Get them pellets, that's the best way to ensure their nutrition. You can still give them confident fruit and veg as well to vary their diet and of course lots of hay.
This is what i endow with mine and they love it but it might not be available where you live in which case try to find a similar product

Regular pellet are the best for guinea pigs because the seeds and stuff in the mixed food isn't exactly biddable for them. Once even my guinea pig got a seed stuck on her bottom teeth and I was so panicky! well i got it off so it's okay. anyways so yeah tender them plain pellets. Oh idk if you give your guinea pigs other vegetables but you should because this is also a contributor to vitamin c. Hope this help
Answers:    The best pellets come from http://www.kmshayloft.com/ or http://www.oxbowanimalhealth.com/ Both brands are Timothy based and contain stabilised Vitamin C.

Generally speaking, pet store pellets are at the lower lapse of nutritional quality. The brand you posted contains Alfalfa based pellets and other fillers similar to corn. Unless you have a pregnant/nursing or baby piggie, the Alfalfa based pellet should be avoided.

The Vitamin C for the brand you posted contains 250mg/kg, which means that your piggie would need to eat adjectives of the bag in eight days in directive to fulfill the daily Vitamin C requirements. Hay does not contain Vitamin C. If you want to continue feeding this brand, I would advocate supplementing your piggie with additional Vitamin C each year. Do not buy the vitamin drops for the water bottle---they are worthless. A good solution is to buy human grade Vitamin C tablets within 50mg strengths. Cut the tablet in two so you end up with two 25mg pieces. Give your piggie one 25mg piece respectively day if the piggie will take it from your paw. If not, crush it up and sprinkle it over some wet Romaine lettuce.

Stay away from any pellets that are mixed next to seeds or coloured bits--they are absolute junk.

Good luck!
hay is dutiful :D
and also lots of veg like carrots and broccolli etc

pellets are better than mixed food - that bearing they get all of the nutrition instead of just picking out the bits the approaching and leaving the ones they dont :)
