Written by Joyce Smith, BS. A novel bioavailable blend of curcuminoids in a turmeric matrix significantly improved symptoms and biomarkers of rheumatoid arthritis in participating subjects. 

joint healthRheumatoid arthritis (RA), with an estimated prevalence of 40 to 100 million people worldwide 1, affects women 2-3 times more frequently than men, with a lifetime risk for women of 3.6% and 1.7% for men 1. In vitro and in vivo studies have demonstrated curcumin’s antioxidant, antineoplastic, antimicrobial, antiarthritic, antiamyloid, and anti-inflammatory properties 2,3. Curcumin’s poor intestinal absorption and limited systemic bioavailability 4,5 has sparked an intense effort to find more effective delivery systems and while nanoparticles and lyposomes and others have shown promise, search for increased water solubility and better intestinal absorption and bioavailability continues.

The present randomized, double-blind, three-arm pilot study 6, conducted in India, was designed to compare the efficacy and safety of two different doses of a novel highly bioavailable curcumin in a turmeric matrix formulation (Acumin™) with placebo in patients with active RA. Thirty-six patients were randomized in a 1:1:1 ratio to receive 250mg of Acumin™ as the low-dose curcumin, 500 mg as the high-dose curcumin, and placebo (500mg of food grade starch) to be taken as one capsule (twice daily) 30 minutes after meals for a 3-month period. Assessed study parameters included total cholesterol, random serum glucose, creatine, sodium, potassium, urea, total bilirubin, total protein, albumin, alkaline phosphatase, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), disease activity score 28 (DAS28), visual analog scale (VAS), American College of Rheumatology 20 (ACR20), total swollen joints, and total tender joints.

There were no significant changes from day one to end of treatment or intergroup changes between the 3 treatments groups with respect to the following measures: height, weight, body mass index, total cholesterol, random glucose, creatine, sodium, potassium, urea, total bilirubin, total protein, albumin, and alkaline phosphatase.

Compared to baseline values, the following statistically significant changes were seen:

  • VAS improved in all three groups: low-dose, 62.5%; high-dose, 72.3%; placebo, 3.5%
  • DAS-28 improved in low-dose (52.6%) and high-dose (66%) groups but was unchanged in placebo group
  • ESR decreased in each group: low-dose, 88.1%; high-dose, 88.6%; placebo, 29.6%
  • CRP decreased in each group: low-dose, 29.9%; high-dose, 51.2%; placebo, 11.3%
  • RF decreased in each group: low-dose, 80.2%; high-dose, 84.2%; placebo, 13.1%
  • ACR20 scores decreased in the low-dose (70.3%) and high-dose (75.7%) groups but was unchanged in the placebo group
  • Total joint swelling decreased in each group: low-dose, 80.4%; high-dose, 84.8%; placebo, 3.7%
  • Total joint tenderness decreased in each group: low-dose, 78.1%; high-dose, 88.0%; placebo, 4.4%

Compared to placebo, assessed improvements and inflammatory marker reductions were all statistically significant for both high- and low-dose treatment groups (P≤0.001) with the exception of the low dose Acumin™ for total joint pain [P≤0.01]). While the high-dose group experienced greater biomarker changes compared to the low-dose group, the assessed changes were not significantly greater. Both doses of Acumin™ were well tolerated and without side effects.
