Top 10 Zeaxanthin Suppliers, Manufacturers, Wholesalers, and Traders in Spain

1. Mediterranean Extracts S.A. (Barcelona)

Tucked away in the heart of Barcelona's industrial district, Mediterranean Extracts S.A. has been a cornerstone of Spain's natural extracts industry since 1998. What sets them apart? Their unwavering commitment to local sourcing. Unlike many suppliers who import raw materials from abroad, Mediterranean Extracts partners with over 50 family-owned farms in Andalusia and Murcia to grow marigold flowers—nature's richest source of zeaxanthin. This "farm-to-factory" approach not only ensures freshness but also supports local agriculture, a point that resonates deeply with eco-conscious brands.

Their product lineup includes zeaxanthin powder in concentrations ranging from 5% to 20%, as well as pre-mixed lutein-zeaxanthin blends (a popular choice for eye health supplements, since the two carotenoids work synergistically). Every batch undergoes rigorous testing in their in-house lab, where technicians check for purity, heavy metals, and microbial contamination. "We believe transparency is non-negotiable," says Maria Lopez, the company's quality control manager. "Our clients get a full certificate of analysis with every order, so they know exactly what they're putting into their products."

Certifications? They've got them: ISO 9001 for quality management, GMP for manufacturing practices, and EU Organic certification for their premium organic line. And if you're worried about scalability? Mediterranean Extracts can handle orders from 1kg to 500kg per month, with lead times as short as 5 business days for stock items. Small wonder they're a go-to for both local startups and international brands like a well-known French skincare company that uses their zeaxanthin in anti-aging serums.

2. GreenWave Nutraceuticals (Madrid)

If you're in the pharmaceutical or high-end supplement space, GreenWave Nutraceuticals in Madrid should be on your radar. Founded in 2005 by a team of biochemists, this company specializes in pharmaceutical-grade zeaxanthin that meets the strictest standards—think 99.9% purity and ultra-low heavy metal levels (below 0.1ppm). Their state-of-the-art facility in Madrid's science park is equipped with cold extraction technology, which preserves the integrity of the zeaxanthin molecule better than traditional heat-based methods. "Stability is key," explains Dr. Javier Ruiz, GreenWave's head of R&D. "Our zeaxanthin has a shelf life of 36 months when stored properly, which is 12 months longer than the industry average."

While they're best known for bulk powder, GreenWave also offers custom encapsulation services—a lifesaver for small brands that don't have the equipment to turn powder into pills. Need vegan capsules? No problem. Want to add vitamin E as an antioxidant stabilizer? They've got you covered. Their client list includes pharmacies across Spain, as well as supplement brands in Germany and Italy that require EU pharmaceutical certification. And yes, they're certified Kosher and Halal, making them a versatile choice for global markets.

What about sustainability? GreenWave is proud of their carbon-neutral manufacturing process, which uses solar panels to power 60% of their facility and recycles 95% of their water. "We think of ourselves as not just a supplier, but a partner in our clients' success," says CEO Elena Mendez. "If you're launching a new product, our team will even help with formulation advice—no extra charge. After all, your success is our success."

3. BioNaturals Valencia (Valencia)

For brands that prioritize "organic" and "sustainable" above all else, BioNaturals Valencia is a breath of fresh air. This family-run business, started by Juan and Sofia Gomez in 2010, has built its reputation on two pillars: 100% organic zeaxanthin and a zero-waste manufacturing process. Let's break that down. Their marigold flowers are grown on certified organic farms in Valencia, where pesticides and synthetic fertilizers are strictly forbidden. Once harvested, every part of the flower is used: the petals are pressed for zeaxanthin, the stems are turned into compost for the farms, and even the water from extraction is filtered and reused to irrigate the fields.

The result? A zeaxanthin extract that's not only organic (certified by both the EU and USDA) but also has a carbon footprint 40% lower than the industry average. Their flagship product is a 10% organic zeaxanthin powder, but they also offer softgel capsules for brands that want a ready-to-sell supplement. "We started BioNaturals because we saw a gap in the market for truly sustainable extracts," Sofia Gomez recalls. "Too many companies greenwash their products—we wanted to walk the walk."

Quality isn't an afterthought here, either. BioNaturals is Non-GMO Project Verified, and their lab uses HPLC (high-performance liquid chromatography) to test for zeaxanthin content, ensuring that what's on the label matches what's in the bottle. They're also a hit with cosmetic brands: a popular Spanish natural skincare line uses their organic zeaxanthin in a brightening serum, marketing it as "nature's own glow booster."

Orders start at 500g, and while their prices are slightly higher than non-organic options, clients say the premium is worth it for the sustainability story and purity. "Our customers aren't just buying an ingredient—they're buying a mission," Juan Gomez adds with a smile.

