Sports Nutrition Manufacturer for Custom and Private Label Brands
GMP-certified pre-workout, protein, creatine, BCAA, and electrolyte production starting at 2,500 units, with UPLC/HPLC testing and a COA on every batch.
Why Brands Choose NutraSeller as Their Sports Nutrition Manufacturer
NutraSeller is a sports nutrition manufacturer built for brands that need production precision and supply chain speed. As a sports nutrition contract manufacturer, we operate from a 100,000+ square foot FDA-registered facility with current GMP certification, running UPLC, HPLC, and FTIR testing on every batch before it ships.
We produce the full range of sport supplements: pre-workout formulas, protein powders, creatine products, BCAA and amino acid blends, electrolyte hydration formulas, fat burners, and recovery blends. Every product ships with a Certificate of Analysis documenting potency, purity, and microbial safety.
Our minimum order starts at 2,500 units for most formats, with a minimum project investment of $10,000. That is low enough for a first-time brand testing a single SKU on Amazon, yet our facility handles runs of 100,000+ units for established brands scaling across Amazon FBA, Shopify DTC, TikTok Shop, Walmart, and retail.
We sign an NDA before any formulation discussion begins. Your formula, your brand positioning, and your ingredient sourcing strategy stay confidential from the first phone call. As a sports nutrition supplement manufacturer and BCAA manufacturer, we handle formulation, production, testing, packaging, and labeling for every category under one roof. We produce private label sports nutrition products for brands at every stage, from first-time founders testing a single SKU to established companies scaling across channels. No outsourced steps. No split accountability.

NDA Before Any Discussion
Your formulation, ingredient ratios, and brand strategy are protected from the first conversation. Standard policy, not an add-on.
2,500-Unit MOQs
Low minimums across powders, capsules, gummies, softgels, and liquids. Test a product before committing to large-scale production.
6 to 8 Week First-Order Lead Time
Stock formula capsules, powders, and liquids ship in 6 to 8 weeks. Reorders drop to 4 to 6 weeks.
Sports Nutrition Manufacturing Formats and MOQs
Five production formats for pre-workout, protein, creatine, BCAA, electrolyte, and custom sport supplements. Transparent MOQs and lead times on every format.
Powders
Pre-workout blends, protein mixes, creatine monohydrate, BCAA formulas, and electrolyte powders. As a sports nutrition powder manufacturer and protein powder manufacturer, NutraSeller produces the most requested format in the category. We produce instantized powders that dissolve cleanly in cold water without clumping. Custom flavor development is available for every powder manufacturing project. All batches include UPLC/HPLC potency verification and a COA. Ready-to-launch formulas ship in 6 to 8 weeks.
Capsules and Tablets
Pre-workout capsules, amino acid blends, fat burners, creatine caps, and stimulant-free recovery formulas. As a sports supplement manufacturer, NutraSeller’s capsule manufacturing uses both gelatin and HPMC (vegan) shells, with tablet options for ingredients that benefit from higher compression density. Each 60-count bottle is filled, sealed, and labeled in our facility. Capsules and tablets are ideal when exact dosing per serving matters more than taste or mixability. Reorders ship in 4 to 6 weeks.
Gummies
Electrolyte gummies, creatine gummies, amino acid chewables, and recovery formulas. Gummies are growing fast in the casual fitness market, pulling in consumers who skip powders and capsules. Taste masking is critical with performance ingredients, and poor flavoring kills repeat purchases. NutraSeller’s gummy vitamin manufacturing process includes dedicated flavor R&D and stability testing. Stock formulas start at 2,500 units. Custom gummy formulas require approximately 8,333 units due to mold setup and curing cycles.
Softgels
Fish oil sport blends, CLA, MCT oil, and omega-3 performance formulas. Softgels are the right format for oil-based sports nutrition ingredients that cannot be compressed into tablets or blended into powders. NutraSeller produces both stock and custom softgel formulas with in-house encapsulation. Stock softgels start at 2,500 units, while custom formulations begin at approximately 5,000 units. The longer 12 to 14 week first-order lead time reflects encapsulation and curing requirements specific to this format.
