Phosphatidylserine With None Solvent Residue 20 - 70 % Natural
Plant Extract for Brain Health
Phosphatidylserine powder ( PS ) is from the phospholipids family,
which is the only one that could control the functioning of key
membrane proteins. Usually it refers to a series of compounds of
PS, in that the lipid - acetyl residues differs greatly in variety of product sources. Phosphatidylserine exists in
all biomembranes of animals, higher plants and microbes as an
important component of cellular phospholipids, for example, it
makes 10-20 % of total phospholipids in brains of mammals, and plays essential roles in many cellular
Phosphatidylserine powder, organic phosphatidylserine are
synthesized in the body of serine compounds, Italy, Scandinavia and
other European countries are widely used phosphatidylserine
supplements to treat dementia caused by old age and normal memory
loss in elderly .
