Has some efficacy, as opposed to several other PS supplements not bound to DHA that I've tried in doses up to 1g.
3-4 capsules of this one seems to mildly help with my sleep maintenance issues, not as much as I'd hoped and too expensive at that dosage. So back to eating Atlantic mackerel every night.
The best form of phosphatidylserine out there.
Its bound to dha which makes it the form thats in the cellmembranes of the brain.
It is more bioavailable and can cross the blood brain barrier more easily, making it stronger then other forms.
Its great for enhancing sleep quality, memory and reducing stress.
I bought this product for my mom, who is suffering from cognitive decline. I write this review after 3 months of use. it is difficult to give an opinion, honestly I seem to have noticed a small improvement in his cognitive abilities but certainly nothing striking. however I recommend it
