I cannot say enough for how much this helped a relative that had Dementia. He got more alert, could think and speak much better from using this. The best part is that it is NOT a drug. It is incredible!!!

good
Verified Purchase
Good quality product and clear dosage, which was convenient for our regimen. We gave it to the child on the recommendation of a doctor as part of complex therapy. The advantage is that it has a neutral taste and is well tolerated. The size of the capsules is a bit too large for a child, but it is still possible to swallow without any problems.

I've been taking this for my son with ASD for a while now. He learned how to use the toilet, took off his diaper, and we've never had to go back. Now we take it periodically at school, and his concentration immediately improves, and he becomes calmer. The teachers sing his praises about how well everything is going, so we take it periodically. I squeeze it onto a spoon and wash it down with tea; he can't swallow capsules.

Brain fog
Verified Purchase
After contracting COVID-19, I had severe brain fog, and not a single day felt refreshed. I didn't feel like doing anything, but after taking this product continuously, I no longer feel like I have to worry about it. It was a big help.

This supplement was recommended in the genetic test results. After taking it, my thoughts became clearer and my concentration improved. I think it has a very positive effect on brain health. The quality of this brand is always top-notch.

I bought this for my child to boost their brainpower; they use their brain too much for studying every day and need to supplement their PS (Physical Energy Management System).

I remember taking this supplement for my head, and I think it helped me back then. The capsule size is neutral, the quality is good, as is the dosage. I think it's beneficial, but not for everyone; I need to test it.

I bought Jarrow Formulas PS100 Phosphatidylserine 100 mg and want to share my impressions. The product comes in a small plastic jar with a tight-fitting lid. The jar is neat, and the label lists the name, dosage, and ingredients. Inside are softgel capsules that are easy to remove and store. The capsules themselves are small, smooth, and easy to swallow. There is almost no odor. I take PS100 to support my memory, concentration, and nervous system. Phosphatidylserine is a substance that is part of cell membranes and is especially important for brain function. After taking it for a while, I noticed that I became calmer, concentrated more easily, and felt less fatigued from mental work. Overall, I liked this product—the packaging is convenient, the capsules are easy to take, and the ingredients are good. 👍

High-Quality Ingredients: This product uses Sharp-PS®, a concentrated form of phosphatidylserine made from sunflower lecithin (soy-free), which ensures superior stability.
