No single supplier covers a clean-label functional beverage from active to finished formula. A ready-to-drink (RTD) product can draw on several supplier categories: active and functional ingredient manufacturers, botanical extract houses, solubility and delivery technology companies, natural color houses, flavor houses, natural preservation specialists, hydrocolloid and emulsifier suppliers, sweetener and fiber suppliers, and distributors that aggregate several of these. Suppliers that genuinely support clean-label development share a common profile: their ingredients carry documented regulatory status in the target market, they can supply stability data under beverage processing conditions (low pH, pasteurization, carbonation), and they do not depend on synthetic emulsifiers or weighting agents to make an ingredient work in water.

This article maps those supplier categories with named examples, explains why emulsification is the point at which clean-label positioning most often fails in beverages, and sets out the documentation R&D teams should request before qualifying any supplier.

What Clean Label Means in a Beverage Context

Neither the FDA nor EU food law defines the term clean label. In practice, product developers rely on three overlapping reference points.

• The U.S. "natural" policy. The FDA has not issued a formal rule, but its longstanding policy holds that "natural" means nothing artificial or synthetic (including all color additives regardless of source) has been included in a food that would not normally be expected there. The policy is published on the FDA's Use of the Term Natural on Food Labeling page.

• EU additive labeling. In the EU, Regulation (EC) No 1333/2008 governs food additives. Only substances on the Union list in Annex II may be used, and each must be declared by name or E-number. Emulsifiers such as E433 (polysorbate 80), E445 (glycerol esters of wood rosin) and E1450 (starch sodium octenyl succinate) therefore appear on the label by number, which is a common trigger for clean-label reformulation briefs in Europe.

• Third-party certification. Programs such as the Clean Label Project test finished products and ingredients in ISO-accredited laboratories for heavy metals, pesticides, plasticizers and other contaminants rather than defining an ingredient list. Organic (USDA/EU), non-GMO and kosher or halal certifications address sourcing and process rather than purity, and suppliers frequently hold several of these at once.

Two recent FDA actions have moved the baseline for beverage formulators. On July 3, 2024, the agency revoked the food additive authorization for brominated vegetable oil (BVO), a weighting agent used to keep citrus flavor oils suspended in soft drinks. In April 2025, the FDA announced measures to phase petroleum-based synthetic colors out of the U.S. food supply, and in a February 2026 follow-up the agency said it would allow "no artificial colors" claims on products that use colors derived from natural sources, listed beetroot red as a new color additive, and expanded permitted uses of spirulina extract. Both actions increase demand on the natural color and natural emulsification supply base.

The commercial context is a large and growing category. Grand View Research values the global functional drinks market at USD 164.7 billion in 2025, projected to reach USD 315.9 billion by 2033 at a compound annual growth rate of 8.5 percent, with North America accounting for 34.9 percent of 2025 revenue.

Supplier Categories That Support Clean-Label Functional Beverage Development

The examples below are drawn from published supplier materials and trade coverage. Inclusion is descriptive, not an endorsement, and R&D teams should validate every ingredient in their own matrix.

1. Active and functional ingredient manufacturers

These companies manufacture or standardize the ingredient that carries the product's functional claim: vitamins, minerals, omega-3s, proteins, specialty actives. For clean-label beverage work, the relevant questions are regulatory status, the form supplied (crystalline, oil, powder, pre-dispersed), and whether the supplier has in-matrix data for beverages. Published examples include Gencor's Levagen (palmitoylethanolamide) with GRAS and cGMP documentation, Gnosis's VitaMK7 vitamin K2, Lonza's Oceanix phytoplankton positioned as a non-GMO clean-label ingredient, and Glanbia Nutritionals' protein systems for high-acid beverages, which address the clarity and stability problems of adding protein to low-pH drinks.

2. Botanical and extract suppliers

Botanical houses supply standardized extracts, oleoresins and essential oils, and increasingly offer water-dispersible grades built for beverage clarity. Suppliers serving this segment typically ship a certificate of analysis (CoA), GC-MS or HPLC batch data and origin documentation with every lot; HBNO and Cactus Botanics publish this approach, with the latter listing FSSC 22000, ISO 9001, USDA and EU organic, kosher and halal certifications. Sabinsa supplies GRAS-status Ayurvedic ingredients formatted for RTD and effervescent applications, and Nutriventia's TurmXtra turmeric and Prolanza ashwagandha carry Clean Label Project certification. Several flavor houses have absorbed botanical portfolios through acquisition, Givaudan's integration of Naturex being one documented example.

