Our Formula
Over 105 Studies Backing Our Formula
Most people end up having to take at least one blood pressure or heart supplement.
Cardiovascular diseases, including, stroke, heart attack, and coronary artery disease are the leading cause of death in the United States.
In fact, one person dies every 33 seconds from a CVD.
This costs the US government over $240 billion, and the average spent in drugs for patients is $220!
On top of that, many drugs has side effects like migraines, nausea, fatigue, or dizziness. They are no fun to take.
What they don't tell you is that most of the drugs for blood pressure and heart are based on natural ingredients. They take the properties of herbs and plants, and make synthetic copies to sell them to you.
Natural ingredients are as good as synthetic counterparts if used correctly. Don't take it from us, take it from the experts:
Research has proven that a daily inorganic nitrate dose can be as effective as medical intervention in reducing blood pressure and the best part is we can get it from beetroot! Dr A. Ahluwalia.

Vitamin C (250mg)
Vitamin C is known for its antioxidant properties, which can help reduce oxidative stress and inflammation, both of which are associated with cardiovascular diseases.
Studies have shown that vitamin C supplementation may help in reducing the risk of cardiovascular disease by inhibiting low-density lipoprotein cholesterol oxidation, modifying platelet activity, and reducing thrombotic potential (1).
Additionally, high doses of vitamin C have been associated with a reduction in coronary heart disease risk, as evidenced by a pooled analysis of nine cohorts.
Why 250mg?
Even though the RI of Vitamin C is 90mg for men and 70mg for women, higher doses have been used to manage hypertension and see the maximum effects. With 250mg, you will get a safe but efficient boost to your vitamin C intake that will help you manage blood pressure.
Magnesium Glycinate (200mg)
Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, blood glucose control, and blood pressure regulation. Magnesium glycinate, a form of magnesium combined with glycine (an amino acid), is particularly noted for its high bioavailability and gentle effect on the stomach, making it a preferred choice for supplementation.
- Vasodilation: Magnesium helps relax the blood vessels' smooth muscles, facilitating vasodilation (widening of blood vessels) which can lead to a reduction in blood pressure. This relaxation of the vascular smooth muscle reduces peripheral resistance, a key factor in hypertension management.
- Calcium Channel Blockade: Magnesium acts similarly to calcium channel blocker drugs. It competes with calcium for binding spots in the heart and blood vessels, leading to relaxation and lowered blood pressure.
- Improvement in Endothelial Function: Magnesium is critical for the health of the endothelium (the lining of the blood vessels). It supports the production of nitric oxide, a molecule that helps blood vessels relax and dilate properly.
- Electrolyte Balance: Magnesium works in concert with other electrolytes, such as potassium and calcium, which are crucial for maintaining healthy blood pressure levels. An appropriate balance of these electrolytes is vital for heart health and blood pressure regulation.
Why 200mg?
Even though, research suggests that doses ranging from 500 mg to 1,000 mg of magnesium per day can be effective for improving blood pressure, studies have shown that taking 300mg is enough (2).
Given that magnesium glycinate is a highly absorbable form of magnesium, 200mg should be enough for most people. On top of that, having too much magnesium can cause problems to people with kidney damage or counteract with certain medications.
Vitamin B6 (50mg)
Low serum vitamin B6 is associated with hypertension in humans.
Vitamin B6 and B2 are essential for cardiovascular health as they are involved in homocysteine metabolism. Elevated levels of homocysteine are associated with an increased risk of cardiovascular diseases. Vitamin B6 and B2 are known to help lower homocysteine levels, thus potentially reducing the risk of cardiovascular issues.
It can also act in the following ways:
- Sympathetic Nervous System Regulation: Some research suggests that vitamin B6 may influence the sympathetic nervous system, which controls blood pressure among other functions. Although the mechanism is not fully understood, B6 might help in reducing blood pressure by modulating this system.
- Inflammation Reduction: Vitamin B6 has been associated with reducing inflammation markers in the body. Since inflammation can contribute to increased blood pressure and vascular damage, B6 offers protective cardiovascular effects.
Why 50mg?
Recommended intake is 1.5mg of vitamin B6. However, high doses of Vitamin B6 have been proven to lower blood pressure. Research suggests that 50mg can be enough (3).
