Kidney Stones

Kidney stones, also known as nephrolithiases, are solid, insoluble crystalline structures that form in the kidneys or urinary tract, potentially causing severe pain and discomfort. Most smaller stones pass on their own, but larger stones may require medical treatment.

Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

30-60 mEq daily in divided doses (prescription; supplements have lower doses)

Increases urinary citrate (stone inhibitor); alkalinizes urine; prevents calcium and uric acid stones

20 studies | 2,000 participants
300-500mg daily (citrate form preferred)

Inhibits calcium oxalate crystal formation; binds oxalate in gut

12 studies | 800 participants

Supporting Stack (Tier 2)

25-50mg daily (do not exceed 100mg)

Reduces oxalate production; may help prevent calcium oxalate stones

8 studies | 500 participants
10-20 billion CFU with oxalate-degrading strains

Certain strains (Oxalobacter formigenes) degrade oxalate; may reduce oxalate absorption

6 studies | 300 participants
2-3g EPA+DHA daily

May reduce urinary calcium and oxalate excretion; anti-inflammatory

5 studies | 200 participants
120ml (4oz) lemon juice in water daily

Natural source of citrate; increases urinary citrate; pleasant way to increase fluid

6 studies | 250 participants

How It Works

Kidney stones are hard deposits of minerals and salts that form inside the kidneys. They can cause severe pain when passing through the urinary tract. About 10% of people will have a kidney stone, and without prevention measures, 50% will have another within 5-10 years.

TYPES OF KIDNEY STONES:

Calcium Oxalate (70-80%): Most common; form when calcium combines with oxalate
Calcium Phosphate (10-15%): Associated with high urine pH
Uric Acid (5-10%): Form in acidic urine; associated with gout
Struvite: Associated with infections
Cystine: Rare genetic disorder

RISK FACTORS:

Family history
Dehydration
High sodium diet
High animal protein diet
Obesity
Certain medical conditions (hyperparathyroidism, gout, diabetes)
Some medications and supplements (excess vitamin C, vitamin D)

SYMPTOMS:

Severe pain (flank, abdomen, groin)
Blood in urine
Nausea and vomiting
Frequent urination
Fever (if infected)

MOST IMPORTANT PREVENTION:

1. HYDRATION - 2.5-3 liters daily (urine should be light colored)

2. Dietary modifications based on stone type

DIETARY RECOMMENDATIONS:

Reduce sodium (<2300mg/day)
Moderate protein intake
Normal calcium intake (NOT low calcium!)
Limit high-oxalate foods if calcium oxalate stones
Reduce sugar and fructose

WHAT TO AVOID:

High-dose vitamin C supplements (>1000mg) - converts to oxalate
Excess vitamin D
High-oxalate foods (spinach, rhubarb, nuts) if prone to oxalate stones

* Potassium citrate is the most effective supplement for prevention.

* Magnesium helps inhibit stone formation.

* B6 may reduce oxalate production.

Expected timeline: Prevention is ongoing. Stone analysis guides specific recommendations.

Rheumatoid arthritis (RA) is an autoimmune disease that is mainly known for affecting the joints, but can also affect other parts of the body. It is more common in women than men and often starts during middle age, but it can occur at any age. The cause of RA is not well understood, but it seems to involve genetic, environmental, and hormonal factors.

Osteoarthritis (OA) is a joint disease involving cartilage degradation. It’s not clear what exactly causes OA, but some risk factors include joint injury, overweight or obesity, aging, misaligned joints, and family history. Lots of supplements have been studied in people with OA, as have lifestyle interventions including weight loss and exercise.
