Benfotiamine vs Coenzyme Q10 (Ubiquinol)

Mechanism

Lipid-soluble thiamine derivative that improves cellular thiamine availability and helps reduce advanced glycation stress in high-glucose environments.

Contraindications

• None established at standard doses

Mechanism

CoQ10 functions as an essential electron carrier in the mitochondrial electron transport chain (Complex I to III and Complex II to III), directly supporting oxidative phosphorylation and ATP synthesis. In its reduced form (ubiquinol), it serves as a potent lipid-soluble antioxidant, protecting mitochondrial membranes and LDL particles from peroxidation. It also modulates the mitochondrial permeability transition pore (mPTP) and supports endothelial NO synthase coupling.

Standard Dosing

100-200mg ubiquinol daily

Timing

With meals containing fat. Morning or midday preferred (may be mildly energizing).

Cycle Duration

ongoing

Side Effects

• Mild GI upset
• Insomnia (if taken late)
• Rare: skin rash

Contraindications

• Caution with warfarin therapy (requires INR monitoring)
