Good for my ADHD brain

I take this in combination with L-Thyrosine and Advanced DHA from Thorne to build back some of the energy lost over 40+ years of undiagnosed ADHD. I also take Elvanse/Vyvanse 60mg. When I take the Thorne supplements along with the meds I feel less drained than when I only take my meds.

Mold Detox

Using this product to detox the mold. This is a quality product with an ingredient that is helpful for removing mold. There is also a benefit to sleeping better with Phosphatidylserine. The size is not to large if you decide you don't like the product. The dosage is one pill a day.

Helps with Focus and Memory

After taking it consistently, I feel more focused and clear-headed. It really helps with memory and mental performance, especially during work or study. Caution: Those on blood-thinning medication or with bleeding disorders should avoid without medical advice.

It's letting me sleep through the night

I used to wake up and read two hours in the middle of the night. Now I either sleep through or awakened for a few minutes, turn over and continue that gorgeous sleep

Necessary and hard to find

Very good product. Necessary and almost never found in modern peoples’ diets unless you eat brain, etc. I eat wild whole oily fish so I actually get some but most people don’t

Short term highly effective

I used this nightly for a few months to help with cortisol spikes, neck tension, and middle of night waking. Initially I found massive relief, especially in tension and sleep. Then it seemed less noticeable when I’d take it and I stopped after a few months and didn’t notice a shift with or without. If I have high stress and brain fog I would consider it a tool.

Great for morning anxiety

I love this product. It helps me with morning cortisol spikes that leave me anxious, hot and sleep deprived. I take one before bed. Together with magnesium, I am much calmer all around.

Better sleep and manageable stress

I had a positive experience with this phosphatidylserine supplement. After taking it consistently, I noticed I wasn’t waking up around 3–4 a.m. anymore, which made a big difference in my overall sleep quality. My stress levels also felt lower and more manageable throughout the day, which was a pleasant surprise. The only downside for me is that it’s a bit on the pricey side, but the quality is excellent and it worked well enough that I would still consider buying it again.
