Too little
- Phospholipid membrane dysfunction symptoms:
- Poor cellular membrane integrity and function
- Compromised neurological function and brain health
- Reduced cellular communication and signaling
- Metabolic dysfunction and poor energy production
- Accelerated membrane aging and cellular damage
- Suboptimal brain and nervous system function
Too much
- Generally safe with potential for mild adverse effects:
- Digestive discomfort including nausea and stomach upset
- Allergic reactions in sensitive individuals
- Unknown long-term effects due to limited research
- Safe for short to medium-term use at appropriate doses