Vitamin B2 (1mg)
Vitamin B2, or riboflavin, is particularly important for those with a MTHFR 677TT genotype. This mutation is linked with higher chance of hypertension and issues regulating blood pressure. Research has shown that for people with the MTHFR 677TT genotype, which affects folate metabolism, vitamin B2 supplementation can significantly lower blood pressure. This is due to riboflavin's role in the MTHFR pathway, where it helps to normalize homocysteine levels.
Endothelial Function: Though the research is more limited, there's some indication that vitamin B2 can improve endothelial function, which is vital for regulating blood vessel dilation and, consequently, blood pressure.
Why 1mg?
The benefits of vitamin B2 are significant even at low levels. With 1mg you will be reaching the daily recommended dose (4).
Folate (2,500mcg)
Folate, or vitamin B9, is vital for cardiovascular health. Folate supplementation has been linked to a reduced risk of stroke and cardiovascular disease (5). It plays a role in the metabolism of homocysteine, and higher levels of folate have been associated with a lower risk of cardiovascular diseases.
- Homocysteine Regulation: Similar to vitamin B6, folate plays a pivotal role in metabolizing homocysteine, a non-protein amino acid. High levels of homocysteine in the blood are linked to an increased risk of cardiovascular diseases, including hypertension. Folate helps convert homocysteine into methionine, a beneficial amino acid, thereby potentially lowering the risk of developing high blood pressure and other cardiovascular conditions.
- Endothelial Function: Folate is essential for the production of nitric oxide, a molecule that helps maintain the dilation of blood vessels, ensuring proper blood flow and reducing blood pressure. Adequate folate intake supports endothelial health, which is crucial for blood pressure regulation.
- Blood Pressure Reduction in Pregnancy: Folate is particularly important in pregnancy, not only for preventing neural tube defects but also for reducing the risk of pregnancy-induced hypertension (preeclampsia). This showcases its role in maintaining healthy blood pressure levels under specific conditions.
Why 2,500mcg?
Although the dietary allowance is set around 400mcg, research suggest that higher intakes are beneficial to lower blood pressure, ranging from 1,000 to 5,000mcg (6).
Beetroot Extract (500mg 4:1)
Beetroot extract contains high levels of inorganic nitrate, which has been shown to have a positive impact on blood pressure regulation.
Studies have indicated that beetroot extract supplementation can lead to a reduction in blood pressure, potentially lowering the risk of cardiovascular issues.
- Dietary Nitrates: Beetroot is rich in dietary nitrates, which the body converts into nitric oxide. Nitric oxide is a potent vasodilator, meaning it helps to relax and widen the blood vessels, improving blood flow and thereby reducing blood pressure. This mechanism is crucial for managing hypertension and improving overall cardiovascular health.
- Endothelial Function: The improved nitric oxide production not only aids in vasodilation but also enhances endothelial function. The endothelium is the inner lining of blood vessels, and its health is vital for maintaining vascular tone and blood pressure. By supporting endothelial function, beetroot extract contributes to more effective blood pressure regulation.
- Oxidative Stress Reduction: Beetroot has antioxidant properties that help reduce oxidative stress in the body. Oxidative stress is a condition characterized by an imbalance between free radicals and antioxidants, which can lead to inflammation and vascular damage, contributing to hypertension. By combating oxidative stress, beetroot extract can help protect the cardiovascular system.
Why 500mg 4:1 Extract?
Many supplements don't provide you with enough nitrate, as the beetroot is not concentrated enough. Doses between 100-500mg have been shown to lower systolic blood pressure (7).
Proprietary Blend (Garlic Powder, Ginger Extract, Greeen Tea) 650mg
Why Garlic?
Garlic is known for its potential to lower blood pressure and reduce cholesterol levels, thus contributing to cardiovascular health. Allicin, a key component of garlic, has been associated with vasodilation and antiplatelet effects, which are beneficial for cardiovascular function.
- Vasodilation: Garlic contains compounds that can stimulate the production of nitric oxide in the body, which helps relax and dilate blood vessels. This process reduces peripheral resistance and lowers blood pressure. The vasodilatory effect of garlic is central to its blood pressure-lowering properties.
