TNF-α
According to The exercise test performed in the T-1 period did not show any significant changes in the level of IgG in both the placebo and supplemented groups. After three months of supplementation, however, there was a significant increase in IgG in the supplemented group compared to the control (placebo) group at all time points (pre-exercise, post-exercise, and 3 h restitution) (In both the supplemented and placebo groups, the intensive exercise tests performed in the T-1 period caused a significant post-exercise increase in IL-10, and this decreased after 3 h of recovery (In T-1, the level of IL-6 in the placebo group gradually increased after the exercise test and reached a significant difference after 3 h of recovery (There was no effect of intense exercise on TNF-α levels in T-1. In T-2, after the intense exercise test, a significantly higher level of TNF-α was observed in the placebo group after 3 h of recovery than in the control group. The changes in TNF-α levels were the greatest after 6 months of supplementation (T-3) (In T-1, after the exercise test in the supplemented group, a significant increase in iron levels was observed after 3 h of rest. In the placebo group, an increase in the iron concentration was observed in post-exercise values and remained increased after 3 h of restitution (In the T-2 period only, a significant increase in hepcidin after exercise compared to pre-exercise values was observed in the control group (The TIBC levels increased after the exercise test in each trial in both groups. During the period of restitution, the levels usually decreased to resting values (T-1: In T-1 and T-2, in both groups, the levels of UIBC increased significantly after exercise and decreased after 3 h of recovery (T-1: The exercise test performed in T-1 caused an increase in cortisol levels in the supplemented group after 3 h of recovery (The testosterone levels after the exercise test performed in the T-1 and T-2 periods increased significantly compared to pre-exercise values during the 3 h of recovery (T-1: In T-1, no significant changes were observed in lactoferrin levels after the exercise test. In T-2, in the supplemented group, the level of lactoferrin significantly decreased after exercise and remained at a significantly lower level during the restitution period (In T-1, after the exercise test, a significantly higher level of IGF-1 was observed after 3 h of restitution in both groups. In T-2, a significant increase after exercise was observed only in the supplemented group after 3 h of rest (
