How Kidney Stones Form Your kidneys are filters. All day long, they clean your blood and make urine.

What’s going on inside your kidneys Your kidneys don’t just make urine, they remove extra acid from your body and keep things balanced by using natural helpers called buffers. Buffers work like baking soda in your fridge. They soak up extra acid so things don’t get too sour inside your…

Why Some People Can Eat More Meat (and Why Others Make More Stones) One of the most confusing aspects of kidney stones is that two people can eat the same amount of meat, yet only one develops stones. The difference isn’t willpower, metabolism, or doing something “wrong.” The difference is…

First, most vitamins don’t increase the risk of kidney stones. Two do: vitamin C and sometimes vitamin D. Everything else? Usually harmless at normal doses. Here’s what stone formers actually need to know. Vitamin C In food, great. In supplements over 200 mg/day? A hard no. Excess vitamin C can…

When you eat too much sodium, that balance tips too far in one direction.…

Keto, paleo, carnivore, and low-carb diets can help with weight or blood sugar—but they also shift your body chemistry in ways that quietly raise your kidney stone risk. Not always, not for everyone, but often enough that you should know what’s going on. Especially if you are a past kidney…

For those of you who have a hard time getting in your water, slowly increase your intake week by week until you get used to it. Your bladder is a muscle; it will need to adjust. You want to drink enough water to produce at least 2.5 liters of urine…

Why calcium pills can raise stone risk Calcium supplement pills deliver a concentrated bolus of calcium (usually carbonate or citrate).
