Albaspine, a novel ingredient in cardiovascular health, intricately influences blood pressure regulation through its mastery of vasodilation mechanisms.

Albaspine is a compound found in various species of plants, particularly those belonging to the genus Albizia. It is a white crystalline substance that often forms needle-like crystals. Albaspine can be isolated from the bark or leaves of these plants through extraction techniques.

It goes beyond generic vasodilation; it finely tunes endothelial nitric oxide synthase eNOS activity. By augmenting eNOS function, Albaspine ensures a steady supply of NO, a critical mediator in maintaining vascular tone. Simultaneously, it facilitates beta-adrenergic receptor activity, promoting vasodilation.

Limited stock — order now by clicking here! By suppressing these inflammatory signals, Mallow Flower exerts a profound effect on endothelial function. Scientifically, Mallow Flower engages in modulating nuclear factor-kappa B NF-κB signaling, a central player in the inflammatory cascade.

Through this modulation, it curtails the expression of adhesion molecules and chemokines, mitigating immune cell infiltration and vascular inflammation.

This anti-inflammatory ballet not only preserves endothelial integrity but also contributes significantly to the regulation of blood pressure by maintaining vascular homeostasis. Lasuna bulb, also known as garlic bulb, typically has a whitish papery skin covering multiple cloves. The cloves are usually arranged in a circular shape, forming the bulb.

When peeled, each clove reveals a smooth and firm texture with a distinct pungent aroma and flavor. Allicin, the active compound in garlic, exerts multifaceted actions, primarily through its impact on endothelial function and oxidative stress.

Beyond its role in vasodilation, allicin showcases potent antioxidant properties, combating oxidative stress and preserving NO bioavailability — supporting blood pressure regulation. EGCG in Camellia Sinensis orchestrates a symphony of effects, from modulating autonomic nervous system activity to enhancing endothelial function.

It inhibits angiotensin-converting enzyme ACE , reducing the production of angiotensin II and curtailing vasoconstriction. Simultaneously, EGCG engages in vasodilation by promoting nitric oxide NO synthesis, contributing to optimal blood flow and pressure.

Abstract Background Changes in blood pressure BP may affect pain. Results Pain perception of training groups after the last session was significantly higher than control conditions, and at this time, the magnitude of BP responses was lower in training groups. Conclusion It seems that training-induced hypotension can alter pain perception in hypertensive women through changes in baroreceptor activation.

Implications Training-induced adaptations exhibit an increase in pain perception through reducing systolic blood pressure. There is a trend to go up in pain threshold following resistance exercise.

Blood pressure is associated negatively with pain perception. Background In recent years, the number of studies investigating the health-related properties of green tea GT , including neuroprotective effects [ 1 ] have risen dramatically.

No supplement is intended to treat, cure, or prevent disease. The potential health benefits of EGCG are numerous and extend to brain and heart health, cancer prevention, and multiple sclerosis. Here's the scoop on the research. A systematic review suggested drinking at least milliliters mL about 3 ounces of green tea daily boosted cognition and brain function and may reduce the risk of dementia.

Green tea also enhanced memory and attention span. The cognitive benefits of green tea are well established. However, it is unclear whether EGCG or other compounds found in green tea are responsible for these positive health effects.

Some studies of human brain cells in vitro research, performed in a lab suggested EGCG crossed the blood-brain barrier , a layer of cells that protects the brain from harmful substances. Regularly consuming green tea improves memory and mood and protects against depressive symptoms. Research suggests that milligrams mg of EGCG may increase calmness and reduce stress.

However, other research notes improved overall mood only with higher dosages mg of EGCG, and achieving mg EGCG through green tea alone is difficult. One cup 8 ounces of brewed green tea has mg of EGCG. Reaching mg of EGCG would require drinking an amount of green tea that would exceed caffeine recommendations of mg daily.

This is not recommended. Adding green tea to your routine may keep your blood pressure in a healthy range. Research shows that consuming any amount of green tea daily lowers blood pressure compared to not drinking green tea.

Catechins in green tea, like EGCG, improve blood pressure by increasing nitric oxide production. Nitric oxide is a chemical that enlarges blood vessels, causing blood pressure to decrease. One randomized controlled trial observed a decrease in blood pressure after eight weeks with mg EGCG taken twice daily.

Despite the beneficial effects of green tea on blood pressure, limited research exists on the specific influence of EGCG. Catechins in green tea, such as EGCG, may prevent cells from dividing and spreading. Among randomized controlled trials, dosages of EGCG vary and are often higher than typically found in green tea.

