The Science

Why the 5-Pathway Approach Matters

Single-ingredient limits

Most blood sugar supplements rely on a single ingredient — usually berberine. Berberine is well-studied, but it addresses one mechanism of glucose control. If your body needs support in multiple areas, one ingredient can't cover them all.

Proprietary blend problems

Glucocil's 14-ingredient proprietary blend sounds impressive until you realize you can't verify individual doses. "2,250mg of active ingredients" is a marketing number — the actual dose of each compound inside that blend is undisclosed. IntelliSync discloses every ingredient and every dose on the label.

Five pathways, one capsule

IntelliSync combines five ingredients at clinically-studied doses — Berberine (AMPK activation), Chromium (insulin sensitivity), Fenugreek (carb absorption), ALA (oxidative stress), Banaba (glucose uptake). Each targets a different mechanism. Together, they cover the major pathways glucose management depends on. See how this compares to metformin →
