In our study, we looked at how phosphatidylserine supplementation affects mood and stress responses during an anxiety-inducing situation. Participants were divided into four groups, receiving different doses of phosphatidylserine before facing a mental stress test.
We found that the group receiving 400 mg of phosphatidylserine experienced lower stress hormone levels and reported feeling less distressed. However, larger doses did not bring the same benefits, indicating that the 400 mg dosage might be key in alleviating anxiety during stress.
These findings suggest that phosphatidylserine could be a promising option for managing stress-related issues.

Effective immediately, one tablet is great for anxiety feelings before stressful encounters. It alleviates waves of anger and sadness. I tried both capsule and tablet forms and found both work equally well. Although priced high, I’m concerned about low-cost options affecting its effectiveness.

I’ve been using this product for years; it’s the best for the price. Taking 2 each night helps manage my anxiety long term, with the option of an extra dose during the day if needed. Highly recommended!

Essential anxiety aid

This product is non-negotiable for me. Jarrow is a trusted brand, and I appreciate the easy-to-swallow softgels. P-Serine helps stabilise my mood, reducing anxiety and nightmares. In times of heightened anxiety, I increase my dosage for further calming effects.

Ineffective for anxiety
Pretty good! My doctor recommended it for anxiety, but it didn't seem to help me. However, I gave it to my mum as a sleeping aid and she said she has never slept better!
