What is Lutein Microcapsule Powder?
Lutein Microcapsule Powder is a lutein ingredient derived from marigold in dry microcapsule form, suitable for manufacturers who are required to ensure consistent application, blending, and powder processing during production. It comes in standardized lutein specifications and can be used in dietary supplements, nutritional premixes, tablets, capsules, sachets, and dry formulations.

Built for Consistent Powder Handling
The performance of a lutein ingredient in the commercial manufacture of supplements is dependent on more than just assay. The flow of powders, their particle size distribution, bulk density, and blending characteristics may affect the accuracy of weighing, active distribution, filling efficiency, and consistency of the batch.
Lutein Microcapsule Powder is not provided as an Oil-based Lutein ingredient, but as a controlled dry powder. This makes it suitable for manufacturers whose current production process relies on dry treatment of goods.
The controlled particle size and density parameters of the current product specification provide formulators and production teams with the option to determine whether the ingredient meets their needs by testing the product through their blending and filling equipment.
Powder Performance in Production
Weighing & Dosing
The Standardized Lutein assay enables manufacturers to determine the amount of ingredient needed based on the desired level in the final product. This is especially true if relatively low levels of lutein are included.
Dry Blending
The free-flowing powder format can be mixed into suitable dry premixes containing other active ingredients. Order and blending time should be decided on the basis of the formulation.
Filling
Controlled powder characteristics allow better and more predictable powder movement during filling of capsules and sachets and during other powder dosing processes.
Compression
In the case of tablet products, it can be assessed in the dry-blending system. Compatibility with fillers, binders and lubricants and the compression process of choice should be evaluated by the formulators.

Which Manufacturing Formats Can Use It?
Tablets
Appropriate for dry-blend formulation of tablets where lutein should be evenly dispersed through the powder mix.
Hard Capsules
The powder format can be used to evaluate in hard capsule dosage forms where there is a need to regulate the amount of ingredient delivered along with dry filling.
Sachets & Stick Packs
For powdered nutritional products where accurate addition and consistent blending are critical.
Nutritional Premixes
The use of a standardized lutein assay allows this ingredient to be used in multi-ingredient premixes where an active-content calculation is desired.
Dry Nutrition Products
May be used as ingredients in some powdered nutritional and functional food products based on the finished product specifications.

Dosage Calculation
The addition rate required for B2B formulation should be based on actual lutein assay and not the total weight of the ingredient.
For example:
The amount of powder required = desired amount of lutein (µg) / Lutein assay (µg per 100 grams of powder).
A higher assay grade means that the powder contains fewer grams of powder per amount of lutein.
Kingsci is able to supply the specification and sample to enable manufacturers to specify the appropriate grade in relation to their target dosage and finished product format.
Handling & Storage
Store in a cool, dry place, out of direct sunlight, excessive heat, and moisture.
Resealing opened packaging should be done as soon as possible after use, as it can be affected by moisture exposure. Wherever possible, hold the material in its original packaging and adhere to the following FIFO inventory management.
