Overview of Cardio Shield

Were you aware that heart disease and stroke rank as the leading causes of death in the United States? It might surprise you to learn that individuals with hypertension (high blood pressure) face a higher risk of developing these conditions.

According to the Centers for Disease Control and Prevention [1], hypertension contributed to over 670,000 fatalities in the US in 2020. So, what can be done? While lifestyle changes can make a significant impact, there are instances where additional support can be beneficial.

That’s where blood support supplements come into play. Our editorial team recently discovered one such supplement called Cardio Shield, which aims to address the underlying causes of hypertension in the body. If you’re interested, here’s everything you need to know about this highly acclaimed product.

What Is Cardio Shield?

Cardio Shield presents an all-natural blood pressure formula that specifically targets the root cause of high blood pressure. According to Jerry, the creator, each serving of Cardio Shield has the potential to improve healthy blood flow, reduce blood pressure, and lower the risk of cardiovascular disease. The underlying issue revolves around blood vessels constricting, resulting in increased pressure within them.

This constriction might lead to decreased nitric oxide levels in the body, making it difficult for individuals to witness favourable changes in their blood readings. Our editorial team was particularly intrigued by the idea that this “rogue” molecule could be a major culprit behind readings higher than 120/80 mmHg. Let’s delve deeper into the details of this problematic molecule and how Cardio Shield serves as a protective measure against it.

How Does Cardio Shield Work?

Cardio Shield is designed to counteract the actions of a harmful molecule known as superoxide anion [2], a free radical that can lead to oxidative stress and damage vital biomolecules, including DNA, potentially weakening blood vessels.

According to Jerry, the creator, an imbalance between superoxide anion and nitric oxide can result in peroxynitrite [3], which is crucial for combating pathogens but can be detrimental when not balanced.

We discovered a study [4] supporting the link between superoxide anion production and hypertension, suggesting it may play a role in cardiovascular risk factors.

Jerry and his team have identified five essential nutrients that aim to restore nitric oxide levels and counter the effects of harmful molecules like superoxide anion, potentially helping individuals regain control over their blood pressure levels. Let’s delve into these five nutrients and their potential benefits.

Cardio Shield Ingredients – Are They Safe & Effective?

Cardio Shield features a proprietary blend of meticulously chosen ingredients known for their potential heart health benefits, the key ingredients are:

Hawthorn Leaf Extract

Hawthorn Leaf Extract

Hawthorn is a flowering, thorny tree, or shrub of the rose family. This antioxidant-rich herb [5] has been shown to benefit a variety of health conditions. In terms of high blood pressure, it may lower resting diastolic blood pressure in mildly hypertensive people. Another study discovered that a daily consumption of 1200mg lowered blood pressure and blood sugar levels; nevertheless, further evidence is required due to the inconsistent results of previous comparable studies.

A source that explored the use of hawthorn supported a probable method through which the herb could assist with blood pressure [6]. The author specifically described its role as a vasodilator, relaxing constricted blood vessels (thereby lowering blood pressure). Additionally, hawthorn intake may lower total and bad cholesterol levels, limiting plaque accumulation in blood vessels, consequently, reducing the risk of a heart attack or stroke, as we discussed in our review of another blood pressure supplement called Bazopril.

Hibiscus Flower

Hibiscus Flower

Hibiscus is a plant that is native to India and Malaysia. It has historically been used for culinary, cosmetic, and medicinal uses. In terms of health, this ingredient is high in vitamin C, flavonoids, and anthocyanins, all of which have antioxidant characteristics [7] that help protect the body from free radicals (like the superoxide anion).

As previously stated in this review, the latter induces oxidative stress, which is recognized to be a risk factor for high blood pressure, diabetes, heart disease, and cancer. Concerning blood pressure, numerous human trials have shown that drinking hibiscus beverages or taking hibiscus supplements can dramatically lower blood pressure [8], while others have acknowledged its overall comparability to prescription medications. As encouraging as the latter assertion may be, additional research is required to confirm it. The general consensus is that hibiscus acts as a vasodilator, which might explain the positive results discovered in other studies.

Olive leaf extract

Olive leaf extract

Olive leaves are a common food and medication in the Mediterranean region. This is not surprising given that they contain two essential polyphenols [9] (oleacein and oleuropein), both of which may protect against illnesses such as heart disease and cancer. A dose of anywhere between 136mg and 500mg has been demonstrated to help reduce blood pressure levels [10] (namely among those with stage 1 hypertension). Other reported benefits include lowered levels of total cholesterol, bad cholesterol, and inflammation.
Olive leaf extract has shown promising effects in supporting healthy blood pressure levels. Studies suggest that the active compounds in olive leaf extract, such as oleacein and oleuropein, may help relax blood vessels and improve endothelial function. By promoting vasodilation and reducing inflammation, olive leaf extract can contribute to lower blood pressure levels, both systolic and diastolic.

