Frequently Asked Questions

What does phosphatidylserine do?

Phosphatidylserine is a vital phospholipid that supports brain cell structure and enhances cellular communication. It is commonly used to promote cognitive health and help manage stress by modulating cortisol levels.

How much phosphatidylserine per day?

Phosphatidylserine is typically taken in doses ranging from about 100 to 300 mg per day, often divided into two or three doses. However, optimal dosages can vary depending on individual needs, so it's best to follow specific product instructions or consult with a healthcare professional.

When to take phosphatidylserine?

Phosphatidylserine is often best taken with meals—typically split between morning and early afternoon—to optimize absorption and support steady cognitive function and stress management.

When to take phosphatidylserine for sleep?

For sleep, taking phosphatidylserine about 30 to 60 minutes before bedtime may help lower cortisol levels and promote a more relaxed state conducive to quality rest.

Best time to take phosphatidylserine?

Phosphatidylserine is typically taken with meals—often in the morning or early afternoon—to optimize absorption and support steady cognitive function and promote a more positive mood.

Is Double Wood Phosphatidylserine third-party tested?

Yes. Every batch is third-party tested by NutraSolutions USA in Deer Park, NY — an ISO/IEC 17025:2017-accredited laboratory (Accreditation No. 113907). The Certificate of Analysis covers identity, active phosphatidylserine content per serving, heavy metals (arsenic, cadmium, lead, mercury by ICP-MS against USP <2232> limits), and microbial screens (Total Plate Count, Yeast & Mold, Coliform, E. coli, Salmonella, Staphylococcus aureus per USP and AOAC methods). Manufactured in a cGMP-certified U.S. facility from globally sourced ingredients.

What does the Phosphatidylserine Certificate of Analysis confirm?

The COA confirms 300 mg of phosphatidylserine per serving, with content verified by the contract laboratory using HPLC or 31P-NMR methodology — the same methods used in published clinical research on PS. Heavy metals are verified below USP <2232> limits, and microbials (TPC, Yeast & Mold, Coliform, E. coli, Salmonella, Staph aureus) are within USP specifications. The PS source is soy-derived, and identity is confirmed against reference standards. The current batch COA is linked above for verification against the lot number on your bottle.
