Introduction

Inositol is a vitamin-like compound often referred to as Vitamin B8 (though it is not officially classified as a vitamin). It plays a key role in cell signaling, insulin sensitivity, neurotransmitter balance, and hormonal regulation.

Inositol is especially well known for its benefits in PCOS, fertility, anxiety, mood disorders, and metabolic health.

What Is Inositol?

• A naturally occurring carbohydrate compound
• Structural component of cell membranes
• Essential for insulin and neurotransmitter signaling
• Produced by the body and obtained from food

• Acts as a second messenger in cell signaling
• Improves insulin receptor sensitivity
• Supports serotonin, dopamine & GABA pathways
• Balances hormonal and metabolic signals

Insulin Sensitivity & Metabolic Health

• Improves insulin sensitivity
• Reduces insulin resistance
• Supports healthy blood sugar balance
• Helpful in metabolic syndrome & prediabetes

PCOS, Fertility & Hormonal Balance

• Improves ovulation & menstrual regularity
• Reduces androgen (male hormone) excess
• Improves egg quality
• Widely used in PCOS & fertility protocols

Anxiety, Mood & Emotional Regulation

• Reduces anxiety & panic symptoms
• Supports mood stability
• Helpful in OCD & stress-related disorders
• Non-sedating calming effect

Brain Signaling & Neurotransmitter Support

• Improves serotonin signaling
• Supports GABA balance
• Enhances neural communication
• Supports cognitive clarity

Sleep Quality & Nervous Calm

• Calms the nervous system
• Supports sleep onset
• Reduces stress-related sleep disturbance

Signs of Low Inositol Activity

• Insulin resistance
• Irregular periods or PCOS symptoms
• Anxiety or panic attacks
• Mood instability
• Cravings & metabolic imbalance

Who Benefits Most from Inositol?

• Women with PCOS or fertility concerns
• People with insulin resistance
• Anxiety or panic disorder sufferers
• Individuals with mood imbalance
• Those seeking metabolic & hormonal balance

Natural Sources of Inositol
