se, standard error; AFE, polyphenol-rich extract from Aschophyllum nodosum and Fucus vesiculosus; AFCE, combination of polyphenols from Aschophyllum nodosum and Fucus vesiculosus and chromium; MANE, pure seaweed extract from Ascophyllum nodosum; UPE, fucoidan-rich extract from Undaria pinnatifida.

Values with different superscript letters within the same column are significantly different using Tukey's HSD test at P ≤ 0⋅05. Peak areas corresponding to specific M_w values (N 3).

¹Peak areas were calculated for the specific M_w ranges described earlier.
