Witamina C – skuteczny antyoksydant

Ludzki organizm nie jest w stanie samodzielnie wytworzyć witaminy C, dlatego monitorowanie jej spożycia jest niezwykle ważne. Dodatkowo medycyna naturalna poleca wykorzystanie tej substancji niemal w każdej jednostce chorobowej, ze względu na fakt, że jest ona jednym z najsilniejszych antyoksydantów w ciele człowieka. Witamina C wpływa na pracę mózgu, serca oraz układu odpornościowego. Ma też znaczenie dla naszego nastroju oraz wykazuje działanie przeciwstarzeniowe i wspiera leczenie nowotworów.

Działanie mózgu i nastrój

Witamina C, zwana również kwasem askorbinowym jest niezbędna dla prawidłowego działania mózgu. Jest tak, ponieważ obniża ona poziom stresu oksydacyjnego oraz nasila procesy neuromodulacyjne, czyli formowanie się nowych naczyń nerwowych w mózgu. Wspiera również formowanie się nowych naczyń krwionośnych. Dodatkowo kwas askorbinowy wpływa na formowanie otoczek mielinowych i przesyłanie informacji przez neuroprzekaźników. Witamina C poprawia też procesy uczenia się czy zapamiętywania. Niewielka ilość warzyw i owoców w diecie może być przyczyną niedoborów witaminy C. Ten z kolei może przyczynić się do obniżenia nastroju, dlatego warto zadbać o odpowiedni poziom tego składnika w przyjmowanych pokarmach. Otóż witamina C zmniejsza uczucie niepokoju, wspiera również leczenie symptomów depresyjnych u dzieci i dorosłych, u których stwierdzono jej niedobory. Nie oznacza to oczywiście, że może ona całkowicie zastąpić farmakoterapię czy psychoterapię. Może być za to skutecznie uzupełniającym je elementem.

Działanie antystarzeniowe

Kwas askorbinowy wspiera zachowanie dobrej formy nie tylko naszego umysłu, ale i ciała. Dzięki utrzymaniu właściwego poziomu witaminy C w organizmie, zmniejszamy ryzyko rozwoju choroby Alzheimera. Co więcej, niedobory tej substancji w okresie starości powodują wzrost stężenia beta amyloidu, który w dużej mierze odpowiedzialny za rozwój chorób neurodegeneracyjnych. Witamina C silnie wpływa też na regenerację i proces odmładzania skóry, dzięki intensywnej syntezie kolagenu. Ponadto jej przyjmowanie i stosowanie może skorygować zmiany strukturalne skóry i naskórka wywołane przez procesy starzenia. Jest tak, ponieważ kwas askorbinowy uczestniczy w tworzeniu bariery skórnej z udziałem kolagenu. Z tego względu wykazuje on działanie przeciwzmarszkowe, czyni skórę bardziej elastyczną oraz przyspiesza gojenie ran oraz regenerację naskórka. Witamina C jest skutecznym wsparciem również w leczeniu trądziku, atopowego zapalenia skóry oraz łuszczycy. Podawanie witaminy C w przypadku tych chorób w widoczny i odczuwalny sposób zmniejszyło ich objawy.

Witamina C a praca serca i układu odpornościowego

Działanie oksydacyjne witaminy C ma również znaczenie dla ludzkiego serca. Obniża przez to ryzyko chorób kardiologicznych i poprawia stan naczyń krwionośnych, ponieważ chroni je przed nadmiarem wolnych rodników. Przyczynia się też do powstawania kolagenu, dzięki czemu wpływa na regenerację uszkodzonych tkanek. Wpływa ona również na funkcjonowanie układu odpornościowego, szczególnie w przypadku stanów zapalnych, które reguluje.
