Koks tas paparastas? Ir jei yra paprastas, tai kokiu dar yra? (mineralinius visi zinom). O is esmes tai cia nesamone suskelei, pirmas dalykas, kuri paauglysteje suzinojau apie maisto papildus, tai kreatino nestabilumas. Pirmas asmuo, kuris teigia priesingai.

Gali skirtis vandens pH. Tai yra  rūgštingumas arba šarmingumas. Normalaus geriamo vandens pH yra neutralus (pH=7). Labiau rūgščiame vandenyje kreatinas greičiau virsta kreatininu. O kad kreatinas yra stabilus vandenyje vieną dieną - MOKSLU PAGRĮSTAS FAKTAS. Man pačiam buvo įdomu ir radau atitinkamus mokslinius tyrimus per google. Antrą dieną jis praranda apie 2% savo stabilios formos, o toliau jau vyksta gana progresiniai pokyčiai. Kartais geriau pačiam pasidomėti, nei aklai tikėti kas ką pasakė.

Sutinku, as irgi esu skaites neviena straipsni kuris teigia jog kreatinas i kreatinina virsta kur kas leciau, nei daugelis yra linke manyti.
Jei neklystu skaiciai kiek kiti buvo nurodyti, taciau nuorodos dabar nerasiu taip greitai, tad nesigincysiu.
Verdiktas - kreatina laikyti vandenyje kelias valandas nera pavojaus pakenkiant jo veiksmingumui, na o kas del laikymo per nakti kogero butu verta dar karta pasitikslinti, nors kogero buciau linkes sutikti su Proto skaiciais.
mazha pastaba - jei kreatina maishote su kitais preworkoutais, ar aakg, ar cm, tada vandens rusghtingumas bus gerokai aukstesni ir kreatino virtimas i kreatinina bus spartesnis.

Db tik siek tiek paskaiciau pirmaji straipsni kur per google ismete ir ten raso pan ka Protas sake. Jei tai tiesa, tada tikrai sorry, mano kalte. Bet tokiu dalyku nebuvo net i galva ateja dometis, nes negalvojau, kad yra naudos kazkam skleisti, jog nestabilus jau po keliu minuciu ar net sekundziu (aisku gamintojams del kitu formos "geresnio" stabilumo, bet, kad vietoj menesiu minutes sugalvotu, tai cia jau ziauriai). Ten kur skaiciau net apie menesius raso. Beje tam mitui tikrai minimum keliolika metu ir galvojau cia jau vos ne kaip aksioma. Cia is to str: Best-case scenario at a pH 7.0 solution (such as tap water) you will have 85% of the original creatine dose you placed in your drink at day 120. So anyone claiming a 100% breakdown of creatine in fluids, juices or similar liquids in minutes or seconds are pulling your chain, or more importantly your purse strings…don’t be fooled!

taigi, ieskojau informacijos apie ivairias kreatino formas ir radau priestaringos informacijos.

ethyl esteris turetu buti stabilesnis nei monohidratas ir be salutiniu poveikiu

kre-alkalyn dar geriau pasisavinamas, taciau radau ir neprklausomu studiju rezultatus, kurie viska sumaiso su zememis.

Creatine ethyl ester rapidly degrades to creatinine in stomach acid

Creatine ethyl ester (CEE) is a commercially available synthetic creatine that is now widely used in dietary supplements. It comprises of creatine with an ethyl group attached and this molecular configuration is reported to provide several advantages over creatine monohydrate (CM). The Medical Research Institute (CA, USA) claim that the CEE in their product (CE2) provides greater solubility in lipids, leading to improved absorption. Similarly San (San Corporation, CA, USA) claim that the CEE in their product (San CM2 Alpha) avoids the breakdown of creatine to creatinine in stomach acids. Ultimately it is claimed that CEE products provide greater absorption and efficacy than CM. To date, none of these claims have been evaluated by an independent, or university laboratory and no comparative data are available on CEE and CM.

