What is the recommended dosage for Curcumin?

General: 500-1,000 mg/day curcuminoids; Enhanced Absorption: 150-500 mg/day (phytosome or piperine formulation)

What are the side effects of Curcumin?

Potential side effects include: Gastrointestinal discomfort (nausea, diarrhea, bloating), Headache, Yellow stool discoloration, Iron absorption interference at very high doses.

What is curcumin and how does it relate to immune function?

Curcumin is the primary bioactive compound in turmeric (Curcuma longa). It has been extensively studied for its anti-inflammatory properties, including modulation of NF-kB signaling, cytokine regulation, and support of both innate and adaptive immune pathways.

What dosage of curcumin has been studied for immune support?

Clinical trials have used curcumin at doses of 500–2,000 mg per day, typically as enhanced-absorption formulations (piperine-combined, liposomal, or phytosome). Standard curcumin has poor bioavailability without an absorption enhancer.

What are the potential side effects of curcumin?

Curcumin is generally well tolerated at typical doses. High doses may cause gastrointestinal discomfort, nausea, or diarrhea. It may interact with blood thinners and anti-inflammatory medications. Individuals with gallbladder issues should consult a doctor.

About

Curcumin, the principal curcuminoid of turmeric, inhibits NF-kB, MAPK, and NLRP3 inflammasome activation while activating the Nrf2 antioxidant pathway. An umbrella meta-analysis of 5,870 participants across 10 studies demonstrated significant reduction in CRP, IL-6, and TNF-alpha inflammatory markers.

How It Works

Inhibits NF-kB, MAPK, and NLRP3 inflammasome activation; activates Nrf2 antioxidant pathway; modulates macrophage, dendritic cell, T-cell, B-cell, and NK cell function; suppresses COX-2 and pro-inflammatory cytokine production.
