You have used comparatives but it would be better to either use the absolute form of this adjective "best," or to use a different adjective. I would suggest: "You need the best ingredients to make the best products," or "Only quality ingredients can be turned into quality products." Or you could mix best/quality in the sentence - "Only the best ingredients can lead to the production of quality products."

Hi Janell, As you are not providing specific details of the ingredient used and the intended product, you can eliminate the word "the". In my opinion, it is fine to use comparatives here. It is understood that you are comparing two "types" of ingredients -- inferior versus superior ingredients. The phrase "can make" sounds odd here, as it gives the impression that someone is making something here. Suggestion: Better ingredients create better products. Having said that, using superlatives will make an even more impactful statement. The word "the" is used in this case, as we are very specific now in choosing the best. The best ingredients create the best products. Hope this helps. Cheers, Lance
