A step-by-step guide for entrepreneurs and Amazon sellers entering the liquid supplement market
By Marcus Holt | Updated June 2025
I've been in the supplement space for over a decade, and honestly the shift toward liquids has been one of the more interesting trends I've watched up close. The global liquid supplements market is projected to hit around $8.2 billion by 2028, growing roughly 7-8% annually. And if you're on Amazon or running a DTC brand, you've probably noticed the shelves getting crowded with shots, syrups and drops.
The reason is simple: consumers absorb liquids faster, they're easier to take (especially for older buyers and kids), and brands can differentiate much more easily with flavor, format and packaging than with yet another white capsule bottle. For new brand founders, that's actually a real opportunity right now.
This sounds obvious but most people skip it or do it too quickly. The more specific you are about who you're selling to, the easier everything downstream becomes - formula selection, packaging design, copywriting, ad targeting, all of it.
A few segments that are performing well right now:
Pick one and get specific. "Health supplements for women" is not a niche. "Collagen drinks for women 40+ who care about skin elasticity" is a niche.
This is usually the first real decision you'll make when you talk to a manufacturer, and it matters a lot for timeline and budget.
Private label means you take an existing formula, put your brand on it and go. The advantages are real: lower upfront cost, faster time to market (sometimes 3-4 weeks), and no R&D risk because the formula is already proven. The tradeoff is that your product isn't unique, another brand could be running the same formula under a different label.
For first-time brand builders, this is almost always the smarter starting point. Validate your market first, then invest in differentiation. You can see what ready-to-brand formulas are available here to get a sense of what's in the catalog.
Custom means your manufacturer's R&D team develops a formula to your specs. You get something proprietary, but the process takes longer (8-16 weeks typically) and costs more upfront in development fees. This makes sense once you have proof of demand and you know exactly what your customer wants.
If you want to go custom from the start, here's how the custom formulation process works at Nutrilab.
Not all manufacturers are built the same, and this is where a lot of brands get burned. For liquid supplements specifically, you need a facility that actually specializes in liquids, not one that does capsules primarily and has a filling line in the back.
The non-negotiables: GMP compliance (audit in progress), FDA registration, sterilization capability (autoclave), and a real quality control process with third-party COA testing. We wrote a more detailed guide on how to evaluate and choose a liquid supplement manufacturer if you want to go deeper on this.
Minimum Order Quantity for liquid supplements is typically driven by kettle size. A standard kettle holds roughly 400 units, so most manufacturers set MOQ at 1,200 units (3 kettles). Nutrilab's MOQ is 1,200 units, which is on the lower end for US-based facilities.
A rough budget for your first 1,200-unit run of a 2oz shot:
Total first run: somewhere around $4,500-6,500 depending on formula and packaging choices. We cover this in a lot more detail in the MOQ and pricing guide here.
FDA has specific requirements for supplement labels and a lot of new brands get caught out by this. At minimum you need: product name, net quantity, Supplement Facts panel with serving size and ingredient list, manufacturer name and address, and any required warnings. Your manufacturer should either handle this or at least review your label before production.
The typical Amazon launch sequence: start at MOQ (1,200 units), run PPC to get initial reviews, watch your conversion data, adjust and reorder at 2,500-5,000 units once you have velocity. Don't skip the learning phase by ordering 10,000 units before you know what's working.
For DTC brands, pair your launch with content that targets supplement-related search queries (like this article!) and influencer outreach in your niche.
If you're serious about launching a liquid supplement brand in 2025, the best first step is a conversation with a manufacturer who knows what they're doing. Contact Nutrilab here for a free consultation and quote - no commitment, just a real conversation about your project.
