1.Natural Astaxanthin from Haematococcus pluvialis

Astaxanthin is a naturally occurring carotenoid found in certain microalgae, and Haematococcus pluvialis is one of the most important natural sources used for commercial natural astaxanthin production.

Natural astaxanthin is valued in the nutritional ingredient market for its antioxidant activity and carotenoid functionality, making it a high-value ingredient for dietary supplements, functional foods and other nutrition-oriented formulations.

The natural source is therefore an important distinction for manufacturers developing products positioned around naturally derived carotenoids. Our existing natural astaxanthin portfolio also uses Haematococcus pluvialis as the natural source.

 

2. Double Encapsulation Technology

The key technical feature of the 2.5%-S grade is its double encapsulation.

Astaxanthin is a sensitive carotenoid, and its stability can be affected by oxygen, light, heat and other environmental conditions. Encapsulation provides a physical barrier around the active ingredient, helping to reduce direct exposure to external factors during processing and storage.

A double encapsulation structure takes this protection concept further by using two encapsulation layers rather than a single encapsulation structure. The purpose is to create a more controlled microparticle system around the astaxanthin, supporting its stability and handling characteristics.

For this product, the value of double encapsulation is therefore not simply “more coating,” but the development of a more controlled physical form for a sensitive carotenoid intended for solid dosage manufacturing.

 

3.Why Microparticles?

This product is supplied as Microparticles, which is different from a conventional microencapsulated powder.

The microparticle structure provides a controlled particulate form of the encapsulated astaxanthin, making it suitable for dry blending and solid dosage processing.

For tablet manufacturers, this format can be advantageous because the ingredient can be incorporated into powder blends without handling astaxanthin as a liquid or oil-based material. Particle characteristics can also be considered together with the excipients, mixing process and compression requirements during formulation development.

The technology is therefore closely connected to the final dosage form: double encapsulation creates the protected structure, while the microparticle format provides the physical form required for tablet processing.

3.1Designed Specifically for Tablets

The 2.5%-S grade is not positioned as a general-purpose astaxanthin ingredient for every type of finished product. It is specifically developed for tablets and solid dosage formulations.

Tablet production requires ingredients that can be accurately dosed, uniformly blended and processed together with other powders. For sensitive active ingredients such as astaxanthin, the physical form of the ingredient can be just as important as the active concentration.

The microparticle format provides a dry, processable ingredient that can be incorporated into tablet blends, while the double encapsulation system is designed to provide additional protection for the astaxanthin during handling and processing.

This application-specific design makes the product particularly relevant to supplement manufacturers developing astaxanthin tablets.

3.2Antioxidant and Nutritional Applications

Natural astaxanthin is primarily valued as a carotenoid with strong antioxidant activity. It is used in nutritional supplements and functional food products where natural antioxidant ingredients are part of the formulation concept.

Its antioxidant properties, together with its natural microalgal origin, make astaxanthin attractive for products targeting areas such as daily antioxidant nutrition, heALT（替代文本）hy aging, skin wellness, eye heALT（替代文本）h and exercise-related nutrition.

For manufacturers, the combination of natural origin and a technically engineered delivery format allows the ingredient to be positioned not simply as a carotenoid raw material, but as a speciALT（替代文本）y natural active suitable for modern solid-dose formulations.

3.3Formulation Advantages

The technical value of this product comes from the interaction between the active ingredient and its physical form.

Natural astaxanthin provides the nutritional functionality; double encapsulation provides a protective structure; and microparticles provide a practical powder form for tablet manufacturing.

This combination can help manufacturers address several formulation considerations at the same time:

• Protection of a sensitive carotenoid during processing
• Convenient dry-powder handling
• Accurate raw material dosing
• Uniform incorporation into powder blends
• Compatibility with tablet manufacturing workflows
• More controlled physical form than unencapsulated astaxanthin

The final formulation should still be evaluated according to the tablet composition, excipients, mixing conditions, compression process and storage requirements.

 

4.Quality and Specification Control

For procurement and product development, the most important parameters are clearly defined:

Natural source: Haematococcus pluvialis
Astaxanthin content: 2.5%
Grade: 2.5%-S
Format: Microparticles
Encapsulation: Double Encapsulation
Application: Tablets

These parameters provide a practical basis for raw material qualification, formulation calculations and batch-to-batch quality control.

 

5.Key Product Characteristics

• Natural Astaxanthin from Haematococcus pluvialis
• 5% Astaxanthin
• 5%-S Grade
• Double Encapsulation
• Microparticle Format
• Specifically Developed for Tablets
• Antioxidant Carotenoid Ingredient
• Suitable for Solid Dosage Formulations
• Convenient Dry Powder Processing Format

 

6.Why Choose Natural Astaxanthin Microparticles 2.5%-S?

The main advantage of this product is the combination of natural astaxanthin functionality with a specialized delivery format for tablets.

The Haematococcus pluvialis origin provides a natural source of astaxanthin, while the 2.5% specification gives manufacturers a clearly defined active concentration. Double encapsulation is used to create a more protected structure around the sensitive carotenoid, and the microparticle format makes that structure practical for dry powder processing and tablet manufacture.

This makes the product particularly suitable when the objective is not simply to add astaxanthin, but to incorporate a natural astaxanthin ingredient engineered specifically for solid dosage applications.
