Explore our export-ready, GMP-certified bulk botanical extracts engineered for optimal stability, high intestinal permeability, and precise clinical efficacy. Designed specifically for contract manufacturers, pharmaceutical compounders, and dietary supplement brands in San Francisco and North America.
Zeaxanthin (3R,3'R-dihydroxy-β-carotene; CAS Number: 144-68-3) is an essential oxygenated xanthophyll carotenoid naturally concentrated in the central fovea of the human retina. As a principal structural pigment forming the macular protective barrier against high-energy short-wave blue light (400–470 nm), high-purity Zeaxanthin has evolved from a basic dietary supplement into a targeted pharmaceutical and neuro-nutraceutical ingredient.
For research-driven formulators and contract manufacturing organizations (CMOs) operating within San Francisco and the wider Bay Area biotech corridor, procuring consistent, high-purity OEM Zeaxanthin powder requires a granular understanding of stereoisomeric composition, matrix microencapsulated stabilization, and intestinal micellarization physics.
Our industrial extraction isolates raw xanthophylls primarily from Tagetes erecta L. oleoresin, converting lutein esters via high-yield enzymatic or chemical isomerism into pure (3R,3'R)-Zeaxanthin. Every production lot undergoes rigorous High-Performance Liquid Chromatography (HPLC) coupled with Chiral Column Phase verification to guarantee zero contamination from non-functional degradation isomers.
Unprocessed lipophilic crystalline Zeaxanthin suffers from poor aqueous solubility (<0.01 mg/mL) and extreme susceptibility to photo-oxidation. Our custom OEM solutions utilize advanced spray-drying spray-chilling microencapsulation using matrix carriers such as modified starch, gum arabic, or liposomal phospholipids to produce 5%, 10%, and 20% Cold-Water Dispersible (CWD) beadlets.
Meeting the ultra-clean standards enforced by Northern California consumers, our facilities employ dense-phase Supercritical Fluid CO2 Extraction. This eliminates neurotoxic organic residual solvents like hexane, acetone, or ethylene dichloride, yielding a clean-label product compliant with California Proposition 65 limits for heavy metals and solvent residues.
San Francisco, South San Francisco (the birthplace of biotechnology), and the greater Silicon Valley region represent one of the world's highest concentrations of bio-hackers, software engineers, clinical researchers, and health-conscious professionals. This unique demographic landscape dictates specific product innovation trends in the local functional food, nutricosmetics, and dietary supplement sectors.
With tech workers spending an average of 10 to 14 hours daily in front of high-luminance OLED and LED displays, the demand for ocular endurance supplements in the Bay Area has surged by 34% year-over-year. Custom OEM Zeaxanthin powder is widely formulated alongside Lutein, Astaxanthin, and Bilberry extracts into targeted "Screen Time Protection" capsules and gummies. Zeaxanthin selectively quenches singlet oxygen species ($^1O_2$) and absorbs blue spectrum radiation, reducing visual fatigue, glare sensitivity, and contrast deterioration.
Beyond macular protection, cutting-edge neurobiology research from Northern California academic centers highlights Zeaxanthin's role in neural membrane stability and cerebral blood flow enhancement. Localized startups in San Francisco's Mission District and SoMa are incorporating microencapsulated CWD Zeaxanthin powder into instant ready-to-mix nootropic powders, plant-based brain fogs, and functional coffee creamers designed to improve processing speed and executive cognitive performance.
San Francisco's eco-conscious consumer base heavily favors clean-label, plant-derived skin health products. Zeaxanthin acts as an systemic oral photoprotectant by scavenging free radicals generated by solar UV radiation within skin dermal layers. Regional custom formulations combine 95% pure Zeaxanthin extract with Liposomal Glutathione and Hyaluronic Acid to create premium oral cosmetic capsules targeting photo-aging prevention and hyperpigmentation control.

As a specialized botanical extraction manufacturer operating since 2014, our production operations combine decades of phytochemical expertise with modern analytical validation. We do not act as a mere broker; we control the full chain of manufacturing—from contracted raw botanical growing fields to high-vacuum distillation, column chromatographic isolation, and cleanroom packaging.
Every batch of raw botanical input originates from our dedicated, contracted planting farms. We maintain meticulous agricultural logs recording soil composition, non-GMO seed origin, harvest dates, and pesticide application histories, enabling 100% full-chain traceability from seed to final delivered drum in San Francisco.
Our quality control laboratories are equipped with state-of-the-art Waters HPLC instruments, UV-Vis spectrophotometers, Agilent GC-MS systems for residual solvent screening, and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for ultra-trace heavy metal detection (PDB, As, Cd, Hg).
Our manufacturing plant operates under strict ISO 22000, HACCP, and cGMP quality management systems. Furthermore, our raw materials carry comprehensive international certifications including KOSHER, HALAL, and USDA Organic compliant verification packages ready for immediate regulatory filing.
We offer comprehensive contract manufacturing support for San Francisco brand owners, including custom particle sizing (from 40 mesh to micro-fine 200 mesh), customized bulk density tuning, carrier swaps (maltodextrin, rice hull fiber, acacia gum), and proprietary premix blending.
