Ranked Solutions

Ranked by how much each one actually moves the needle — our SAC Efficacy Score™, explained further down.

1. #1

   Berberine

   Supplement

   0.7-1.0% HbA1c drop + 20-25% LDL reduction (30+ RCTs; Yin 2008 matched metformin)

   8.4/10SAC Efficacy Score™ⓘ

   • Effect size45%Large
   • Evidence40%Very strong
   • Reliability15%Works for most

   AMPK activation — the metformin-class mechanism. Yin 2008 matched metformin on HbA1c; ~0.7-1.0% HbA1c drop plus LDL reduction across 30+ RCTs. The strongest non-Rx glucose lever.

   Supplement

   • Effect size45%Large
   • Evidence40%Very strong
   • Reliability15%Works for most

3. #3

   Magnesium Glycinate

   Supplement

   restores the insulin-sensitivity cofactor; foundational, not flashy

   ⚑ mainly if magnesium-deficient

   6/10SAC Efficacy Score™ⓘ

   • Effect size45%Modest
   • Evidence40%Strong
   • Reliability15%Specific cases

   Magnesium status tracks insulin sensitivity — deficiency worsens glucose control. 300-400 mg/day restores the cofactor. Foundational, not flashy.

4. #4

   CoQ10 (Ubiquinol)

   Supplement

   modest blood-pressure support; most relevant for statin users

   ⚑ most relevant on statins

   5.7/10SAC Efficacy Score™ⓘ

   • Effect size45%Modest
   • Evidence40%Moderate
   • Reliability15%Specific cases

   Mitochondrial electron-transport cofactor + modest blood-pressure lever (Rosenfeldt 2007). Especially relevant for statin users. 100-200 mg/day with fat.

   #5

   Creatine Monohydrate

   Supplement

   ~1% HbA1c drop in type 2 diabetics — only with concurrent exercise (Gualano 2011)

   ⚑ needs exercise; shown in T2D, not healthy people

   5/10SAC Efficacy Score™ⓘ

   • Effect size45%Modest
   • Evidence40%Limited
   • Reliability15%Narrow

   Recruits the GLUT-4 glucose transporter to the muscle membrane — but the proven effect needs exercise. In type 2 diabetics who trained, 5 g/day cut HbA1c ~1% vs placebo (Gualano 2011). A training adjunct, not a standalone glucose lever.
