Kre-Alkalyn

[Binho-salsa 0]

Boa noite pessoal.

1- Gostaria de saber se a creatina Kre-Alkalyn da Labrada é boa?

2- Essa Kre-Alkalyn realmente promove o aumento muscular(massa magra) ??

3- Qual dose ideal? Diz que são duas cápsulas por dia, é realmente suficiente duas cápsulas? E qual melhor horário pra tomar com intuito de aumento muscular?

Grato pela atenção.

1 - Sim

2 - Não, assim como até a mono não promove aumento pelo simples uso dela. Se vai aumentar musculatura ou não é a dieta+treino que vai fazer diferença

3 - A recomendada pelo fabricante mesmo

PS: kre-alkalyn possui algumas criticas com base nessa pesquisa:

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.