You would need to drink eight glasses of green tea to achieve the same amount of EGCG found in a supplement. Some research suggests a link between drinking green tea and a reduced risk of cancer.

However, much of the evidence is inconsistent. Again, it is unclear if EGCG supplements will yield the same benefits as green tea. The National Cancer Institute believes insufficient evidence exists to support or reject EGCG for cancer prevention decisively. Multiple sclerosis MS is a chronic condition in which the body attacks the central nervous system , impacting communication between neurons and the brain.

Some people with MS may experience the following symptoms:. Animal research found a neuroprotective brain protecting and anti-inflammatory effect of EGCG. However, human studies have not observed similar results.

One small study of people with progressive MS observed no difference in the loss of brain cells brain atrophy between participants taking up to 1, mg EGCG daily and those given a placebo. Research suggests EGCG may reduce low-density lipoprotein LDL cholesterol.

Elevated cholesterol, particularly LDL, is a significant risk factor for cardiovascular disease CVD. Consuming 2 to 8 cups of green tea daily lowers LDL and total cholesterol levels. Evidence conflicts on the benefits of EGCG supplements for triglyceride levels.

But other research shows increased triglyceride levels with green tea catechin or EGCG supplements. While some research demonstrates the cholesterol-lowering ability of EGCG supplements, no conclusive evidence exists to support a specific dosage.

EGCG may increase the amount of energy your body uses for normal functioning energy expenditure. One meta-analysis found that mg EGCG daily could promote greater energy metabolism. Another study found that consuming to mg of EGCG with 80 to mg of caffeine daily for at least 12 weeks supported weight loss and encouraged greater changes to body composition.

However, whether the same effects can be achieved with EGCG supplementation alone is unknown. There is no specific dose recommendation to reap the benefits of EGCG.

The FDA classifies EGCG and green tea catechins as generally recognized as safe GRAS but does not provide specific dosage recommendations. Moreover, dosages and supplement forms used in studies vary.

A 1-cup 8 ounces or mL serving of green tea provides roughly mg of EGCG. However, this amount can vary, depending on the type of tea leaf and processing and storing methods.

Matcha tea is more concentrated than green tea. Some research indicates matcha may contain times the amount of EGCG as green tea. Concentrated capsules or tablets of green tea extract or catechins contain higher amounts of EGCG. Depending on the supplement, dosages can range from 25 to mg of EGCG.

Green tea extract added to drink products provides an average of mg EGCG per serving. Still, some research suggests that 1, to 1, mg daily for three months can be safe. The National Center for Complementary and Integrative Health NCCIH at the National Institute of Health NIH notes that it is safe to consume up to 8 cups of green tea daily providing nearly 1, mg EGCG.

It is not recommended to ingest more than mg of concentrated EGCG daily in solid supplement form. However, it can be easy to exceed this amount with capsule or tablet supplements. Potential side effects of green tea extract pills include the following:. Liver problems may occur with green tea extracts in pill form.

People with liver disease should be more cautious, as higher doses of concentrated EGCG can contribute to liver problems.

Consult with a healthcare provider immediately if you are taking a green tea extract pill and experience these symptoms, as it may be a sign of liver trouble. EGCG may interact with certain medications. These medications include the following:. Consult your healthcare provider before starting a supplement, as other interactions are possible.

The following precautions should be noted for use of EGCG and products containing green tea and thus caffeine :. In the United States, the Food and Drug Administration FDA does not regulate supplements the way it regulates prescription drugs.

That means some supplement products may not contain what the label says. When choosing a supplement , look for products tested by third parties, such as U. Pharmacopeia USP or ConsumerLab. com, and consult a healthcare provider, an RD or RDN, or a pharmacist.

EGCG may improve mood, cognition, cholesterol, and blood pressure. Although the potential benefits of EGCG are plentiful, questions remain about the effectiveness of EGCG-specific supplements.

Regularly drinking green tea provides EGCG and other nutrients beneficial to health without exceeding recommended EGCG dosages. Despite the advantages of green tea, it is still important to be mindful of the caffeine content. EGCG is a plant compound polyphenol found in green tea leaves.

EGCG is associated with numerous health benefits. Capsule or tablet supplements of EGCG up to doses of mg daily appear safe for most individuals. People with liver disease or a history of liver issues should consult their healthcare provider before taking EGCG supplements.

Some EGCG supplements contain caffeine, while others do not. Read the supplement label carefully. Onakpoya I, Spencer E, Heneghan C, et al. The effect of green tea on blood pressure and lipid profile: a systematic review and meta-analysis of randomized clinical trials.
