Objective: In this study we aimed to evaluate the effects of casein and whey protein
supplementation on examination stress. We have investigated different parameters of
oxidative stress and immune function. Materials and Methods: The participants were divided
into three groups: control, casein and whey. Casein and whey groups were supplemented
with either casein or whey protein for 15 days. Blood samples were obtained at the
beginning of the study (Day 0), on the examination day (Day 16) and five days after the …

Objective
In this study we aimed to evaluate the effects of casein and whey protein supplementation on examination stress. We have investigated different parameters of oxidative stress and immune function.
Materials and Methods
The participants were divided into three groups: control, casein and whey. Casein and whey groups were supplemented with either casein or whey protein for 15 days. Blood samples were obtained at the beginning of the study (Day 0), on the examination day (Day 16) and five days after the examination (Day 21). Antioxidant capacity, glutathione, cortisol and cytokine levels (TNF-a, IL-6, IL-12) were measured.
Results
An increase in antioxidant capacity and glutathione levels of the participants using whey protein was observed. Whey protein supplementation did not affect cortisol levels, but participants taking whey protein showed an increase in serum TNF-a and IL-6 levels.
Conclusion
It is suggested that the use of whey protein strengthens the response to oxidative stress by increasing antioxidant capacity and glutathione levels, while supporting the immune system via cytokine release.
