3 Ways to Lower Inventory Costs When Starting a Supplement Brand
Key takeaway:
Launching a supplement brand is capital-intensive, with inventory often requiring six-figure investment. Entrepreneurs can reduce this burden by:
Testing demand through on-demand private label drop shipping.
Using stock private label formulas from reputable manufacturers.
Partnering with manufacturers offering lower minimum order quantities (MOQs).
Each option comes with trade-offs in cost, compliance control, and brand differentiation.
Introduction
Starting a supplement brand isn’t cheap. Inventory is by far the largest upfront expense, and a custom formula from a reputable manufacturer with standard minimums can quickly climb into the six-figure range. But founders don’t have to jump straight into high-volume orders. There are models that reduce inventory exposure while still allowing a brand to launch, test demand, and scale.
Here are three proven ways to bring down inventory costs when starting a supplement company—along with the risks you need to know before choosing.

1. On-Demand Private Label Drop Shipping
How it works:
Companies like Rocktomic or Suppl keep unlabeled “bright stock” in their warehouses.
When an order comes through your website, the warehouse applies your label and ships directly to the customer.
You’re charged for the bottle and shipping at the point of sale (plus possible membership or platform fees).
Advantages:
Extremely low startup cost—no need to carry inventory.
Simplified operations; fulfillment and warehousing are handled for you.
Fastest way to test market demand.
Disadvantages:
No control over formula, testing, or quality standards.
You’re fully liable if compliance or safety issues arise.
Risk of backorders, mislabeling, or formula changes outside your knowledge.
Customer service becomes reactive—you rely on the provider to resolve issues.
Bottom line: Drop shipping is the lowest barrier to entry but the highest risk to brand trust and compliance.
2. Private Label Stock Formulas
How it works:
Manufacturers offer stock formulas they either keep in inventory or make to order.
You buy finished product directly from the manufacturer, add your label, and handle fulfillment.
Advantages:
Direct line of sight into your manufacturer’s QA and production.
Ability to visit facilities and review records.
Faster lead times than full custom formulas.
Disadvantages:
Higher per-unit cost than drop shipping.
Often requires minimum order quantities (MOQs).
Limited say in testing protocols, which may not meet Amazon or retailer standards.
Testing may be “FDA-allowed” but not defensible under scrutiny (common with weaker QA programs).
Bottom line: Stock formulas give you more control than drop shipping but may leave gaps in testing rigor and differentiation.
3. Custom Manufacturing with Lower MOQs
How it works:
Some reputable manufacturers accept lower MOQs (1,000–2,500 units vs. 5,000+).
Allows you to develop a custom formula unique to your brand, while reducing initial capital outlay.
Advantages:
Full control over formula, specs, and testing.
Greater ability to differentiate from competitors.
Transparent relationship with the manufacturer.
Disadvantages:
Limited number of manufacturers offer low MOQs.
Per-unit costs are higher, as smaller runs are less efficient.
Some smaller facilities may lack the polish of large operations (though they can still meet FDA standards).
Bottom line: A middle path between affordability and control, best for founders who want uniqueness without full six-figure inventory spend.
Key Takeaways
Inventory is the largest startup cost in supplements, but different models can reduce exposure.
On-demand drop shipping is cheapest, but risks compliance and brand control.
Private label stock formulas balance cost with visibility, though testing rigor varies.
Custom low MOQ manufacturing is pricier per unit but gives founders control, uniqueness, and long-term defensibility.
FAQ
What’s the cheapest way to start a supplement brand?
On-demand private label drop shipping has the lowest upfront cost, since you pay only when orders come in.
Why not just use stock formulas?
Stock formulas lower cost but limit your control over testing and make differentiation difficult. Long-term, custom formulas are stronger.
Can you get custom formulas with small MOQs?
Yes—some reputable manufacturers accept orders as low as 1,000–2,500 units, though per-unit costs will be higher.
Who is legally responsible for compliance in all three models?
Always the brand owner. Even if a drop shipper or manufacturer makes mistakes, FDA and FTC hold the brand accountable.