Liquids and Shots
L-carnitine shots, liquid aminos, concentrated pre-workout liquids, and electrolyte shots. Liquid formats deliver fast absorption and work well for single-serve packaging sold at gym counters, convenience stores, and online. Standard liquid supplements start at 2,500 units. Shots have a higher MOQ of 25,000 units because of filling line setup and minimum batch sizing for small-format bottles. All liquid production follows the same UPLC/HPLC testing and COA protocol as every other format NutraSeller produces.
Sports Nutrition Ingredients We Manufacture With
NutraSeller manufactures sports nutrition supplements using pharmaceutical-grade raw materials sourced from verified suppliers. Every ingredient undergoes FTIR identity testing at our facility before it enters the production line. No material is accepted without verification.
We work with performance ingredients across every sports nutrition category: stimulants and pump compounds for pre-workouts, complete protein sources for muscle building, creatine variants for strength, branched-chain amino acids for recovery, and electrolyte minerals for hydration. Recovery blends incorporate L-glutamine, taurine, and adaptogens like ashwagandha.
If your formula calls for an ingredient not listed here, our R&D team sources and qualifies new materials regularly. Custom ingredient stacks are developed during the formulation phase, with stability testing to confirm compatibility between compounds. We also offer keto-friendly formulations using BHB salts and MCT oil, as well as vegan-certified sports nutrition products using plant-derived amino acids and HPMC capsule shells.
Get Your QuoteSports Nutrition Categories We Manufacture
Six core product categories manufactured from a single facility. Each links to a dedicated page with category-specific formulation details, MOQs, and ingredient options.
Pre-Workout Formulas
Stimulant and stimulant-free formulas built around caffeine anhydrous, beta-alanine, citrulline malate, L-theanine, and Alpha-GPC. Available in powders and capsules. We handle custom stim stacks with precise dosing verified by UPLC testing on every batch. Pre-workout is the highest-margin category in sports nutrition, and accurate dosing is what separates repurchase-worthy products from one-and-done purchases.
Pre-workout manufacturing →Protein Supplements
Whey protein isolate, whey concentrate, pea protein, collagen peptides, and custom plant blends. Protein powders are the volume driver for most sports nutrition brands, and flavor quality determines whether a customer reorders. NutraSeller develops custom flavor profiles with full stability testing and produces batches from 2,500 units. We also manufacture protein in capsule and bar-ready powder formats.
Protein manufacturing →Creatine Products
Creatine monohydrate, creatine HCl, and buffered creatine in powders, capsules, and gummies. Creatine is one of the most research-backed sports nutrition ingredients on the market, and demand continues to grow year over year. NutraSeller produces unflavored creatine monohydrate and custom-flavored creatine blends that combine creatine with electrolytes, BCAAs, or other performance compounds for differentiated SKUs.
Creatine manufacturing →BCAA and Amino Acid Blends
Branched-chain amino acid formulas in 2:1:1, 4:1:1, and 8:1:1 leucine-to-isoleucine-to-valine ratios. Available in instantized powders, capsules, and gummies. Fermented plant-based and synthetic sourcing options let you position for vegan or cost-optimized markets. Instantized powder processing is standard on all BCAA powder production runs, because clumpy amino acid powder generates negative reviews and returns.
BCAA manufacturing →Electrolyte Formulas
Sodium, potassium, magnesium, and calcium blends for hydration products targeting athletes, outdoor workers, and active consumers. Available in powders, stick packs, gummies, and liquid shots. Electrolyte products are trending on TikTok Shop and Amazon, and the low ingredient cost makes them one of the highest-margin sports nutrition categories. NutraSeller produces electrolyte mixes with or without added vitamins, BCAAs, or caffeine.
Electrolyte manufacturing →Custom Sport Powder Blends
Any combination of performance, recovery, and hydration ingredients in a custom-formulated powder blend. As a custom sports nutrition manufacturer, this is where we help brands build differentiated products that do not fit neatly into a single category. A pre-workout with added creatine and electrolytes. An intra-workout with BCAAs, taurine, and coconut water powder. NutraSeller’s R&D team formulates, stability-tests, and produces custom blends with full COA documentation on every batch.
Custom powder manufacturing →How Our Sports Nutrition Manufacturing Process Works
Six steps from signed NDA to shipped product. Whether you need a pre workout manufacturer, a creatine producer, or a full multi-category line, every phase happens in our 100,000+ sq ft facility.
