● Efficacy and Applications

Wholesale Phosphatidylserine oil is widely used in oil-based dietary supplements, health foods and other products. In formulation design, phosphatidylserine wholesale oil can better meet the needs of high-end products due to its solubility and uniform dispersion. For example, it can be combined with other fat-soluble nutrients to enhance the overall effect. It can be added to health products that require cognitive enhancement and psychological stress reduction. In addition, phosphatidylserine bulk oil can be used in certain specialty oil-based foods. Such as softgel products.

 

Advantages of Guanjie Biotech

Guanjie Biotech's wholesale phosphatidylserine products are from natural sources. This is mainly taken from soybeans or sunflowers.We are the phosphatidyl serine factory direct selling price. In addition, we use advanced HPLC-ELSD assay to ensure that the purity and quality standards of our products are at a high level. We also have a strict quality control system, where every step from raw material purchase to product shipment is strictly controlled to ensure that every batch of products provided to customers is of high quality.

 

Residual Solvent Phosphatidylserine Statement

The wholesale phosphatidylserine supplied by Guanjie Biotech is derived from Phosphatidylcholine, which is sourced from selected, qualified manufacturers. Therefore, this statement addresses the processing and residual solvent profile for both Phosphatidylcholine and Phosphatidylserine.

A. Residual Solvents in Phosphatidylcholine Processing

During the processing of Phosphatidylcholine, besides water, three solvents are used sequentially: Hexane, Acetone, and Ethanol. The residual levels of these solvents in the resulting our wholesale phosphatidylserine products are carefully controlled and must meet the following limits:

• Hexane – Not more than (NMT) 10 ppm

• Acetone – NMT 10 ppm

• Ethanol – NMT 3,000 ppm

B. Residual Solvents in Phosphatidylserine Processing

In the subsequent processing of wholesale phosphatidylserine, water is again used along with two additional solvents: Enzyme and Ethanol. The residual limits for these solvents in the final product are as follows:

• Enzyme – NMT 25 ppm

• Ethanol – NMT 3,000 ppm

These residual solvent limits for Guanjie Biotech's  pure phosphatidylserine are fully compliant with, and in many cases below, the standards set by the United States Pharmacopeia (USP) and the European Pharmacopeia (EP). They are deemed safe for human consumption and are either approved for use under FDA regulations or classified as GRAS (Generally Recognized As Safe).

In practical terms, the residual levels of Hexane, Acetone, and Enzyme in our Phosphatidylserine are consistently below 10 ppm, ensuring high safety and quality for consumers.

Regulatory and Safety Considerations

Under sections 201(s) and 409 of the Federal Food, Drug, and Cosmetic Act, and FDA regulations (21 CFR 170.3 and 21 CFR 170.30), a food substance may achieve GRAS status either through scientific procedures or through historical use in food prior to 1958.

• Scientific Procedures (21 CFR 170.30(b)):

Recognition of safety through scientific evidence requires the same quantity and quality of data necessary for food additive approval. This involves evaluation of generally available and accepted scientific data, which may include published studies or, when necessary, corroborated unpublished data, applying sound scientific principles.

• Experience-Based Recognition (21 CFR 170.30(c) and 170.3(f)):

Safety may also be established based on extensive historical use in food by a significant number of consumers, demonstrating a substantial record of safe consumption.

By adhering to these regulations, Guanjie Biotech ensures that wholesale phosphatidylserine is produced to the highest quality and safety standards, suitable for use in dietary supplements, functional foods, and other applications.
