Creatine needs to be taken with grape juice.
The concept behind taking creatine with sugar such as grape juice is sound. But the trick is not the grape juice per serving. It has to do with insulin's function in the body. For creatine uptake to be enhanced, insulin release should be encouraged. Insulin functions as a kind of creatine pump, pushing it into muscles. If you're going to stick to juice, make sure you get at least 100g of juice for every 5g of creatine. Depending on your level and your goals, juice loaded with sugars may not be suitable. Newer research indicates that you can take your creatine with protein for the same results. A new study reports that taking 5g of creatine with 50g of protein/47g of carbs produced the same results as taking 5g with 96g of carbs.
