Vitamin C enhances blood clotting
We sought to understand how ascorbic acid, commonly known as vitamin C, impacts blood clotting during living donor liver transplantation (LDLT). In our study, we analyzed blood samples from 21 recipients before and after their surgeries.

We employed a well-structured approach, using rotational thromboelastography (TEG) and western blot analysis to scrutinize fibrinolysis and the functionality of specific proteins involved in clotting. Blood samples were tested in three distinct groups, one receiving vitamin C, to see its effects on clot rigidity and fibrinolysis.

Our findings revealed that ascorbic acid notably reduced fibrinolysis, which refers to the breakdown of blood clots, and improved the rigidity of the clots formed. Additionally, we observed that levels of a protein called Cbl-b were higher in those receiving vitamin C, while another protein, c-Cbl, showed reduced phosphorylation. These functional changes might explain how vitamin C supports better clotting during surgeries.

This study indicates that vitamin C could be a beneficial treatment to consider during LDLT to manage hyperfibrinolysis, thus promoting better outcomes for patients undergoing these complex procedures.

Scurvy-related DVT treated with vitamin C
We explored a unique case of a 14-year-old boy with autism who presented with deep vein thrombosis (DVT) due to large bilateral subperiosteal hematomas caused by vitamin C deficiency, known as scurvy. This rare situation is noteworthy as scurvy is typically associated with other symptoms, but here it led to an unusual complication of DVT.

During our investigation, we observed that after administering vitamin C replacement, the patient's condition improved significantly. Follow-up imaging showed that both the DVT and the hematomas resolved. This outcome suggests that vitamin C can potentially have a positive impact in cases where blood clots are related to underlying deficiencies.

However, we must clarify that while vitamin C treatment appeared beneficial in this specific situation, our findings are based on a single case. Thus, further research would be essential to understand its broader implications on DVT treatment and the role of vitamin C in blood clot scenarios.

Vitamin C reduces clotting factors
We explored how vitamin C influences blood clotting in response to inflammation, specifically focusing on how it affects certain proteins involved in this process. In our study, we tested vitamin C at clinically relevant doses within human monocyte-derived macrophages. This investigation involved examining its effects on tissue factor (TF) and Factor VII Activating Protease (FSAP), two key proteins that play a role in triggering blood clotting after exposure to lipopolysaccharide (LPS), which is often associated with infection and inflammation.

Our findings showed that vitamin C can prevent the activation of a protein called NF-kB, which is crucial for the inflammatory response. It turns out that vitamin C not only reduces the DNA-binding activity of NF-kB but also decreases the expression of TF and FSAP, suggesting it can effectively modulate clots formed in response to inflammation. Overall, we observed that vitamin C offers promising benefits in altering pro-inflammatory and pro-coagulation processes.

This means that aside from being a potent antioxidant, vitamin C might also support cardiovascular health by reducing the risk factors associated with clot formation during inflammatory responses. While more research is needed to validate these effects fully, our study opens the door to the potential role of vitamin C in managing clot-related disorders linked to inflammation.

Stable vitamin C levels
A really good, high-dose, instant-release vitamin C. If I wasn't now taking sustained-release vitamin C, I would still be using this one. Vitamin C is water soluble and excreted from the body within 2 - 3 hours. It’s questionable whether the entire 1000mg of the tablet gets absorbed. To maintain stable levels in my blood throughout the day, I suggest taking them more frequently and perhaps splitting them in half. I take vitamin C for its potential to lower cortisol and its immune-boosting properties, which I need to keep stable. For anyone else, these are probably great; I even give them to my daughter who is young and healthier than me.

In our investigation, we looked at how vitamin C, in combination with a fibrin clot, influences the healing of Achilles tendon injuries in rats. We used 52 adult Wistar-Albino rats and divided them into four distinct groups to assess various treatments.

The results showed that vitamin C, when paired with fibrin clot, significantly improved tendon healing. Not only did it enhance the mechanical strength of the tendon, but it also led to better histological and biochemical outcomes, suggesting a more robust healing process. We noted increased levels of important growth factors in the groups treated with fibrin clot and vitamin C.

Importantly, the findings indicated that vitamin C plays a beneficial role in recovery, especially when combined with other treatment strategies. While further research may be necessary to fully understand its isolated effects, the data suggests that vitamin C is a valuable component in the healing bundle for Achilles tendon injuries.

We explored the use of ascorbic acid, commonly known as vitamin C, as an additional treatment option for patients critically ill with COVID-19. This study was conducted across two large hospitals in Saudi Arabia and involved a thorough look at the outcomes for these patients, especially concerning blood clotting and overall health.

After evaluating 739 patients, 296 were matched for a fair comparison. Notably, the findings suggest that while there was no significant reduction in mortality rates for those receiving vitamin C compared to those who did not, the use of vitamin C was linked to a lower occurrence of thrombosis—an abnormal blood clotting condition. The incidence of thrombosis in the vitamin C group was 6.1%, compared to 13% in the non-vitamin C group, indicating a possible protective effect against blood clots.

Ultimately, while the addition of vitamin C did not show a direct mortality benefit, it may offer some hope for reducing blood clot complications in these severely affected patients. However, further research will be necessary to validate these findings and clarify the role of vitamin C in treatment protocols for COVID-19.

