Oral administration of ascorbic acid to horses.

This research investigates the impact of orally administered high doses of ascorbic acid (Vitamin C) on the plasma concentrations in Thoroughbred horses. The study determined that while a one-time dose did not elevate plasma levels, consistent daily doses did show significant increases.

Overview of the Research

The research focused on the outcomes of orally given doses of ascorbic acid, commonly known as Vitamin C, in Thoroughbred horses. The major investigation areas involved whether a single dose or repeated daily administration had an effect on plasma concentrations of ascorbic acid.

• A single dose of ascorbic acid (20 g) was found not to increase plasma concentrations.
• Nonetheless, daily doses, either of 4.5 g or 20 g, led to considerable increases in plasma concentrations of ascorbic acid.

Key Findings

Chronic administration of ascorbic acid, as opposed to a one-time dose, was more effective in boosting ascorbic acid plasma concentrations. Additionally, variations in plasma concentrations were noted over different months in both supplemented and non-supplemented stables.

• Horses that received a daily dose of ascorbic acid (either 4.5 g or 20 g) showed perceptible increases in plasma concentrations of the vitamin.
• There were noticeable monthly variations in plasma ascorbate concentrations in stables that supplemented with 20 g daily and those that were not supplemented.

Conclusions Derived

The authors concluded that oral supplementation with ascorbic acid effectively increased plasma and tissue concentrations. Therefore, orally administering ascorbic acid to horses can be a viable route to increase their vitamin C plasma and tissue levels.

• According to this study, oral supplementation of ascorbic acid is an effective way to boost plasma and tissue concentrations in horses.
• It implies that using ascorbic acid supplements can be beneficial in maintaining optimum levels of vitamin C in horses, especially considering these animals experience physical exertion and oxidative stress during racing and training.
