Uhm, litt effekt ja, men karbohydrater finnes som regel eller alltid(?) i kreatin uansett, Blandt annet No-Xplode består av 7% karbohydrat, og inneholder maltodextrin.
Maltodextrin er bare raske karbohydrat som fåes f.eks ved karbohydrattilskudd.
Eneste studien jeg fann på karbohydrat og kreatin er denne, som er ble gjort i 1996.
Ang kreatin og karbohydrat.

Blood and urine samples were obtained from four groups of healthy male subjects (A–D, total n=22) before, during and after ingesting the following: group A, 5 g of creatine in solution; groups B and C, 5 g of creatine and 93 g of simple carbohydrate in solution; group D, a creatine- and carbohydrate-free solution. Subjects ingested the above preparations every 4 h for the remainder of the day and throughout the next day (total daily creatine dose=20 g), and reported back to the laboratory on day 3 to undergo the same procedures as on day 1. Throughout this time, subjects weighed and recorded all dietary intake, and those in groups B and C ingested a prescribed isoenergetic high carbohydrate diet. Subjects in group C also performed 1 h of cycling exercise at 70% of their maximal oxygen consumption on the morning of each day. On both days 1 and 3, peak plasma creatine concentration, the area under the plasma creatine concentration/time curve and urinary creatine concentration were lower in groups B and C than in group A. Conversely, serum insulin concentration was higher in groups B and C than in A. No differences were evident when comparing groups B and C. These data suggest carbohydrate ingestion augmented creatine retention during creatine feeding and that creatine retention was not further increased when exercise was performed prior to ingestion.
Btw:
1. Maltodextrin
As with the initial line of creatine enhancing
supplements, maltodextrin is still being
used in many of the creatine transport sys-
tem supplements for its ability to increase
blood insulin levels and enhance creatine
uptake by muscle cells. The primary differ-
ence with sugar content in the newer prod-
ucts is that they are using less total sugar
then the original products to hopefully de-
crease the likelihood of carbohydrate being
stored as fat
Når jeg skrev innlegget over så tenkte jeg på større mengder karbohydrater samt tregere.
Opptak av kreatinet sammen med maltodextrin vil føre til et bedre opptak som undersøkelsen over viser.
Men uansett, karbohydrater er tilsatt i kreatinen fra før av pga av dette, som jeg skrev lenger oppe.
I undersøkelsen brukte de 93 g karbohydrat (trolig maltodextrin), men om det er nødvendig med så mye eller om det holder med det som er i kreatinen fra før, blir et annet spørsmål igjen. Men i det store og hele er tror jeg ikke du vil merke noe forskjell om blander med ekstra maltodextrin eller ikke.
