Brain fog is a relatively general term for an unfortunately common symptom of everything from sleep loss and stress to hormonal problems and long COVID. Since it describes a general feeling of confusion or disorientation — or “feeling scattered” — just about anyone can feel brain fog. Your experiences will vary, and Focus Factor is a supplement, not a medication. It can’t treat (or diagnose, cure, or prevent) any illnesses — or symptoms of them. However, our testers experienced an improved sense of clarity soon after starting Focus Factor. (If you’re experiencing brain fog, reach out to your doctor first. There’s a chance it could be a medical concern treatable with prescription medications.)
