The best for skin!

Chelsey L. May 16, 2024

I have struggled with cystic acne since having kids and stopping birth control. Within a week of starting this supplement, my acne has been looking so much better! I am feeling so much more confident and not needing to wear makeup to cover up. I also have Lyme and have struggled with word finding and memory issues. Since starting this, I feel like my thoughts are sharper, and I am not struggling as much with short-term memory.

Finally getting sleep!

Dan R. March 24, 2021

I had ongoing sleep issues for months. I could fall asleep fine but would wake up almost every night around 3 am with my mind racing. Taking this product before bed, along with the Magnesium Bisglycinate, has allowed me to get the sleep I need. While I do not have excellent sleep quality every night, overall sleep (and quality of life) have been improved with these two products.

Iso-phos

Alisa D. A. December 22, 2022

Best product I have tried to aid in getting quality sleep. Since I began using this product I have noticed a significant increase in the number of hours of deep sleep and REM every night. And even if I only get 5-6 hours of sleep I wake up feeling rested and refreshed.

Barbara January 29, 2026

reviews rated thorne as a high quality manufacturer. I haven't used it for long enough to objectively feel a difference. I'm trying to manage my excitability

Tish February 7, 2026

I tried Thorne Phosphatidylserine but honestly didn't notice any real changes, and it felt pretty expensive for what I got out of it.

Iso-Phos

Cathy P. June 15, 2022

I’m not sure how to rate this one because I imagine the results are gradual. I have not had any noticeable signs of memory improvement yet. Because my chiropractor recommended this for me I will continue to take it daily.

It didn't work

R April 21, 2026

Ordered it for better sleep, but it helped not even a bit, no matter what dose I took. Ultimately I reached a conclusion that PS is useless for me as PS from another company also didn't work for me. I love Thorne products, but this one was disappointing.
