What is Prolozone Therapy?

Prolozone Therapy is a regenerative injection technique developed by Dr. Frank Shallenberger that delivers a precise blend of ozone gas, vitamins, and natural anti-inflammatory compounds directly into painful joints, tendons, discs, or soft tissues. The name combines 'prolo' — short for proliferative — with 'ozone,' reflecting the therapy's goal of stimulating the body's own repair processes rather than just masking pain. It is practiced by integrative and naturopathic physicians and is used for musculoskeletal conditions that have been resistant to physical therapy, medications, or steroid injections.

How does Prolozone Therapy work?

When ozone is injected into damaged tissue, it triggers a controlled, localized oxidative signal that prompts cells to ramp up their natural healing and energy production. This boost in cellular activity helps restore the oxygen supply to oxygen-starved (hypoxic) tissues — a key reason why injuries become chronic in the first place. The accompanying nutrients and homeopathic agents reduce inflammation and support connective tissue rebuilding, making the environment far more favorable for lasting repair.

What forms does Prolozone Therapy come in?

Prolozone is delivered entirely by injection and is tailored to the body part being treated. Knee, hip, shoulder, wrist, and ankle joints receive intra-articular injections. Spinal discs and nerve roots can receive epidural or intradiscal injections. Tendons and ligament attachments receive periarticular injections, and trigger points in muscles can also be treated. The injection protocol, volume, and ozone concentration are individualized by the treating physician.

Where it comes from:

Prolozone was formalized as a distinct therapy by Dr. Frank Shallenberger, MD in the early 2000s, building on decades of ozone therapy research originating in Europe — particularly Germany and Italy — where ozone-oxygen injections for musculoskeletal pain have been practiced since the 1980s. It evolved from classical prolotherapy (dextrose injections) by adding ozone's regenerative oxidative signal, creating a hybrid approach that practitioners report produces faster and more durable results than either therapy alone.

What does Prolozone Therapy help with?

• Chronic knee pain and osteoarthritis: Prolozone injections into the knee joint help reduce inflammation and stimulate cartilage-supporting cells, which may slow tissue breakdown and improve joint cushioning. Patients commonly report meaningful reductions in pain and improved mobility, including the ability to walk farther or climb stairs with less discomfort.
• Low back pain and disc herniation: Chronic low back pain is often driven by poor oxygen delivery to discs and surrounding ligaments, which keeps the area stuck in a healing deficit. Prolozone injections around the lumbar spine or directly near the disc improve local circulation and cellular repair, helping to reduce nerve irritation and restore function.
• Shoulder pain and rotator cuff injuries: Tendons and ligaments around the shoulder have notoriously poor blood supply, which makes them slow to heal on their own. Prolozone delivers the oxidative signal and nutrients these tissues need to restart the repair process, with many patients experiencing less pain and greater range of motion after a course of treatment.
• Hip pain and osteoarthritis: For hip arthritis and bursitis, prolozone injections aim to reduce joint inflammation and stimulate regeneration of the joint lining and surrounding connective tissue. Clinical reports suggest it can provide meaningful pain relief and delay or reduce the need for surgical intervention.
• Neck pain and cervical disc problems: Cervical disc degeneration and facet joint inflammation are common sources of chronic neck and arm pain. Prolozone injections into the cervical facets or epidural space help calm the inflammatory cycle and support tissue repair, often reducing both local neck pain and referred symptoms down the arm.
• Tendinopathy and tendon injuries: Chronically degenerated tendons — like Achilles tendinopathy or patellar tendinopathy — often fail to heal because of inadequate oxygen and growth factor signaling. Prolozone re-introduces the oxidative stimulus that triggers tendon fibroblasts to rebuild collagen, helping to restore tendon strength and reduce pain.
• Ligament laxity and sprains: Loose or repeatedly sprained ligaments can destabilize joints and create chronic pain cycles. Prolozone, like traditional prolotherapy, is designed to tighten and strengthen ligamentous attachments by stimulating localized tissue proliferation, helping stabilize the joint over a series of treatments.
• Plantar fasciitis: When the thick connective tissue on the bottom of the foot becomes chronically inflamed and degenerative, standard treatments often provide only temporary relief. Prolozone injections into the plantar fascia and heel attachment can accelerate tissue repair and reduce pain, particularly in cases that haven't responded to stretching, orthotics, or cortisone.
• Fibromyalgia and widespread musculoskeletal pain: Some practitioners use prolozone to treat the most painful trigger points and joint areas in fibromyalgia patients. The combination of ozone and procaine can help break the pain-spasm cycle in localized areas, and when combined with broader integrative care, may contribute to overall pain reduction.

