Definition"},"content":{"rendered":"<h1>Epigallocatechin gallate \u2013 the most valuable polyphenol of green tea, with broad biological potential<\/h1>\n<h2>What epigallocatechin gallate is<\/h2>\n<p>Epigallocatechin gallate, more often referred to by the abbreviation EGCG, is one of the most powerfully acting natural polyphenols found in the leaves of green tea. It is the main catechin responsible for the health-promoting properties of this drink, and its activity covers cellular protection, support for metabolism, an anti-inflammatory action and the regulation of many physiological processes. Contemporary science devotes an enormous number of studies to EGCG, because this compound shows the ability to modulate cellular pathways connected with regeneration, immunity and ageing.<\/p>\n<h2>How EGCG works at the cellular level<\/h2>\n<p>EGCG is a strong antioxidant that neutralises free radicals before they lead to damage to proteins, lipids or DNA. Its action is not limited, however, to the stabilisation of reactive oxygen species \u2013 epigallocatechin gallate also influences the signalling pathways responsible for cell proliferation, their regeneration and the immune response. This compound activates detoxifying enzymes, supports the repair of cellular structures and regulates the expression of genes responsible for the homeostasis of the body. EGCG also acts on the mitochondria, strengthening their energy capacity, which has a direct influence on the level of vital strength.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro-1024x683.webp\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" srcset=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro-1024x683.webp 1024w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro-300x200.webp 300w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro-768x512.webp 768w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro-260x173.webp 260w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro-600x400.webp 600w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-epigalusan-gallokatechiny-slownik-liposom-dwatro.webp 1181w\" alt=\"what is epigallocatechin gallate\" width=\"1024\" height=\"683\" \/><\/p>\n<h2>Anti-inflammatory and antioxidant action<\/h2>\n<p>Chronic inflammation is one of the main factors accelerating ageing and the development of lifestyle diseases. Epigallocatechin gallate inhibits the activity of pro-inflammatory mediators and reduces the production of inflammatory cytokines. At the same time it strengthens the antioxidant defence of the cells, thanks to which the body becomes more resistant to oxidative stress. EGCG also has a protective effect on the lipids of the cell membranes and stabilises their structure, which additionally strengthens the integrity of the tissues.<\/p>\n<h2>The influence of epigallocatechin gallate on metabolism<\/h2>\n<p>EGCG influences the regulation of glucose and fat metabolism. It increases thermogenesis, that is, the process of burning energy, and improves insulin sensitivity. This compound supports the control of body weight, reduces the absorption of lipids in the digestive tract and regulates the work of metabolic enzymes. Thanks to this, its action is important both in the prevention of obesity and in the regulation of the energy balance. These effects are particularly clearly visible when EGCG is used in a highly absorbable form.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro-1024x680.webp\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" srcset=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro-1024x680.webp 1024w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro-300x199.webp 300w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro-768x510.webp 768w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro-260x173.webp 260w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro-600x398.webp 600w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-liposom-dwatro.webp 1181w\" alt=\"what is epigallocatechin gallate\" width=\"1024\" height=\"680\" \/><\/p>\n<h2>Protection of the cardiovascular system<\/h2>\n<p>Epigallocatechin gallate supports the elasticity of the blood vessels and protects LDL lipoproteins against oxidation, which is one of the most important stages in the formation of atherosclerotic changes. EGCG supports normal blood pressure, reduces the level of oxidative stress in the vascular endothelium and improves the function of the cells responsible for proper blood flow. Regular supplementation with EGCG supports the health of the circulatory system on many levels.<\/p>\n<h2>Epigallocatechin gallate and skin health<\/h2>\n<p>The skin is particularly exposed to oxidative stress and UV radiation. EGCG supports the protection of skin cells against photochemical damage, increases repair processes and reduces inflammation. It also supports the production of collagen and stabilises the elastic fibres, which counteracts sagging and the ageing of the skin. EGCG is increasingly also being introduced into dermo-supplement formulas, where its action is more systemic.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1-1024x574.webp\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" srcset=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1-1024x574.webp 1024w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1-300x168.webp 300w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1-768x430.webp 768w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1-260x146.webp 260w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1-600x336.webp 600w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/dwatro-pigalusan-gallokatechiny-slownik-pojec-1.webp 1181w\" alt=\"what is epigallocatechin gallate\" width=\"1024\" height=\"574\" \/><\/p>\n<h2>The synergy of EGCG with other ingredients<\/h2>\n<p>Epigallocatechin gallate intensifies the action of many active substances. In combination with vitamin C it increases antioxidant protection, and with coenzyme Q10 and resveratrol it supports the mitochondria and slows down ageing processes. Combined with zinc or collagen, in turn, it improves the condition of the skin and supports regeneration processes. Synergy is one of the key elements thanks to which EGCG finds application in modern supplements.<\/p>\n<h2>The bioavailability of EGCG \u2013 why the form matters<\/h2>\n<p>A natural difficulty associated with EGCG is its low stability in the digestive tract. In contact with stomach acid and enzymes it breaks down quickly, which is why classic forms of supplements can be limited in terms of effectiveness. The solution lies in technologies that increase bioavailability \u2013 liposomal transport systems, nanoemulsions and encapsulation. Thanks to them EGCG is protected and its absorption increases many times over.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro-1024x682.webp\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" srcset=\"https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro-1024x682.webp 1024w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro-300x200.webp 300w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro-768x512.webp 768w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro-260x173.webp 260w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro-600x400.webp 600w, https:\/\/dwatrolaboratories.com\/wp-content\/uploads\/2025\/12\/szklanke-herbaty-z-zoltym-plynem-pigalusan-gallokatechiny-dwatro.webp 1181w\" alt=\"what is epigallocatechin gallate\" width=\"1024\" height=\"682\" \/><\/p>\n<h2>Epigallocatechin gallate in DWATRO Laboratories supplements<\/h2>\n<p>The DWATRO Laboratories brand uses EGCG in a form stabilised with the\u00a0<a href=\"https:\/\/dwatrolaboratories.com\/en\/shop\/\" target=\"_blank\" rel=\"noopener\">DWATRO\u00aeLIP<\/a>technology, which considerably increases the bioavailability of epigallocatechin gallate.