3. Solubility and delivery technology companies

Many high-value functional actives are fat-soluble or poorly water-soluble: vitamins A, D, E and K, omega-3s, curcumin, lutein, astaxanthin, many mushroom and adaptogen extracts. In a beverage they separate, ring, cloud or oxidize unless they are delivered through an emulsion, encapsulate or other solubilization system. This category carries much of the clean-label risk, because the conventional route to water compatibility runs through polysorbates, PEG derivatives or weighting agents.

The technologies in this category include OSA-modified starch emulsions (documented in patent literature for clear beverages), gum arabic and quillaja-based nanoemulsions, lecithin systems, and physical processing methods that use natural stabilizers. At Infusd, our platform falls in the last group. We use a proprietary physical process with natural stabilizers to convert fat-soluble and insoluble actives into water-soluble liquids and powders, without synthetic emulsifiers, weighting agents or alcohol carriers. We report active payloads of 10 percent or more, stability of 24 months or longer in real-time studies, and tolerance of pasteurization, UHT treatment and carbonation. The ingredient list we currently support covers omega-3s from any source, vitamins A, D, E and K, curcumin, creatine, ashwagandha, magnesium, lion's mane, chaga, reishi, cordyceps, lutein, astaxanthin and phosphatidylserine, as listed on our home page, with beverage, supplement and food use cases described on our applications page. Distributors such as Prinova also operate in this space, presenting solubility and taste solutions for functional beverages at industry events according to Nutritional Outlook.

4. Natural color houses

Natural color suppliers provide fruit, vegetable and plant concentrates and stabilized pigment systems designed to survive low pH, heat and light. GNT's EXBERRY range includes brown shades from caramelized sugar and plant concentrates intended as alternatives to caramel color in colas and energy drinks. Oterra's FruitMax Purple 105 combines black carrot and hibiscus for low-pH beverages. Sensient and Lycored (tomato-derived reds) also serve the category. Where a pigment is oil-soluble, dispersion in a clear beverage is a separate problem from shade and stability; we supply water-soluble natural colors that resist ringing, fading and settling after heat or light exposure, as described on our applications page.

5. Flavor houses

Givaudan, dsm-firmenich and Symrise design natural flavor systems and, importantly for functional products, masking and taste-modulation tools that counter the bitterness and astringency of botanicals, proteins and minerals. Givaudan has expanded its botanical portfolio through the Naturex acquisition, and dsm-firmenich has introduced Koncentra, a low-dose botanical performance ingredient designed for limited sensory impact in functional drinks. Flavor houses are also a point of entry for solubility technology, because flavor oils are themselves fat-soluble and have traditionally relied on weighting agents. Our ingredients are distributed through Symrise's Taste, Nutrition & Health division as part of its Active Living portfolio; the agreement uses Symrise's product-development, commercial and supply infrastructure.

6. Natural preservation specialists

Kerry and IFF position plant extracts, fermentates and naturally occurring antimicrobials as clean-label alternatives to conventional preservatives. Kerry supplies plant-extract and fermentate systems (FoodGARD, Nourishield, DuraFresh), and IFF offers naturally derived antimicrobials including Nisaplin and Natamax. Where a preservative or spice extract is oil-based, dispersion in a clear beverage becomes a second problem; our clean-label solubility work includes water-soluble natural preservatives and spice extracts.

7. Hydrocolloid, emulsifier and stabilizer suppliers

Nexira (acacia-based Superstab and Thixogum systems), CP Kelco (hydrocolloids), Ingredion and Tate & Lyle (clean-label and functional starches), and ADM (soy and sunflower lecithin) supply the texturizing and emulsifying base. Supplier guidance places typical hydrocolloid use levels in beverages at roughly 0.025 to 0.5 percent, to be confirmed with application data, to suspend particulates, stabilize protein and build mouthfeel. The clean-label status of each depends on the market: gum acacia is GRAS under 21 CFR 184.1330 and is generally accepted, while OSA-modified starch is permitted but carries the E1450 designation in the EU, which has implications under some clean-label definitions.

