Formule supérieure pour la santé cardiovasculaire
Cardiovascular health is the sum of the health of many different body functions: blood lipids, blood pressure, vascular health, heart muscle health, and electrical function, to name a few. Ortho Heart is designed to promote cardiovascular health through multiple mechanisms.Garlic extract helps to balance blood lipids and cholesterol, while L-theanine promotes relaxation, stress relief and quality sleep – all of which can have a beneficial influence on blood pressure. Chlorogenic acid from green coffee bean extract supports weight management and has been shown to help lower blood pressure. Nitric oxide improves blood vessel function and blood flow by dilating blood vessels and improving their flexibility – potassium nitrate and vitamin C support the production of this important nutrient. Lastly, studies support the ability of hibiscus to promote healthy blood pressure. This is key since high blood pressure, also known as the silent killer, tends not to produce symptoms until it is severe.Those with a family history of blood pressure or cholesterol problems, or those looking to support their heart health and blood pressure naturally can benefit from taking Ortho Heart.

BackgroundWhat Makes Up Heart Health?Cardiovascular health is the sum of the health of many different body functions: blood lipids, blood pressure, vascular health, heart muscle health, and electrical function, to name a few. These functions are affected by factors such as inflammation, metabolism, nutritional status, stress, sleep, and so much more. High blood lipids and unhealthy blood pressure levels are both silent killers since neither tends to produce symptoms until they are severe. The best way to promote cardiovascular health is to target as many of these factors as possible. The good news is that maintaining a healthy diet and lifestyle can help prevent or improve these conditions. Ortho•Heart is a formula that supports such efforts.High Blood LipidsElevated blood lipids can be characterized by high amounts of several types of lipids, including total cholesterol, LDL cholesterol, triglycerides, and lipoprotein(a), among others. About 40% of Canadian adults have high cholesterol, and this does not even include triglycerides or other blood lipid markers.Unhealthy Blood Pressure19% of Canadian adults have an unhealthy blood pressure level. Having an unhealthy blood pressure level can lead to serious health problems such as heart disease, heart attack and stroke. It has been estimated that a reduction of 5 mmHg in systolic BP could reduce stroke mortality by 14% and decrease cardiovascular disease mortality by 9%.Sleep & StressA lack of sleep can increase the risk of heart disease, and it also increases blood pressure. A 1998 survey found that about 25% of adults have trouble sleeping, and that about half of adults cut back on sleep in order to get more done, especially those that already had trouble sleeping. 40% of people that felt time-stressed had trouble sleeping. One quarter of Canadians report living a high-stress life. It is well-known that Type A personalities and high-stress individuals are more prone to heart disease.Obesity & DietA whopping 60% of adults are overweight or obese. This is both due to decreased physical activity following increased mechanization as well as consuming more high-calorie, low-nutrient foods. A higher body weight is directly related to an unhealthy blood pressure level. More body mass requires more oxygen, which requires an increased blood volume, all of which exerts pressure on the blood vessels and makes the heart work harder.Ortho•Heart IngredientsThe ingredients found in Ortho•Heart help target all of the heart health factors above.GarlicGarlic is traditionally used in herbal medicine to help lower blood lipids.L-TheanineL-Theanine is an amino acid found in green tea that is known to reduce stress and promote a relaxed alertness by increasing alpha brainwaves. This kind of state directly precedes stage 1 sleep. Two animal studies have also found blood pressure modulation in rats supplemented with L-Theanine. L-Theanine also indirectly increases the production of GABA, a key inhibitory neurotransmitter in the brain. It is well known for its anti-anxiety effects, but is less often recognized for its effectiveness as a blood pressure modulating agent. Furthermore, certain blood pressure regulating drugs have been shown to increase GABA levels in the hypothalamus, highlighting the importance of this neurotransmitter in the regulation of blood pressure. GABA appears to induce blood vessel relaxation, resulting in a more healthy blood pressure level.Green Coffee Bean Extract (Chlorogenic Acid)Green (unroasted) coffee bean extract rich in chlorogenic acid, a dietary phenol, has recently been discovered to have cholesterol-reducing, blood pressure regulating, and weight reduction effects.Nitrates, Nitric Oxide & Vitamin C|More than half of Canadians over the age of 12 consume less than half the recommended daily servings (<5) of fruits and vegetables. The most dramatic blood pressure lowering effects have been associated with dark leafy vegetables, like beetroot, spinach and lettuce, which are high in nitrate content. Nitrates are converted by the body into nitrites, which are then converted