Does whey protein affect the kidneys?

If your kidneys are healthy, you’re good to go with moderate whey protein. But if you're worried about potential risks, it's always a good idea to choose a high-quality whey protein. Higher-quality proteins, like those with minimal additives, artificial ingredients, and cleaner filtration methods, can be easier on your body overall.

I’ve heard this questions now so many time now and I, myself was once the victim of this fear. But there’s nothing wrong in being concern over your health before taking anything into your body.

Too much protein can make the kidneys work harder and could speed up kidney damage in people with conditions like chronic kidney disease (CKD).

When a dog smells another dog’s poo or wee, do they then remember that scent for when they smell it again, or even further know which dog they are smelling if they know the dog?

A study in the *American Journal of Kidney Diseases* found that high-protein diets might worsen kidney problems in those with CKD.

I’ll try to clear you doubts on this.

However, if you already have kidney disease, that’s a different story.

Do people really never face any hidden costs or surprises with surgeries in countries with single-payer healthcare like the NHS?

Hi all,

Whey protein, for most people with healthy kidneys, doesn’t really cause any issues.

And of course, if you have any kidney concerns or are planning to increase protein intake significantly, it’s always smart to check with a healthcare professional.

Research shows that when consumed in moderation, it’s generally safe and doesn’t harm kidney function. Your kidneys do filter waste from your blood, and while high protein intake can increase their workload a bit, there's no strong evidence that moderate whey protein consumption harms them.
