Phosphatidylserine is the cognitive ingredient with the strongest regulatory standing.
Phosphatidylserine — usually called PS — is a phospholipid component of cell membranes, with the highest concentration in brain tissue. It's one of the most-studied cognitive supplement ingredients in dietary literature, and it occupies a unique regulatory position: it holds FDA's only qualified health claim relating to cognitive function, granted in 2003 under specific qualifying language. That qualified claim makes PS a foundational SKU in any nootropic, memory-support, or cognitive-aging product line — brands can reference the FDA review explicitly rather than relying solely on structure/function framing.
Operationally, PS is a focused capsule-format ingredient. Doses run 100mg to 300mg per capsule, the raw material is derived from lecithin (historically soy, now predominantly sunflower for clean-label positioning), and the production process is straightforward two-piece capsule fill. What separates a serious PS program from a commodity one is source documentation — sunflower vs soy, organic vs conventional, and the third-party verification that the capsule actually contains the declared PS content.
Phosphatidylserine source options
Sunflower-derived PS (soy-free)
The dominant US supplement choice. Sunflower lecithin yields phosphatidylserine that is functionally equivalent to soy-derived PS but lets the label declare "soy-free" — a meaningful positioning advantage in the allergen-conscious, clean-label consumer segment. Sourced through established suppliers with documented standardization. Premium per-gram cost vs soy is justified by the label story for most modern brands.
Soy-lecithin-derived PS
The historically dominant source — most of the original PS research used soy-derived material. Still available and cost-effective. Used in formulations where allergen-free positioning isn't a priority, or in budget-tier programs. Identity and PS content verified per batch on incoming raw material.
Multi-ingredient cognitive stacks
PS is a frequent foundational component in nootropic and memory-support blends. Common pairings: PS plus bacopa monnieri (memory consolidation), PS plus rhodiola or ashwagandha (cognitive performance under stress), PS plus B-complex with methylated folate (cognitive aging), PS plus l-theanine (focus formulations). Blend uniformity verified on every multi-ingredient production run.

The phosphatidylserine manufacturing process
- Discovery call. We discuss your target dose, source preference (sunflower vs soy), capsule shell, bottle configuration, MOQ, and timeline. Written quote within one business day.
- Formula review or development. Existing formula → component costing. New brief → formulators develop the blend (PS source, dose, excipients, co-actives) and produce bench samples.
- Sample approval. Production-representative samples are provided. Review, sign off, lock the formula.
- Component procurement. PS raw material, capsule shells, bottles, and labels sourced in parallel. Established supplier relationships keep timelines predictable.
- Production. Blending, encapsulation, and bottling run on Sun's in-house lines under full cGMP batch documentation. Blend uniformity verified before fill on multi-ingredient runs.
- Third-party testing. Every batch sampled for PS identity and content verification, and microbial safety. Certificate of Analysis issued before shipment.
- Packaging and labeling. Bottles labeled and case-packed to your channel-specific configuration — FBA-ready, retail-ready, or DTC. FNSKU for Amazon programs in-house.
- Fulfillment. Finished goods can ship from Sun's facility to your warehouse, Amazon FBA inbound, or to consumers and retailers through Sun's integrated fulfillment operation.

Compliance and label claims for phosphatidylserine
Phosphatidylserine is one of the few supplement ingredients with an FDA-recognized qualified health claim. The qualified claim — granted in 2003 — relates to phosphatidylserine and a reduced risk of cognitive dysfunction and dementia, with specific qualifying language the label must use verbatim. Beyond the qualified health claim, standard structure/function language ("supports memory and cognitive function," "promotes mental focus," "maintains healthy stress response") is permissible.
The qualified health claim is a regulatory asset — use it correctly and it gives the label a credibility weight most supplement ingredients can't carry. Use it incorrectly and it creates FDA enforcement risk. The qualifying language must appear verbatim where the claim is made; partial or paraphrased versions can violate the claim's authorization. We review label copy for compliance with both structure/function standards and the specific qualified claim language before any production commitment. Specific claim strategy is a decision you make with your regulatory counsel.
Frequently asked questions
What is the minimum order quantity for phosphatidylserine manufacturing?
Our standard MOQ for phosphatidylserine (PS) capsule programs is 5,000 units. Contact us with your target dose, source preference (sunflower vs soy), capsule format, and packaging — we return a written quote within one business day.
Sunflower-derived or soy-derived phosphatidylserine?
Both sources produce equivalent phosphatidylserine — the molecule is the same. The difference is the lecithin starting material and what that means for the label. Sunflower-derived PS is the dominant choice for current US supplement brands because it lets the label declare 'soy-free,' which matters in the clean-label, allergen-conscious consumer segment. Soy-derived PS remains the cost-effective alternative and the more historically-researched source. We work with both and recommend based on your brand positioning and price point.
What dose range do you typically manufacture?
Standard PS dose ranges from 100mg to 300mg per capsule. The 100mg-per-capsule format is the most common — it lets consumers take one to three capsules daily to hit clinical dose targets while keeping the capsule small. Higher doses (200mg, 300mg per capsule) are typical for practitioner-channel brands targeting clinical positioning. Custom doses available on request.
Can phosphatidylserine be formulated with other cognitive actives?
Yes. Phosphatidylserine is a common foundational ingredient in nootropic and cognitive-support multi-ingredient formulations. Common pairings include: PS plus omega-3 powder (cognitive support; note that softgel omega-3 is out of scope for Sun but powder formulations work), PS plus l-theanine (focus and calm), PS plus bacopa or rhodiola (memory and stress), and PS plus B-complex (cognitive maintenance stack). Blend uniformity is verified on every multi-ingredient production run.
What capsule shell materials are available for PS capsules?
PS capsules are produced in gelatin (bovine or porcine), HPMC (plant-derived, suitable for vegetarian positioning), and pullulan (plant-derived, suitable for vegan-certifiable labels). The sunflower-derived PS / plant-based capsule shell combination is the most common configuration for clean-label brands — keeps the entire SKU plant-derived end-to-end. Soy-lecithin-derived PS in a gelatin shell is the cost-effective baseline.
How long does phosphatidylserine manufacturing take?
Typical lead time is 6 to 8 weeks from final formula approval and component arrival to finished, COA-released goods. Sunflower lecithin PS sourcing is well-established and timelines are predictable. Repeat orders on established formulas move faster because raw material qualification and production procedures are pre-set.
What testing do you perform on phosphatidylserine batches?
Every PS batch undergoes third-party laboratory testing covering identity verification, phosphatidylserine content against the declared dose (label claim validation), and microbial safety panels (TPC, yeast, mold, E. coli, salmonella). The Certificate of Analysis travels with the production batch.
Are you FDA-registered and cGMP-compliant?
Yes. Sun operates an FDA-registered facility with SGS-certified GMP — an Amazon-qualified certification accepted by major big-box retail buyers. Every PS production run is documented under cGMP batch records, and third-party testing verifies content on every batch.
What structure/function claims are appropriate for PS labels?
Phosphatidylserine has FDA's only qualified health claim among supplement ingredients — relating to reduced risk of cognitive dysfunction and dementia, with specific qualifying language. Beyond the qualified claim, standard structure/function language ('supports memory and cognitive function,' 'promotes mental focus,' 'maintains healthy stress response') is permissible. Specific label copy is your call with your regulatory counsel; we review for structure/function compliance before any production commitment.
