Description
PHOSPHOLIPID INGREDIENT
Phosphatidylserine Powder 50%
Phosphatidylserine powder is supplied standardised to a declared phosphatidylserine content of 50.0% on a food-grade carrier, released against a batch-specific certificate of analysis. This grade is used where a higher phospholipid loading is required in a smaller dosage, so the carrier and the dispersibility matter more than at lower contents. It is an ingredient for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the phosphatidylserine figure, the analytical method, the source and the carrier before approval. At this content the powder is less free-flowing than lower grades, so confirm the handling and blending behaviour in the buyer’s own process before committing to a volume.
- Phosphatidylserine: 50.0%, released against the batch COA.
- Source and carrier stated for label purposes.
- Handling and blending behaviour confirmed against the buyer’s process.
- Particle size and packing agreed at quotation.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
Phosphatidylserine is offered at 20%, 50% and 70%. The three are separate products with different carrier ratios and different handling behaviour. A 50% grade should not be substituted with a 20% grade on a price comparison, because the delivered phospholipid per kilogram is different.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
Application Areas
