Vitamin C reduces cholesterol levels
Effect of Using Vitamin C Supplementation on Performance, Blood Parameters, Carcass Characteristics and Meat Quality of Broiler Chickens Under Heat Stress Condition: A Meta-Analysis.
We explored how vitamin C supplementation affects cholesterol levels in broiler chickens, particularly under heat stress conditions. Through a thorough meta-analysis of 35 studies conducted between 1985 and 2023, we assessed various performance metrics, including blood parameters, carcass characteristics, and overall meat quality.
Our findings revealed that vitamin C significantly reduced cholesterol levels in the broiler chickens subjected to heat stress. Specifically, the study reported a notable decrease in cholesterol concentrations, with a standard mean difference of -0.976, indicating a strong beneficial effect of vitamin C in managing high cholesterol.
Additionally, we noticed improvements in body weight and average daily gain among chickens receiving vitamin C when compared to those that did not. While vitamin C did not significantly impact feed intake or breast meat quality, it emerged as a valuable antioxidant that can help lower blood triglycerides and reduce cholesterol, thus promoting better overall health and growth in broilers during stressful conditions.
Ultimately, this meta-analysis supports the use of vitamin C at a recommended dosage of 250 mg/kg as an effective growth promoter and antioxidant in broiler diets under heat stress, directly influencing cholesterol management.

Vitamin C's cholesterol-lowering potential
Vitamin C and E supplementation and high intensity interval training induced changes in lipid profile and haematological variables of young males.
To explore the impact of vitamin C on high cholesterol levels, we designed a study involving 106 young male athletes. They were divided into five groups, including those who did not exercise and those who underwent high-intensity interval training (HIIT), some with added vitamin C, vitamin E, or both. Over eight weeks, we assessed changes in lipid profiles and various blood variables.
Our findings were promising for those taking vitamins C and E alongside regular exercise. Participants who supplemented with these vitamins and engaged in HIIT showed significant drops in body weight, overall fat percentage, total cholesterol, and triglycerides. Remarkably, levels of high-density lipoprotein cholesterol, often dubbed "good cholesterol," increased in all four intervention groups. This suggests a potential role for vitamin C in improving cholesterol levels, especially when paired with an active lifestyle.
However, we also noted some adverse changes—specifically, reductions in certain blood cell counts among those only doing HIIT. While the vitamin-supplemented groups did experience effective elevation in beneficial vitamin levels, the overall effects of vitamin C alone on high cholesterol were less definitive, as the benefits appeared more in combination with exercise. It's safe to say that although vitamin C shows some promise in reducing cholesterol, the strongest benefits occur when it's part of a broader healthy regimen.

Vitamin C affects cholesterol interaction
Joint effects of paraoxonase 1 rs662 polymorphism and vitamins C/E intake on coronary artery disease severity (Gensini and SYNTAX scores) and lipid profile in patients undergoing coronary angiography.
This study aimed to explore how vitamin C intake interacts with a genetic factor known as the paraoxonase (PON) 1 rs662 polymorphism in relation to cholesterol levels. We analyzed data from 428 patients who underwent coronary angiography, focusing on their dietary habits and genetic backgrounds.
We found that individuals carrying the R allele of the polymorphism, especially those with lower vitamin C intake, were more likely to have elevated levels of low-density lipoprotein cholesterol (LDL-C). In fact, higher consumption of vitamin C was linked to a lower risk of high total cholesterol and LDL-C levels. Interestingly, those with the QQ genotype, who did not carry the R allele, did not experience the same level of cholesterol concerns associated with low vitamin C intake.
It’s important to note that while vitamin C appears beneficial in managing cholesterol for some individuals, the genetic factors need to be considered as they significantly influence the outcomes. Overall, our findings suggest that vitamin C can play a role in cholesterol management, particularly for those with specific genetic predispositions, highlighting the importance of personalized nutrition based on genetic makeup.

Vitamin C lowers cholesterol in chickens
A comparative study on feeding timing and additive types of broilers in a high-temperature environment.
We observed how the timing of vitamin C (VC) supplementation could influence cholesterol levels in broiler chickens raised in a high-temperature environment. In our study, broiler chickens were given different treatments: some received VC from day one, while others only got it starting on day 22. Our findings indicated that the addition of VC from day one significantly lowered total cholesterol levels, compared to those who did not receive the supplement.
Furthermore, we noticed additional benefits with VC, including improved intestinal health and reduced stress indicators in the chickens. This suggests that early intervention with vitamin C could play a crucial role in managing cholesterol and overall well-being in chickens under heat stress.
Overall, our research highlights the potential of vitamin C as a dietary supplement to tackle high cholesterol in stressful conditions, providing a better understanding of its timing and effectiveness in poultry nutrition.

