We explored the effects of vitamin C on natural killer (NK) cell activity in patients with coronary artery disease (CAD). Our research involved isolating NK cells from 29 CAD patients and treating them with various stimulatory factors, including ascorbic acid—better known as vitamin C.
What we found was quite interesting: when NK cells were treated with ascorbic acid, there was a significant increase in their ability to proliferate. This meant that the NK cells were more active and potentially more effective in responding to threats in the body, which is vital for those dealing with heart conditions.
Furthermore, we measured serum lactate dehydrogenase (LDH) levels, discovering a negative correlation between LDH and NK cell activity. Higher LDH levels seemed to indicate lower proliferation capability in NK cells influenced by interleukins.
Overall, our study suggests that vitamin C could play a positive role in enhancing immune function in CAD patients by promoting NK cell proliferation. However, it's important to note that while vitamin C shows promise, further research is needed to fully understand its impact on cardiovascular health and immune regulation.

Vitamin C may help prevent stroke
Causal Effect of Macronutrient and Micronutrient Intake on Stroke: A Two-Sample Mendelian Randomization Study.
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.

Vitamin C may lower blood pressure
Effect of vitamin C and hawthorn beverage formula on blood pressure and oxidative stress in heat-exposed workers: a cluster-randomized controlled trial.
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 FGR
The Use of Antioxidants for Cardiovascular Protection in Fetal Growth Restriction: A Systematic Review.
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.

Frequently Asked Questions
Cardiovascular disease (CVD) is a broad term that encompasses a range of heart and blood vessel disorders. This can include conditions such as coronary artery disease, which leads to heart attacks; cerebrovascular disease that results in strokes; and peripheral artery disease affecting blood flow to the limbs. The key risk factors for CVD often include high blood pressure, high cholesterol, obesity, smoking, a sedentary lifestyle, and diabetes. By identifying and managing these risk factors, individuals can significantly reduce their likelihood of developing cardiovascular problems.
Prevention and treatment strategies often involve lifestyle modifications such as adopting a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, alongside engaging in regular physical activity. In some cases, medications might be necessary to control blood pressure or cholesterol levels. Regular check-ups with a healthcare provider are essential for monitoring heart health, especially for individuals with a family history of CVD. Understanding the signs and symptoms of cardiovascular issues—like chest pain, shortness of breath, or fatigue—can help in seeking timely medical attention, ultimately leading to better outcomes.
Ester-C is a patented form of vitamin C (ascorbic acid) that is known for its unique formulation, which includes calcium ascorbate. This makes Ester-C less acidic than standard vitamin C, making it gentler on the stomach for those who may experience gastrointestinal discomfort from regular vitamin C supplementation. One of the key features touted by manufacturers of Ester-C is that it is better absorbed by the body and stays in the immune system longer, although scientific research on these claims can be mixed.
In addition to its purported benefits, Ester-C is often marketed as a supplement that supports immune health, collagen production, and serves as an antioxidant, helping to combat free radicals and oxidative stress. It's available in various forms, including capsules, tablets, and powders, making it easy to incorporate into your daily routine. While some users report positive effects and tolerance of Ester-C, it's essential to consult with a healthcare professional before adding any new supplement to your regimen, especially if you have existing conditions or are taking other medications.
Recent studies suggest that vitamin C may have a supportive role in cardiovascular health, particularly in specific patient populations. One systematic review highlighted that antioxidants like vitamin C could enhance cardiac outcomes, especially in individuals affected by fetal growth restriction, with 71% of the studies showing improvements in at least one cardiovascular parameter when antioxidants were used [1]. Additionally, research indicated that vitamin C boosts the proliferation of natural killer (NK) cells in coronary artery disease patients, potentially enhancing immune function and ability to combat heart conditions [2].
Moreover, a Mendelian randomization study revealed a significant association between higher vitamin C levels and a reduced risk of cardioembolic stroke, marking it as a potential protective factor in stroke prevention [3]. Another study found that vitamin C, combined with hawthorn, led to notable reductions in both systolic and diastolic blood pressure among heat-exposed workers, suggesting its efficacy in managing blood pressure and oxidative stress [4]. These findings collectively indicate that while more research is essential to establish the exact mechanisms and benefits, vitamin C shows promise in contributing to cardiovascular health.