into nitric oxide (NO). NO is a very important molecule in the body, and is vital for the proper functioning of the cardiovascular system. Primarily it is a potent vasodilator, meaning that it widens the blood vessels, thereby reducing blood pressure. Furthermore, NO helps to improve blood vessel elasticity, improve the function of the cells lining the blood vessels (endothelial cells), prevent blood vessel inflammation and inhibit platelet aggregation.Platelet aggregation and endothelial cell dysfunction in the blood vessels can lead to arterial plaque build-up and clot formation, which can impede the flow of blood through the arteries, leading to an increase in blood pressure, as well as other dangerous outcomes, such as heart attack or stroke. Since nitrates act to reduce platelet aggregation, improve endothelial cell function, and promote vasodilation, they modulate blood pressure and improve overall cardiovascular health.Ortho•Heart includes not only potassium nitrate as a direct source of nitrates, but also a proprietary nitric oxide generating veggie powder, to maximize NO production and stabilize blood pressure level. The formula also includes vitamin C, which has been shown to help ensure the effectiveness of nitrate supplementation. Over time, supplementation with nitrates can become less effective, a condition called nitrate tolerance. However, research has shown that co-supplementation with vitamin C prevents tolerance from developing. Vitamin C has the additional benefit of being a powerful antioxidant, thereby having cardiovascular benefits in its own right. Vitamin C also helps with collagen production, which is important for vascular health.HibiscusHibiscus sabdariffa is an edible medicinal plant, indigenous to India, China and Thailand and is used in Ayurveda and traditional medicine. Hibiscus is a highly effective natural blood pressure modulator. The blood pressure normalizing effect of hibiscus is thought to be mostly attributed to the anthocyanin components of the plant. Its blood pressure modulating properties have been documented in a variety of in vitro, animal and human studies. Hibiscus acts to modulate blood pressure through at least three different mechanisms, including vasodilation (possibly through an NO mediated pathway), a diuretic effect, and through the inhibition of angiotensin converting enzyme (ACE). ACE is an enzyme that produces angiotensin, a molecule that is a potent vasoconstrictor. For this reason, inhibiting ACE is one of the key approaches for modulating blood pressure and is the target of many blood pressure regulating drugs.Hibiscus has also been recently shown to improve cholesterol profiles, triglyceride levels and even blood sugar and insulin resistance.
ResearchGarlicOne 3-month study found that a garlic extract significantly improved cholesterol, triglycerides and fibrinolytic activity. A recent meta-analysis of 26 studies on garlic and cholesterol found that garlic reduces total cholesterol (TC) and triglycerides (TG).L-TheanineL-Theanine is an amino acid found in green tea that is known to reduce stress and promote a relaxed alertness by increasing alpha brainwaves. This kind of state directly precedes stage 1 sleep. Two animal studies have also found blood pressure modulation in rats supplemented with L-Theanine.L-Theanine also indirectly increases the production of GABA, a key inhibitory neurotransmitter in the brain. It is well known for its anti-anxiety effects, but is less often recognized for its effectiveness for promoting normal blood pressure. In one Japanese study, supplementation with 80mg of GABA daily for 8 weeks normalized BP by an average of 10 mmHG and diastolic BP by 5 mmHg in 50 individuals with mildly unhealthy blood pressure levels (systolic BP ranging from 130 to 180 mmHg). Furthermore, certain blood pressure regulating drugs have been shown to increase GABA levels in the hypothalamus, highlighting the importance of this neurotransmitter in the regulation of blood pressure. Studies in rats have shown that GABA is involved in the regulation of nerve cells that control the relaxation and contraction of the muscles in the blood vessel walls. GABA appears to induce blood vessel relaxation, resulting in a more healthy blood pressure level.
Market TrendsOne of the most well-known supplements for heart health is coenzyme Q10 (CoQ10). The most popular blood pressure supplement is Hawthorn. Nitric Oxide is gaining recognition for its important effects on many aspects of health, especially blood pressure and blood vessel health. Green coffee bean extract is currently marketed as a weight loss supplement, although the clinical evidence is of moderate significance.
AOR AdvantageBefore green coffee bean extract was known for weight loss, AOR’s heart and blood pressure health formula contained this now famous extract. Potassium nitrate, mixed vegetable concentrate and Vitamin C work together to yield a high production of nitric oxide in the body, higher than any nitrate or nitric oxide supplement on the market. L-Theanine helps produce GABA in the body, reduces anxiety and may improve sleep, which are important factors in heart health. Ortho•Heart features Hibiscus, whose heart health benefits are not yet well known, as well as the age-old remedy of garlic to maintain good heart health.

