Vitamin C, also known as ascorbic acid, is an essential vitamin that must be consumed in the diet. It plays a crucial role in immune function and is commonly used to prevent and treat the common cold. While vitamin C is readily taken up by muscle tissue, it is found in low concentrations in skeletal muscle, leaving its role in muscle soreness and repair uncertain. Some studies suggest that prolonged vitamin C supplementation may reduce muscle soreness and oxidative stress, particularly when combined with vitamin E. However, other research indicates that vitamin C supplementation has no significant impact on muscle damage markers or overall muscle recovery and function. As such, the potential benefits of vitamin C for muscle soreness remain a topic of interest in sports and exercise science.

Vitamin C supplementation may reduce muscle soreness after exercise
Vitamin C, also known as ascorbic acid, is an essential vitamin that must be consumed in the diet. It plays a crucial role in immune function and is required for the body to develop and function properly. While it is commonly recommended to obtain vitamin C from dietary sources such as fresh fruits and vegetables, particularly citrus fruits, supplementation has been explored for its potential benefits in various areas, including muscle soreness after exercise.
Vitamin C supplementation has been a topic of interest in sports and exercise science, particularly regarding its potential effects on muscle soreness, muscle damage, oxidative stress, and recovery following exercise. Several studies have been conducted to evaluate the impact of vitamin C supplementation on these aspects.
Research suggests that vitamin C supplementation may offer modest benefits in reducing muscle soreness immediately after exercise, especially with prolonged use. However, it is important to note that the effects on muscle soreness are not significant in all cases and may vary depending on the individual and the specific exercise regimen. The combination of vitamins C and E has been explored as a potential approach to enhance these benefits, as they work together to reduce oxidative stress and inflammation.
One study found that vitamin C pretreatment significantly reduced muscle soreness in the first 24 hours after eccentric exercise, suggesting a potential role for vitamin C in reducing initial muscle soreness. However, it is important to note that this study had a small sample size, and further research is needed to confirm these findings.
While vitamin C supplementation may provide some relief from muscle soreness, it is important to understand that it does not significantly impact muscle damage markers or enhance overall muscle recovery and function. Therefore, while it may help alleviate soreness, it will not improve muscle performance or repair capabilities. Overall, vitamin C supplementation may offer some benefits in reducing muscle soreness after exercise, but it should not be relied upon as a significant performance enhancer or recovery aid.

Vitamins C and E together may reduce oxidative stress and inflammation
Vitamin C (ascorbic acid) and vitamin E (α-tocopherol) are well-known antioxidants that play a crucial role in protecting cells from oxidative stress. Vitamin C is a water-soluble antioxidant that scavenges reactive oxygen species (ROS) and regenerates vitamin E. Vitamin E, on the other hand, is a lipid-soluble antioxidant that neutralizes lipid hydroperoxyl radicals in cell membranes.
Vitamin C has been found to be readily taken up by muscle tissue, although it is found in relatively low concentrations in skeletal muscle. Prolonged supplementation with vitamin C has shown beneficial effects on muscle soreness and oxidative stress, particularly in reducing lipid peroxidation and interleukin-6 levels. However, several studies indicate that vitamin C supplementation does not significantly affect markers of muscle damage or improve overall muscle recovery and function.
Vitamin E does not seem to favour recovery after exercises. However, it functions as an essential lipid-soluble antioxidant, scavenging hydroperoxyl radicals in the lipid milieu. Human symptoms of vitamin E deficiency suggest that its antioxidant properties play a major role in protecting erythrocyte membranes and nervous tissues.
When taken together, vitamins C and E have been shown to reduce oxidative stress and inflammatory responses. They can attenuate lipid peroxidation, interleukin-6 (IL-6), and cortisol levels, which are markers of oxidative stress and inflammation. This suggests that these vitamins can aid in faster recovery and reduced muscle damage post-exercise. However, it is important to note that the combination of vitamins C and E does not significantly reduce muscle soreness or improve muscle strength and recovery.
In a study by McCance et al., the effect of vitamin C (1000 mg/day) and vitamin E (400 IU/day) supplementation in pregnant women with type 1 diabetes was investigated. The authors found that vitamin supplementation may be beneficial in pregnant women with low antioxidant status, as it reduced the number of preterm births.