This study assessed the availability of creatine from three commercial creatine products during degradation in acidic conditions similar to those that occur in the stomach. They comprised of two products containing CEE (San CM2 Alpha and CE2) and commercially available CM (Creapure?). An independent laboratory, using testing guidelines recommended by the United States Pharmacopeia (USP), performed the analysis. Each product was incubated in 900ml of pH 1 HCL at 37? 1oC and samples where drawn at 5, 30 and 120 minutes. Creatine availability was assessed by immediately assaying for free creatine, CEE and the creatine breakdown product creatinine, using HPLC (UV)

After 30 minutes incubation only 73% of the initial CEE present was available from CE2, while the amount of CEE available from San CM2 Alpha was even lower at only 62%. In contrast, more than 99% of the creatine remained available from the CM product. These reductions in CEE availability were accompanied by substantial creatinine formation, without the appearance of free creatine. After 120minutes incubation 72% of the CEE was available from CE2 with only 11% available from San CM2 Alpha, while more than 99% of the creatine remained available from CM.

CEE is claimed to provide several advantages over CM because of increased solubility and stability. In practice, the addition of the ethyl group to creatine actually reduces acid stability and accelerates its breakdown to creatinine. This substantially reduces creatine availability in its esterified form and as a consequence creatines such as San CM2 and CE2 are inferior to CM as a source of free creatine.

Kre-alkalyn? supplementation has no beneficial effect on creatine-to-creatinine conversion rates.

All American Pharmaceutical and Natural Foods Corp. (Billings, MT, USA) claim that Kre-alkalyn? (KA) a ?Buffered? creatine, is 100% stable in stomach acid and does not convert to creatinine. In contrast, they also claim that creatine monohydrate (CM) is highly pH labile with more than 90% of the creatine converting to the degradation product creatinine in stomach acids. To date, no independent or university laboratory has evaluated the stability of KA in stomach acids, assessed its possible conversion to creatinine, or made direct comparisons of acid stability with CM.

This study examined whether KA supplementation reduced the rate of creatine conversion to creatinine, relative to commercially available CM (Creapure?). Creatine products were analyzed by an independent commercial laboratory using testing guidelines recommended by the United States Pharmacopeia (USP). Each product was incubated in 900ml of pH 1 HCL at 37? 1oC and samples where drawn at 5, 30 and 120 minutes and immediately analyzed by HPLC (UV) for creatine and creatinine.

In contrast to the claims of All American Pharmaceutical and Natural Foods Corp., the rate of creatinine formation from CM was found to be less than 1% of the initial dose, demonstrating that CM is extremely stable under acidic conditions that replicate those of the stomach. This study also showed that KA supplementation actually resulted in 35% greater conversion of creatine to creatinine than CM. In conclusion the conversion of creatine to creatinine is not a limitation in the delivery of creatine from CM and KA is less stable than CM in the acid conditions of the stomach.

Kas ka pasakys? Naudoti sena gera monohidrata ar visgi pazangesnius produktus?

Senas geras monohidratas all the way.

Pats pagalvok. Pirmu atveju tyrimus padarė pačios kompanijos, kurios daro produktą. Tai jos ten beleką gali pritirti, kad prastumti savo prekę. Antru atveju tyrimas atliktas nepriklausomoje labaratorijoje.
Kaip čia sakė, monohidratas all the way :-) Geriausas kainos ir efektyvumo santykis.

Sveiki, patartumete naudtori http://maistassportui.lt/index.php?cid=1162 sita creatina??

Patarciau kreiptis i pardaveja kuris turi nemazha procenta pelno ir uz ji gali apmoketi personalui kad tamstai duoti patarimus.

Kokia dar ok info. Paimtti ivairiu kreatinu reklaminiai lankstinukai ir nurasyta info, atseit palyginta, lol.

Kiek sveri, ir kam ta uzkrova darai?

Taip bandziau, 2 kartus su uzkrova, o dabar be uzkrovos geriu ir nesiskundziu. Ir kvapu nebereik skustis, nes uzkrovos metu pusdavo pilva
