Chronic Kidney Disease (CKD)

Chronic kidney disease (CKD) is a degenerative disease of the kidneys. In addition to medication, CKD is managed nutritionally with diets that modify the intake of specific nutrients affected by impaired kidney function.

Quick Answer

What it is

Chronic kidney disease (CKD) is a degenerative disease of the kidneys. In addition to medication, CKD is managed nutritionally with diets that modify the intake of specific nutrients affected by impaired kidney function.

How It Works

Chronic Kidney Disease means the kidneys are gradually losing their ability to filter waste and excess fluid from the blood. CKD dramatically increases cardiovascular risk and causes numerous complications including anemia, bone disease, and accumulation of toxins. While supplements cannot reverse kidney damage, they can address complications and may slow progression.

•Omega-3 Fatty Acids help protect the heart—critical since cardiovascular disease is the leading cause of death in CKD. They reduce inflammation (elevated in CKD), improve blood lipids, and some studies suggest they may slow kidney function decline.
•Coenzyme Q10 supports cellular energy production and acts as an antioxidant. Oxidative stress is markedly elevated in CKD and contributes to complications. Studies show CoQ10 may improve kidney function markers and reduce inflammation.
•Vitamin D deficiency is nearly universal in CKD because the kidneys convert vitamin D to its active form. Deficiency contributes to bone disease, cardiovascular problems, and immune dysfunction. Supplementation is often essential but may require the active form (calcitriol) as CKD progresses.
•Probiotics address the disrupted gut microbiome in CKD. An unhealthy gut produces uremic toxins that the failing kidneys cannot clear. Specific probiotic strains can reduce these toxins and lower inflammation.

Expected timeline: Benefits develop over weeks to months with consistent use. Vitamin D should be monitored and adjusted based on blood levels.

Critical: Always work with your nephrologist. Many supplements can be harmful in kidney disease—these have been selected for safety, but dosing may need adjustment based on kidney function.

Type 2 Diabetes

16 shared supplements · 868 outcomes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

High Cholesterol

12 shared supplements · 553 outcomes

High amounts of low-density lipoproteins cause fatty plaques to build up in the arteries, which restricts blood flow and can cause health problems like a heart attack. Lifestyle factors (e.g., poor diet, smoking) and genetics play a huge role in blood cholesterol levels.

High Blood Pressure

11 shared supplements · 393 outcomes

High blood pressure is when the force of your blood pushing against the walls of the arteries is consistently too high. High blood pressure is often caused by an unhealthy lifestyle, although it can result from other medical conditions as well.

Obesity

10 shared supplements · 525 outcomes

Obesity is a condition of excessive body fat that increases the risk for other conditions such as diabetes and heart disease. Fat is how the body stores extra calories that were eaten but not used. Obesity treatment usually involves restricting the calories eaten or creating a negative calorie balance.

Metabolic Syndrome

10 shared supplements · 391 outcomes

Metabolic syndrome refers to a group of cardiometabolic risk factors: abdominal obesity, high blood pressure, high fasting blood sugar, high blood triglycerides, and low HDL-C. If a person has at least three of these, they have metabolic syndrome.

Weight Loss & Maintenance

9 shared supplements · 433 outcomes

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.
