Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

2-4g EPA+DHA daily

Anti-inflammatory effects reduce pain signaling; may reduce NSAID requirements

25 studies | 1,500 participants
2000-4000 IU daily (higher if deficient)

Deficiency linked to chronic pain; supplementation may reduce pain especially in deficient patients

20 studies | 1,200 participants

Supporting Stack (Tier 2)

500-1500mg daily with piperine or phytosome form for absorption

Anti-inflammatory comparable to NSAIDs in some studies; reduces pain in osteoarthritis and other conditions

20 studies | 1,200 participants
300-500mg daily

NMDA receptor antagonist; reduces pain sensitization; helps with muscle tension and migraines

15 studies | 800 participants
600-1200mg daily in divided doses

Endocannabinoid-like compound; reduces inflammation and pain signaling; studied for neuropathic and chronic pain

15 studies | 800 participants
300-500mg standardized extract (AKBA) three times daily

5-LOX inhibitor with anti-inflammatory effects; studied for osteoarthritis and inflammatory pain

10 studies | 500 participants
600mg daily

Antioxidant with specific efficacy for neuropathic pain conditions

12 studies | 600 participants
B-complex daily (avoid >100mg B6)

B1, B6, B12 support nerve health; may help with neuropathic pain components

10 studies | 500 participants
800-1600mg daily in divided doses

May help with fibromyalgia and osteoarthritis pain; supports mood which affects pain perception

8 studies | 400 participants

How It Works

Chronic pain is pain lasting more than 3-6 months, persisting beyond normal tissue healing time. It affects about 20% of adults and can significantly impact quality of life, sleep, mood, and function. Chronic pain involves complex changes in the nervous system that make the pain system hypersensitive.

CRITICAL: Chronic pain requires a comprehensive, multimodal approach. Supplements are ONE component of a broader treatment plan.

COMPREHENSIVE PAIN MANAGEMENT includes:

Physical therapy: Movement, stretching, strengthening
Psychological support: CBT, mindfulness, pain acceptance
Medications: As appropriate for pain type
Interventional procedures: Nerve blocks, injections
Lifestyle modifications: Sleep, exercise, stress management
Complementary therapies: Massage, acupuncture

WHEN TO SEE A DOCTOR:

New or worsening pain
Pain with weakness, numbness, or bladder/bowel changes
Pain with fever or unexplained weight loss
Pain interfering with sleep, work, or daily activities

* Omega-3 Fatty Acids reduce inflammation throughout the body and may decrease the need for NSAIDs.

* Vitamin D deficiency is extremely common in chronic pain patients. Correction of deficiency often improves pain.

* Curcumin has anti-inflammatory effects comparable to NSAIDs in some studies, particularly for joint pain.

* Magnesium blocks NMDA receptors involved in pain amplification and may reduce central sensitization.

* PEA (Palmitoylethanolamide) is a naturally occurring compound that reduces inflammation and pain signaling.

Expected timeline: Anti-inflammatory supplements typically require 4-8 weeks to show benefit. A multimodal approach provides the best outcomes for chronic pain.

Weight Loss & Maintenance

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.

Type 2 Diabetes

3 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.

Overweight

3 shared supplements · 379 outcomes

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).

Obesity

3 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.

Immune health refers to the body's ability to resist potentially harmful microorganisms such as viruses and bacteria, and includes both innate and acquired immunity.

Chronic Obstructive Pulmonary Disease (COPD)

3 shared supplements · 51 outcomes

Chronic obstructive pulmonary disease (COPD) is a chronic disease of the lungs that involves airway damage and blockage that worsens over time. The progressively worsening airway blockage causes the main symptoms of COPD: difficulty breathing, cough, and mucus production. While the most common cause of COPD is smoking, other causes can include significant exposure to air pollutants, frequent respiratory infections, and untreated asthma. Standard COPD treatments include use of specific inhalers to relax and open up the airways.
