Your #1 Dietary Supplement Manufacturer in the USA 🇺🇸

Finally, a Dietary Supplement Manufacturer Built for Entrepreneurs and Growing Brands

If you’ve spent weeks chasing quotes from supplement manufacturers who demand 10,000-unit minimums, refuse to share production timelines, or leave you guessing about FDA compliance, you already know how frustrating this process can be. Most entrepreneurs with promising supplement ideas hit the same wall: massive upfront volume commitments, opaque pricing, and partners who treat emerging brands as an afterthought.

Matsun Nutrition was built to solve exactly that. We deliver custom supplement manufacturing across liquid vitamins, powders, and sea moss, without demanding massive upfront volume commitments or leaving you in the dark about your production timeline. Our team guides you from concept to finished product with full transparency at every stage.

With an FDA-registered, cGMP-compliant facility backed by 30 years of manufacturing expertise and more than 5,000 SKUs developed for over 500 brands worldwide, we bring the infrastructure and experience of a large-scale manufacturer, combined with the responsiveness and personal support your growing supplement brand deserves. The U.S. dietary supplements market was valued at $48.4 billion in 2021, and it continues to grow. There’s room for your brand, and we’re here to help you claim your share.

Why Matsun Nutrition Works

“We built our 2,500-unit entry tier because we saw too many brilliant formulations die simply because a founder couldn’t risk a 10,000-bottle minimum. Our goal isn’t just to manufacture your first run; it’s to provide the flawless infrastructure that takes you from a startup to a nationwide retail brand.”

• Realistic Starting Volumes That Scale – Launch with just 2,500 units to validate your market with minimal risk, then seamlessly scale to our 500k+ daily unit production capacity as demand grows. While most supplement manufacturers require 10,000+ units, our cost-effective entry tier lets you test your supplement ideas without burying capital in unsold inventory.

• Specialized Delivery Methods Focused on Your Needs – We specialize in liquid supplements and powder supplements designed for both human and pet health markets. Powder supplements allow flexible dosing and quick absorption, while liquid supplements are a growing trend due to their even faster absorption and minimal ingredient lists. Additionally, we produce high-quality capsules, tablets, and sea moss supplements to meet consumer demand. Our focused expertise ensures your product is crafted in the ideal form to deliver maximum benefits and consumer satisfaction.

• Fast, Transparent Turnaround Times – Our standard 6–8 week fulfillment from approved concept to delivered product beats the industry average of 16–26 weeks for custom formulations. That faster turnaround means you reach the market while your competitors are still waiting on their first batch.

• True One Stop Shop – From custom formulation and raw material sourcing to graphic design, label compliance, packaging, and Amazon FBA fulfillment, everything happens under one roof. No juggling five different vendors. No finger-pointing when timelines slip.

• 100% US-Based Production – Over 80% of Americans prefer products made in the USA. Our domestic manufacturing ensures better quality control, faster lead times, and transparent supply chains for ingredient sourcing. Manufacturing in the USA reduces shipping delays and customs issues that plague overseas operations. Trusted by over 500+ brands worldwide, with a 500k+ daily unit production capacity.

How It Works

Getting your dietary supplement from concept to customer doesn’t have to be complex. Our process is structured, proven, and designed to eliminate guesswork.

Step 1: Submit Your Formula or Concept

Request a free quote through our streamlined process. Provide your existing unique formula or share your concept, and work with our team on custom formulation services. Whether you have a detailed formula for L-theanine stress support or just a rough idea for a liquid multivitamin, our initial consultation takes minutes, not days. You’ll receive a detailed quote within 24 hours, complete with projected timeline and pricing.

Step 2: Development and Testing

Our in-house analytical and formulation scientists seamlessly guide you through the process of developing or refining your formula without the technical headaches. Custom formulation allows brands to create unique supplement products tailored to specific health needs-whether that’s immunity support, skin health, personal health optimization, or targeted nutrients for stress management.

Expert flavor profiling and taste masking ensure high consumer retention, which is especially critical for liquids and sea moss, where taste can make or break repeat purchase rates. We conduct stability testing, optimize for maximum absorption and potency, and ensure compliance with FDA and NSF guidelines while making great-tasting supplements.

Manufacturers must adhere to the Dietary Supplement Health and Education Act, and our regulatory compliance team fully manages the review of custom labels and packaging to verify strict FDA labeling compliance for you. Labels must state that a product is a dietary supplement and include serving size information-our team handles every detail so you don’t have to.

Step 3: Production and Fulfillment

“Anyone can mix ingredients, but true brand longevity relies on batch-to-batch consistency. We enforce multi-stage raw material testing and issue comprehensive COAs because our clients need to know that their 10,000th bottle will test just as perfectly as their very first pilot batch.”

We manufacture your products in our USA-based, FDA-registered, and cGMP-certified facility. GMP compliance ensures product safety and consistency across every single production run. GMP-certified facilities follow strict safety and hygiene standards, and GMP practices reduce the risk of defective products reaching your customers.

We handle fully managed, multi-stage quality control, including raw material identity testing, 3rd-party independent verification, and comprehensive Certificates of Analysis (COAs) for every single batch. Reputable brands provide Certificates of Analysis for their batches because third-party certifications verify product content and contaminant testing. High-quality manufacturers perform rigorous testing for contaminants, including heavy metals, microbial load, and pesticide residues.

We provide end-to-end fulfillment, including dedicated Amazon support to get your products listed, compliant, and delivered to FBA warehouses without delays.

What Makes Us Different

Most alternatives in the supplement industry focus on features. We focus on outcomes for your business.

• Liquid Vitamin Specialization – As the best liquid vitamin manufacturer and the #1 trusted private liquid supplement manufacturer on Amazon, we bring unmatched expertise in drops, shots, tinctures, and liquid delivery systems that competitors simply lack. We also maintain deep expertise in powders and sea moss supplements.

• Startup-Friendly Batch Sizes – Launch with just 2,500 units, compared to the industry standard of 10,000+ units. Private label supplements require less investment than custom formulations, and our private label supplement options let you validate your market before committing to large inventory.

Our organic supplement manufacturing includes USDA Organic Certified sourcing of non-GMO and organic ingredients, meeting the clean-label expectations that drive modern purchase decisions.

U.S.-based manufacturing ensures better quality control and faster lead times. U.S. manufacturers provide transparent supply chains for ingredient sourcing.

• Amazon Authority – The #1 trusted private liquid supplement manufacturer on Amazon with dedicated FBA setup support. As online marketplaces tighten requirements for third-party verification and COAs, our compliance-first approach means your listings launch without rejection.
