DHA integrates into neural cell membranes, where it may support membrane fluidity and signaling involved in cognitive function.
Caution: Fish-derived oil may cause digestive upset for some; take with food to enhance tolerance.
Phosphatidylserine is a key membrane phospholipid that may support neuronal communication and stress-related signaling in the brain.
Caution: May interact with stimulants or affect sleep in sensitive individuals; avoid taking close to bedtime if you notice restlessness.
GLA is converted to signaling compounds that may help balance inflammatory pathways and cell membrane function.
Caution: May cause mild gastrointestinal discomfort; take with meals to reduce stomach upset.
Vitamin E acts as a fat-soluble antioxidant that helps protect polyunsaturated fatty acids in cell membranes from oxidative damage.
Caution: High intakes can thin the blood; consult a professional if you use anticoagulants.
EPA contributes to the production of signaling molecules that may support a balanced inflammatory response.
Caution: Fish oils can have a mild blood-thinning effect; use caution if combining with anticoagulant supplements or medications.
DHA and phosphatidylserine provide structural and signaling support for brain cell membranes, which may aid effective neural communication. GLA and EPA contribute fatty acid mediators that influence membrane composition and a balanced inflammatory response, while vitamin E helps protect these delicate fats from oxidation.
