^ What Steve said.
Also, when you read the list of recommended RES foods, then, if it is on the list, it is okay for your RES to eat it. They are omnivores, and need a balance of many different nutrients. Calcium and Vitamin D3 are the most important, and it's best to feed an RES a commercial pellet which contains Vitamin D3.
Now, a human can naturally produce calcium, however, a turtle must get it from an outside source, like how they regulate their body temperature. Leafy greens, like romaine/boston/butterhead lettuce, red leaf lettuce, parsley, will provide appropriate sources of calcium. I normally don't feed a calcium supplement (cuttlebone) unless I see my turtles searching for it. Turtles will bite inedible objects, like tank decor excessively when they need calcium. I also provide calcium during shedding, whether they are searching for it or not. Don't over do it with the calcium supplements though, too much of anything is never good, and, since overproduction of calcium in humans can cause kidney stones, I'd imagine it may do the same in a turtle. I have to take one of mine to the vet tomorrow, so, I'm going to ask if this is definitely possible or not.
I always break cuttlebone into smaller bricks, depending on the size of my turtles. For example:
Hatchling under 4 inches in shell length: 1/2 inch block of cuttlebone.
Between 4 and 7 inches in shell length: 1 to 2 inch block of cuttlebone.
Over 8 inches in shell length: 2 to 3 inch block of cuttlebone, or one third of the larger block you purchased.
