Table 4.

Copper and iron concentrations in subjects divided by BMI into normal weight (<25 kg/m²) or overweight and obese (≥25 kg/m²) groups. An unpaired, two-tailed t-test was used to analyze significance between BMI groups. Mean ± SEM are shown.

		BMI < 25 (n = 51)	BMI ≥ 25 (n = 56)	p-Value
Copper	Baseline	918 ± 33	995 ± 30	0.08
	Intervention	847 ± 29	936 ± 29	0.03
Iron	Baseline	1107 ± 64	899 ± 47	0.008
	Intervention	779 ± 53	776 ± 40	0.97
