Table 2

Influence of vitamin C supplementation on oxidative stress markers and vitamin C status in regular training group.

	Before supplementation	After supplementation	value
MDA (µmol/L)	4.26 ± 0.97	3.30 ± 0.65	<0.001
Vitamin C (µmol/L)	62.27 ± 9.68	88.83 ± 16.85	<0.001
Asc (µmol/L)	21.23 ± 7.57	31.1 ± 9.76	<0.001
DHA (µmol/L)	41.03 ± 8.76	57.73 ± 10.11	<0.001
Ratio of DHA/Asc	2.16 ± 1.02	1.99 ± 0.53	0.14
MPO (U/L)	68.83 ± 13.65	71.07 ± 17.13	0.45

Serum malondialdehyde (MDA), total vitamin C, ascorbic acid (Asc), dehydroascorbic acid (DHA), and myeloperoxidase activity (MPO) were measured in 30 male athletes before and after 14 days of vitamin C oral supplementation (2 g/daily). Differences were tested by paired-samples -test.