- Angiotensin-Converting Enzyme (ACE) Inhibition: Some studies suggest that garlic acts similarly to ACE inhibitor drugs, which are commonly prescribed to treat hypertension. Garlic may inhibit the activity of the angiotensin-converting enzyme, thereby preventing the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This action helps lower blood pressure by preventing the narrowing of blood vessels.
- Allicin and Other Sulfur-Containing Compounds: The primary active component in garlic, allicin, and other related sulfur-containing compounds, are believed to be responsible for many of its cardiovascular benefits. These compounds can help improve arterial health, reduce arterial stiffness, and lower levels of certain blood fats, contributing to better blood pressure control.
- Antioxidant Effects: Garlic has antioxidant properties that can help reduce oxidative stress, a factor that contributes to the development of hypertension. By combating oxidative damage in the cardiovascular system, garlic can support overall heart health and blood pressure regulation.
Why Ginger Extract?
Ginger has been linked to various cardiovascular benefits, including its potential to lower blood pressure (9), reduce cholesterol levels, and improve blood circulation. Studies have suggested that ginger may have anti-inflammatory and antioxidant properties that could contribute to cardiovascular health.
Vasodilation: Ginger contains compounds like gingerols and shogaols, which have been found to induce vasodilation. They help relax the smooth muscles surrounding the blood vessels, leading to a decrease in overall blood pressure. This effect can improve blood circulation and reduce the workload on the heart.
- Angiotensin-Converting Enzyme (ACE) Inhibition: Similar to garlic, ginger may also have a natural ACE inhibitory effect. By blocking the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, ginger can help lower blood pressure. This mechanism mirrors that of certain pharmaceutical ACE inhibitors used to manage hypertension.
- Anti-Inflammatory Properties: Chronic inflammation is a known risk factor for the development of hypertension and cardiovascular diseases. Ginger possesses potent anti-inflammatory properties that can help reduce vascular inflammation, thereby potentially improving blood pressure and overall cardiovascular health.
- Antioxidant Effects: The antioxidant properties of ginger can combat oxidative stress within the cardiovascular system. Oxidative stress contributes to the development and progression of hypertension by damaging blood vessels and impairing endothelial function. By reducing oxidative stress, ginger supports healthier blood pressure levels.
Why Green Tea?
Green tea is rich in catechins, particularly epigallocatechin gallate (EGCG), which has been linked to various cardiovascular benefits. Green tea consumption has been associated with a lower risk of cardiovascular diseases, including a reduction in the risk of developing hypertension, stroke, and coronary artery disease (13).
- Catechins and Polyphenols: Green tea is rich in catechins, a type of antioxidant polyphenol. The most studied catechin in green tea, epigallocatechin gallate (EGCG), has been shown to improve blood vessel function and increase nitric oxide production, leading to vasodilation and lower blood pressure (14).
- Endothelial Function: The antioxidants in green tea can help improve the function of the endothelium, the inner lining of blood vessels. A healthy endothelium is crucial for regulating blood pressure, as it controls the dilation and constriction of blood vessels in response to bodily needs.
- Reduction in Oxidative Stress: By reducing oxidative stress in the body, green tea helps protect blood vessels from damage. Oxidative stress is a key factor in the development of hypertension and related cardiovascular diseases.
- Anti-inflammatory Effects: Green tea has anti-inflammatory properties that can help reduce inflammation in the body, including the cardiovascular system. Chronic inflammation is associated with increased risk of high blood pressure.
Hibiscus (500mg)
Hibiscus has been associated with blood pressure-lowering effects. Research has shown that hibiscus supplementation may help in reducing both systolic and diastolic blood pressure, thus supporting cardiovascular health in people with hypertension (10).
- ACE Inhibition: Hibiscus has been found to have natural ACE (Angiotensin-Converting Enzyme) inhibitory effects, similar to some medications used to lower high blood pressure. By inhibiting this enzyme, hibiscus can help prevent the narrowing of blood vessels, thereby lowering blood pressure.
- Diuretic Effect: Hibiscus may exert a mild diuretic effect, helping to rid the body of excess sodium and fluid. This can lower the volume of blood that the heart must pump, reducing blood pressure.
