Vitamin C may lower blood pressureEffect of vitamin C and hawthorn beverage formula on blood pressure and oxidative stress in heat-exposed workers: a cluster-randomized controlled trial.
Moderate relevance to cardiovascular research.
We conducted a study to evaluate the effects of a vitamin C supplement combined with a hawthorn beverage on blood pressure and oxidative stress among workers exposed to heat. This involved a 40-day cluster-randomized controlled trial where participants were split into two groups: one received the vitamin C and hawthorn drink, while the other was provided with slightly salted water.
Throughout the study, we measured blood pressure and levels of a specific oxidative stress marker at different intervals. Notably, we observed significant reductions in both systolic and diastolic blood pressure among those who consumed the vitamin C and hawthorn beverage compared to the control group. This suggests that the combination may help manage elevated blood pressure linked to heat exposure.
The findings highlight the potential role of vitamin C, especially when paired with other beneficial compounds in the hawthorn beverage, in combating oxidative stress and promoting cardiovascular health in individuals working in challenging environmental conditions.

Antioxidants show promise for FGRThe Use of Antioxidants for Cardiovascular Protection in Fetal Growth Restriction: A Systematic Review.
Lower relevance due to context
This systematic review focused on the potential effects of antioxidants, particularly vitamin C, on cardiovascular health in cases of fetal growth restriction (FGR). We assessed various studies that examined how these treatments might enhance cardiac and vascular outcomes in affected individuals.
Our exploration revealed that a majority of the studies indicated some level of cardiovascular protection following antioxidant intervention. Specifically, 71% of the studies noted improvements in at least one of the cardiac or vascular parameters in growth-restricted offspring. Vitamin C, along with other antioxidants, was highlighted as part of several approaches to reduce oxidative stress, which is known to contribute to cardiovascular issues.
However, it's essential to note that the specific impact of vitamin C alone was not extensively distinguished from its combined effects with other antioxidants. This ambiguity makes it challenging to pin down its isolated benefits.
Overall, while antioxidant treatments present a promising avenue for addressing cardiovascular deficits associated with FGR, crucial gaps in research remain, preventing us from determining the most effective strategies for clinical use.

Vitamin C may help prevent strokeCausal Effect of Macronutrient and Micronutrient Intake on Stroke: A Two-Sample Mendelian Randomization Study.
Moderate relevance to topic.
We investigated the potential protective effects of vitamin C on stroke risk, drawing on data from a robust two-sample Mendelian randomization study. This research compared genetic predictors of nutrient intake to stroke outcomes, focusing particularly on the intake of various vitamins, including vitamin C.
Our findings revealed that higher levels of vitamin C are linked to a reduced risk of cardioembolic stroke, with a noteworthy odds ratio suggesting that this vitamin could play a significant protective role. Specifically, when we looked at the statistics, the odds ratio was 0.759, indicating a promising association with stroke prevention. This evidence positions vitamin C as a potential target for public health strategies aimed at reducing stroke incidence.
However, while the results regarding vitamin C are encouraging, we must approach them with caution. The overall design of the study limits our conclusions, suggesting that while vitamin C appears beneficial, further research is necessary to fully understand its effects on cardiovascular health.

Antioxidants reduce CVD mortality riskAssociation of independent dietary antioxidant intake, and CDAI level with risks of all-cause and cardiovascular-cause death among population with cardiovascular disease.
Highly relevant to cardiovascular health.
We investigated the connection between dietary antioxidants, including vitamin E, and mortality risks in patients with cardiovascular disease (CVD). In our research with 1,395 participants, we found that higher levels of antioxidants were linked to decreased all-cause and cardiovascular-cause deaths.
Specifically, vitamins like C and E showed beneficial effects. This suggests that boosting our antioxidant intake could be a helpful strategy for improving health outcomes in those with CVD.

We investigated how long-term exposure to urban air pollution affects the recovery from ischemic stroke in mice. Our findings showed that breathing in fine particulate matter increases neuroinflammation and cardiac injury, leading to higher mortality rates after a stroke.
Interestingly, incorporating a vitamin E-rich diet helped reduce cardiac damage and lung inflammation caused by this exposure. We saw a noteworthy improvement in survival rates among mice with ischemic strokes who received the vitamin E, highlighting its potential protective effects against the dangers of urban air pollution.