Frequently Asked Questions

A blood clot is a mass of blood that changes from a liquid to a gel, effectively forming a plug that can stop bleeding. This natural process, known as coagulation, is critical for preventing excessive blood loss when you sustain an injury. Blood clots can occur in various areas of the body, typically at the site of a wound, but they can also form within blood vessels without an obvious injury, which may lead to serious health complications.

While blood clots are essential for healing, they can pose significant health risks if they form inappropriately. For example, a deep vein thrombosis (DVT) occurs when a clot forms in a deep vein, usually in the legs, and can travel to the lungs, causing a life-threatening condition called a pulmonary embolism. Risk factors for blood clots include prolonged immobility, certain medical conditions, and the use of specific medications, among others. It’s important to recognize the symptoms of abnormal clotting, such as swelling, pain, and redness in the affected area, and seek medical attention if they occur.

Ascorbic acid, commonly known as vitamin C, is a water-soluble vitamin that is essential for various bodily functions, including the synthesis of collagen, the absorption of iron, and the maintenance of a healthy immune system. Found naturally in a variety of fruits and vegetables, especially citrus fruits, strawberries, kiwi, and bell peppers, it serves as a potent antioxidant, helping to protect cells from damage by free radicals. Given that the human body cannot synthesize ascorbic acid on its own, it must be obtained through diet or supplementation.

In addition to its fundamental role in supporting overall health, ascorbic acid has garnered interest for its potential benefits in skincare and wound healing. Topical applications of vitamin C can help reduce the appearance of fine lines and improve skin texture, making it a popular ingredient in various cosmetic formulations. Additionally, it plays a crucial role in the body's ability to repair tissues and produce important neurotransmitters. For those looking to boost their vitamin C intake, incorporating a variety of vitamin C-rich foods into your diet or considering a supplement can be effective strategies.

Vitamin C has emerged as a focus of research concerning its role in blood clot formation and related complications, with several studies providing compelling evidence of its effects. In critically ill COVID-19 patients, for example, a study highlighted that vitamin C use correlated with a lower incidence of thrombosis, suggesting a possible protective effect against abnormal blood clotting [2]. Other research also indicated that vitamin C influences clot rigidity and reduces fibrinolysis during live donor liver transplantation, showing its potential utility in managing hyperfibrinolysis and promoting better outcomes during these complex surgeries [4].

However, it is essential to note that not all findings are positive. Research has shown that high doses of vitamin C can increase the risk of blood clot formation, particularly in cancer patients, where elevated levels make red blood cells more prone to clotting [6]. While vitamin C also appears to modify clotting processes related to inflammation, more extensive research is necessary to clarify its benefits and risks across different patient populations [5]. Overall, while vitamin C may offer some promise in reducing blood clot complications in specific settings, caution is warranted, and its use should be tailored to the individual's health status.

Based on user reviews, many individuals have reported significant improvements in their health when using Vitamin C supplements. Notably, users have highlighted its effectiveness in strengthening the immune system, with some stating that it has helped prevent colds and reduced their severity when they do occur (Read Review). Additionally, one reviewer mentioned that Vitamin C might play a critical role in enhancing overall recovery from viral illnesses, including influenza (Read Review).

Users also appreciate the broader spectrum of benefits provided by Vitamin C, including its support in maintaining blood vessel health and promoting tissue regeneration (Read Review). A reviewer noted that their experience with high-dose, instant-release Vitamin C was positive, as they found it suitable for maintaining stable cortisol levels and immune function, suggesting that it might be useful for anyone needing consistent immune support (Read Review). However, individual results can vary widely based on personal health conditions and dosage.

Based on user reviews, there is a general consensus on the importance of appropriate dosing of Ascorbic Acid (Vitamin C) for various health benefits, including its potential role in treating conditions like blood clots. One user mentioned that it’s beneficial in maintaining capillary permeability and promoting tissue regeneration, which can be significant for those concerned with blood vessel health (Read Review).

Several users emphasized the effectiveness of vitamin C at higher doses, with one suggesting not just a single large dose but rather frequent, smaller doses to maintain stable blood levels, as vitamin C is water-soluble and eliminated quickly by the body (Read Review). This approach could be particularly relevant for managing conditions like blood clots, where consistent supplementation may enhance benefits. However, specific dosages for treating blood clots weren't detailed in the reviews, highlighting that while there is anecdotal support for vitamin C’s benefits, personalization of dosage may be essential.

Vitamin C may promote thrombosis
We examined the impact of high doses of vitamin C on blood clotting, particularly focusing on its effect on red blood cells (RBCs). Through our research, we discovered that vitamin C, when injected intravenously in doses of 0.5 to 5 mM, can increase the tendency of RBCs to become procoagulant. This increase was linked to a process where a molecule called phosphatidylserine is exposed on the outer membrane of these cells, which can lead to blood clot formation.

The molecular changes in RBCs were attributed to oxidative stress induced by high vitamin C levels, disrupting important calcium and thiol balance in the cells. Furthermore, our findings showed that administering vitamin C at 0.5 to 1.0 g/kg in rats resulted in a significant increase in thrombosis events. More importantly, RBCs from cancer patients displayed an increased sensitivity to these prothrombotic effects compared to healthy individuals.

Given these observations, it’s crucial to approach high-dose vitamin C therapy with caution, particularly in patients already at a higher risk for blood clotting. While vitamin C is often thought to have health benefits, our study reveals a potential risk that must not be overlooked.
