Synergy

What is happening. Curcumin and berberine share overlapping anti-inflammatory pathways (NF-kB inhibition) and both have glucose-lowering effects. The combination may provide synergistic metabolic benefits.

Mechanism. Curcumin inhibits NF-kB and COX-2. Berberine activates AMPK and inhibits NF-kB. Both reduce inflammatory cytokines (TNF-α, IL-6) through complementary mechanisms.

Recommendation. Both can be taken together for complementary anti-inflammatory and metabolic effects. Monitor blood glucose if diabetic as the combined glucose-lowering may be significant.
