Alpha-lipoic acid, alternatively referred to as thioctic acid, serves a pivotal function in adjunctive therapy for a spectrum of metabolic disorders, including type 2 diabetes mellitus, insulin resistance, and elevated blood pressure. What risks are associated with its supplementation, including potential adverse effects and circumstances where its use is contraindicated? Furthermore, how does the product landscape appear within the United Kingdom—what formulations are currently accessible, and within what price range can they be procured?

Kwas alfa-liponowy – właściwości

Kwas alfa-liponowy (w skrócie: R-ALA) jest związkiem organicznym z grupy kwasów karboksylowych.. Niegdyś uważano go za witaminę, jednak fakt, iż organizm (zarówno roślinny, jak i zwierzęcy) zdolny jest do jego endogennej syntezy sprawił, że został on wykluczony z tej grupy.. Wnioski licznych badań przeprowadzonych z wykorzystaniem R-ALA dostarczyły istotnych informacji o jego właściwościach.. Okazuje się, iż kwas alfa-liponowy wykazuje istotne działanie przeciwutleniające (neutralizuje wolne rodniki i wspiera endogenny system antyoksydacyjny organizmu), przeciwzapalne i przeciwstarzeniowe.. Ma zdolność do poprawy wrażliwości insulinowej i tolerancji glukozy przez organizm.. Jego rola w przywróceniu elastyczności ścian naczyń krwionośnych oraz rozszerzeniu ich światła jest z kolei pomocna w przypadku choroby niedokrwiennej serca i nadciśnienia.. Wnioski niektórych badań naukowych sugerują, iż R-ALA może być suplementem wspierającym proces utraty masy ciała, jednak w tym aspekcie jego działanie nie jest silne.. Konieczność dalszych badań nad tym kwasem pomoże stwierdzić, czy poza – już odkrytymi właściwościami – wykazuje on inne, dotąd nieznane działanie na organizm ludzki.

Kwas alfa-liponowy – skutki uboczne

Mimo iż kwas alfa-liponowy jest związkiem syntezowanym w organizmie oraz w niewielkich ilościach występującym naturalnie w pewnych produktach spożywczych (głównie w brokułach, szpinaku, podrobach, wołowinie), jak każdy związek przyjmowany w postaci suplementu, może wykazywać pewne skutki uboczne.. Choć z reguły są one niegroźne i występują głównie w przypadku przedawkowania, należy pamiętać o możliwych objawach niepożądanych – najczęściej ze strony przewodu pokarmowego (biegunkę, bóle brzucha).. Podobnie jak w przypadku wielu innych suplementów, ostrożność powinny zachować kobiety w ciąży i okresie karmienia, dzieci i osoby starsze.. Diabetycy powinni uzgodnić ewentualną suplementację z lekarzem tak, aby nie doprowadzić do zbyt gwałtownych wahań poziomu cukru we krwi i hipoglikemii spowodowanych uwrażliwieniem komórek na insulinę wywołanym przez R-ALA.. Podobną ostrożność powinny zachować osoby przyjmujące leki na nadciśnienie, gdyż kwas alfa-liponowy – poprzez rozszerzenie światła naczyń krwionośnych – może prowadzić do obniżenia ciśnienia poniżej wartości prawidłowych.. W przypadku przyjmowania dużej ilości suplementów o działaniu przeciwutleniającym należy pamiętać, iż w organizmie musi być utrzymana równowaga prooksydacyjno-antyoksydacyjna, co – mówiąc w uproszczeniu – oznacza balans pomiędzy ilością wolnych rodników a przeciwutleniaczy.. Przewaga zarówno w jedną, jak i drugą stronę jest dla organizmu zjawiskiem niekorzystnym, a przyjmowanie zbyt dużej ilości suplementów o działaniu antyoksydacyjnym taką równowagę może zaburzać.. R-ALA nie zaleca się przyjmować bezpośrednio po treningu siłowym, gdyż jego działalność przeciwutleniająca nie jest w tym momencie pożądana – najlepiej zachować odstęp między przyjmowanymi przeciwutleniaczami a treningiem, szczególnie siłowym.

Kwas alfa-liponowy – preparaty

Kwas alfa-liponowy dostępny jest na polskim rynku w sklepach z suplementami diety, najczęściej tymi internetowymi.. Najpopularniejszą formą R-ALA są kapsułki, różniące się w zależności od producenta zawartością kwasu liponowego.. Najpopularniejsze firmy posiadają w ofercie R-ALA w ilości 600 mg w 1 kapsułce, jednak można spotkać również takie o mniejszej zawartości substancji czynnej (100 mg, 300 mg, 500 mg).. Dawka suplementu zależy od celu, jaki chcemy osiągnąć – działanie przeciwutleniające może wykazywać już dawka 100 mg, podczas gdy w cukrzycy zaleca się dawki 300 – 600 mg/dobę (po konsultacji z lekarzem).. Dawki używane w badaniach naukowych z udziałem ochotników bywają jeszcze wyższe, sięgając 1800 mg/ dobę [1].

Kwas alfa-liponowy – cena

Cena suplementu zależy od zawartości R-ALA i ilości sztuk w opakowaniu.. Przeciętna cena 60 kapsułek zawierających 600 mg kwasu alfa-liponowego to koszt około 50 zł.. Cena waha się również w zależności od producenta.. Kwas alfa-liponowy to stosunkowo bezpieczny suplement, rzadko powodujący skutki uboczne.. Podobnie jak w przypadku innych środków, należy zachować ostrożność i rozważyć celowość jego przyjmowania.. Kwas R-ALA można nabyć najczęściej w postaci kapsułek (60 sztuk o zawartości 600 mg), za które zapłacimy średnio 50 zł.
