Osteoarthritis (OA)
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.
Quick Answer
What it is
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.
Key findings
- Grade A: Knee Osteoarthritis Pain (vs NSAID) (Systemic Enzymes (Bromelain/Trypsin/Rutin))
- Grade A: Joint Function in Osteoarthritis (Systemic Enzymes (Bromelain/Trypsin/Rutin))
- Grade A: Safety vs NSAIDs (Systemic Enzymes (Bromelain/Trypsin/Rutin))
Safety
- It’s not clear what exactly causes OA, but some risk factors include joint injury, overweight or obesity, aging, misaligned joints, and family history.
- RCT (n=150): Adverse events similar to placebo (7.2% vs 9.1%) and lower than diclofenac (15.6%).
- RCT vs diacerhein: Significantly lower adverse event rate.

Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Provides building blocks for cartilage repair, inhibits degradative enzymes, and stimulates proteoglycan synthesis
Potent anti-inflammatory that inhibits NF-κB, COX-2, and MMPs while protecting cartilage from degradation
Supporting Stack (Tier 2)
Boswellic acids inhibit 5-lipoxygenase and leukotrienes, reducing inflammation and protecting cartilage
Inhibits IL-1 induced collagenase and stromelysin, promoting cartilage repair and reducing inflammation
Undenatured collagen induces oral tolerance, reducing autoimmune cartilage destruction
Provides sulfur for connective tissue synthesis and has anti-inflammatory and antioxidant properties
EPA/DHA reduce pro-inflammatory eicosanoids and cytokines, decreasing joint inflammation
How It Works
Osteoarthritis is a degenerative joint disease where cartilage—the smooth tissue that cushions your joints—breaks down over time. This causes pain, stiffness, and reduced mobility. Unlike inflammatory arthritis, OA is primarily a 'wear and tear' condition, though inflammation does play a role. This protocol targets both cartilage protection and inflammation reduction.
Expected timeline: Boswellia and curcumin may show benefits within 1-4 weeks. Glucosamine/chondroitin require 8-12 weeks. Type II collagen: 4-8 weeks. ASU: 2-3 months for full effect.

Metabolic Health
14 shared supplements · 975 outcomes
Research on metabolism, blood glucose regulation, insulin sensitivity, and metabolic syndrome.
Type 2 Diabetes
12 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
11 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.
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.

Overweight is characterized as having a body mass index (BMI) of 25 to 29.9. Having overweight is associated with increased risk of conditions such as cardiovascular disease. However, this may not be the case in people with increased lean mass (e.g., athletes or weight lifters).