4. Iberian Health Ingredients (Seville)

If speed and scalability are your top priorities, look no further than Iberian Health Ingredients in Seville. Founded in 2005, this wholesaler and manufacturer prides itself on being "Spain's fastest zeaxanthin supplier," with a warehouse that stocks over 10 tons of finished product at any given time. Need 100kg of 20% zeaxanthin powder by the end of the week? They can ship it tomorrow. "We know that in the supplement industry, delays can cost businesses money," says operations manager Carlos Ruiz. "That's why we invested in a state-of-the-art logistics system—we never want to say 'no' to a rush order."

But don't mistake speed for skimping on quality. Iberian Health Ingredients holds ISO 14001 (for environmental management) and GMP certifications, and their zeaxanthin is tested for purity by an independent lab in Madrid. Their product range includes standard bulk powder (5-30% concentration), as well as water-soluble zeaxanthin—a game-changer for beverage brands, since traditional zeaxanthin doesn't dissolve in water. "We developed our water-soluble formula in 2018 after a client asked for a zeaxanthin they could add to energy drinks," Carlos explains. "Now it's one of our bestsellers, used in everything from sports drinks to functional waters."

They also cater to international markets, with experience exporting to over 20 countries, including France, Portugal, and even as far as Australia. Their FSSAI certification (India's food safety standard) makes them a popular choice for clients in Asia, too. And with prices that are 15-20% lower than some competitors (thanks to their large scale), they're a favorite among budget-conscious brands that don't want to compromise on quality.

5. Nature's Extracts Barcelona (Barcelona)

Traceability is the name of the game at Nature's Extracts Barcelona. This mid-sized supplier has built its brand around one promise: "You can track your zeaxanthin from seed to shelf." Here's how it works: every batch of marigold seeds is assigned a unique QR code. Scan it, and you'll see where the seeds were grown (they work with farms in Catalonia and Aragon), when they were planted, how they were harvested, and even the name of the farmer. Once the flowers are processed, the QR code is updated with extraction dates, lab results, and shipping info. "We started this because we were tired of hearing horror stories about suppliers cutting corners with cheap, untraceable ingredients," says founder Anna Martinez. "Our clients deserve to know exactly what they're putting into their products—and who they're supporting."

Their zeaxanthin powder (available in 5-25% concentrations) is 100% natural, with no synthetic additives or preservatives. They also offer lutein-zeaxanthin blends, which are a hit with supplement brands targeting eye health—after all, lutein and zeaxanthin are often paired for their combined benefits. Nature's Extracts is Ecocert certified (for organic products) and Halal certified, making them a versatile choice for diverse markets.

What really makes them stand out, though, is their customer service. New clients get a dedicated account manager who walks them through the ordering process, answers questions about formulations, and even provides samples for testing. "We treat every client like a partner," Anna says. "Whether you're ordering 1kg or 1000kg, you'll get the same level of attention." It's this personal touch that has earned them repeat business from brands like a Spanish pharmacy chain that includes their zeaxanthin in its house-brand multivitamins.

6. Madrid Nutra Ingredients (Madrid)

While many zeaxanthin suppliers focus on supplements, Madrid Nutra Ingredients has carved out a niche in the cosmetic industry. This specialized manufacturer creates zeaxanthin extracts tailored for skincare and haircare products, with formulations designed to boost stability and absorption in topical applications. "Zeaxanthin is a powerful antioxidant, but it's tricky to use in cosmetics because it can degrade quickly when exposed to light and air," explains cosmetic chemist Laura Diaz, who leads their R&D team. "Our microencapsulated zeaxanthin solves that problem—it's protected by a plant-based shell that breaks down slowly, releasing the active ingredient over time."

Their star product is a 1% zeaxanthin serum base, which cosmetic brands can customize with other ingredients like hyaluronic acid or vitamin C. They also offer a powdered form (5-10% concentration) for creams, lotions, and even hair masks (zeaxanthin's antioxidant properties are said to help protect hair from UV damage). Madrid Nutra Ingredients holds COSMOS certification (the gold standard for natural cosmetics) and ECOCERT, ensuring their products meet the strictest standards for natural and organic beauty.

They're also happy to work on custom projects: a luxury Spanish skincare brand recently partnered with them to create a zeaxanthin-infused eye cream, and they're currently developing a water-based zeaxanthin extract for a major European sunscreen company. "The cosmetic industry is always evolving, and we pride ourselves on staying ahead of the curve," Laura adds. "If a client has an idea, we'll work with them to make it a reality."

7. Valencia Bioactives (Valencia)

For brands that demand the highest purity, Valencia Bioactives is the supplier of choice. This manufacturer specializes in high-concentration zeaxanthin, with powders available in strengths up to 40%—among the highest in Spain. How do they achieve such potency? Their proprietary extraction process, which uses supercritical CO2 (a solvent-free method) to isolate zeaxanthin from marigold petals. "Supercritical extraction is more expensive, but it preserves the integrity of the molecule and results in a purer product," explains chief scientist Dr. Miguel Torres. "For pharmaceutical companies or research labs, that level of purity is non-negotiable."

