Protein powder manufacturers: whey, collagen, private label

Published minimums run from 48 units to 1,250, and the split is stock versus custom

Ask what the minimum order is for private label protein powder and you will get a confident answer from whichever page you opened first. Put the pages side by side and the confidence disappears. Reading each company's own site in September 2026: ViaCore Nutrition publishes as few as 48 bottles on a stock product, Vitalabs publishes a minimum of 72 bottles per SKU, Pure Private Label publishes 144 units, and Makers Nutrition publishes as low as 500. Aligen, Bactolac, and YouBar publish no minimum at all and route you to a quote form.

So four of seven publish a number, and those four span roughly a tenfold range on their own. The spread gets wider once you include custom work, and the most useful single data point on this page comes from one company publishing both ends of it. ViaCore states as few as 48 bottles on a stock product, increasing to 1,250 bottles on a custom formula. Same facility, same equipment, same week. The minimum moved by a factor of about twenty six because of one decision the buyer made.

That is the mechanism nobody spells out on a sales page. A stock formula already exists. The manufacturer has bought the raw material, validated the blend, run the stability study, and holds finished inventory, so your order is really a labeling and packing job. A custom formula means buying raw ingredients in commercial quantities, building and testing a new blend, and dedicating a line, and the minimum has to cover all of that before a single tub ships.

The practical consequence is that the widely repeated advice that you need thousands of units to start a protein brand is answering a question you may not have asked. If your first run is a stock whey with your label on it, several US facilities will start you in the dozens or low hundreds. If you want your own ratio, your own sweetener, and a branded ingredient, expect four figures and plan the cash for it. Deciding stock or custom before you contact anyone is the highest leverage half hour in the whole project, and it is the same trade that shapes minimums across private label manufacturers in every category.

None of the seven publishes a price, so the quote is the only real number

Across all seven manufacturers checked in September 2026, not one publishes a dollar figure for a private label protein powder run. ViaCore shows a From $2.00 placeholder that requires signing in to see anything real. Bactolac's own FAQ answers the pricing question by saying the cost varies with packaging and ingredient costs. The rest point at a quote form or a phone number.

That is a stronger absence than you find in most manufacturing categories. It is not evasion so much as a category where the material is a commodity with a moving price, and the vendors know it. Whey markets move, and a per unit price quoted today against last month's whey is a promise the manufacturer would have to eat.

It does mean the only way to learn your number is to put the same brief in front of several facilities, and that the comparison work falls entirely on you. It also means you should be suspicious of a per unit price offered before anyone has asked your protein type, your grams of protein per serving, your flavor, your tub size, and your quantity. Those five inputs decide the cost, and a number given without them is a marketing figure rather than a quote.

Only one of the seven publishes a lead time. Aligen states a six week turnaround for private label. ViaCore states same day shipping on stock products and only that custom formulas take longer, without saying how much longer. Everyone else is silent. Treat any timeline you are told verbally as a number to get in writing before you plan a launch date around it.

The protein is most of your cost, which is not true of a capsule

In capsules and tablets the ingredients are usually measured in milligrams and the packaging, the bottle, and the labor are a large share of the unit cost. Protein flips that. You are selling twenty to thirty grams of an actual commodity per serving, times twenty five or thirty servings per tub, so a single tub carries roughly a pound and a half of raw material. The protein you choose is the dominant line on your cost sheet, and no amount of negotiating on packaging will move the total the way switching protein does.

This is why whey concentrate and whey isolate produce such different quotes for what looks like the same product. Concentrate runs lower in protein by weight and carries more lactose and fat, isolate is further processed to a higher protein percentage, and the price gap between them is real and persistent. Plant proteins carry their own version of the trade: pea protein is usually cheaper than isolate but has a flavor profile that costs you more in masking, and rice protein is often blended with pea to fix an amino acid gap rather than used alone. Collagen peptides are a separate market again with their own supply and their own claims, and they are not a complete protein, which matters for what you can put on the panel.

Two other things move the cost sheet in ways new brands do not plan for. The first is overage. To guarantee the protein and any actives on your label through the whole shelf life, the manufacturer overfills against the claim, and you pay for material that exists only to keep the panel true at month twenty four. The second is the flavor system. Getting a chocolate whey to taste acceptable in cold water in a shaker bottle is a genuine formulation problem, and sweetener choice, whether you are on sucralose, stevia, monk fruit, or unsweetened, changes both the cost and the length of the development cycle.

When you compare quotes, compare cost per gram of protein delivered rather than cost per tub. Two manufacturers quoting the same price per unit can be selling you meaningfully different products once serving size and protein percentage are accounted for.

Pick your sport certification before you pick your manufacturer

If you plan to sell to athletes, to teams, or into retail chains that ask for it, banned substance certification is not something you add later. It is a facility and batch level program, so it has to be chosen before the run rather than applied to finished inventory sitting in a warehouse.

Three programs matter in the US and they are not interchangeable. NSF Certified for Sport tests for approximately 290 banned substances and is the one with the deepest institutional recognition: it is recognized by the United States Anti-Doping Agency, Major League Baseball, the National Hockey League and the Canadian Centre for Ethics in Sport, and recommended by the NFL, NBA, PGA, LPGA, NASCAR and Ironman among others. Informed Sport, run by LGC Assure and established in 2008, covers more than 285 substances. BSCG Certified Drug Free covers approximately 450, the widest list of the three.

The substance count is the number everyone compares and it is the less important one. The real difference is testing frequency. Informed Sport tests every batch before release and also runs blind off the shelf tests on retail product, and BSCG likewise works on an every lot basis, while NSF Certified for Sport operates on a variable model rather than certifying every single lot. If your buyer is a professional team or a league, recognition is what they will ask about and NSF has the most of it. If your risk is a contaminated lot reaching a customer, per batch testing is what actually reduces it.

Whichever you choose, ask a prospective manufacturer two questions: whether the facility is already enrolled in that program, and whether your specific product would be certified or merely made in a certified facility. Those are different claims and only one of them can go on your label. If your buyer is a retailer rather than an athlete, the equivalent questions are about third party GMP registration and allergen controls, which is the same conversation you would have with a co-packer for any food product.

What to put in a protein powder RFQ so the quotes are comparable

Most protein quotes come back non comparable, and the brief is usually why. Seven lines fix it.

Say stock or custom in the first sentence. It moves the minimum by roughly twenty six times at one of the manufacturers above, so leaving it ambiguous guarantees you get quoted for different things.

Name the protein and the grade. Whey isolate, whey concentrate at a stated percentage, micellar casein, collagen peptides, pea, or a blend with the ratio. This is the largest cost input, so it cannot be left to the manufacturer's assumption.

Give grams of protein per serving and servings per container. Cost per tub is meaningless without both, and it is the only way to compare two quotes on cost per gram of protein delivered.

Specify the format and the closure. A twenty serving tub, a stand up pouch, and a stickpack are three different filling lines, and not every facility owns all three.

State the certifications you need up front, including sport certification, organic, non GMO, gluten free, and kosher or halal. Each one narrows the facility pool before anyone quotes.

Give quantity at two or three volumes. This shows you the price break curve rather than a single number, and on a material driven product the curve is steep enough to change your launch plan.

Ask what the overage assumption is and who owns the stability data. If the manufacturer runs the stability study, ask whether you receive the report, because it is what supports your expiry date if anyone ever asks. If you are sending the same brief to more shops than you want to email by hand, an RFQ tool keeps every response in one comparable place, and the wider question of how to shortlist a facility at all is covered on our supplement contract manufacturers page.