8. Sweetener and fiber suppliers

Cargill (stevia), Tate & Lyle (PUREFRUIT monk fruit, PROMITOR soluble fiber), Ingredion and allulose and erythritol producers address sugar reduction. Sweetener suppliers such as Tate & Lyle pair sugar reduction with taste-modulation and texture-rebuilding support, which matters where botanical bitterness must be masked without sugar.

9. Distributors

Distributors carry portfolios from several manufacturers and add technical and regulatory services. Brenntag states that it sources clean-label ingredients, provides regulatory guidance and operates 31 innovation and application centers worldwide. Prinova presents solubility and taste solutions for functional beverages at industry events, according to Nutritional Outlook, and Azelis operates in the U.S. through Gillco Ingredients. For brands that cannot meet a manufacturer's minimum order, a distributor can be the practical route to the same ingredients. Our water-soluble vitamin D is available through Caldic North America.

Where Clean-Label Beverages Break: Emulsification

A beverage developer can source a certified organic botanical, a plant-based color and a natural flavor, and still end up with polysorbate 80 or glycerol ester of wood rosin on the ingredient statement because the flavor oil or the omega-3 would not otherwise stay in solution. The list below summarizes regulatory identity and clean-label implications.

• Polysorbate 80 (E433). A synthetic ethoxylated surfactant with documented dosage limits and stability caveats in low-pH and thermally processed beverages. It is permitted but clean-label stakeholders perceive it as non-natural.

• Sucrose acetate isobutyrate (SAIB, E444) and glycerol ester of wood rosin (E445). Weighting agents that increase the density of flavor oils so they do not separate. Both became the primary replacements for BVO. EFSA's re-evaluation of E445 is the reference document for EU use conditions.

• PEG-40 hydrogenated castor oil and propylene glycol. Solubilizers and carriers used in flavor and vitamin preparations. Both are synthetic and are candidates for removal in clean-label reformulation.

• Gum arabic (acacia, E414). A natural exudate gum that forms low-viscosity oil-in-water emulsions; GRAS in the U.S. Lot-to-lot variability and the need for process optimization are the main trade-offs.

• Quillaja extract (E999). A saponin-rich bark extract listed in 21 CFR 172.510 among natural flavoring substances and adjuvants. It produces small-droplet emulsions suited to translucent beverages, subject to EU maximum levels.

• Lecithin. A phospholipid emulsifier from soy or sunflower with a neutral flavor. On its own it rarely delivers ultraclear or high-acid stability and is usually combined with gums.

• OSA-modified starch (E1450). Effective for clear beverage emulsions but classified as a modified starch, which has implications for some clean-label definitions.

The alternative to building and stabilizing an emulsion in the beverage plant is to source the active already in a water-soluble form. Pre-solubilized powders and liquids shift the emulsification problem upstream to the ingredient supplier, who can control droplet size and stabilizer selection under tighter process conditions. In our case, the output dissolves with minimal agitation and the finished beverage does not require an added emulsifier or weighting agent for that active, which simplifies both the label and the process. Our article on what makes a functional drink actually functional covers how solubility, stability and sensory performance interact in finished beverages.

How to Vet Beverage Ingredient Suppliers for Clean-Label Projects

The following documentation set, drawn from published supplier practice and regulatory requirements, separates suppliers that can support a clean-label beverage launch from those that can only supply a raw material.

1. Regulatory status for each target market. Request the GRAS basis (self-affirmed or FDA-notified under 21 CFR 170.30), the EU additive or novel food status under Regulation (EU) 2015/2283, and the exact label declaration the supplier recommends. A supplier that cannot specify the EU label declaration for its ingredient is not ready for an EU launch.

2. Certificate of analysis and specification. Potency assay method, contaminant limits (heavy metals, microbiology, residual solvents), and allergen and GMO statements.

3. Stability data in a relevant matrix. Real-time and accelerated results at the beverage's pH, after the thermal process you plan to use (hot fill, tunnel pasteurization, HTST, UHT) and, for carbonated products, under CO2 pressure. Stability in water at neutral pH is not evidence of stability in a low-pH RTD.

