Myo-inositol is a naturally occurring sugar alcohol that acts as an intracellular second messenger in insulin signaling pathways. By facilitating glucose uptake and improving insulin sensitivity, it helps mitigate metabolic dysfunction, a primary driver of biological aging. Its role in cellular signaling also supports neurotransmitter modulation and overall metabolic resilience, making it a valuable targeted tool for extending healthspan.
Verdict
Safe, effective targeted supplement for optimizing insulin sensitivity and metabolic health.

Protocol
- Take 2 to 4 grams daily, typically divided into two oral doses.
- Often combined with D-chiro-inositol in a 40:1 ratio to optimize metabolic signaling.
Flags
- Mild gastrointestinal distress (nausea, gas, diarrhea) may occur at doses exceeding 4 grams daily.
- May cause additive hypoglycemic effects if combined with insulin-sensitizing drugs like metformin.
- Bipolar disorder patients should consult a physician, as high doses may trigger manic episodes.
