Overview
Top Medical Research Studies
Over a span of ten weeks, we administered different doses of vitamin K2 to rabbits fed a cholesterol-rich diet.
The findings were encouraging; the vitamin K2-treated rabbits had significantly lower cholesterol levels compared to a control group.
Additionally, it seems that vitamin K2 at moderate doses helped slow down the development of atherosclerosis without any adverse effects on blood coagulation.
After 6 and 12 weeks, we found that this combination didn't significantly lower total cholesterol, LDL cholesterol, or triglycerides. It also had no impact on various inflammatory biomarkers.
Our findings indicate that, at the doses used, the nutraceutical combination did not effectively change cholesterol or inflammatory markers.
However, we found that the relationship between the changes in PCSK9 and LDL cholesterol normalized in participants taking the supplement. This suggests that while cholesterol levels remained steady, the supplement might help improve how these two important factors relate to each other in the context of statin therapy.

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.
Vitamin K is a fat-soluble vitamin crucial for various bodily functions, particularly in the clotting process of blood. It exists in two primary forms: K1 (phylloquinone), which is primarily found in leafy green vegetables like spinach and kale, and K2 (menaquinone), which is found in fermented foods and certain animal products. Vitamin K plays a significant role in the synthesis of proteins that regulate blood coagulation and is also essential for bone metabolism, assisting in the binding of calcium to bones and other tissues.
Deficiencies in vitamin K can lead to increased bleeding and bruising, and in severe cases, it may contribute to bone weakness. While most people can obtain adequate amounts of vitamin K through a balanced diet rich in vegetables and fermented foods, those with certain medical conditions or who are on specific medications may require monitoring and supplementation. Incorporating a variety of nutrient-dense foods into your diet is the best way to ensure you get enough vitamin K for optimal health.
Based on user reviews, the timeline for seeing results from taking this supplement for high cholesterol can vary significantly. While specific time frames are not commonly mentioned, users suggest that regular use can provide numerous benefits, including reductions in harmful cholesterol. One user noted that the product makes a significant impact on cholesterol levels, which reflects a positive experience with its long-term effects (Read Review). However, another user warned of variable tolerance levels, indicating that results can be different from person to person (Read Review).
Many users recommend consistent consumption for best results, as some benefits may require continued use to fully manifest. As these reviews indicate, while some individuals notice improvements, such as better cholesterol levels, right away, it’s generally advisable to give the supplement time to work effectively. Therefore, monitoring your body and consulting with a healthcare provider may provide the best insight tailored to your situation.
The effectiveness of vitamin K supplements in treating high cholesterol shows mixed results based on current scientific research. A double-blind, placebo-controlled trial examined a nutraceutical combination containing vitamin K but found no significant changes in total cholesterol, LDL cholesterol, or triglycerides in individuals with high cholesterol over 6 and 12 weeks [1]. Similarly, another study involving a combination of Octacosanol and vitamin K2, while not resulting in major changes to overall cholesterol levels, indicated some normalization in the relationship between PCSK9 and LDL cholesterol for those on atorvastatin [2].
In contrast, animal studies, specifically with rabbits, have shown more promising results for vitamin K2 in managing high cholesterol. The treatment led to significantly lower cholesterol levels and slowed the advancement of atherosclerosis without affecting blood coagulation [3]. Overall, while there's some potential shown in animal studies, the human trials suggest that vitamin K supplementation alone may not effectively improve high cholesterol levels.
Users have reported a variety of symptom improvements when using this supplement, particularly concerning high cholesterol and overall health. One user highlighted the product's efficacy in helping to reduce harmful cholesterol levels while also benefiting hair, nails, and skin (Read Review). Another reviewer described it as essential for managing cholesterol and encouraging regular use due to its numerous benefits (Read Review).
However, individual experiences do vary significantly. While many users report positive effects, one review mentioned that a user’s mother did not tolerate the supplement well, despite its effectiveness for others (Read Review). This highlights the importance of monitoring your own body’s response and consulting with a healthcare provider, especially if you experience any adverse effects. As such, while numerous anecdotal experiences testify to its benefits, potential users should proceed with caution and expectations suited to their unique situations.
Users report varying experiences when combining this supplement with other supplements for managing high cholesterol. Some highlight the necessity of pairing high doses of vitamin D3 with vitamin K2 to avoid potential issues such as vessel calcification, indicating that these combinations are essential for effective supplementation (Read Review) (Read Review). This suggests that while the cholesterol-lowering effects of the supplement are noteworthy, users often recommend a holistic approach to supplementation that considers the synergistic effects of various vitamins and nutrients.
Additionally, while several users advocate for the regular use of this supplement due to its benefits for cholesterol management and overall health (Read Review) (Read Review), experiences can vary significantly. One user mentioned that despite the positive reports, their mother did not tolerate the product well, suggesting that while many find value in combinations for effectiveness, individual responses can differ greatly (Read Review). As such, it's crucial for individuals considering this supplement to account for their unique health circumstances and possibly consult with a healthcare provider.
Users report varying effectiveness of Vitamin K for treating high cholesterol, highlighting its benefits in reducing harmful fats in the body. One user emphasized that taking Vitamin K is essential, particularly for those managing high cholesterol, and encouraged regular consumption due to its numerous health benefits (Read Review).
