In 2026, a study published in Food Science & Nutrition evaluated a combination of phosphatidylserine and Ginkgo biloba in adults and reported favourable results in verbal memory tests.
Phosphatidylserine is a phospholipid found in neuronal cell membranes and contributes to their structure and function. In the study, it was combined with Ginkgo biloba, a plant researched in the field of cognitive function. Nutribiolite DHA-PS combines phosphatidylserine with DHA, an omega-3 fatty acid found in particularly high concentrations in the brain and retina.
Why phosphatidylserine is relevant to cognitive function
Phosphatidylserine forms part of the membranes of nerve cells. Its presence in brain tissue explains the scientific interest in this phospholipid in areas such as memory and cognitive function.
Phosphatidylserine used in supplements can be obtained from different lecithin sources, including soy and sunflower. Nutribiolite uses Sharp-PS® Green, a sunflower-derived, soy-free phosphatidylserine. The daily dose of DHA-PS provides 100 mg of phosphatidylserine.
The sunflower source provides a clearly identified plant-based source of phosphatidylserine while allowing DHA-PS to be formulated without soy lecithin.
Why Nutribiolite combines phosphatidylserine with DHA
DHA, or docosahexaenoic acid, is an omega-3 fatty acid found in particularly high concentrations in the brain and retina. DHA contributes to the maintenance of normal brain function and normal vision.
The beneficial effect on brain function is obtained with a daily intake of 250 mg of DHA. DHA-PS provides 500 mg of DHA per daily dose.
The balance between EPA and DHA defines the profile of a fish oil. As a reference, a conventional fish oil may contain around 18% EPA and 12% DHA.
Nutribiolite uses a fish oil especially concentrated in DHA, with 50% DHA and 10% EPA. This composition provides 500 mg of DHA per day and gives the formula a clear focus on the omega-3 associated with maintaining normal brain function.
The formula combines 100 mg of Sharp-PS® Green sunflower phosphatidylserine with 500 mg of DHA. It therefore brings together a phospholipid found in neuronal membranes with a high amount of one of the main omega-3 fatty acids present in the brain.
A formula specifically designed for brain wellbeing
DHA-PS brings together the key characteristics that define its focus on brain wellbeing.
- 100 mg of Sharp-PS® Green phosphatidylserine per day.
- Sunflower-derived, soy-free phosphatidylserine.
- 500 mg of DHA per daily dose.
- Fish oil with 50% DHA and 10% EPA.
- DHA in triglyceride form.
- IFOS-certified fish oil.
The high proportion of DHA, the sunflower-derived phosphatidylserine and the combination of both ingredients define a formula developed specifically around brain wellbeing.
DHA-PS combines 100 mg of Sharp-PS® Green sunflower phosphatidylserine with 500 mg of DHA in triglyceride form, from a fish oil containing 50% DHA and certified by IFOS.
Frequently asked questions about phosphatidylserine and DHA
What is phosphatidylserine used for?
Phosphatidylserine is a phospholipid found in cell membranes and is especially relevant in nervous tissue. It contributes to the structure and function of neurons and is researched in areas such as memory and cognitive function.
What is the difference between soy and sunflower phosphatidylserine?
The main difference is the source of lecithin used to produce it. DHA-PS uses Sharp-PS® Green derived from sunflower and is soy-free.
Why combine phosphatidylserine with DHA?
Phosphatidylserine forms part of nerve cell membranes. DHA is an omega-3 fatty acid found in particularly high concentrations in the brain and contributes to the maintenance of normal brain function. DHA-PS combines both in one formula.
How much DHA is needed for normal brain function?
DHA contributes to the maintenance of normal brain function with a daily intake of 250 mg. DHA-PS provides 500 mg of DHA per daily dose.
What is the advantage of a fish oil with 50% DHA?
A 50% concentration means that a high proportion of the oil itself is DHA. In DHA-PS, this composition provides 500 mg of DHA per daily dose and gives DHA a central role in the formula.