AbstractA meta-analysis of randomized, double-blind, placebo-controlled trials for the effects of garlic on serum lipid profiles.J Sci Food Agric. 2012 Jul;92(9):1892-902.Zeng T, Guo FF, Zhang CL, Song FY, Zhao XL, Xie KQ.BACKGROUND: Inconsistent results were obtained for the lipid-regulating effects of garlic in clinical trials. With increasing interest in complementary medicine for hyperlipoidemia, it is important to explore the real effects of garlic. This meta- analysis was performed to investigate the influence of garlic on serum lipid parameters.RESULTS: A total of 26 studies were included into meta-analysis. Overall, garlic was superior to placebo in reducing serum total cholesterol (TC) and triglyceride (TG) levels. Compared with the placebo groups, serum TC and TG levels in the garlic group were reduced by 0.28 (95% CI, – 0.45, – 0.11) mmol L(-1) (P = 0.001) and 0.13 (95% CI, – 0.20, – 0.06) mmol L(-1) (P < 0.001), respectively. The effects of garlic were more striking in subjects with long-term intervention and higher baseline TC levels. Garlic powder and aged garlic extract were more effective in reducing serum TC levels, while garlic oil was more effective in lowering serum TG levels. In contrast, garlic did not influence other lipid parameters, including low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), apolipoprotein B, and TC/HDL-C ratio.CONCLUSION: Garlic could reduce serum TC and TG levels, and garlic therapy should benefit patients with risk of cardiovascular diseases. Acute blood pressure lowering, vasoprotective, and antiplatelet properties of dietary nitrate via bioconversion to nitrite. Hypertension. 2008;51:784-790.Webb, A., et al.Diets rich in fruits and vegetables reduce blood pressure (BP) and the risk of adverse cardiovascular events. However, the mechanisms of this effect have not been elucidated. Certain vegetables possess a high nitrate content, and we hypothesized that this might represent a source of vasoprotective nitric oxide via bioactivation. In healthy volunteers, approximately 3 hours after ingestion of a dietary nitrate load (beetroot juice 500 mL), BP was substantially reduced (Delta(max) -10.4/8 mm Hg); an effect that correlated with peak increases in plasma nitrite concentration. The dietary nitrate load also prevented endothelial dysfunction induced by an acute ischemic insult in the human forearm and significantly attenuated ex vivo platelet aggregation in response to collagen and ADP. Interruption of the enterosalivary conversion of nitrate to nitrite (facilitated by bacterial anaerobes situated on the surface of the tongue) prevented the rise in plasma nitrite, blocked the decrease in BP, and abolished the inhibitory effects on platelet aggregation, confirming that these vasoprotective effects were attributable to the activity of nitrite converted from the ingested nitrate. These findings suggest that dietary nitrate underlies the beneficial effects of a vegetable-rich diet and highlights the potential of a “natural” low cost approach for the treatment of cardiovascular disease. Dietary Supplement with Vitamin C Prevents Nitrate Tolerance.J. Clin. Invest. 102(1): 67-71.Bassenge E, Fink N, Skatchkov M, and Fink BEnhanced formation of superoxide radicals has been proposed to play a major role in the development of nitrate tolerance in humans. We tested the effects of vitamin C (Vit-C) supplementation on glyceroltrinitrate (GTN)-induced hemodynamic effects during 3-d nonintermittent transdermal administration of GTN (0.4 mg/h) in nine healthy subjects. Tolerance development was monitored by changes in arterial pressure, dicrotic digital pulse pressure, and heart rate. Studies with GTN, Vit-C, or GTN/Vit-C were successively carried out at random in three different series in the same subjects. GTN treatment caused an immediate rise in arterial conductivity (a/b ratio of dicrotic pulse), but within 2 d of initiating GTN, the a/b ratio progressively decreased and reached basal levels. In addition, there was a progressive loss of the orthostatic decrease in blood pressure. However, coadministration of Vit-C and GTN fully maintained the GTN-induced changes in the orthostatic blood pressure, and the rise of a/b ratio was augmented by 310% for the duration of the test period. Changes in vascular tolerance in GTN-treated subjects were paralleled by upregulation of the activity of isolated platelets, which was also reversed by Vit-C administration. These findings demonstrate that dietary supplementation with Vit-C eliminates vascular tolerance and concomitant upregulation of ex vivo-washed platelet activity during long-term nonintermittent administration of GTN in humans. Dietary nitrite prevents hypercholesterolemic microvascular inflammation and reverses endothelial dysfunctionAm J Physiol Heart Circ Physiol 296: H1281–H1288, 2009.Stokes KY, Dugas TR, Tang Y, Garg H, Guidry E and Bryan NS.The nitrite anion is an endogenous product of mammalian nitric oxide (NO) metabolism, a key intermediate in the nitrogen cycle in plants, and a constituent of many foods. Research over the past 6 years has revealed surprising biological and cytoprotective activity of this anion. Hypercholesterolemia causes a proinflammatory phenotype in the microcirculation. This phenotype appears to result from a decline in NO bioavailability that results from a reduction in NO biosynthesis, inactivation of NO by superoxide, or both. Since nitrite has been shown to be potently cytoprotective and restore NO biochemical homeostasis, we investigated if supplemental nitrite could attenuate microvascular inflammation caused by a high cholesterol diet. C57Bl/6J mice were fed either a normal diet or a high cholesterol diet for 3 wk to induce microvascular inflammation. Mice on the high cholesterol diet received either nitrite-free drinking water or supplemental nitrite at 33 or 99 mg/l ad libitum in their drinking water. The results from this investigation reveal that mice fed a cholesterol-enriched diet exhibited significantly elevated leukocyte adhesion to and emigration through the venular endothelium as well as impaired endothelium-dependent relaxation in arterioles. Administration of nitrite in the drinking water inhibited the leukocyte adhesion and emigration and prevented the arteriolar dysfunction. This was associated with sparing of reduced tetrahydrobiopterin and decreased levels of C-reactive protein. These data reveal novel anti-inflammatory properties of nitrite and implicate the use of nitrite as a new natural therapy for microvascular inflammation and endothelial dysfunction associated with hypercholesterolemia.