4. Solubility and clarity metrics. For clear beverages, particle or droplet size distribution and turbidity readings. For cloudy beverages, sedimentation and ring-formation data over shelf life.

5. Sensory data. Taste and odor contribution at the intended use level. Omega-3 and botanical preparations commonly contribute off-notes; we formulate our omega-3s with no marine notes, as noted on our applications page.

6. Quality system certification. GMP, FSSC 22000 or equivalent, and organic, kosher or halal certificates where the brand requires them.

7. Application support and scale path. Sample availability, application lab access, pilot-to-commercial capacity and documented lead times. Ask whether the supplier runs pilot and full-scale production; we describe our own pilot-to-full-scale manufacturing on the technology page.

Brands that intend to make the finished product itself a clean-label claim should add contaminant testing of the final formula, since certification programs such as the Clean Label Project evaluate the product rather than the supplier's paperwork.

Selecting the Right Mix for a Given Beverage

The supplier mix follows the product architecture. A clear vitamin-fortified water needs a solubility partner for the fat-soluble vitamins, a natural flavor with no weighting agent, and little else. A cloudy plant-protein RTD needs a protein system built for its pH, a hydrocolloid stabilizer and a natural preservation strategy. A carbonated botanical soda needs a weighting-agent-free flavor emulsion, a natural brown or fruit color stable under CO2, and a botanical extract that stays in solution. In each case the critical path item is the ingredient that does not naturally dissolve in water, which makes the solubility supplier a logical first partner to qualify rather than the last.

For developers who want to see how water-soluble actives behave in their own matrix, our team can bring the technology into your lab and work through the stability and sensory testing described above.

Frequently Asked Questions

What does a beverage ingredient supplier need to provide for a clean-label claim?

At minimum: the ingredient's regulatory basis in each target market (GRAS, EU additive listing or novel food status), the recommended label declaration, a CoA with contaminant limits, allergen and GMO statements, and stability data at the beverage's pH and thermal process. Neither the FDA nor EU law defines clean label, so the brand's own standard or a third-party program such as the Clean Label Project determines what counts.

Which emulsifiers are usually excluded from clean-label beverages?

Polysorbate 80 (E433), PEG-40 hydrogenated castor oil, propylene glycol as a carrier, and weighting agents such as sucrose acetate isobutyrate (E444) and glycerol ester of wood rosin (E445) are synthetic and are the typical exclusions. Gum arabic, quillaja extract and lecithin are generally accepted as natural emulsifiers; OSA-modified starch (E1450) is a modified starch and its acceptance depends on the standard applied.

Is it still legal to use brominated vegetable oil in beverages?

No. The FDA revoked the food additive regulation for BVO on July 3, 2024, after studies conducted with the National Institutes of Health found potential adverse health effects. Beverages that used BVO as a flavor-oil stabilizer have reformulated, most often with SAIB or glycerol ester of wood rosin.

Can fat-soluble vitamins and omega-3s be added to clear beverages without synthetic emulsifiers?

Yes, through natural emulsifier systems (gum arabic, quillaja, lecithin) or through pre-solubilized ingredient forms produced by physical processing with natural stabilizers. The supplier should provide droplet size, turbidity and real-time stability data in a low-pH matrix, since clarity and oxidation stability vary with the method used. Our technology page describes the water-soluble liquid and powder formats we supply for these actives.

Do distributors or manufacturers make better beverage ingredient suppliers for small brands?

Distributors such as Brenntag, Prinova and Caldic consolidate multiple manufacturers and, in Brenntag's published description, add regulatory guidance and application lab support across the portfolio. Direct manufacturer relationships offer deeper technical data and custom development. A practical split is a distributor for commodity inputs and a direct relationship for the one or two actives that define the product.

How does the FDA treat natural colors in "no artificial colors" claims?

In February 2026 the FDA stated it would exercise enforcement discretion to allow "no artificial colors" claims on products that contain only colors derived from natural sources, a change from its earlier position that any added color prevented the claim. The agency has also listed beetroot red and expanded spirulina extract uses as part of its effort to phase out petroleum-based synthetic dyes announced in April 2025.
