Sachdeva says nutrient deficiency is one legitimate reason to use supplements: “When a physician prescribes supplements, laboratory results usually guide this [decision], and the recommendation mostly involves topping up levels of certain vitamins. … A physician might prescribe vitamin D for people with low vitamin D levels, or some people might need iron or other essential vitamins if levels are low.”
Ultimately, the best way to ensure you’re getting the amount of essential nutrients you need is through diet, and discussing these needs with a registered dietitian-nutritionist can help you enjoy a renal-safe diet that best supports your kidney health. “However, diet alone might not be enough to restore levels of certain vitamins in some people with deficiencies,” says Sachdeva.
