OEM Business

OEM

Ryusendo offers OEM services for clients in the supplement and general food industries, combining the reliability unique to a raw material manufacturer with ease of product development and production.

Leveraging our extensive experience as a raw material supplier, we provide OEM solutions that ensure product quality, regulatory compliance, and smooth commercialization – from concept to finished product.

OEM Development Flow

Feel free to contact us at any stage

You are welcome to contact us even if you do not yet have a finalized formulation, such as:
・“I would like to develop a supplement using this ingredient.”
・“Is it possible to commercialize a product utilizing this raw material?”

We support a wide range of categories, including Foods with Function Claims, supplements (health foods), and general foods.

We also welcome inquiries for small-lot test sales or prototyping prior to brand launch.

As a raw material manufacturer working with numerous companies, we are well positioned to provide consultations that take into account the unique circumstances and challenges of the food industry.

Clarifying your concept and target together

We carefully discuss your brand concept, target consumers, sales channels (mail order, retail, export, etc.), and preferred dosage forms (tablets, capsules, granules, beverages, etc.).

At this stage, we also confirm your expected functionality, price range, development schedule, and anticipated lot size.

From the perspectives of the supplement, general food, and pharmaceutical-related industries, we propose realistic and feasible product designs.

Our expertise as a raw material manufacturer enables smooth development discussions focused on maximizing ingredient characteristics and effectively incorporating scientific evidence.

Secure information management

We can execute a Non-Disclosure Agreement (NDA) prior to the sharing of confidential information, such as original formulations or development concepts.

This allows projects involving multiple departments – such as R&D and marketing – to proceed with confidence.

We centrally manage both raw material and product information under a highly developed information management system, ensuring strict confidentiality.

Balancing efficacy and manufacturability

Based on information obtained during consultation, we design formulations aligned with your objectives, comprehensively considering:

・Expected functionality
・Ease of consumption and long-term adherence
・Cost balance
・Regulatory compliance and labeling requirements

As a raw material manufacturer, we select ingredients while evaluating active component content, stability, compatibility, and supply reliability.

We design formulations considering industry requirements for functional foods, supplements, and general foods.

Our deep understanding of raw materials allows us to achieve a high-level balance between ideal product concepts and manufacturing feasibility.

Verifying actual product quality

We create small-batch prototypes based on formulation.

We verify appearance, flavor, solubility, ease of continued consumption, and physical properties (hardness, disintegration, etc.), making adjustments as needed.

These samples can also be used for internal evaluation or consumer monitoring.

By considering factors such as particle size, flowability, and compressibility, we help minimize risks during scale-up to mass production.

Enhancing brand value

We propose packaging solutions suited to product characteristics and distribution channels, including bottles, aluminum pouches, stick packs, and gift boxes.

We can coordinate with design agencies or adjust existing designs.

We also provide support for listing labeling content (ingredients, nutritional information, warnings, recommended daily intake, etc.) in compliance with regulations.

Our knowledge of raw materials enables us to propose packaging that effectively communicates product value.

Stable quality and supply

We handle diverse dosage forms (tablets, capsules, granules, powders, drinks, etc.) in full-scale production.

We implement integrated production management from filling to packaging.

We establish systems essential for stable supply, such as lot planning, raw material procurement, and inventory management.

We handle scale-ups from small lots to full-scale production flexibly.

By supporting the entire process from raw material supply onward, we ensure stable raw material supply × stable product production.

Consistent quality assurance

We conduct various inspections from adoption of raw material, intermediate processes to final products.

・Physical property tests (appearance, weight, hardness, disintegration, etc.)
・Component analysis
・Microbial analysis

We propose quality standards tailored to meet requirements of various industry and sales channel.

We can provide analysis results and various data upon request.

With cultivated analytical skills as a raw material manufacturer, we ensure traceability and quality from raw material level.

As a Partner for Long-Term Collaboration

We deliver products to your desired destination on schedule.

After delivery of the first lot, we propose and adjust production of subsequent lots based on sales performance.

We also provide ongoing support for product renewal, new product development, and long-term brand growth.

Rather than acting as a one-time manufacturer, we serve as a long-term partner supporting your brand from both raw material and product perspectives.

OEM Consultation & Inquiries

We welcome inquiries at any stage – even if you are simply gathering information or have only a rough concept.
With our expertise as a raw material manufacturer, Ryusendo provides tailored proposals to fully support your brand development and product commercialization.
