Vitamin C [mean difference (MD), -0.342; 95% confidence interval (CI), -1.090-0.407; p >0.05), folic acid (MD, -1.463; 95% CI, -7.133-4.208; p >0.05), and selenium (MD, 0.350; 95% CI, -0.687-1.387; p >0.05) levels did not differ between the groups.
Both Boron and Copper are closely matched — the best choice depends on your specific health goals.
For bone health, Boron has a higher relevance score (82 vs 72).