Valencia Bioactives is FDA registered, making their zeaxanthin suitable for use in pharmaceutical products, and they're also ISO 22000 certified for food safety. Their lab is equipped with advanced testing equipment, including mass spectrometry, to ensure every batch meets their strict specs for heavy metals, pesticides, and microbial counts. "We once rejected a entire shipment of marigold flowers because the pesticide levels were 0.01ppm above our limit," Dr. Torres recalls. "Quality isn't something we compromise on."

While their high-purity powders are their claim to fame, they also offer a lutein-zeaxanthin complex designed for eye health supplements, with a 5:1 lutein-to-zeaxanthin ratio (the same ratio found naturally in the macula of the eye). Clients include universities conducting zeaxanthin research, as well as pharmaceutical companies developing prescription eye health medications. Yes, their prices are on the higher side, but for brands that need the best of the best, Valencia Bioactives delivers.

8. Barcelona Bulk Extracts (Barcelona)

As the name suggests, Barcelona Bulk Extracts is all about large-scale orders. This wholesaler, founded in 2010, focuses on supplying bulk zeaxanthin powder (and other natural extracts) to manufacturers, distributors, and large supplement brands across Europe. Their sweet spot? Orders of 500kg or more, though they'll take smaller orders for regular clients. "We built our business on the idea that bigger shouldn't mean worse," says sales director Pablo Sanchez. "Even with large orders, we never sacrifice quality or customer service."

Their zeaxanthin powder comes in concentrations from 5% to 30%, and they source raw materials from both Spanish farms and trusted international suppliers (including organic marigold from India and China). Every batch is tested by an independent lab in Barcelona, and they provide a full COA (certificate of analysis) with every shipment. They also offer private labeling for clients who want to sell bulk supplements under their own brand—a service that includes bottle design, labeling, and packaging.

Certifications include GMP, ISO 13485 (for medical devices), and Halal, making them a versatile choice for diverse markets. And with a warehouse that spans 10,000 square meters, they can store large quantities for clients who want to lock in prices or avoid supply chain delays. "We've had clients tell us we saved their business during the 2022 supply chain crisis because we had stock when others didn't," Pablo adds. For brands that need reliability and scale, Barcelona Bulk Extracts delivers.

9. Seville Natural Ingredients (Seville)

Seville Natural Ingredients is on a mission to make sustainable zeaxanthin accessible to everyone. Founded in 2015 by a group of environmental scientists, this supplier combines eco-friendly practices with affordable pricing—no small feat in the natural extracts world. Their marigold flowers are grown on sustainable farms in Andalusia that use drip irrigation to conserve water, and their extraction process runs on renewable energy (solar and wind power). Even their packaging is eco-friendly: bulk orders come in compostable bags, and smaller orders use recycled cardboard boxes.

Their product lineup includes organic zeaxanthin powder (5-20% concentration), as well as lutein-zeaxanthin blends tailored for functional foods. "We work with a lot of cereal and yogurt brands that want to add zeaxanthin as a 'natural nutrient boost,'" explains sustainability director Lucia Fernandez. "Our water-soluble zeaxanthin is perfect for that—it mixes easily and doesn't change the taste or texture of the food."

Certifications include EU Organic, USDA Organic, and Non-GMO Project Verified, and they're currently working on getting B Corp certification (a rigorous standard for social and environmental performance). They also donate 5% of profits to reforestation projects in Spain, a commitment that resonates with mission-driven brands. "We believe that doing good and doing well shouldn't be mutually exclusive," Lucia says. "Our clients get a great product, and they get to feel good about where it came from."

10. Spanish Extract Traders (Madrid)

Last but not least, Spanish Extract Traders is the go-to for brands that want access to global zeaxanthin varieties. While they do source from Spanish farms, they also import high-quality zeaxanthin from around the world—including algae-based zeaxanthin from Japan (a vegan alternative to marigold), organic marigold from India, and even rare saffron-derived zeaxanthin for luxury cosmetic brands. "We see ourselves as a bridge between global suppliers and Spanish businesses," says founder David Martin. "Why limit yourself to what's grown locally when there are amazing ingredients worldwide?"

Their product range is the most diverse on this list, with everything from bulk powder to pre-formulated supplements, and they specialize in hard-to-find extracts. Need 1kg of 98% pure synthetic zeaxanthin for research? They can get it. Want a custom blend of zeaxanthin, astaxanthin, and beta-carotene for a sports supplement? They'll create it. "Our clients come to us with unique requests, and we love the challenge," David adds.

Certifications include ISO 9001, FSSAI, and GMP, and they have experience navigating international regulations, including FDA requirements for the U.S. market. They also offer consulting services for brands new to the extract world, helping with everything from ingredient selection to regulatory compliance. "We don't just sell ingredients—we partner with our clients to help them succeed," David says. For brands that value variety and expertise, Spanish Extract Traders is a top pick.