Vitamin C does not enhance muscle recovery or function
Vitamin C supplementation has been a topic of interest in sports and exercise science, particularly for its potential benefits in reducing muscle soreness and oxidative stress. However, evidence suggests that while vitamin C may offer some modest benefits in these areas, it does not significantly enhance muscle recovery or function.
Several studies have indicated that vitamin C supplementation does not substantially impact markers of muscle damage, such as creatine kinase and myoglobin. For example, Bailey et al. conducted a study where healthy young men were given vitamin C and E supplements for six weeks and then performed intermittent shuttle running. The results showed no significant difference in oxidative stress indicators, inflammation, or muscle function recovery between the vitamin supplementation and placebo groups.
Similarly, Martínez-Ferrán et al. found that professional soccer players who took vitamin C and E supplements before performing plyometric jumping and strength resistance training did not experience improved muscle recovery or function. Their levels of creatine kinase and delayed onset muscle soreness (DOMS) remained unchanged during recovery.
Vitamin C supplementation has also been shown to have potential negative effects on training adaptation. Chou et al. investigated the effects of vitamin C and E supplementation on muscle damage and inflammation in elite athletes after simulated Taekwondo matches. While the vitamin groups showed lower levels of creatine kinase and myoglobin, indicating reduced muscle cell membrane damage, there is inadequate evidence of positive effects on muscle recovery.
In conclusion, while vitamin C may provide some short-term relief from muscle soreness and oxidative stress, particularly with prolonged use, it does not significantly enhance overall muscle recovery or function. The effects of high-dose vitamin C supplementation on muscle recovery remain unclear, and there is even evidence suggesting negative impacts on training adaptation. Therefore, it is important to consult sports dietitians or healthcare professionals for personalized advice regarding supplementation, as it may be more beneficial to consume antioxidants through a balanced diet rich in fruits and vegetables.

Vitamin C is taken up by muscle tissue but found in low concentrations in skeletal muscle
Vitamin C is a water-soluble vitamin that is needed for the growth and repair of tissues in the body. It is also an antioxidant, meaning it blocks some damage caused by free radicals. Free radicals are made when the body breaks down food or when one is exposed to tobacco smoke or radiation.
Vitamin C is taken up by muscle tissue, but it is found in relatively low concentrations in skeletal muscle. This has led to uncertainty about whether it plays a significant role in this tissue. However, studies have shown that skeletal muscle ascorbate concentrations are highly responsive to changes in vitamin C intake and plasma concentrations.
One study found that after six weeks of intervention, there was a ~3.5-fold increase in mean muscle tissue ascorbate concentrations in both low- and high-dose groups. This suggests that muscle tissue has a significantly greater relative uptake of ascorbate than other cell types. Another study found that vitamin C supplementation before and after eccentric exercise reduced muscle soreness in the first 24 hours, but it did not affect muscle function or recovery.
Prolonged supplementation with Vitamin C has been shown to have some beneficial effects on muscle soreness and oxidative stress, particularly in reducing lipid peroxidation and interleukin-6 levels. However, several studies indicate that Vitamin C supplementation does not significantly affect markers of muscle damage or improve muscle function and recovery.

Vitamin C may reduce muscle injury from ischaemia reperfusion and sepsis
Vitamin C, also known as ascorbic acid, is an antioxidant that is taken up by muscle tissue. It has been shown to reduce muscle injury from ischaemia reperfusion and sepsis. Ischaemia-reperfusion injury (IRI) is caused by endothelial and subendothelial damage by neutrophil-derived oxidants. Vitamin C supplementation can reduce muscle soreness and oxidative stress markers immediately after exercise, but it does not significantly impact muscle damage markers or enhance overall muscle recovery and function.
Several studies have been conducted to investigate the effects of vitamin C on muscle soreness and damage. One study found that vitamin C supplementation before and after eccentric exercise reduced muscle soreness in the first 24 hours, but had no significant effect on muscle function or recovery. Another study in rats showed that oral vitamin C preserved muscle function and reduced tissue oedema and neutrophil infiltration after IRI.
Vitamin C has also been found to reduce ischaemia-reperfusion-induced acute lung injury in rats. In addition, it has been suggested that intravenous vitamin C may attenuate inflammation and vascular injury associated with sepsis and acute respiratory distress syndrome (ARDS). A randomized, double-blind, placebo-controlled trial was conducted to evaluate the effect of intravenous vitamin C infusion on organ failure scores and biological markers of inflammation and vascular injury in patients with sepsis and ARDS.
Overall, while vitamin C may offer some benefits in reducing muscle soreness and oxidative stress, it does not appear to significantly impact muscle damage or enhance muscle recovery. However, it may play a role in reducing muscle injury from ischaemia reperfusion and sepsis by attenuating oxidative damage and inflammation.
Further research is needed to fully understand the effects of vitamin C on muscle soreness, damage, and recovery, as well as its potential therapeutic benefits in the setting of ischaemia reperfusion and sepsis.
