Short answer: GlucoZen contains ingredients — including Berberine, Cinnamon and Turmeric — that may lower blood sugar. If you have diabetes or take any blood-sugar or diabetes medication, please talk to your doctor before using GlucoZen.
Why this caution is placed prominently, not buried
This guidance appears under its own "Please Read First" heading before the ingredient breakdown — a deliberate placement signaling its importance.
Why blood thinners are a separate, additional caution
Turmeric, Resveratrol and Berberine may also interact with blood-thinning medication — a genuinely distinct concern from the blood-sugar-lowering caution, worth discussing separately.
⚠️ Worth knowing: so your medication and levels can be monitored safely — the specific, stated reason behind this caution, not a vague general warning.
