Clinical studies on Phosphatidylserine

Studies in the elderly

Double-blind, placebo-controlled clinical studies of Phosphatidylserine show improvements in memory and also in motivation in elderly people with varying degrees of memory and cognitive deficits: 

1. Phosphatidylserine improves memory function in people with age-related memory decline (ARM). 

2. Phosphatidylserine improves behaviour and memory function in elderly people in "moderate to severe cognitive decline". 

3. Phosphatidylserine in the treatment of Alzheimer's disease: results of a multicentre study. 

4. Phosphatidylserine improves mood and social well-being in the elderly: observations from clinical studies. 

5. Phosphatidylserine has an activating effect on brain physiology: E.E.G. tracings, P.E.T. imagery.

 

Modes of action

Biochemistry of Phosphatidylserine, an essential component of neuronal membranes. Phosphatidylserine supplementation is based on the protection and stabilisation of neuronal membranes. The result is a physiological stimulation of the trans-membrane processes of neurotransmission.

 

An overview of experimental studies : 

1. Phosphatidylserine acts against the physiological ageing of neuronal membranes. 

2. Phosphatidylserine acts against the weakening of neurotransmissions associated with aging. 

3. Phosphatidylserine prevents age-related loss of dendritic density.

 

Phosphatidylserine in the French medical press

Medical journals such as Le Quotidien du Médecin, Nutranews, Protéus Network, have discussed the value of Phosphatidylserine supplementation in feature articles, including: 

1. Phyto-nutrients against brain ageing. 

2. A food supplement against age-related memory problems. 

3. GPC, Galantamine, PS, the new anti-ageing brain nutrients. 

4. Phosphatidylserine (PS) and age-related brain damage.