What can Prolozone Therapy help prevent?

• Progression of joint degeneration in early-to-moderate osteoarthritis when used as part of a comprehensive joint health program
• Repeat musculoskeletal injury in areas of ligament laxity by restoring structural stability

Which foods are rich in Prolozone Therapy?

Prolozone is an injectable therapy and cannot be obtained through food. However, several dietary strategies directly support the tissue repair and ozone-response pathways this treatment targets. Prioritize vitamin C-rich foods (citrus, bell peppers, strawberries) because vitamin C is essential for collagen synthesis — the same process prolozone aims to stimulate. Sulfur-rich foods like eggs, onions, garlic, and cruciferous vegetables support connective tissue crosslinking and have natural anti-inflammatory properties. Omega-3 fatty acids from fatty fish (salmon, sardines, mackerel) and walnuts help reduce the chronic joint inflammation that prolozone works to resolve. Bone broth provides glycine, proline, and hydroxyproline — the amino acid building blocks of collagen and cartilage. Antioxidant-rich foods (berries, dark leafy greens, beets) help the body manage the mild oxidative signals that ozone therapy relies on without tipping into harmful oxidative stress. Avoid ultra-processed foods, refined sugars, and vegetable oils high in omega-6 fats, as these promote the chronic inflammation that slows tissue repair.

What are the side effects of Prolozone Therapy?

• Temporary soreness, aching, or swelling at the injection site (very common, usually resolves within 24–72 hours)
• Mild bruising at the injection site
• Temporary flare of the treated pain (can occur in the first 1–2 days and is often considered part of the healing response)
• Skin redness or warmth around the injection site
• Lightheadedness or vasovagal response during the injection (uncommon)
• Headache, particularly after cervical or spinal injections (uncommon)
• Infection at the injection site (rare with proper sterile technique)
• Nerve irritation or temporary worsening of radiating symptoms after spinal injections (rare)
• Pneumothorax risk with thoracic injections if improperly placed (rare, technique-dependent)

Good to know:

Prolozone is considered a low-risk procedure when performed by a trained practitioner using sterile technique. The most common effects are mild and short-lived. Serious adverse events are rare but possible, particularly with spinal injections, which is why provider training and experience matter greatly.

How much Prolozone Therapy should you take?

• Recommended daily: Typically 1 injection session per affected area every 2–4 weeks; each session involves 1–5 mL of ozone-nutrient solution per injection site at an ozone concentration of 10–40 mcg/mL, titrated by the provider to the tissue and patient tolerance.
• Best time of day: Sessions are performed in a clinical setting at whatever time is scheduled with your provider; no time-of-day restriction applies.
• With or without food: Eating a light meal before treatment is recommended to reduce the risk of lightheadedness or vasovagal response during the injection.
• Time to effect: Initial improvement is often noticed within the first 24–72 hours after the first or second session; meaningful functional improvement typically builds over a course of 3–6 sessions spanning 2–4 months.
• How long to take it: A standard initial course is 4–6 sessions. Many patients achieve durable results and require no further treatment or only occasional maintenance injections (every 6–12 months). The need for additional sessions is reassessed based on symptom response after each treatment.
