Phosphatidyl serine (PS) is naturally produced in the brain, although its production dwindles as we age. This molecule is a type of phospholipid, which has one water-soluble side and one fat-soluble side. These properties allow phospholipids to form a double layer that makes up the outer membrane of each of our cells.
The protective coating of the brain and nerve cells is also composed of phospholipids. Natural health practitioners often recommend PS for Memory, Alzheimer’s disease, Sports Injuries, and even Depression.
Understanding Cell Membranes
The contents of each cell in your body are surrounded and protected by a double-layered phospholipid sac. This cellular membrane holds signal molecules and receptors that allow the cell to communicate with the outside world. The more fluid and flexible the cellular membrane, the more easily it can communicate, making each cell more efficient. Also, as each of your cells becomes more flexible, this offers increased suppleness and flexibility in your tissues. This can help to provide healthier supple skin, more flexible muscles and better brain communication.
Phosphatidyl Serine's Role in Cell Membranes
Interestingly, PS is usually only found on the inner layer of cell membranes. The cell tightly controls this, until the time comes for that cell to die. When a cell has reached the end of its life, it begins flipping PS to the outer layer of the cell membrane, and this acts as a signal to the immune system that it is time to destroy that cell. Thus, sufficient PS in the body supports the proper removal of damaged and aged cells. It also plays a role in triggering blood clotting.
Top Health Benefits of Phosphatidyl Serine
Role in The Brain
If the cell membranes of nerves in the brain are not sufficiently fluid, then they cannot effectively transfer information and nerve signals. Over time, this can lead to cognitive decline. Sufficient PS present in the brain cells can result in better cognitive function. PS can also cross the blood-brain barrier to produce the brain chemicals (neurotransmitters) that aid in memory - particularly acetylcholine. It has also been shown to help boost mood in those with mental stress. In general, the brain can produce sufficient PS as it requires, but this production becomes stunted during the absence of sufficient B Vitamins and Essential Fatty Acids. Interestingly, one study found that supplementation with PS can improve ADHD symptoms. Further research is required to confirm these results.
Role in Athletic Training
Supplementation with PS has been shown to promote faster exercise recovery and prevent muscle soreness. It has also been shown to support a healthy hormonal balance in athletes and can help to reduce or prevent some of the side effects of overtraining.
Tips For Taking Quality Phosphatidyl Serine Supplements
PS supplements are available in capsules. It is naturally present in animal tissues, particularly those from the brain, liver and kidney. Now, PS supplemental use is commonly produced from soybeans due to recent mad cow scares. Because of this, individuals with soy sensitivities should not use PS supplements. The recommended maintenance dosage is between 100-300mg daily, although some practitioners may recommend a loading dose of 300-500mg daily for 2 weeks before starting the maintenance dose.
