The Aronvit-branded aronia extract is sourced from the Nero-Eggert variety of aronia berries, developed by aronia cultivation expert Piotr Eggert. It is produced using Greenvit’s PureGreenLine process that combines cold water extraction method and multi-steps membrane filtration. The remaining pulp is also upcycled operating on a zero-waste basis, according to the company.
“Our long-standing dedication to the cultivation, analysis and scientific research of Aronvit and its wellness benefits has earned it a reference position in the United States Pharmacopeia (USP) as a U.S. monograph for aronia extract,” said Rafal Pietruszynski, CEO of Greenvit, in a press release. “We are an official partner of the USP Donor Recognition Program.”
The Piotr Eggert variety reportedly boasts high levels of flavonoids and other polyphenols (at 25%), including anthocyanins (15%) and proanthocyanidins (10%). Moreover, it is rich in vitamins C, E and K, as well as minerals like iron and calcium, the company said.
“Aronia berry is recognized for its high ORAC score as an antioxidant. In fact, it has one of the highest capacities of any berry for absorbing reactive oxygen species (ROS). Over time, ROS have been shown to damage DNA and disrupt cell structure and function, causing inflammation, which, as scientific research indicates, is inherent in metabolic diseases,” Pietruszynski said. “Studies of Aronvit have also demonstrated its positive impact on metabolic health and support of heart health.”
Founded in 2010 and based in Zambrów, Poland, Greenvit produces plant extracts sourced from premium European-origin raw materials. In addition to aronia, the company also offers bilberry, elderberry, lemon balm, nettle, hops, sage, horsetail, thyme and white mulberry, among others.
To serve the U.S. market, Greenvit confirmed it has opened a new headquarters and warehouse in Voorhees, NJ.
Aronia
Aronia is a member of the Rosaceae family native to eastern North America. It has also been naturalized in Europe. Over 80% of the global production of aronia berries comes from Poland, with Greenvit noting that it is often called “Polish black gold”.
The most studied form of chokeberry is Aronia melanocarpa (black chokeberries), but other forms of the berry exist, including Aronia arbutifolia (red chokeberries) and Aronia prunifolia (purple chokeberries).
Although native to North America, commercial cultivation of aronia berries started in the Soviet Union and Eastern Europe. The berry was reportedly used for enhancing the diets of Russian cosmonauts.
The majority of the science supporting the potential health benefits of chokeberry relate to heart health (enhancing blood flow, normalizing blood clots, benefiting blood pressure), but other reported benefits include anti-inflammatory, antioxidant and immunomodulatory effects. A study from the International Journal of Sport Nutrition and Exercise Metabolism also indicated potential for sports nutrition (2005, Vol. 15, pp. 48-58).
Science
A new study using Aronvit supported the aronia extract’s antioxidant potential and positive impact on metabolic and cardiovascular health after six weeks of supplementation at 200 mg per day.
The randomized, double-blind, placebo-controlled pilot trial included 17 men and women between the ages of 26 and 55 with diagnosed hypertension or hypercholesterolemia. The results indicated that the aronia extract was associated with significant reductions in total cholesterol, LDL cholesterol and homocysteine.
In addition, levels of the liver enzyme alanine aminotransferase (ALAT) also decreased significantly, suggesting a positive impact on liver function.
Further analysis indicated that the aronia extract may exert anti-inflammatory benefits, with reductions in a range of pro-inflammatory cytokines and adhesion molecules observed.
Aronvit also increased production of the potent vasodilator nitric oxide (NO), the researchers reported.
“It is crucial to consider standardized aronia extract for cardiovascular health due to its concentrated and consistent composition of bioactive compounds, which may not be present in sufficient quantities in aronia juice and other preserves,” they wrote in the Journal of Functional Foods.
“While aronia juice and products offer some health benefits, standardized extracts provide a more potent and reliable source of bioactive compounds, such as polyphenols, anthocyanins and antioxidants, known for their cardiovascular protective properties. In light of this, further exploration of standardized aronia extract is warranted, offering a potent and reliable source of bioactive compounds crucial for promoting cardiovascular health and warranting continued investigation to optimize metabolic and cardiovascular well-being.”
“The full wellness potential of the aronia berry is still being discovered in the US and around the world,” Pietruszynski stated. “Modern science confirms what people intuitively knew for generations, that aronia is one of the richest sources of natural polyphenols and antioxidants.”
