I agree totally with MR. X on this one. I take creatine all throughout the week on my CKD diets. Of course it doesn't work as well while your in ketosis, but it does seem to help. And of course, the weekend intake is really awesome, giving great pumps, both over the weekend and during your early week workouts.
Here's a quote that cockdezl wrote about a year ago on taking vitamin C to increase solubility of creatine:
"Vitamin C will increase solubility of creatine due to the low pH. Usually I make 2 liters of a Crystal Light mix and add about 2-4 grams of Vit C and then 5-10 grams of creatine. If anyone remembers the shortlived creatine citrate, this was the rational: Lower pH for greater solubility."
He went on to add,
"...ALA should help creatine absorbtion since its mechanism seems to be an increase of non-insulin glucose transporters on the cell surface."