- Antioxidant Properties: Hibiscus is rich in antioxidants, including anthocyanins, which can help reduce oxidative stress and inflammation in the body. Oxidative stress and inflammation are associated with increased blood pressure and cardiovascular risk.
- Vasodilation: The bioactive compounds in hibiscus can help improve endothelial function, leading to the dilation of blood vessels. This vasodilation contributes to lowering blood pressure by allowing blood to flow more freely.
Why 500mg?
Research has often used doses equivalent to approximately 100-500 mg of hibiscus extract daily, adjusted to reflect the anthocyanin content to maximize results.
Olive Leaf (500mg)
Olive leaf extract contains compounds that have been shown to have antioxidant, anti-inflammatory, and blood pressure-lowering effects.
- Oleuropein and Other Polyphenols: Olive leaf contains oleuropein and other polyphenolic compounds that have been identified as potent antioxidants and anti-inflammatory agents. These compounds can help improve heart health by reducing oxidative stress and inflammation in the body, factors that contribute to high blood pressure.
- Vasodilation: The bioactive compounds in olive leaf, particularly oleuropein, have been shown to promote vasodilation. They do this by increasing the production of nitric oxide, a molecule that helps relax and widen blood vessels, thereby lowering blood pressure.
- ACE Inhibition: Similar to some blood pressure medications, olive leaf extract exhibits natural ACE (Angiotensin-Converting Enzyme) inhibitory activity. By inhibiting ACE, olive leaf can help prevent the constriction of blood vessels, contributing to lower blood pressure levels.
- Improved Arterial Health: Olive leaf extract has been associated with improved arterial elasticity and decreased arterial stiffness. Healthy, elastic arteries can better adapt to blood flow, which helps maintain normal blood pressure levels.
Why 500mg?
Studies have found that this dosage range can significantly reduce both systolic and diastolic blood pressure in individuals with prehypertension or stage 1 hypertension (11).
However, benefits on blood pressure are typically observed after several weeks of consistent supplementation. Long-term adherence to supplementation, as part of a comprehensive lifestyle approach, is often necessary for sustained blood pressure management.
Hawthorn (160mg)
Hawthorn has been traditionally used for cardiovascular conditions. Research suggests that hawthorn supplementation may help in improving heart function, reducing blood pressure, and enhancing blood flow to the heart.
- Vasodilation: Hawthorn extract can help to dilate blood vessels, primarily through increasing the production of nitric oxide, a molecule that signals the blood vessels to relax and expand. This effect can lead to a reduction in blood pressure by allowing blood to flow more easily through the vessels.
- Antioxidant Properties: Hawthorn is rich in antioxidants, including flavonoids and oligomeric proanthocyanidins (OPCs), which can help reduce oxidative stress in the cardiovascular system. By combating oxidative damage, hawthorn supports healthier blood vessel function, which is beneficial for blood pressure control.
- Improved Cardiac Output: Some studies suggest that hawthorn can enhance heart muscle contraction, leading to an improved cardiac output. While this effect is more directly related to heart health and efficiency, it can indirectly influence blood pressure levels by ensuring effective blood circulation.
- Reduced Arterial Stiffness: Hawthorn may contribute to reduced arterial stiffness, a condition associated with hypertension. By improving the elasticity of the arterial walls, hawthorn helps maintain normal blood pressure levels and supports overall cardiovascular health.
Why 160mg?
Research has shown that doses as low as 160mg are effective to lower blood pressure, even though they can go as high as 1g 3x a day (12).
Coenzyme Q10 (30mg)
Coenzyme Q10 (CoQ10) is involved in energy production in cells and has antioxidant properties.
Studies suggest that CoQ10 supplementation may benefit cardiovascular health by improving endothelial function, reducing oxidative stress, and supporting overall heart function.
In one study researchers concluded that CoQ10 has the potential to lower systolic blood pressure by up to 17 mm Hg and diastolic blood pressure by 10 mm Hg, without significant side effects.
Why 30mg?
The optimal intake of CoQ10 for BP regulation in patients with cardiometabolic disorders is unknown, and its effect on circulating CoQ10 is also unclear.
While there's research that suggests higher doses could be optimal, 30mg is within the daily recommended doses. We will stay on the lookout for future advances to decided whether to increase the amount of CoQ10 or not.
