Effects of Vitamin E and Coenzyme Q10 Supplementation on Oxidative Stress Parameters in Untrained Leisure Horses Subjected to Acute Moderate Exercise.

Abstract: The effects of antioxidant supplements on exercise-induced oxidative stress have not been investigated in untrained leisure horses. We investigated the effects of 14-day supplementation with vitamin E (1.8 IU/kg/day), coenzyme Q (CoQ; ubiquinone; 800 mg/day), and a combination of both (the same doses as in mono-supplementation) on the blood levels of CoQ, vitamin E, and oxidative stress parameters in untrained leisure horses subjected to acute moderate exercise. Correlations between lipid peroxidation and muscle enzyme leakage were also determined. Forty client-owned horses were included in the study, with 10 horses in each of the antioxidant and placebo (paraffin oil) groups. Blood parameters were measured before supplementation, before and immediately after exercise, and after 24 h of rest. The differences in individual parameters between blood collection times and groups were analysed with linear mixed models ( ˂ 0.05). None of the supplemented antioxidants affected vitamin E and CoQ concentrations, oxidative stress parameters, or serum muscle enzymes. Lipid peroxidation occurred in horses supplemented with placebo and CoQ but not in horses supplemented with vitamin E or the combination of both antioxidants. These results suggest that vitamin E alone or in combination with CoQ prevented lipid peroxidation in untrained leisure horses subjected to acute moderate exercise.

This study investigated the effects of vitamin E and coenzyme Q10 supplementation on levels of oxidative stress in untrained horses undergoing moderate exercise, finding that such supplementation did not produce significant changes in key health parameters, but did appear to guard against lipid peroxidation.

Supplementation and Oxidative Stress

  • The research focused on examining the reactions of untrained leisure horses to acute moderate exercise, with particular emphasis on the effects of antioxidant supplements on exercise-induced oxidative stress.
  • The antioxidants used for supplementation were vitamin E and coenzyme Q10 (CoQ), a compound also known as ubiquinone. The animals were given these either separately or in combination.

Research Design and Methodology

  • Forty horses were involved in the study. They were split into four groups of ten, with each group receiving supplementation of vitamin E, CoQ, a combination of both, or a placebo (paraffin oil).
  • The supplement doses were maintained at 1.8 IU/kg/day for vitamin E and 800 mg/day for coenzyme Q10. These doses were the same in the combined supplement group.
  • Blood samples were collected from the horses at various stages: before supplementation, before and after exercise, and after 24 hours of rest. These were then analyzed to study changes in blood parameters over time and between groups.

Findings

  • The study found that supplementation with either of the antioxidants did not result in significant changes in the horses’ blood levels of vitamin E, CoQ, oxidative stress parameters, or serum muscle enzymes.
  • However, lipid peroxidation – a process involving oxidative degradation of lipids, which can damage cells – was observed in horses that received the placebo supplement or just the CoQ.
  • In contrast, the horses that were given vitamin E alone or the combination of vitamin E and CoQ did not experience lipid peroxidation, suggesting that vitamin E supplementation, either alone or coupled with CoQ, can prevent this harmful effect in untrained leisure horses subjected to acute moderate exercise.
