Kidney Health

Kidney health refers to the ability of the kidneys to filter blood, produce hormones, remove waste products, produce urine, regulate acid-base balance, and maintain the body’s proper balance of minerals and electrolytes.

Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

2-4g EPA+DHA daily

May reduce inflammation and proteinuria; supports cardiovascular health in CKD patients

20 studies | 2,000 participants
100-500mg daily

Antioxidant and anti-inflammatory that may protect kidney function and reduce oxidative stress

10 studies | 500 participants

Supporting Stack (Tier 2)

1000-2000 IU daily (active vitamin D if advanced CKD)

Deficiency very common in CKD; supplementation important but requires monitoring

25 studies | 3,000 participants
100-200mg daily

Antioxidant that may reduce oxidative stress and support mitochondrial function in kidney cells

8 studies | 400 participants
10-20 billion CFU daily

May reduce uremic toxins by modulating gut microbiome in CKD patients

15 studies | 800 participants
As prescribed based on bicarbonate levels (typically 650-1300mg 2-3 times daily)

Corrects metabolic acidosis in CKD; may slow disease progression

15 studies | 1,200 participants

Antioxidant that may protect kidneys from oxidative damage, especially in diabetic nephropathy

8 studies | 400 participants
600-1200mg daily

Glutathione precursor that may protect against contrast-induced nephropathy and oxidative stress

15 studies | 1,500 participants
Kidney-friendly B-complex as directed

Addresses elevated homocysteine common in CKD; supports overall metabolism

10 studies | 800 participants

How It Works

Kidney health is crucial as the kidneys filter waste, balance fluids, regulate blood pressure, produce hormones, and maintain mineral balance. Chronic kidney disease (CKD) affects about 15% of adults and can progress silently to kidney failure. Risk factors include diabetes, high blood pressure, heart disease, and family history. While preventing progression requires managing underlying conditions, certain supplements may support kidney function and address complications.

CRITICAL: CKD requires nephrology care. Many supplements need dose adjustment or are contraindicated in kidney disease. Avoid high-dose vitamin A, potassium supplements, and excessive protein without guidance. Some herbal supplements can be nephrotoxic. ALWAYS discuss supplements with your nephrologist before taking them.

* Omega-3 Fatty Acids may help reduce inflammation and proteinuria (protein in urine) in kidney disease. They also support cardiovascular health, which is especially important since heart disease is the leading cause of death in CKD patients.

* Resveratrol has antioxidant and anti-inflammatory properties that may protect kidney cells from damage. Research suggests it may help preserve kidney function, particularly in the context of diabetes-related kidney disease.

* Vitamin D deficiency is extremely common in CKD because the kidneys normally activate vitamin D. Low vitamin D contributes to bone disease, muscle weakness, and cardiovascular risk. Supplementation is often necessary but requires monitoring, and advanced CKD may require active vitamin D (calcitriol or analogs).

* CoQ10 supports mitochondrial energy production and has antioxidant effects. It may help reduce oxidative stress that contributes to kidney damage.

* Probiotics are increasingly recognized as beneficial in CKD. The gut microbiome is altered in kidney disease, producing uremic toxins. Probiotics may reduce these toxins and improve symptoms.

* Sodium Bicarbonate helps correct metabolic acidosis, a common complication of CKD that can accelerate disease progression and worsen bone and muscle health.

* Alpha-Lipoic Acid may help protect against diabetic nephropathy through its antioxidant effects.

* NAC provides cysteine to make glutathione, the body's major antioxidant. It may help protect kidneys from contrast dye damage and oxidative stress.

* B Vitamins help address elevated homocysteine levels common in CKD and support overall metabolism. CKD patients often need supplementation, but water-soluble vitamins are lost during dialysis.

Expected timeline: These supplements provide ongoing support. Effects on kidney function parameters may take months to assess. Vitamin D: check levels in 8-12 weeks. Acidosis correction: monitor bicarbonate levels. Work closely with your nephrologist for monitoring.

Body composition refers to the relative percentage of fat, muscle, and bone in someone’s body. Body composition is sometimes reported as fat and fat-free mass.

Type 2 Diabetes

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.

Obesity

5 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.
