Taghizadeh M, et al. - Authors systematically reviewed randomized controlled trials that assessed how garlic supplementation influences serum C-reactive protein (CRP) levels. They conducted a literature search of Scopus, PubMed, Cochrane Library, and Google Scholar up to January 2018. Findings revealed that serum CRP levels were reduced by garlic supplementation. Nonetheless, the reductions were linked to the supplemental doses and baseline levels of serum CRP. In studies with a daily garlic dose ≥1,200 mg/day, a significant decrease in CRP by 0.82 mg/L was seen; among studies with baseline CRP ≥2 mg/L, CRP was lowered significantly by 2.44 mg/L.
