Introduction
Marigold (Tagetes erecta L.), a cherished medicinal and ornamental herb native to Central and South America, has been prized for centuries in traditional practices for supporting ocular and skin health. Modern scientific research has validated that its core active constituent—Marigold Extract (standardized to 20% Lutein)—plays a crucial role in promoting eye health by filtering harmful blue light and protecting retinal cells. It is also widely acknowledged for its potent antioxidant properties that support skin integrity and combat oxidative stress, making it a trusted ingredient in vision support and skincare supplements.

Part 1: What is Marigold Extract?

· Source Plant: Derived from the marigold plant, Tagetes erecta L. (also known as African marigold), of the Asteraceae (aster/daisy) family. Native to Central and South America, it is widely cultivated in tropical and subtropical regions worldwide—including India, China, Mexico, and parts of Southeast Asia—primarily for medicinal, ornamental, and industrial use, with large-scale cultivation optimized for high lutein content.

· Extracted From: Flower and capitula.

· Active Components: The primary active compound is lutein (a xanthophyll carotenoid), the key marker standardized to 20% in the extract. It also contains synergistic bioactive substances such as zeaxanthin (a structurally related xanthophyll), carotenes, and phenolic acids, which work in tandem to enhance its antioxidant and ocular health-supporting effects.

· Analysis Report: We provide a detailed Certificate of Analysis for each batch, ensuring lutein content, heavy metals, pesticide residues, and microbiological limits comply with international pharmacopoeia and food standards.

Part 2: Key Health Benefits and Mechanisms of Action
The health benefits of Marigold Extract 20% lutein are backed by extensive scientific research and traditional use::

· Supports Ocular Health: Its key active compound lutein (a xanthophyll carotenoid) accumulates in the macula and retina, acting as a natural "blue light filter" to protect retinal cells from oxidative damage caused by high-energy light. This helps maintain visual acuity, support macular health, and reduce the risk of age-related eye concerns, without interfering with normal visual function.

· Enhances Antioxidant Defense: Lutein, along with synergistic zeaxanthin and carotenes, exerts potent antioxidant activity to neutralize free radicals in ocular and skin tissues. By reducing oxidative stress, it helps protect cells from premature aging, supporting long-term tissue health and resilience against environmental stressors.

· Promotes Skin Integrity: The carotenoids and phenolic acids in the extract contribute to skin health by supporting the skin’s natural barrier function and mitigating UV-induced damage. It helps improve skin hydration, reduce the appearance of fine lines caused by oxidative stress, and enhance skin radiance, making it a valuable ingredient for topical and oral skincare support.

· Supports Visual Comfort: Clinical research suggests lutein may alleviate eye strain and fatigue associated with prolonged screen time (digital eye strain) by reducing retinal light exposure and supporting tear film stability. It helps ease symptoms such as dryness, blurred vision, and eye tiredness, promoting overall visual comfort in daily life.

Also incorporated into eye care formulations (eye creams, under-eye masks) to support delicate eye area health.

• Nutraceutical & Wellness Products: Featured in specialized wellness blends, powdered supplements, and on-the-go nutrition sachets designed for holistic health, leveraging its synergistic effects with other antioxidant-rich ingredients (e.g., vitamin C, Astaxanthin, or resveratrol) to enhance overall tissue protection and wellness.

Part 4: How to Choose a High-Quality Marigold Extract
To ensure efficacy, consider the following when selecting a supplier:

· Standardization & Bioactivity: Always select a product standardized for lutein content (targeting 20% as the core specification). This ensures consistent bioactivity and reliable efficacy in supporting hormonal balance.

· Comprehensive Testing: Trusted suppliers provide third-party COAs (Certificate of Analysis) covering critical indicators: pesticide residues (compliant with EU MRL standards), heavy metals (Pb, Cd, Hg ≤1 ppm), microbial limits (total aerobic bacteria ≤10³ CFU/g), and absence of harmful contaminants like aflatoxins. This guarantees a safe, pure extract.

· Regulatory Compliance: Our products adhere to global regulatory requirements, including USP/EP standards for botanical extracts, EU Dietary Supplement Directive, and FDA guidelines for herbal ingredients. We also hold quality certifications such as cGMP, FSSC22000, and ISO 9001, ensuring full compliance for target markets.