Frequently Asked Questions
High cholesterol, or hyperlipidemia, is a medical condition characterized by an elevated level of cholesterol in the bloodstream. Cholesterol is a waxy, fat-like substance that’s essential for building healthy cells, but too much of it can lead to serious health issues, including heart disease and stroke. Cholesterol is carried through the blood by lipoproteins, with two main types being low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL, often referred to as "bad" cholesterol, can lead to the buildup of plaque in the arteries, while HDL, known as "good" cholesterol, helps carry cholesterol away from the arteries and back to the liver.
Factors contributing to high cholesterol can include poor diet, lack of exercise, obesity, smoking, and genetic predisposition. Regular health screenings are crucial, as high cholesterol often presents no overt symptoms. Maintaining a heart-healthy diet rich in fruits, vegetables, whole grains, and healthy fats, coupled with regular physical activity and avoiding tobacco, can help manage cholesterol levels effectively. In some cases, medications may be necessary to control high cholesterol, so consulting with a healthcare provider is key for tailored advice.
Green tea extract is a concentrated form of green tea that typically contains high levels of beneficial compounds known as polyphenols, particularly catechins. These antioxidants are responsible for many of the health benefits associated with green tea, including improved metabolism, enhanced fat burning, and overall supportive effects on cardiovascular health. The extract is often available in capsules or powdered form, making it a popular supplement choice for those looking to harness the plant’s potential without having to drink multiple cups of tea each day.
In addition to its antioxidant properties, green tea extract may support weight management and provide mental clarity due to its caffeine content and L-theanine, an amino acid that promotes a state of calm alertness. As with any supplement, it's important to choose a high-quality product from reputable brands to ensure purity and potency. Users should also consult with a healthcare professional prior to adding green tea extract to their regimen, particularly if they have underlying health conditions or are taking medications.
Research suggests that green tea extract may have a beneficial effect on cholesterol levels. The active compounds in green tea, particularly catechins, are believed to help lower LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol. Some studies have shown that individuals who consume green tea extract regularly may experience reductions in total cholesterol numbers, as well as improvements in the ratio of total cholesterol to HDL (high-density lipoprotein) cholesterol, also known as "good" cholesterol.
However, while the evidence is promising, it’s crucial to approach green tea extract as a complement to a healthy lifestyle rather than a standalone solution. Engaging in regular physical activity, maintaining a balanced diet low in saturated fats and sugars, and consulting with a healthcare provider about cholesterol management are essential strategies. As always, discussing the inclusion of any supplement, including green tea extract, with a medical professional is advisable to ensure it’s appropriate for your individual health needs.
Based on user reviews, it appears that the time frame for seeing results when taking this supplement for high cholesterol can vary significantly. One user reported they had been using the supplement for about a year and noticed their cholesterol levels had settled down to a level closer to normal after consistent use Read Review. This suggests that for some individuals, it may take several months of dedicated use to see meaningful changes in cholesterol levels.
However, another user shared their experience after several months of daily use but stated they noticed no impact on their weight, indicating that results may depend on individual responses and potentially other lifestyle factors Read Review. Therefore, while some users see improvements within a few months to a year, it's essential to approach these supplements with realistic expectations and consider ongoing lifestyle and dietary changes as well.
Based on the available research, vitamin C supplementation shows some promise in managing cholesterol levels, particularly in specific contexts and populations. For instance, a study focused on patients with type 2 diabetes found that supplementation with vitamin C, when combined with chromium, led to significant reductions in total cholesterol and improvements in both HDL (good cholesterol) and LDL (bad cholesterol) levels [2]. Similarly, supplementary data suggests that vitamin C can effectively lower cholesterol levels in broiler chickens experiencing heat stress, further demonstrating its role in cholesterol management in animals [1].
However, the effects of vitamin C alone on cholesterol levels can be nuanced. Research indicates that its benefits might be more pronounced when combined with factors such as exercise; one study highlighted that young male athletes who supplemented with vitamin C saw improved lipid profiles only in conjunction with high-intensity interval training [4]. It's also essential to consider genetic factors, as another study suggested that individuals with specific genetic backgrounds may experience varying outcomes in cholesterol management linked to vitamin C intake [5]. Therefore, while vitamin C appears to have potential benefits for cholesterol management, the effectiveness may depend on additional factors like concurrent supplements, lifestyle choices, and individual genetic predispositions.
Users have reported various improvements in their symptoms related to cholesterol and overall health after using the supplement. One user highlighted significant progress after a year, noting that their cholesterol levels had settled down to a point closer to normal, along with a reduction in body fat, which reflects a positive response to the product Read Review. Additionally, another user mentioned that the supplement provided antioxidant protection and contributed to maintaining good physical shape during the off-season, reinforcing its benefits beyond just cholesterol management Read Review.
Conversely, individual results can vary. A user reported no noticeable impact on their weight after several months of consistent use, indicating that while some may experience benefits, others may not see the same outcomes Read Review. It’s essential for users to keep in mind that factors such as diet, exercise, and individual metabolism can influence the effectiveness of these supplements.
