By "high amount" you mean above the recommended for a healthy diet? And I assume you mean protein as a powder, not by the proper food. So if we talk about powder - no, it isn't good to be consistently on a high dose or any dose, it's not good for the liver and the kidneys. But athlete or not, you should always get the necessary dose of it and the best way of doing it is by good quality food - in such case many supplements are even unnecessary.
Recommend protein consumption is subject to substantial myth and marketing scams. Supplement companies have driven the myth that you need at least 1g of protein per pound of your body weight. It’s just absolute bull**** with no scientific grounding and it has just been pushed by supplement companies to encourage people to waste money on protein supplements. 80-100g of protein daily is most likely more than enough for muscle growth and recovery whether you’re trying to build muscle, lose weight or just get stronger. I know this myself because I’ve experimented with different amounts of daily protein consumption and it’s had no real difference. In bodybuilding, Danny Padilla who was a terrific bodybuilder used to make a point of consuming only about 80g of protein a day while his competitors used to have around 250-300g and it made no difference on the stage. Sure he was juiced up but protein is still required for muscle building. I see a lot of female fitness IGers boasting about having up to 200g protein a day and just laugh. It’s a total waste of money. An unnecessary burden on the kidneys. Of course there’s nothing wrong with having more protein if the goal is to keep yourself satiated but it’s a tremendous waste of money when you see average joes eating 200g+ a day. Personally I range between about 160-170g a day and that’s basically just because I enjoy fish and meat. If you are a natural drug free athlete, it’s more important to keep your fat intake high whilst low in saturated fats. Eat at least 75g of fat daily IMO.
