bound orders.

From Guangdong, sea freight to Los Angeles takes 18-25 days; to Rotterdam, 28-35 days. Air freight is 5-8 days. We handle export documents, including commercial invoice, packing list, and certificate of origin. For Middle East orders, we provide halal certificates and Arabic labelling. Minimum order for retail bottling is 1,000 units per SKU. pilot volumes are discussed case by case for market testing, with a 10-15 day sample turnaround.

Every L-Theanine gummy batch is tested at three stages: incoming raw material, in-process gel, and finished product. The L-Theanine raw material is verified for identity by FTIR and assay by HPLC to confirm 98% or higher purity. Microbial testing covers total plate count, yeast and mould, E. coli, and Salmonella, with limits set to USP or EP standards. Heavy metals (lead, arsenic, cadmium, mercury) are tested by ICP-MS. Disintegration testing follows the USP <2040> method for gummies, ensuring the piece breaks down within 30 minutes in simulated gastric fluid.

In-process checks occur at the gelatin or pectin gel stage, where we verify pH, Brix, and viscosity before depositing. After curing and drying, finished gummies are sampled per lot for potency, which must fall within 90-110% of the label claim for L-Theanine. Each batch receives a certificate of analysis (COA) that lists the test parameters, methods, specifications, and results. The COA also includes the batch number, production date, expiry date, and a statement of conformity. We retain samples from every batch for 24 months in a temperature-controlled archive.

Stability protocols follow ICH guidelines. We run accelerated stability at 40°C and 75% relative humidity for six months, with testing at 0, 1, 2, 3, and 6 months. Real-time stability at 25°C and 60% relative humidity runs for 24 months, with testing every three months. Parameters include potency, microbial count, colour, texture, and water activity. These data support the shelf life declared on the label, typically 18 to 24 months. For custom formulations, we can adjust the stability protocol to match your target market requirements.

We offer several packaging formats for L-Theanine gummies: HDPE bottles with induction seals and child-resistant caps, blister packs, stick packs, and sachets. Bottle sizes range from 60 cc to 500 cc, holding 30 to 120 gummies. Stick packs and sachets are ideal for single-serve dosing and travel retail. All packaging materials are food-grade and meet FDA and EU food-contact requirements. We can supply bottles with desiccant canisters or oxygen absorbers to extend shelf life, depending on your stability data.

For the US market, we design labels that comply with FDA dietary supplement labelling rules. This includes a supplement facts panel with the L-Theanine amount per serving, other ingredients list, allergen statement, and the mandatory “Distributed by” or “Manufactured for” statement. We also include lot code and expiry date in a legible format, either printed inline or via inkjet. For Amazon sellers, we can apply FNSKU labels and poly-bag each bottle before cartoning. Cartons are standard corrugated with a maximum weight of 20 kg per carton, and pallets are 1.2 m by 1.0 m, stretch-wrapped and labelled per your requirements.

Retail readiness extends to compliance documentation. We provide a finished-product specification sheet, a packaging specification, and a label proof for your approval before printing. For EU markets, we can include the address of the responsible person and comply with EFSA health claim rules. We do not print claims that are not authorised. If you need a free-sale certificate or a certificate of origin, we can arrange these through our local chamber of commerce. All artwork is checked against your market’s labelling regulations before mass production.

The sampling process starts with a brief: you provide the target dose, base preference, flavour, colour, and packaging format. We produce a sample batch within 7 to 10 working days. Sample costs vary by complexity and are credited against the first mass production order. Once you approve the sample, we issue a proforma invoice with the MOQ, typically 1,000 units per SKU for retail bottling. Pilot runs from 1,000 units are available at a higher per-unit cost. Mass production takes 20 to 35 working days after sample approval and receipt of deposit.

Shipping options depend on your timeline and budget. Air freight takes 5 to 10 days door-to-door and suits pilot runs or urgent replenishments. Sea freight takes 25 to 40 days port-to-port, with LCL or FCL options. We ship from Shenzhen or Hong Kong ports. Incoterms offered are EXW, FOB, and DDP. For DDP, we handle customs clearance and delivery to your door, including duties and taxes where applicable. We provide a commercial invoice, packing list, bill of lading or air waybill, COA, MSDS, and a free-sale certificate upon request. Phytosanitary certificates are not applicable for gummies but can be arranged for herbal extracts if needed.

We recommend booking production slots at least six weeks ahead of your desired delivery date, especially for Q4 retail seasons. For repeat orders, we keep your formula and packaging artwork on file, which shortens the lead time to 15 to 20 working days. Payment terms are typically 30% deposit with the balance against a copy of the shipping documents. We accept T/T and can discuss other terms for established customers.
