Phosphatidylserine, a key component in cell membranes, offers numerous health benefits. Widely known for its role in supporting brain health, this supplement has been linked to improved memory and cognitive function. Studies also suggest it may help reduce stress and enhance athletic performance, making it a versatile addition to health regimes. With its natural presence in the body and in certain foods, phosphatidylserine supplements are gaining attention for their role in maintaining overall well-being.

What Is Phosphatidylserine?

Phosphatidylserine is a fatty substance produced in the body that covers and protects every cell and is vital in the functioning of nerve cells within the brain. As a phospholipid, it plays a key role in ensuring cell membrane integrity and fluidity. This substance is essential for the proper functioning of nerve cells within the brain and is instrumental in transmitting messages between them.

While the body can synthesize phosphatidylserine, the majority of it comes from our diet. It is found in certain foods like soybeans, egg yolks, and chicken liver. However, the modern diet often lacks sufficient amounts, making supplementation a consideration for many people.

Supplementation of phosphatidylserine has gained popularity due to its potential benefits, particularly in brain health. It has been studied for its role in enhancing cognitive functions such as memory, concentration, and learning. Additionally, it is believed to have a calming effect on the brain, which may help reduce stress and improve mood.

What Are the Benefits of Phosphatidylserine?

Phosphatidylserine, a phospholipid found naturally in the body and critical for brain health, has become a popular dietary supplement. Its supplementation is associated with various health benefits, particularly for cognitive functions. Here are the key health benefits of Phosphatidylserine:

  • Enhances Cognitive Functions: Phosphatidylserine is known for its ability to improve memory, focus, and concentration, making it beneficial for cognitive performance.
  • Supports Brain Health in Aging: It may help in reducing age-related cognitive decline and is often considered for use in conditions like Alzheimer’s and dementia. In Alzheimer’s patients given 300mg phosphatidylserine, vocabulary and picture matching scores increased after treatment. [PMID: 26345866]
  • Neuroprotective Properties: Phosphatidylserine may protect brain cells and support the overall health and functionality of neurons.
  • Cognitive Support and Memory Enhancement: Especially in older adults, potentially helping in the management of age-related cognitive decline.
  • Mood Regulation: Some studies suggest that Phosphatidylserine can have a positive effect on mood, potentially alleviating symptoms of depression and anxiety.
  • Improves Symptoms of ADHD: It’s been studied for its potential to improve attention, impulsivity, and hyperactivity in children and adults with ADHD.
  • Stress Reduction: Phosphatidylserine might help lower stress by reducing the production of cortisol, a stress hormone, particularly in response to physical stress.
  • Athletic Performance: By reducing stress and fatigue, it may improve exercise endurance and recovery in athletes. Cortisol increases in response to exercise. In a placebo-controlled study, 9 men took 800 mg/d phosphatidylserine for 10 days. This significantly blunted the ACTH and cortisol responses to physical exercise. The researchers concluded that phosphatidylserine may counteract stress-induced activation of the hypothalamo-pituitary-adrenal axis. [PMID: 1325348]
  • Mood Regulation: Positively impacting mood and potentially beneficial for symptoms of depression.
  • Attention and Behavior Improvement in ADHD: Beneficial for managing symptoms of ADHD in both children and adults.

Is Phosphatidylserine Safe?

Phosphatidylserine is widely recognized for its safety as a dietary supplement. This natural compound, found abundantly in the human body and various foods, has been extensively studied and generally regarded as safe for consumption. When taken as a supplement, it has shown minimal to no adverse effects in numerous research studies, underlining its safety profile. The body’s inherent familiarity with phosphatidylserine, due to its natural presence in cell membranes, particularly in the brain, contributes to its high tolerability and low risk of side effects. This makes phosphatidylserine supplements a reliable choice for those looking to enhance cognitive function and overall brain health.

Medication Interactions with Phosphatidylserine

  • Anticoagulants and Antiplatelet drugs (e.g., Warfarin, Aspirin): Phosphatidylserine might increase the blood-thinning effect of these drugs, potentially increasing the risk of bleeding.
  • Acetylcholinesterase Inhibitors (e.g., Donepezil, Rivastigmine): Used for Alzheimer’s disease, these drugs might have their effects enhanced or altered when taken with phosphatidylserine, potentially affecting neurotransmitter levels.
  • Glucocorticoids (e.g., Cortisone, Prednisone): Phosphatidylserine may counteract stress hormone effects. When combined, it might reduce the effectiveness of glucocorticoids.
  • Timed-release Drugs: Phosphatidylserine could potentially alter the absorption rate of timed-release medications, affecting their efficacy.

Supplement Interactions with Phosphatidylserine

  • Omega-3 Fatty Acids (like Fish Oil): Phosphatidylserine may work synergistically with omega-3 fatty acids, potentially enhancing cognitive benefits. However, this combination might also increase the blood-thinning effect, similar to the interaction with anticoagulant medications.
  • Ginkgo Biloba: Both Ginkgo Biloba and Phosphatidylserine are known for their cognitive-enhancing effects. When taken together, they may amplify each other’s effects on memory and cognition. There is also a potential for increased risk of bleeding, similar to combining with anticoagulants.
  • St. John’s Wort: This herb is often used for depression and mood disorders. Combining it with Phosphatidylserine might enhance its mood-stabilizing effects, but it could also lead to unpredicted changes in neurotransmitter levels.
  • Vitamin E: As an antioxidant, Vitamin E may work synergistically with Phosphatidylserine to protect brain cells from oxidative stress. However, this combination might also potentiate the blood-thinning effect.

Food First!

Although this article discusses supplements in detail, don’t forget that we are absolutely committed to the “Food First” approach to nutrition. When it comes to your health, the totality of your eating habits far surpasses the impact of individual nutrients or any single supplement you consume. Even though this article doesn’t delve into the broader picture of your overall diet, it’s crucial to keep this element at the forefront of our minds. Your food needs to provide all the vitamins, minerals, fiber, and phytochemicals to nourish your body systems down to the cellular level.

Food choices, rather than supplements, are the most critical factors for a healthy gut microbiome. These trillions of tiny inhabitants in your gut affect your brain waves; they orchestrate your immune system. They possess the power to create molecules that can switch genes on or off and are even capable of synthesizing neurotransmitters. Opting for organic foods and steering clear of plastic packaging (including those labeled BPA-free) is a smart move to limit toxin exposure. The sum of all these parts leads to a powerful conclusion: the ultimate key to your health lies in the quality and balance of the food you consume. Supplements are secondary.

To Sum It Up

Phosphatidylserine supplements offer a range of health benefits, particularly in enhancing brain function and cognitive abilities. Studies suggest they may improve memory, concentration, and learning capabilities. Additionally, these supplements can help in managing stress levels and might even support athletic performance by aiding in recovery and muscle soreness. While naturally present in the body and certain foods, supplementation provides a straightforward way to access these benefits.