NDA and Consultation
Every project starts with a signed NDA. We review your target market, product concept, desired format, and sales channel strategy before recommending a formulation approach. Nothing moves forward until your IP is protected.
Formula Development
Choose a ready-to-launch formula or work with our R&D team on a custom formulation. Custom ingredient stacks, flavor profiles, and dosing are developed and tested during this phase. Custom work adds 4 to 6 weeks for R&D and stability verification.
Raw Material Sourcing
We source pharmaceutical-grade raw materials from verified suppliers and run FTIR identity testing on every incoming ingredient before it enters production. No material is accepted without confirmed identity and purity documentation.
Production and Blending
Your formula moves to our production floor. Powders are blended and instantized. Capsules are filled and polished. Gummies are molded and cured. Softgels are encapsulated. Every format follows GMP protocols with batch tracking throughout.
Quality Testing and COA
UPLC and HPLC testing confirms active ingredient potency against label claims. Microbial, heavy metal, and stability testing complete the quality panel. A Certificate of Analysis is generated for every batch and ships with your order.
Packaging and Fulfillment
We handle bottle filling, labeling, shrink banding, and case packing. Products can ship directly to your warehouse, Amazon FBA fulfillment centers, or retail distribution partners. All packaging meets channel-specific requirements.
Quality Standards Behind Every Sports Nutrition Batch
Every sports nutrition supplement that leaves NutraSeller’s facility has been tested, documented, and verified before it ships. This is the production standard, not an optional upgrade.
Our facility is FDA-registered and holds current GMP certification. We run three types of analytical testing in-house: UPLC for precise active ingredient quantification (caffeine in pre-workouts, creatine per serving, leucine content in BCAAs), HPLC for potency verification across complex formulas, and FTIR for raw material identity confirmation before any ingredient enters the blending room.
Certificate of Analysis on Every Batch
Documents potency per serving, microbial results (total plate count, yeast, mold, E. coli, Salmonella), heavy metals (lead, arsenic, cadmium, mercury), and allergen verification. Ships with every order at no additional cost.
Amazon-Ready Documentation
Amazon requires third-party testing proof for supplement listings. NutraSeller’s COA meets these requirements, so you do not need a separate lab to generate compliance paperwork after production. Read more about selling supplements on Amazon in 2026.
NDA Protection from Day One
Your formulation details, ingredient ratios, proprietary blends, and brand strategy are protected from the first conversation. No exceptions.

What Sports Nutrition Brand Owners Say
Real production results from NutraSeller clients launching pre-workout, protein, electrolyte, and multi-format sports nutrition lines.
We had a custom pre-workout formula with a unique stimulant stack, and our previous manufacturer kept getting the caffeine dosing inconsistent between batches. Some customers said it was too strong, others said it was weak. NutraSeller’s UPLC testing caught the dosing variance on the first test batch and corrected it before full production. Six months in, zero complaints about inconsistency and our Shopify repeat purchase rate jumped 22 percent.
We launched with a single protein powder on Amazon and needed to expand into electrolytes and creatine within the same quarter. Other manufacturers we contacted wanted separate MOQs and timelines for each product. NutraSeller produced all three SKUs on a single production schedule with matching label design. We went from one product to three in 10 weeks and kept our total investment under $35,000.
Running three separate manufacturers for capsules, powder, and gummies was a logistics nightmare. Labels did not match, Supplement Facts panels were inconsistent, and deliveries never aligned. NutraSeller produced all three formats under one roof with matching label design and synchronized shipping. We launched the entire sports nutrition line in one quarter and cut our procurement overhead significantly.
Sports Nutrition Manufacturer FAQ
What formats can a sports nutrition manufacturer produce for my brand?
NutraSeller produces sports nutrition supplements in five primary formats: powders, capsules, tablets, gummies, and softgels. Powders are the most common for pre-workouts, protein blends, creatine, and electrolytes because they allow flexible serving sizes and fast absorption. Capsules and tablets work well for amino acid isolates, fat burners, and stimulant-free recovery formulas where precise dosing matters. Gummies are gaining traction with casual fitness consumers who prefer a flavored chewable over mixing a drink. Softgels suit oil-based ingredients like CLA, MCT oil, and omega-3 sport blends. Liquid shots are also available for concentrated formulas like L-carnitine. Every format ships with a Certificate of Analysis.
What types of supplements does a sports nutrition manufacturer produce?
