Red Clover Isoflavones

Red Clover Isoflavones are standardized plant-based compounds, extracted and concentrated, from the flowers of Trifolium pratense L. Mainly composed of biochanin A, formononetin, genistein, and daidzein. These naturally occurring isoflavones can be standardized by modern extraction, purification, and quality control technologies, providing manufacturers with traceable, consistent, and standardized botanical ingredients that are ideal for large-scale product development. It is different from traditional raw herbal powders because they are more standardized, enabling the formulators to more precisely specify ingredients, improve the efficiency of the production process, and provide consistency in the finished products. It is considered to be the highest quality natural active ingredients for dietary supplements, functional nutrition, botanical beverage systems, gummies, capsules, and tablets, as well as novel plant-based formulations. Their high isoflavone concentration allows product developers to work with less product and yet achieve the same concentration of isoflavones. With the rising popularity of clean-label and nature-inspired product concepts, it is a growing favourite among brands looking for scientifically characterized, naturally derived, and sustainably sourced ingredients.

The combination of a very standardized isoflavone composition, formulation versatility, and consistent physicochemical properties makes Red Clover Extract very appealing to product developers and formulators. It is generally provided as a fine brownish-yellow or light brown powder that has good flowability and hence is easy to handle when blended, encapsulated, tableted, or loaded into powder filling devices. Biochanin A, formononetin, genistein, and daidzein are its main components that cause a clear phytochemical profile, which can be standardized at a specific concentration, increasing consistency among the different batches and the accuracy of the formulation. It is relatively stable under recommended storage conditions, from a technical point of view, which means that the quality of the product can be ensured during the production process and its shelf life. The ingredient can also be formulated in a variety of delivery systems such as capsules, tablets, gummies, powdered drinks, sachets, and botanical blends. Its highly active profile allows formulators to include lower amounts of this product in a formula to meet their target specification levels, allowing for efficient usage of formula space and manufacturing efficiency.

1. Keep in the Original Sealed Packaging

The material is already packed in industrial standard conditions and should be stored in the original, unopened packaging until it is used in production. This is to ensure the product quality in storage.

2. Store in a Cool and Stable Environment

Ambient temperature should be kept at a constant level, and there should be fewer fluctuations in the temperature in the warehouse, as this can affect the stability of the botanical ingredients in the long-term.

3. Protect from Direct Light Exposure

The product must be kept out of direct sunlight and strong artificial lights. The quality characteristics of the extract can be maintained due to the shaded storage area.

4. Control Humidity Levels

Ensure dry and ventilation condition in storage areas. To prevent powder agglomeration, try to avoid moisture, condensation, or high humidity.

5. Reseal Immediately After Opening

Containers must be tightly closed after material is withdrawn from the container and before it is used a second time to minimize unnecessary exposure to the air and environmental moisture in the case of partial-use batches.

6. Segregate from Strong Odors and Volatile Materials

When storing Trifolium Pratense Extract, avoid storing it in the vicinity of chemicals, solvents, fragrances, or other materials that have strong odors that may impact the quality of the raw materials during long-term storage.

7. Follow FIFO Inventory Management

Manufacturers are encouraged to use a "First In, First Out" inventory system to improve the inventory rotation and planning of production.

8. Maintain Clean Warehouse Conditions

Place on pallets or shelves in a clean and orderly warehouse area away from dust and contaminants that can be present on the floors, walls, and areas where the product is stored.

Red Clover Extract Powder is usually added as a standard botanical active ingredient at a specific amount in different delivery systems that depend on the specific formulation and product specification. Formulators typically incorporate the extract into carriers like maltodextrin, microcrystalline cellulose, or other botanical powders to ensure uniform content and filling in capsules. During the production of a tablet, the ingredient may be mixed with appropriate compression aids such as binders and disintegrants, and/or flowability aids such as excipients, to optimize compression and ensure uniform tablet weight. In case of powdered beverage mixes and sachet products, it is advisable to pre-blend the extract with a larger quantity of dry ingredients to evenly distribute the extract in the batch. It can be dispersed or incorporated into compatible liquid systems, after solubility and stability assessments following the initial stages of formulation, and may be combined with emulsification or suspension technologies, as appropriate for the specific formulation needs. In the development of a product, it is recommended that manufacturers run pilot-scale tests to help define the mixing time, particle size compatibility, and processing parameters to ensure even distribution of ingredients and consistent product quality. The extract is also compatible with other botanical extracts, vitamins, minerals, amino acids, and plant-based ingredients, offering a great degree of freedom for product concept development in the formulation of novel clean-label, multi-ingredient formulations.
