When does vasodilation happen?
Vasodilation happens when the smooth muscular wall of our blood vessels formed by endothelial cells relax and widen. This occurrence allows for maximum nutrients and oxygen to flow to all areas of the body - and in fact, all organs are affected by vasodilation. It’s a mechanism that we want to nurture for that reason. When vasodilation decreases, this is called vasoconstriction; meaning the flow of oxygen and nutrients carried by our blood vessels is constricted. So improvement of vasodilation can occur by removing stimuli that cause blood vessels to contract or by adding stimuli that supports blood vessel relaxation.
A healthy individual with a plant-based diet full of vasodilator foods and daily exercise can expect to have consistent vasodilation. Certain conditions impact vasodilation, some in our control, such as lifestyle choices and other unavoidable factors, like age.
Why is vasodilation necessary?
Vasodilation is a natural occurrence in our bodies. In response to a need for increased nutrients and oxygen, say during an intense workout, our tissue will release nitric oxide which dilates blood vessels. Or, when we go up high in elevation where there’s less oxygen, we need vasodilation to kick in and compensate for the reduction in oxygen. Our bodies need to have this response so that there’s a healthy, level-appropriate supply of oxygen and nutrients sent to our vital organs and muscles to help us perform at our best. To be vasodilation-vigilant means to remove factors that decrease it and increase factors that improve it.
What are the factors that decrease vasodilation?
Stress - stress contributes to vasoconstriction because it activates the sympathetic nervous system, our flight or fight response.
Age - Aging decreases the functioning of vasodilation; for example, the vasodilating gas nitric oxide is produced 10% less every decade. As we age, we have to work against this natural deterioration.
Weight - Being overweight affects the function of vasodilation and it is thought that the hyperactivity mode of the sympathetic neural system for overweight people is a big part of this reaction.
What are the factors that improve vasodilation?
Exercise - exercise-induced vasodilation happens when a boost in demand for oxygen happens by the exertion of muscles.
Temperature - heat increases vasodilation as blood vessels push heat out through the skin to keep core temperatures cool.
Elevation - The decrease in oxygen that occurs as we go up in elevation causes the body to respond by increasing vasodilation to help maintain oxygen levels throughout the body.
Diet - One of the greatest factors that impact vasodilation is the foods we eat. Higher fat, salt, and sugar content in foods produce vasoconstricting effects, while a plant-based diet high in vasodilator foods help keep arteries and blood vessels relaxed and transport vital nutrients and oxygen.
Top 20 Vasodilator Foods
Considered a major vasodilator food for its intense oxygen delivery, beets increase nitrate intake, which the body converts to nitric oxide. This potent vasodilating gas is a marker of health and vitality. Beets have been a core subject of study and usage in promoting overall health and sports supplementation.
Red spinach is the new beet. The amaranth plant (not technically spinach) has been discordant to have an even higher nitrate concentration per weight than beets. It’s a durable plant that is challenging to find in the market but can be sourced clean from red spinach plant to powder with no additives. Because of its high nitrate content, top athletes leverage red spinach for the ultimate nitric oxide boost.
Ubiquitous in any market, is associated with cardiovascular health because of its powerful vasodilating property, a rise in nitric oxide levels.
According to research, the polyphenols in pomegranates are more powerful in their vasodilating properties than other fruits containing polyphenols.
In clinical studies, many varieties of tart cherry juice have proven time and time again as a powerful weapon for health and reduced cardiovascular events.
A part of the Chenopodiaceae subfamily of the higher Amaranthaceae family of plants is related to beets and spinach. As a chenopodium plant, it induces relaxation of smooth muscle around blood vessel walls.
Hesperidin is a flavinoid in orange juice that has been associated with a remarkable impact on vasodilation, according to research. Citrus fruits contain Vitamin C, a powerful antioxidant; as a group, they are also responsible for protecting and increasing the lifespan of nitric oxide in the body.
The gasses that garlic helps the body produce and regulate are its biggest contributors to vasodilation. The polysulfides in garlic stimulate the production of vascular hydrogen sulfide as well as regulate the production of endothelial nitric oxide, both of which are types of signaling molecules that help the body communicate and transport vital oxygen and nutrients.
Arugula, Kale, and other Leafy Greens
Leafy greens contain high amounts of nitrate, which help facilitate more nitric oxide production via the nitrate‐nitrite‐NO pathway. Leafy green’s potassium contents also help counteract heavy salt intake helping to make leafy greens a vital dietary contributor to vasodilation.
Legumes are recommended to eat for longevity and heart health. Many components contribute to this dietary staple, including a high rate of dietary nitrate. Studies show that intake of legumes four times a week can significantly improve cardiovascular health.
A regarded source of L-arginine, a nitric oxide precursor, walnuts contain some of the highest antioxidants of any nuts, making it a top nut for vasodilation.
one of the greatest known sources of L-citrulline which makes L-arginine bioavailable for nitric oxide synthase and boosts vasodilation.
Including blueberries, strawberries, raspberries, and blackberries, c contain powerful flavonoids which include anthocyanin and proanthocyanidin that substances reduce cell damage and have been shown to increase the production of nitric oxide in blood vessels.
Both green tea and black tea help vasodilation by way of EGCG and theaflavins, respectively. Studies conclude that tea is a powerful contributor to cardiovascular and metabolic health.
Contributing to healthy cholesterol levels, almost produce a boost of L-Arginine to the system that prompts nitric oxide production which improves vasodilation.
containing some of the highest rates of L-arginine, chickpeas not only help vasodilation by direct supply of the important amino acid but also help in weight management.
Studies on the SP6 peptide in spirulina show dramatic support in endothelial vasorelaxation and are an extremely useful food for heart health.
Packs in powerful amounts of nitrate and antioxidants, especially carotenoids that aid in reducing the oxygen necessary for executing exhaustive tasks and also support a healthy heart by way of increasing vasodilation.
Studies show that within 2 hours of consuming mangoes, relaxation of blood vessels occurs. Mangoes contain many antioxidants, especially beta-carotene, such as carotenoids help regulate endothelial function.
a well-known heart-healthy food. Orange flesh sweet potatoes contain higher concentrations of protein, flavonoids, anthocyanins, and carotenoids than white flesh sweet potatoes and promote vasodilation.
How nitric oxide works to increase vasodilation
Nitric oxide is a gaseous molecule that is produced by the body in various ways. It is a signaling molecule produced by almost every cell type in the body. Nitric oxide plays a core role in vasodilation by relaxing the smooth muscle around blood vessels allowing a widening effect to occur. Nitric oxide is a determining health factor according to leading doctors.
The NutriGarden family of products were made to boost nitric oxide levels for everyday health and punctuated athletic performance. Our labels are the cleanest on the market, providing 100% plant-based, vasodilator food ingredients for nitric oxide boosting that are vegan, Non-GMO, preservative-free, gluten-free, with no added sugar or artificial flavor.
