Zeaxanthin microencapsulated powder is carotene like compound that are derived from Tagetes erectus marigold flowers too. The marigold flower is one of the botanically richest sources of lutein and zeaxanthin, two important pigments that naturally accumulate in the macular region of the human retina.
Marigold- sources of zeaxanthin have high value and are largely used in premium eye health supplements. Marigold zeaxanthin mainly occurs as the free after being properly processed, which makes it more readily absorbed and used by the human body as compared to cartridge zeaxanthin.
The use of latest microencapsulation technology ensures the protection of the active constituent from oxygen, water, light, and heat, thereby considerably enhancing its shelf life, as well as providing more flexible formulations of the product across different dosage forms.

Since our body is not able to produce lutein and zeaxanthin in its own way; we need to consume them either through food or through liquids. The dark green leafy vegetables have a small amount of lutein and zeaxanthin, but marigold flowers are a concentrated and sustainable source that can be utilised commercially.
marigold-extract-zeaxanthin-powder provides the natural source as well as the standardized purity. It is one of the optimal ingredients used in the production of high-quality vision support supplements, worldwide when compared to regular-carotenoid -powders because it combines a natural origin with standardized purity.
Digital lifestyles continue to grow everyday through exposure to blue light from smartphones, tablets and computers, and this continued trend fuels a growing demand by consumers for a natural ingredient to help protect their eyes.
Microencapsulation is more than just converting oil into powder form. This technology was created to improve ingredient performance during various stages of manufacturing all the way up to when it is being consumed.
The practical uses of microencapsulated marigold zeaxanthin:
For manufacturers wanting steady product quality, microencapsulation offers a dependable solution that keeps the natural advantages of marigold-based ze

Primary natural pigment found predominantly within retina's central portion making up part of sharpest vision, namely Macula. Consuming adequate amounts of zeaxanthin will keep retina healthy to see throughout all stages of one's lifetime.
Zeaxanthin has a unique characteristic to absorb some amount of high energy blue light prior to entering the area of the eye with the most sensitive retinal tissue, resulting in its being identified as one of the most protective and vital nutrients for those who spend a lot of time using digital devices.
Zeaxanthin neutralizes free radicals which are the major causes of oxidative stress which leads to the degradation of the visual function. Zeaxanthin also neutralizes free radicals which are harmful to oxidative damage to retinal cells which are sensitive.
With the growing population that is aging and experiencing greater amounts of digital screen time globally, the ability to maintain good visual performance will be an important component of long-term wellness. Zeaxanthin supplementation (in the daily form of powderized zeaxanthin supplementation) is an easy way to maintain the daily consumption levels of eye nutrition with zeaxanthin.
More consumers want naturally sourced ingredients that look clean on labels. Zeaxanthin from marigold meets this need and works

Carotenoid ingredients have limited water dispersibility which makes them a challenge to formulate. Commonly produced zeaxanthin powders are susceptible to sedimentation, non- homogeneous dispersion and low stability in beverages.

· Functional Beverages
· Instant Nutritional Drinks
· Fruit Juice Supplements
· Oral Liquid Formulations
· Solid Beverage Powders
· Effervescent Drink Mixes.
Zeaxanthin stays fat-soluble, but specially designed microcapsules boost dispersion, production efficiency, and look in final
