Bottom line
Curcumin (Turmeric) (evidence B, safety 5/5) has a stronger evidence base than Metformin (evidence A, safety 4/5). Curcumin (Turmeric) has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Curcumin (Turmeric) if
Curcumin (Turmeric) is the better fit when your goal aligns with its mechanism (Inhibits NF-κB transcription factor activation, suppressing dozens of downstream pro-inflammatory cytokines (TNF-α, IL-6, IL-1β)) and the dose range (500–2000mg) suits your protocol. Half-life is —h.
Choose Metformin if
Metformin is the better fit when your goal aligns with its mechanism (Activates AMP-activated protein kinase (AMPK), the cellular energy sensor that mimics caloric restriction signalling) and the dose range (500–2000mg) suits your protocol. Half-life is —h.
