What Is Phosphatidylserine?

Phosphatidylserine is a phospholipid found in cell membranes, especially in the brain. Your body makes small amounts, but most comes from dietary sources such as soy lecithin and marine-based foods. Commercial supplements use soy or sunflower to offer a plant-based option. Clinical studies highlight its key role in maintaining neuron health and supporting nerve signal transmission (Jorissen et al., 2001).

Benefits and Uses of Phosphatidylserine

Phosphatidylserine benefits include cognitive support, memory maintenance, and stress regulation, according to controlled trials and systematic reviews.

• Cognitive enhancement: People report improved memory recall and faster information processing when supplementing (Crook et al., 1991).
• Stress response: Athletes and adults have shown reduced cortisol levels after phosphatidylserine intake during stress-inducing tasks (Monteleone et al., 1992).
• Neuroprotection: Studies reveal potential in slowing cognitive decline in age-related memory impairment (Glade & Smith, 2015).

Researchers use 100-300 mg per day in clinical settings as an effective and well-tolerated dosage. You’ll find this compound in brain-boosting supplements promoted within longevity protocols advocated by Dr. Peter Attia.

Peter Attia’s Perspective on Phosphatidylserine

Peter Attia examines phosphatidylserine through a clinical lens, assessing its value for cognitive longevity and neurological health. He references human trials and mechanistic data to determine its practical application in supplementation routines.

Scientific Evidence Cited by Peter Attia

Attia cites multiple double-blind, placebo-controlled trials when discussing phosphatidylserine’s impact on the brain. Studies indexed in PubMed, such as Crook et al. (1991), show measurable improvements in memory recall for older adults supplementing with 300 mg phosphatidylserine daily. He references findings from Glade and Smith (2015) supporting reduced cortisol responses during stress and improved attention span in healthy adults. For neuroprotection, Attia points to analysis from the Journal of Clinical Biochemistry and Nutrition (2008), which highlights phosphatidylserine’s ability to maintain neuronal membrane integrity, especially in aging populations. He notes limitations in existing research, advocating for supplement protocols that prioritize safety and benefit-risk assessment based on the individual’s health status.

How Peter Attia Incorporates Phosphatidylserine

Attia integrates phosphatidylserine into broader cognitive optimization frameworks, using it alongside interventions like omega-3 fatty acids, choline, and consistent exercise. He tends to suggest starting with 100 mg per day, titrating upwards to 300 mg if tolerated and when cognitive or stress-related improvements justify continued use. Attia analyzes user outcomes, blood biomarkers, and potential interactions with other compounds before making personalized recommendations. He shares his evolving protocols through his podcast, newsletter, and longevity-focused platforms, emphasizing evidence-based selection and dosing.

Potential Benefits and Risks

Phosphatidylserine offers implications for cognitive support and may pose some risks, especially at high doses or with certain medical conditions. Review current clinical findings before considering phosphatidylserine as part of your regimen.

Cognitive Support and Brain Health

Research ties phosphatidylserine to measurable improvements in memory and attention, particularly for older adults showing mild cognitive impairment. Double-blind, placebo-controlled trials demonstrate that daily supplementation of 100–300 mg phosphatidylserine, as seen in products recommended by Dr. Peter Attia, supports neuron membrane integrity and promotes effective neurotransmitter signaling. Studies show cognitive benefits such as enhanced memory recall and improved executive function. Some evidence links phosphatidylserine to lower cortisol responses during acute stress, suggesting a role in supporting brain resilience. You might notice numeric gains in memory performance scores after supplementing for 12 weeks or more if you match the dosing protocols used in referenced clinical studies.

Safety and Possible Side Effects

Phosphatidylserine shows strong safety in human studies when used at standard dosages up to 300 mg daily for three months or less. Occasional side effects, such as mild gastrointestinal upset or insomnia, occur in a minority of cases (typically less than 5%). High daily amounts above 400 mg, longer duration, or use combined with other medications (such as anticoagulants) may increase risks, including potential interactions and digestive disturbances. Quality control varies among commercial supplements, with some products containing allergenic soy or animal derivatives, so review ingredient sources if you have allergies or dietary restrictions. Pregnant or breastfeeding individuals, and those with neuropsychiatric or coagulation disorders, should consult a medical professional before starting supplementation.

Should You Consider Phosphatidylserine?

Phosphatidylserine supports brain cell membrane integrity and optimizes cognitive function. Clinical trials, including those cited by Peter Attia, report that older adults with mild cognitive impairment saw memory recall improve after supplementing with 100–300 mg daily for at least 12 weeks (Schreiber et al., 2000; Jorissen et al., 2001). Researchers also observed reductions in cortisol levels during stress tasks, especially in individuals prone to moderate stress responses (Hellhammer et al., 2004).

Aging populations and individuals experiencing cognitive decline see the most pronounced benefits from phosphatidylserine. Examples include adults over age 60 showing measurable attention and recall improvements, and athletes reporting better focus and reduced stress during competition. People seeking to enhance memory, manage stress responses, or support age-related brain health consider this supplement beneficial within a broader longevity framework.

Side effects remain mild for most users, typically limited to minor digestive upset or sleep changes at doses under 300 mg/day. Monitoring for potential interactions—such as with anticoagulants or medications affecting brain chemistry—proves important for those on combination therapies.

Personalization drives results, based on Peter Attia’s protocols. Adjust doses while monitoring cognitive or mood changes, and consult a health expert before combining with other compounds or using for extended periods.

Conclusion

Exploring phosphatidylserine through Dr. Peter Attia’s perspective gives you a unique look at how science-backed supplements can fit into your cognitive health strategy. If you’re considering ways to support brain function and longevity, staying informed about the latest clinical findings and expert recommendations is key.