Green tea extract

Green tea extract

Green tea extract is derived from the Camellia sinensis plant. Although it is generally advised for weight loss and healthy digestion, it may also have a role in heart health. Green tea has the ability to lower systolic and diastolic blood pressure levels in the short term, according to a systematic evaluation of 24 trials [11] and 1,697 participants. However, whether the same holds true in the long run is unclear, necessitating further research. Another source that analyzed the benefits of green tea mentioned how the extract could lower blood fat levels, potentially lowering the risk of heart disease. Green tea has a great many benefits and some of them you can learn by reading this article.



Finally, there’s garlic, a spice with various therapeutic characteristics said to enhance overall health. One review [12] and meta-analysis of garlic’s effects on blood pressure levels in hypertensive participants described its ability to lower systolic and diastolic blood pressures and lower a relative percentage of risk of developing cardiovascular events. Although several studies agree on this point, more research is needed to grasp the underlying mechanism fully.

Overall, the ingredients in Cardio Shield appear to offer potential benefits for blood pressure and cardiovascular health. However, it’s essential to keep in mind that individual responses to supplements can vary, and additional research is needed to validate some of the reported effects. Before starting any new supplement, including Cardio Shield, it’s crucial to consult with a healthcare professional to ensure it is safe and suitable for your specific health needs and conditions.

What Do the Cardio Shield Reviews Say?

Conversely, reviews on official websites may be curated or moderated, potentially leading to a selection bias and only showcasing positive feedback. By exploring Amazon reviews, consumers can make more informed decisions based on real-life experiences and a broader representation of customer satisfaction.

One positive review from Nancy C states

I can’t believe the positive impact Cardio Shield has had on my health! After struggling with high blood pressure for years, I decided to give this supplement a try, and I’m so glad I did. Within a few weeks of taking Cardio Shield, my blood pressure readings started to improve significantly. Not only that, but I also feel more energetic and focused throughout the day. The natural ingredients in this product make me feel confident about what I’m putting into my body. I highly recommend Cardio Shield to anyone looking for a safe and effective way to support their cardiovascular health.

One more review says

I decided to try Cardio Shield based on the positive reviews I read, and while it did show some improvement in my blood pressure levels, I can’t say it was a dramatic change. I’ve been taking it consistently for a few months now, and my blood pressure readings have improved slightly, but not as much as I had hoped for. The supplement is easy to take and hasn’t caused any side effects, which is a plus. However, I’m not entirely convinced that it’s worth the price for the modest results I’ve experienced so far. I will continue using it for a bit longer to see if the effects become more noticeable, but for now, I’m a bit undecided on whether I’ll repurchase. We approve of these reviews because they show an overall picture of how Cardio Shield works.

How effective Cardio Shield is?

We have many case studies that shows the effectiveness of Cardio Shield. One of our cases, Robert Backer says

“I’m extremely impressed with Cardio Shield and its remarkable results. As someone with a family history of heart issues, I’ve always been concerned about my blood pressure levels.

Since I started taking Cardio Shield, my blood pressure readings have been consistently within a healthy range. I love that this supplement uses natural ingredients like hawthorn, hibiscus, and garlic, which have a long history of supporting heart health.

Additionally, the fact that it’s free from harmful additives or fillers is a huge plus for me. Cardio Shield has become an essential part of my daily routine, and I can’t thank the creators enough for this fantastic product.”

Cardio Shield Review – Conclusion

In conclusion, Cardio Shield appears to be a promising supplement with a blend of natural ingredients that have the potential to support cardiovascular health and blood pressure management. Many five-star reviews highlight significant improvements in blood pressure readings, increased energy, and overall well-being after using Cardio Shield. Users appreciate the use of well-known herbal extracts like hawthorn, hibiscus, and garlic, which have been traditionally associated with heart health benefits.

However, it’s essential to acknowledge that individual responses to supplements can vary, as seen in the three-star review where the results were not as dramatic as expected for one user. While Cardio Shield may work well for some, it may not have the same level of impact for others. As with any supplement, individual factors, lifestyle choices, and health conditions can influence the outcomes.

Overall, Cardio Shield’s blend of ingredients shows potential in supporting blood pressure and cardiovascular health. Nevertheless, before starting any new supplement, it’s crucial to consult with a healthcare professional to ensure it is safe and suitable for individual needs and to set realistic expectations. By combining Cardio Shield with a balanced diet and healthy lifestyle choices, individuals can take proactive steps toward supporting their heart health and overall well-being.
