Traditionally, Ukulele strings were made of cat gut but in modern times, they have been more likely nylon or synthetic material. On rarer occasions, you can find Uke players strumming steel or metal wound strings.
Aquila Nylgut is on of the most popular strings with ukulele players. These strings are usually white and made with a proprietary composite material called nylgut. They are smooth, feel dry, and play a bright tone. Nylgut has become famous for making cheap ukuleles come alive with volume and presence. If you're not sure which strings to start with, it's hard to beat these.
Aquila recently released this Super Nylgut strings. This is the next step in synthetic gut strings, they provide a smooth and polished feel. They also should stay in tune longer than the original Nylgut strings due to a reduction in the stretch of each string. These strings produce a similar sound to Aquila Nylgut, but they should stay in tune longer and play truer, the downfall is they may not last as long.
The "Reds" are another relatively new string type, this string has been designed to have less variance in width across all 4 strings. They are very popular with Ukulele players who dislike the squeakiness of a wound low-G string and the blaring volume that goes with it. The biggest complaint these strings received is the low-G string, without the support of the wind, has been extremely brittle.
Worth Clear strings are usually highly recommended by heavy hitting players because they are made with fluorocarbon giving them a thin but sturdy feel. These strings are one of the most expensive as they are made and produced in Japan.

Ken Middleton, who is recognized from his many excellent YouTube videos, makes these strings. The strings are very similar to the Super Nylgut. They tend to be clear, very light, and louder than many other strings.
Ken designed these strings for his own use, but they've become a popular option for players of all skill levels.
D'Addario have classically been a guitar strings manufacturer that have branched into the Ukulele. They are a high-tension string though it doesn't affect the playability much at all. Even though they are made of nylon, they are slightly fatter than fluorocarbon. They produce good sound and are used by professional ukulele player and musician Jake Shimabukuro.
Another set of strings that are made from fluorocarbon. They hold for a long time due to their tune-to-pitch tension design and are nice and smooth on the fretboard. They are associated with just the right volume, sustain, and tone.

Very popular with Concert Ukulele players, these strings are the most popular Ko'olau make. They are made from traditional nylon and therefore tend to have a muted sound that is very warm. They are highly polished giving them a nice feel on the fretboard.
Ukulele players agree, these are some of the best strings you can find. We intentionally did not add any natural gut (cat gut) to this list due to the fact they are generally more expensive and don't play as well as many of the synthetics made today. We would, however, recommend you look into them if you would like to experience playing the "real thing".
