Good for ME/CFS

Posted by Reviewer3147749 on Jun 01, 2010

My brain was slip-sliding everywhere. Just one of these at nights has made a real difference. I waited a long time to take this, as some references suggest the possibility increased inflammation. I'm glad I'm taking it now, problem-free.

This product is remarkable and the difference is noticeable within the first 3 weeks. I would recommend it to anyone who needs an etra boost for memory or cognitive function.

Been using before bed.

I take 3 before bed with some valerian. I've had very good sleep with these and I wake up feeling rested. Highly recommended also for stress reduction.

Others have recommended this for memory

It couldn't hurt to improve one's memory but I take it due to a genetic defect (CBS +/+) in the methyl cycle which PS is thought to moderate.

Orange Water

I've been taking a product called Seriphos to help with sleep, as recommended by my health practitioner. But it's been on back order for a while, and I replace it with Source Naturals Phosphatidyl Serine Matrix, because it's a similar product with a reasonable price. Although it seems to be an adequate substitute, it caused a disturbing change in my morning urine, turning it orange. I verified this as the cause, by eliminating it from my nighttime supplements, then adding it back.
