Brain fog is often dismissed as stress or a busy lifestyle, but it can also be a signal of an underlying metabolic imbalance.
The brain depends on stable energy and efficient glucose metabolism to function optimally.
When blood sugar regulation is poor, it may affect:
• Focus
• Memory
• Mental clarity
• Energy levels
• Cognitive performance
Insulin resistance, chronic stress, inflammation and poor sleep can all contribute to brain fog and reduced cognitive function.
Supporting metabolic health supports brain health, too. Understanding your baseline health may help identify the root cause of persistent cognitive symptoms.
