Olive Leaf Extract Tea

Ciyuan®- Your Trusted Supplier of Olive Leaf Extract Tea

The main source of the potential benefits of Olive Leaf Extract Tea is the presence of a sui generis combination of bioactive compounds, the best studied of which, is oleuropein. Oleuropein is one of the phenolic glycoside which occurs plentifully in the olive leaf up to 6-9 percent of the dry weight. After being ingested oleuropein is broken down to new hydroxytyrosol, a strong antioxidant that also has its own health benefits.​

It also has other important constituents like tyrosol (phenylethanoid alcohol), luteolin, apigenin and rutin (all flavonoids). Combined, these compounds increase the antioxidant, anti-inflammatory and vasodilatory properties of the extract and all qualities are as pertinent to cardiac health.​

The concentration of these compounds in olive leaf extract varies by product, with many manufacturers standardizing oleuropein content (often between 10-40%) to ensure consistency and potency.​

The role Olive Leaf Extract Tea can play in keeping the Heart Healthy​

1. Mrentenance of health blood pressure levels​

Among the well-known potential benefits of taking olive leaf  capsules, there is the promotion of maintaining healthy blood pressure levels in a normal range. This effect has been examined in a couple of studies, successfully.​

It is thought that Oleuropein has a naturally wound relaxing effect on the blood vessels, i.e. is a vasodilator. This dilacement softens the blood flow so that healthy blood pressure can be maintained. In one study investigated in 2017 and published in the Journal of Medicinal Food, participants showed modest decreases in systolic blood pressure after taking olive leaf extract for eight weeks relative to a group taking placebo. The researchers explained this effect by the capability of oleuropein to increase the nitric oxide production which informs blood vessels to relax.​

Additionally, olive leaf extract may inhibit the activity of angiotensin-converting enzyme (ACE), an enzyme that constricts blood vessels and raises blood pressure. Inhibition of ACE by the extract assists in preserving arterial elasticity and hence a constant flow of blood.​

2. Supporting Healthy Cholesterol Profiles​

A key element of cardiovascular health is management of cholesterol and olive leaf extract tablets can help support already healthy cholesterol levels.​

LDL cholesterol is harmful when oxidized since it can result in the development of plaque at the innermost walls of the circulatory system. The olive leaf extract has been found useful in the inhibition of LDL oxidation by the presence of the antioxidants and the hydroxytyrosol. A more recent study published in Phytomedicine in 2011 showed that supplementing with olive leaf extract lowered markers of oxidative stress in healthy patients with mild hypercholesterolemia indicating a potential protective effect against oxidation of LDL.​

Moreover, In some studies the olive leaf extract is been shown to have a possible moderate increase in HDL cholesterol level. HDL plays a central role in sustaining good cholesterol levels by aiding in the elimination of surplus cholesterol by taking this compound to the liver where it can be rid of. One 2020 review published in Nutrients stated that several studies have witnessed this trend but the mechanism by which it occurs has not been fully determined.​

3. Promoting the work of Endothelium​

A thin layer of cells that lines the inside of the blood vessels is called the endothelium and its effective functioning is an essential part in cardiovascular health. A intact endothelium controls blood circulation, blood stasis and inflammation.​

As described above, olive leaf extract has been indicated to assist in the diversion of endothelial function to release nitric oxide. Nitric oxide also dilates the walls of blood vessels it enhances blood flow and lightens the work on the heart. A research study published in The Journal of Cardiovascular Pharmacology in 2019 discovered that the supplementation of olive leaf extract improved endothelial function of healthy adults where researchers attribute this action towards antioxidant end-points of the extract.​

Promoting endothelial health, olive leaf extract can contribute to eliminating the chances of blood vessels damage and keeping the blood circulation in the body optimized.​

4. Reducing Oxidative Stress and Inflammation​

Chronic inflammation and oxidative stress are two inter-related factors that cause strain on the heart. Oxidative stress is a result of free radicals swamping the body antioxidant defense system and destroying cells and tissues. Although inflammation is a natural part of the immune system, it may be chronic and damage the walls of the blood vessels.​

Olive leaf extract is packed with antioxidants that offset free radicals, which lessen oxidative stress. Especially hydroxytyrosol, which is considered as highly efficient antioxidant and was even ranked as one of the strongest natural antioxidants in a 2018 article on Food Chemistry.​

Additionally, the phenolic compounds in olive leaf extract inhibit pro-inflammatory enzymes and cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). Reduction in inflammation assists the extract in the preservation of blood vessels and the wellbeing of the whole cardiovascular system. A 2016 article published in Phytotherapy Research concluded that the supplementation of olive leaf extracts with olive leaf extracts lowers inflammation markers in subjects with metabolic syndrome, which is a disease related to cardiovascular risk.​

5. Tending to Good Blood Sugar and Insulin Sensitivity ​

Although it is not a cardiovascular marker, insulin and control of blood sugar are directly related to cardiovascular health. The elevated levels of sugar in the blood may ruin blood vasculature in the long run and insulin resistance is a predisposing factor to cardiovascular concerns.​

Olive leaf extract can assist in bringing down and maintaining healthy blood sugar levels by enhancing insulin sensitivity. One study, conducted in Diabetes Research and Clinical Practice in 2015, showed that type 2 diabetes patients who used olive leaf extract resulted in a significant improvement in their insulin sensitivity and fasting blood glucose levels relative to a control group. The researchers proposed that oleuropein can increase the intake of glucose in the cells, meaning there would be less need to produce insulin a lot.​

Olive Leaf Extract Tea also help promote heart health by maintaining healthy blood sugar and insulin levels, since consistent glucose levels minimize the chances of damage to blood vessels.​

Clinical Evidence and Research Limitations​

The capacity of the olive leaf extract to achieve an improvement in cardiovascular terms is justified by the increasing number of studies, nevertheless, the limitations should be mentioned. Furthermore, results have been reported in most studies carried out so far that are either small scale or on animals and therefore need a large, long-term clinical trial involving human beings to be sure of such effects.​

As an illustrative example, a meta-analysis (see) in Complementary Therapies in Medicine publication in 2021 of 17 randomized controlled trials showed that olive leaf extract supplementation may decrease SBP modestly and reduce total cholesterol levels. It was also observed, however, that there is much variability in study designs and dosing, which contributes to the case that more standardized studies must be implemented.​

It is also fair enough to mention that olive leaf extract is usually researched in a combination with a right diet and physical exercising being considered a wholesome lifestyle. Its effects are not an alternative to medical treatment of already-existing cardiovascular conditions but serve to augment an integrative perspective of heart health.
