Phosphatidylserine (PS) is a natural phospholipid that plays a vital role in cellular function, especially within the brain, where it helps transmit messages between nerve cells. While often promoted for its benefits in memory and cognitive health, it is not suitable for everyone. Certain medical conditions, concurrent medications, and life stages necessitate caution or complete avoidance of phosphatidylserine supplementation.
Individuals Who Should Exercise Caution
People Taking Blood-Thinning Medications
One of the most significant reasons to avoid phosphatidylserine is its potential for blood-thinning effects. This mild anticoagulant property means it can interfere with medications designed to prevent blood clots. Individuals on prescription blood thinners, such as warfarin (Coumadin), heparin, or antiplatelet drugs like clopidogrel (Plavix), should not take PS without medical supervision. Additionally, combining PS with anti-inflammatory drugs like NSAIDs (e.g., ibuprofen) or other natural blood-thinning supplements, such as ginkgo biloba, can increase the risk of bleeding.
Pregnant and Breastfeeding Individuals
There is a general lack of sufficient, reliable information regarding the safety of phosphatidylserine for women who are pregnant or breastfeeding. To err on the side of caution, most healthcare professionals and supplement manufacturers advise against its use during these periods. Until more research confirms its safety, it is best for expectant and nursing mothers to avoid PS supplements.
Those with Bleeding Disorders or Upcoming Surgery
Given its potential to affect blood clotting, individuals with pre-existing bleeding disorders should strictly avoid phosphatidylserine. The supplement could exacerbate their condition and increase the risk of excessive bleeding. Similarly, anyone with scheduled surgery should discontinue PS supplementation at least two weeks beforehand to minimize bleeding risks during the procedure. Specific conditions like sickle cell anemia and antiphospholipid syndrome require extreme caution due to increased blood-clotting risks.
Individuals with Allergies
Supplements are most commonly derived from soy or cabbage. Therefore, people with known allergies or sensitivities to soy should avoid soy-derived phosphatidylserine. Some products may also contain other allergens, so it is crucial to read labels carefully and choose supplements sourced from non-allergenic ingredients if necessary, such as sunflower.
Children and Adolescents
While some research has explored PS use in children for conditions like ADHD, the long-term safety and optimal dosage are not well-established. Unless a healthcare provider specifically recommends it and supervises its use, children and adolescents should typically avoid phosphatidylserine supplements.
Potential Drug Interactions
Phosphatidylserine can interact with several types of medications by affecting neurotransmitter levels, particularly acetylcholine.
Comparison of PS Drug Interactions
| Drug Type | Mechanism of Interaction | Example Medications | Potential Outcome |
|---|---|---|---|
| Cholinergic Drugs | PS can increase acetylcholine levels. Combined with other drugs that also boost acetylcholine, this may amplify effects and increase side effects. | Alzheimer's drugs (e.g., donepezil), Glaucoma eye drops (e.g., pilocarpine) | Increased risk of side effects from both PS and the medication. |
| Anticholinergic Drugs | PS increases acetylcholine, which these drugs are designed to block. | Antihistamines (e.g., diphenhydramine), Parkinson's medications (e.g., trihexyphenidyl) | PS may decrease the overall effectiveness of the anticholinergic medication. |
Important Considerations for Medical Conditions
Individuals with specific medical conditions should always consult a healthcare provider before starting PS. Beyond bleeding disorders, those with pre-existing liver or kidney disease should seek medical advice, as the safety of PS has not been established for these conditions. Severe age-related neurodegenerative diseases should also not be self-treated with PS. It is essential to receive a proper diagnosis and treatment plan from a physician.
What to Do Before Taking Phosphatidylserine
- Consult a professional: Before starting any new supplement, talk to a doctor or pharmacist, especially if you have a pre-existing medical condition or take other medications.
- Discuss medications: Inform your healthcare provider about all prescription drugs, over-the-counter medications, and supplements you are currently taking to check for potential interactions.
- Plan for surgery: If you have surgery scheduled, make sure to stop taking phosphatidylserine at least two weeks in advance.
- Check for allergies: Scrutinize the supplement label to ensure it does not contain ingredients you are allergic to, particularly soy.
- Avoid self-treatment: Do not attempt to treat severe medical conditions with supplements alone. Seek professional medical guidance for proper diagnosis and care.
Conclusion
While phosphatidylserine is generally well-tolerated and offers potential cognitive benefits, it is not a universally safe supplement. Individuals on blood thinners or certain cholinergic/anticholinergic medications should proceed with extreme caution or avoid it entirely due to significant interaction risks. Pregnant and breastfeeding women, those with bleeding disorders, and people preparing for surgery also need to avoid PS. Always prioritize a consultation with a qualified healthcare provider to determine if phosphatidylserine is right for your specific health profile. The potential for serious complications, while rare, makes a cautious and informed approach essential.