NutraSeller manufactures the full range of sports nutrition supplements: pre-workout powders and capsules, protein powders (whey isolate, whey concentrate, pea protein, collagen), creatine monohydrate products, BCAA and amino acid blends, electrolyte hydration formulas, fat burners, and recovery blends. Each category is available in multiple formats. We also produce custom formulations that combine ingredients across categories, like a pre-workout with added creatine and electrolytes. Every product type follows the same GMP production standards and ships with a Certificate of Analysis documenting potency and purity.
What is the minimum order quantity to start with a sports nutrition manufacturer?
NutraSeller’s minimum order quantity for sports nutrition supplements starts at 2,500 units across most formats. For powders (pre-workout, protein, creatine, electrolytes), that means 2,500 bags or tubs. For capsules and tablets, it is 2,500 units of 60-count bottles. Stock gummy formulas start at 2,500 units, while custom gummy formulas require approximately 8,333 units. Softgels begin at 2,500 for stock formulas and roughly 5,000 for custom formulations. Liquid shots have a higher MOQ of 25,000 due to production line setup requirements. The minimum project investment across all formats is $10,000.
How long does production take with a sports nutrition manufacturer for a first order?
First-order lead times at NutraSeller depend on the format, not the supplement category. Capsules, tablets, powders, and liquids typically take 6 to 8 weeks from purchase order to shipment, whether you are producing a pre-workout, protein powder, creatine blend, or electrolyte mix. Gummies and softgels require 12 to 14 weeks for an initial run because of longer curing and encapsulation cycles. Reorders are faster: 4 to 6 weeks for capsules, tablets, powders, and liquids, and 6 to 8 weeks for gummies and softgels. Custom flavoring or new formulations add 4 to 6 weeks for R&D and stability testing.
Can a sports nutrition manufacturer create custom flavors for sport powders and gummies?
Yes. Custom flavor development is one of the most important steps in sports nutrition powder and gummy production. NutraSeller’s R&D team develops flavor profiles from scratch for pre-workouts, protein powders, creatine blends, electrolyte mixes, and BCAA formulas. Options include tropical, berry, citrus, chocolate, vanilla, and unflavored profiles. The process includes multiple rounds of taste testing and a stability study to confirm the flavor holds over the product’s shelf life. Custom flavor work adds 4 to 6 weeks to your timeline. If speed matters, NutraSeller offers ready-to-launch formulas with pre-developed flavors that ship in 6 to 8 weeks.
What third-party testing should I expect from a sports nutrition manufacturer?
NutraSeller runs UPLC, HPLC, and FTIR testing on every batch regardless of the supplement category. UPLC and HPLC verify that active ingredient concentrations match the label claim, whether that is caffeine in a pre-workout, creatine monohydrate per serving, or protein content in a whey isolate. FTIR confirms raw material identity before production begins. Every finished batch ships with a Certificate of Analysis documenting potency, purity, heavy metals screening, and microbial testing results. This documentation is essential if you sell on Amazon, which requires third-party testing proof for supplement listings.
Does your sports nutrition manufacturer facility handle allergen-free and vegan formulations?
NutraSeller produces both allergen-free and vegan sports nutrition supplements across every category. For vegan protein products, we work with pea protein, rice protein, and plant blends. Vegan BCAA products use fermented plant-based amino acids. Capsule shells can be switched from gelatin to HPMC for a fully vegan finished product. Allergen-free production requires dedicated line scheduling and thorough equipment cleaning between runs to prevent cross-contamination. If your brand targets the vegan or allergen-conscious athlete market, specify these requirements during the quoting process so we can confirm ingredient sourcing and production scheduling.
What packaging options work best for selling sports nutrition supplements on Amazon FBA?
For Amazon FBA, your packaging must meet specific prep requirements regardless of supplement type. Powders like pre-workouts, protein, creatine, and electrolytes sell best in sealed tubs or stand-up pouches with resealable zippers, and every unit needs a scannable UPC barcode and Amazon FNSKU label. Capsules and tablets should ship in HDPE or PET bottles with induction-sealed caps and shrink bands for tamper evidence, since Amazon may reject units without these features. All supplement labels must include a complete Supplement Facts panel, manufacturer information, and a Made in USA declaration if applicable. NutraSeller handles label design and packaging sourcing as part of production.
